Infineon Technologies XMC7100D-F100K2112AA

Overview

XMC7100D-F100K2112AA from Infineon is a 32-bit Arm® Cortex®-M7/M0+ dual-core microcontroller for industrial real-time control, featuring 250-MHz M7 CPU, 100-MHz M0+ co-processor, 4160 KB code-flash, 768 KB SRAM, and integrated CAN FD (up to 8 Mbps) and 10/100 Mbps Ethernet MAC. It supports secure boot via eSHE/HSM, IEEE-1588 PTP, and motor-control-optimized ADCs with synchronized 12-bit sampling at 1 Msps.

For engineers reviewing the XMC7100D-F100K2112AA datasheet, XMC7100D-F100K2112AA pinout, XMC7100D-F100K2112AA application, or XMC7100D-F100K2112AA equivalent, key selection criteria include dual-core deterministic latency, FOTA-capable dual-bank flash, hardware-accelerated crypto (AES-256, ECC, SHA-512), and 220 GPIO with Smart I/O Boolean logic offload.

Technical Context

The device implements a heterogeneous dual-CPU architecture: primary M7 cores handle high-throughput control loops and protocol stacks (CAN FD/Ethernet), while the M0+ manages peripheral arbitration, security services, and low-latency I/O response. Hardware inter-processor communication (IPC) and three DMA controllers (100/58/8 channels) enable zero-copy data movement between subsystems.

Clocking is managed by multiple oscillators (IMO, ILO, ECO, WCO), dual PLL/FLL, and safety-critical clock supervision (CSV). Memory subsystem includes SECDED ECC on all SRAM, TCM, and flash, plus RWW capability enabling concurrent execution and firmware update in dual-bank mode.

Key Specifications

Pinout & Package

This device is packaged in a 100-pin TEQFP (14 × 14 × 1.6 mm, 0.5-mm pitch) with exposed thermal pad. Pin functions are defined across five voltage domains (VDDD, VDDA, VCCD, VCCIO, VSS) and include dedicated power, ground, clock, reset, debug (SWD/JTAG), CAN FD transceiver pins (CAN0–CAN7), Ethernet PHY signals (TXD/RXD, CRS/CLK), and 220 programmable I/Os with GPIO_STD/ENH/HSIO_STD types.

FAQ

What is the maximum operating frequency of the Cortex-M7 core in XMC7100D-F100K2112AA?

The Arm® Cortex®-M7 core operates at up to 250 MHz, verified under full industrial temperature range (–40°C to +105°C) and 2.7–5.5 V supply. This frequency is sustained with active cache and TCM usage, and is supported by the on-chip PLL with jitter <±50 ppm, enabling cycle-accurate timing for motor control PWM and Ethernet packet processing.

Does XMC7100D-F100K2112AA support IEEE-1588 Precision Time Protocol?

Yes, the integrated 10/100 Mbps Ethernet MAC fully supports IEEE-1588-2008 (PTPv2) with hardware timestamping accuracy of ±50 ns. It includes dedicated PTP registers, event message filtering, and transparent clock functionality - required for time-synchronized industrial automation and AVB audio/video networks.

How many CAN FD channels does this MCU support, and what is the maximum data rate?

XMC7100D-F100K2112AA supports up to eight CAN FD channels, each capable of data rates up to 8 Mbps in FD mode (per ISO 11898-1:2015). Physical layer limitations apply based on transceiver and bus topology, but the controller itself handles bit-rate switching, CRC-21 calculation, and payload lengths up to 64 bytes.

Is external memory encryption supported, and how is it implemented?

Yes, the MCU supports on-the-fly encryption and decryption for external memory accessed via SPI or HyperBus™ interfaces. Encryption uses AES-128 in XTS mode, with keys stored exclusively in the HSM's secure memory. The feature enables Execute-in-Place (XIP) from encrypted external flash while preventing firmware extraction via physical memory probing.
