ATSAMD51J20A-AU

ATSAMD21G18A-AU is a 32-bit Arm Cortex-M0+ microcontroller from Microchip (SAMD21 family) in TQFP-48 — with native full-speed USB for battery-powered and USB-peripheral designs. The on-chip USB is the selection point: it removes the external USB bridge chip that simpler MCUs need. Selection advice: the G18A denotes the 256 KB Flash / 32 KB SRAM variant — pick it when you need USB plus headroom for stacks; drop to a smaller SAMD21 for cost. The -AU suffix denotes the TQFP-48 package; -U at the end is the standard temperature grade. This is a mature line with broad ecosystem support.

ATSAME54P20A-AU is a Microchip SAME54 120 MHz Arm Cortex-M4F microcontroller — for industrial Ethernet nodes, gateways and PLCs: 1 MB flash, 256 KB SRAM, 10/100 Ethernet MAC, USB high-speed, CAN FD, and SERCOM peripherals in 100-pin TQFP. The E54 line is the Ethernet step-up from the SAMD51 on this site — same Cortex-M4F core, plus the MAC and larger peripheral set industrial networking demands. Selection advice: the P20A-AU code is the 100-pin TQFP — for 64-pin designs the P19A is the smaller twin; for USB-only without Ethernet the SAMD51J20A on this site costs less. Microchip's MPLAB Harmony framework covers the Ethernet stack — confirm the PHY pairing (RMII/MII) against your magnetics. Parameters verified against Microchip documentation and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AM2434BSDFHIALVR is a Texas Instruments Sitara AM243x high-performance MCU: up to four 800 MHz Arm Cortex-R5F cores, a 400 MHz Cortex-M4F, and dual gigabit PRU-ICSSG industrial-communication subsystems in a 441-ball FCBGA (17.2 x 17.2 mm). It is TI's consolidation play for factory automation — the R5F cluster delivers deterministic servo-loop control while the PRU-ICSSG runs full protocol stacks for EtherCAT target, PROFINET device and EtherNet/IP adapter on the same silicon, replacing architectures that needed an MCU plus an external industrial-Ethernet ASIC or FPGA. Heat evidence: the AM243x is TI's mainstream platform for servo drives and remote I/O modules, and its datasheet remains under active revision (Rev. J, 2026), signaling continued TI investment in the family. Selection advice: the full orderable encodes silicon revision, feature configuration, temperature grade and the ALV 441-ball FCBGA package on tape and reel — match it character-for-character; the ALX 293-ball FCCSP is a smaller, footprint-incompatible alternative, and R5F count plus PRU features vary across AM2431/32/34. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AM6232ATGGHIALWR is a Texas Instruments Sitara AM62x processor: dual 1.4 GHz Arm Cortex-A53 plus a Cortex-M4F in a 425-ball FCCSP (13 x 13 mm). The value proposition is Linux-class compute at microcontroller-class power — the A53 pair runs full Yocto/Debian HMI stacks while the M4F handles real-time I/O, so one device replaces an applications processor plus a companion MCU in industrial panels and gateways, and deep-sleep states in the milliwatt class simplify thermal and power design. TI's long-lifecycle industrial positioning protects multi-year programs from forced redesigns. Heat evidence: the AM62x family has been one of TI's most heavily promoted industrial platforms since its 2022 launch, with broad trade-press coverage and multiple third-party system-on-module vendors building AM62x-based products for HMI and edge AI. Selection advice: the ALW FCCSP-425 is the compact package variant — the AM625/AM623/AM620-Q1 family shares one TI product folder, so confirm the exact orderable against the datasheet because family members differ in feature set; the G temperature code and W carrier suffix must match your assembly flow. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

CH32V307VCT6 is a RISC-V microcontroller from WCH in a 100-pin LQFP package — the high-end of the CH32V line for I/O-heavy embedded control. The 100-pin RISC-V option is the selection point: maximum peripherals and pins on the open RISC-V architecture, for designs that want ARM-class I/O without ARM licensing cost in the BOM. Selection advice: the VCT6 suffix denotes this density and the LQFP-100 package — match the full code. Confirm your toolchain supports the WCH RISC-V core and verify peripheral requirements against the datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

