STM8S003F3P6TR

STM8S003F3P6 is an STMicroelectronics 8-bit microcontroller with 8 KB Flash in TSSOP-20 — for the simplest control tasks: button interfaces, LED sequencing and basic sensor polling. The low price is the selection point: among the lowest-cost programmable control ST offers. Selection advice: the F3 denotes 8 KB Flash — for anything beyond trivial logic, the STM32F030 or G030 32-bit lines cost little more and buy a modern toolchain; reserve the STM8 for true cost-floor designs. The P6 denotes TSSOP-20. Parameters verified against the ST official product page.

ATMEGA2560-16AU is a high-pin-count 8-bit AVR microcontroller from Microchip Technology with 256 KB Flash in a 100-pin TQFP package — for I/O-heavy embedded control. The 256 KB Flash with 100-pin I/O is the selection point: the largest AVR 8-bit device, the chip behind the Arduino Mega, for designs that outgrew smaller AVRs but want to stay in the 8-bit ecosystem. Selection advice: the 16AU suffix denotes the 16 MHz speed grade in TQFP-100 — match the full code to your layout and clock requirements. If your firmware fits in 128 KB, the ATMEGA1280 is the cheaper drop-in alternative in the same package.

ATMEGA328P-AU is an 8-bit AVR microcontroller from Microchip Technology in a 32-pin TQFP package — for embedded control and instrumentation. This is the chip behind the Arduino Uno: the largest hobbyist and educational ecosystem of any microcontroller, which means code examples and libraries for nearly every sensor. Selection advice: the AU suffix denotes TQFP-32 — the ATMEGA328P also ships in PDIP-28 (PU suffix), so match the full ATMEGA328P-AU code to your layout. The P (picoPower) variant is the low-power pick over the non-P version. Confirm your Flash and peripheral needs against the datasheet.

ATMEGA32U4-AU is a Microchip 8-bit AVR microcontroller with native USB in 44-pin TQFP — for USB HID devices: custom keyboards, dongles and game controllers. The on-chip USB device controller is the selection point: Arduino Leonardo-class USB without an external bridge. Selection advice: the AU suffix denotes TQFP-44 — the same chip as the Leonardo; for new USB designs, compare 32-bit USB MCUs (SAMD21, STM32F0) for more headroom, but the AVR toolchain and community remain the fastest path for simple HID. Microchip lists this part as In Production. Parameters verified against the Microchip official product page.

ATTINY85-20SU is a compact 8-bit AVR microcontroller from Microchip Technology in an 8-pin SOIC package — for small embedded functions like LED control, button handling and simple sensor interfaces. Five usable I/O pins in an 8-pin package is the selection point: the smallest practical microcontroller for glue-logic replacement and tiny control tasks. Selection advice: the 20SU suffix denotes the 20 MHz speed grade in SOIC-8 — the ATTINY85 also ships in PDIP-8, so match the full ATTINY85-20SU code to your layout. For new tiny designs, compare against newer ATTiny 0/1-series parts on peripherals; for existing builds, match the code exactly.

CY8C22545-24AXIT is an Infineon (Cypress) PSoC 1 8-bit programmable system-on-chip in 44-pin TQFP, tape and reel — 24 MHz M8C core, 16 KB flash, 1 KB RAM, 38 I/Os, three 10-bit ADCs and the original PSoC programmable analog and digital blocks. The programmable blocks are the selection point: comparators, filters, PWM and communication peripherals are configured in silicon instead of added as external parts, which is why this family still ships in legacy industrial, metering and consumer designs. Selection advice: this is PSoC 1 (8-bit M8C) — not PSoC 4/5LP (32-bit Arm); firmware and PSoC Creator projects do not transfer between generations. The AXIT code means 44-pin TQFP, industrial −40 °C to +85 °C, tape and reel; the tube version is CY8C22545-24AXI. For new designs needing CapSense or BLE, move to PSoC 4. Evidence: the Infineon CY8C22xxx datasheet ordering table and DigiKey listings confirm 16 KB/1 KB, 44-TQFP, −40 to +85 °C and Active status.

