XMC5100-F100K576AAInfineon Technologies32-bit microcontroller · LQFP-100XMC5100-F100K576AA is a dual-core industrial microcontroller from Infineon Technologies, combining an 80 MHz Arm Cortex-M4F main core with an 80 MHz Arm Cortex-M0+ core dedicated to cryptography, with 576 KB code flash, 64 KB work flash and 64 KB SRAM in a 100-pin LQFP package. The dual-core split is the practical benefit: real-time control runs on the M4F while security and crypto tasks stay on the M0+, and up to 4 CAN FD channels, 6 configurable serial communication blocks (I2C, SPI or UART each), 32 ADC channels and timer/PWM blocks cover motor control, HVAC and lighting designs without external glue logic. For procurement, the payoff is family scalability: the XMC5000 series shares the ModusToolbox toolchain and a migration path to XMC7000, so firmware and tooling investment carries across cost, mid-range and high-end variants, and the 2.7 V to 5.5 V supply range plus -40 °C to +125 °C operation suit both 3.3 V and 5 V industrial systems. Evidence: Infineon datasheet 002-41593 Rev. *A defines this ordering code and its memory and peripheral configuration. Selection and procurement advice: within the family, the XMC5100 is the cost-sensitive pick; choose the XMC5200 for 160 MHz operation with larger memory and more CAN FD channels, or the XMC5300 for gateway-class designs; the F100 code denotes the 100-pin LQFP package, so match the full XMC5100-F100K576AA code to your layout, since the same series also ships in a 64-pin package.