CY8C4125LQI-483 is an Infineon (Cypress) PSOC 4100 microcontroller in the PSOC 4 family. It combines an Arm Cortex-M0 core with 32 KB Flash, 4 KB SRAM and 34 GPIOs in a 40-pin QFN package. The device includes CapSense and LCD direct-drive functionality. Confirm the complete ordering code, pin assignment, supply requirements and package dimensions against your board design. For project development, this legacy device uses PSOC Creator rather than the ModusToolbox development environment; confirm device support in the tool version used for your project. Include the full part number, quantity, packing format and any date-code or inspection requirements in your RFQ. Availability and delivery terms are confirmed with the quotation.

GD32F103C8T6 is an Arm Cortex-M3 microcontroller from GigaDevice with 64 KB Flash in a 48-pin LQFP package — a pin-compatible alternative to the STM32F103C8T6 for embedded control. Pin compatibility is the procurement advantage: it offers a second source for the same footprint, which de-risks supply without a board redesign. Selection advice: pin-compatible does not mean software-identical — peripheral details, Flash timing and errata differ between vendors, so firmware must be validated on the GD32 before committing. Match the full GD32F103C8T6 code to your BOM and confirm your firmware qualification covers this specific device. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LPC1768FBD100 is an NXP Semiconductors Arm Cortex-M3 microcontroller in LQFP-100 — for Ethernet-connected embedded designs: industrial gateways, access control and instrumentation. The on-chip Ethernet MAC plus USB and CAN is the selection point: full connectivity without external controllers. Selection advice: the FBD100 denotes LQFP-100 — confirm your network stack (e.g., lwIP) fits the 512 KB Flash / 64 KB SRAM; for new designs, compare NXP's newer i.MX RT crossover MCUs for more headroom. A mature line with long availability. Parameters verified against the NXP official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LPC55S69JBD100 is an NXP dual-core ARM Cortex-M33 microcontroller at 150 MHz — 640 KB Flash, 320 KB SRAM in 100-pin HLQFP. The selection point is security plus DSP: ARM TrustZone, AES-256/SHA-2 crypto accelerators, secure boot, and a PowerQuad DSP coprocessor for motor control and audio front-ends. Selection advice: the JBD100 code is the 100-pin HLQFP — for 64-pin designs the JBD64 is the smaller twin, and the JEV98 VFBGA suits space-constrained boards. The S69 is the full-feature variant; the S66 drops the second core for cost-sensitive designs — match the security and DSP requirements before substituting. Parameters verified against NXP documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

M0516LDN is a Nuvoton NuMicro M051 series 32-bit microcontroller in 48-pin LQFP, tray packing — Arm Cortex-M0 core up to 50 MHz, 64 KB Flash plus 4 KB SRAM plus 4 KB Data Flash with ISP/ICP/IAP support, 8-channel 12-bit SAR ADC up to 760 kSPS, 2× UART, 2× SPI, 2× I²C, 8-channel PWM, 2.5 V to 5.5 V supply, rated −40 °C to +85 °C. The 2.5–5.5 V wide supply with 5 V-tolerant I/O is the selection point: mixed 3.3 V/5 V industrial boards run this MCU without level shifters, and the 5 V operation gives extra noise margin in electrically noisy control cabinets. Selection advice: the LDN code is the LQFP-48 tray version with 64 KB Flash — the M0516ZDN is the same silicon in QFN33 for smaller boards, the M058LDN is the 32 KB Flash sibling in the same LQFP-48 if your firmware fits. DigiKey lists this code Active. Evidence: the Nuvoton official product page and M051 reference manual confirm the ordering code, 50 MHz Cortex-M0, memory sizes and LQFP-48 package. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