Megawin Technology MG82F6D64AD64 is a 64 Kbyte flash 8-bit MCU built on a high-performance 1T 8051 core running up to 36 MHz, in a 7x7 mm LQFP64 package. Its 1.8 V to 5.5 V wide operating range and -40 C to +105 C industrial temperature rating let one BOM cover both battery-powered and harsh-environment designs, cutting SKU count and qualification cost. The on-chip 12-bit ADC, dual UARTs, SPI, I2C, LIN and CRC16 engine plus Megawin proprietary on-chip-debug (OCD) interface shrink glue logic and speed up firmware bring-up, so small appliance, control and IoT teams reach production faster. Selection advice: the same MG82F6D64/32 family offers a 32 Kbyte variant and LQFP48/QFN48/LQFP32/QFN32 packages, so size the flash and pin count to your code and IO need rather than defaulting to the 64-pin part. Featured on hqew.com yesterday-hot list (2026-10-13). Parameters verified against Megawin Technology documentation.

PIC16F13276 is a Microchip Technology 8-bit PIC microcontroller with a Configurable Logic Block (CLB) — for timing-critical industrial, automotive and sensor-node designs that would otherwise need an MCU plus a separate CPLD or FPGA. The on-chip CLB is the selection point: 32 basic logic elements (each a 4-input look-up table plus flip-flop), auto-loaded at power-up or reset and running fully independent of the CPU, give deterministic, jitter-free hardware-logic response with no HDL toolchain. Around it sit up to 28 KB Flash, 2 KB SRAM, 256 bytes of data EEPROM, a 32 MHz clock, 1.8 V to 5.5 V operation, four Configurable Logic Cells, a 10-bit ADC with computation (up to 200 ksps), a 10-bit DAC, two 50 ns comparators, two 16-bit PWMs, two 16-bit plus two 8-bit timers, two EUSART modules (RS-232/RS-485/LIN), two MSSP modules (SPI/I2C, SMBus-compatible), Peripheral Pin Select, CRC with memory scan, and PDID, which permanently disables the programming and debug interface after deployment. It offers 36 I/O pins, industrial -40°C to +85°C and extended -40°C to +125°C grades, and 40-lead PDIP, 40-lead VQFN and 44-lead TQFP package options. Selection advice: choose PIC16F13276 when glue logic, PWM sequencing or sensor interfacing must stay deterministic under CPU load; pick the PIC16F13256 (28-pin, 25 I/O) when fewer pins suffice. Treat PDID as one-way: enable it only on production firmware you will never need to re-debug. Microchip documents this family in a preliminary datasheet, so confirm the exact ordering code and errata against the datasheet before committing a production BOM.

PIC16F877A-I/PT is an 8-bit PIC microcontroller from Microchip Technology in a 44-pin TQFP package, with integrated analog and serial peripherals — for embedded control, instrumentation and education. This is the classic teaching PIC: decades of textbooks, examples and programmer support make it the default for PIC-based learning and legacy industrial designs. Selection advice: the I/PT suffix denotes the industrial temperature grade in TQFP-44 — the PIC16F877A also ships in PDIP-40, so match the full PIC16F877A-I/PT code to your layout. For new designs, compare against newer PIC16F1xxx parts on peripherals and price; for existing builds and coursework, match the code exactly.

PIC18F4580-I/P is an 8-bit PIC18 microcontroller from Microchip Technology in a 40-pin PDIP package, with 32KB Flash, 1536 bytes RAM and 256 bytes EEPROM - for CAN-based embedded control: ECAN module with CAN 2.0B support, 11-channel 10-bit ADC, 36 I/O pins, 4 timers, dual comparators and EUSART, SPI and I2C, running up to 40 MHz at 4.2V to 5.5V across -40C to 85C. The integrated ECAN controller is the selection point: a full CAN node without an external CAN controller, plus nanoWatt power-managed modes that cut idle current in always-on industrial nodes. Business impact: one mature 5V part covers CAN networking, sensing and actuation, so legacy CAN designs keep a stable BOM with deep tooling and code support instead of requalifying a new MCU. Selection advice: the I/P code is the industrial-temperature PDIP-40 tube variant - for surface mount pick the I/PT TQFP-44 or I/ML QFN-44 codes; for a non-CAN design the PIC18F4520 is the cheaper sibling, and for 3.3V-only rails verify the supply against the 40 MHz requirement.
