Infineon Technologies XMC7100D-F100K4160AA

Overview

XMC7100D-F100K4160AA from Infineon is a 32-bit Arm® Cortex®-M7/M0+ dual-core microcontroller for industrial real-time control, featuring 4160 KB code-flash, 768 KB SRAM, and integrated CAN FD (up to 8 Mbps), 10/100 Mbps Ethernet MAC, and hardware security (eSHE/HSM, AES-256, SHA-512). It targets secure motor drives and industrial gateways requiring deterministic timing and FOTA-capable dual-bank flash.

For engineers reviewing the XMC7100D-F100K4160AA datasheet, XMC7100D-F100K4160AA pinout, XMC7100D-F100K4160AA application, or XMC7100D-F100K4160AA equivalent, key selection criteria include dual-core cache configuration (16 KB I/D TCM per M7 core), 220 GPIO count with HSIO support, RWW flash operation, IEEE-1588 PTP compliance, and safety features including SECDED ECC on SRAM/flash/TCM.

Technical Context

The device implements a heterogeneous dual-CPU subsystem: two 250-MHz Arm® Cortex®-M7 cores with independent 16-KB instruction/data caches and TCM, plus a dedicated 100-MHz Cortex®-M0+ for peripheral offload and secure boot execution. Inter-processor communication is handled via hardware mailbox and shared memory with SMPU protection.

Its peripheral architecture includes three DMA controllers (P-DMA0: 100 channels, P-DMA1: 58 channels, M-DMA0: 8 channels), runtime-reconfigurable SCBs (11 total, supporting UART/SPI/I²C), and TCPWM blocks (75×16-bit + 8×32-bit) with PWM_DT and quadrature decode modes for motor control.

FAQ

What is the maximum operating frequency of the Cortex®-M7 cores in XMC7100D-F100K4160AA?

The device contains two Arm® Cortex®-M7 CPUs each operating at up to 250 MHz, with independent 16-KB instruction and data caches and 16-KB TCM per core. This frequency is sustained under full thermal and voltage specifications (2.7–5.5 V supply, ambient ≤105°C) with all peripherals active and cache enabled.

Does XMC7100D-F100K4160AA support hardware-accelerated TLS 1.2/1.3?

Yes-the integrated Hardware Security Module (HSM) supports AES-128/192/256, SHA-256/512, and ECC key exchange (NIST P-256/P-384), enabling full TLS handshake acceleration. The HSM operates independently of the M7/M0+ cores and meets Common Criteria EAL4+ requirements for secure key storage and cryptographic isolation.

How many CAN FD channels are physically implemented in this specific variant?

XMC7100D-F100K4160AA implements eight fully independent CAN FD controllers, each with dedicated TX/RX pins and message RAM. All eight channels support ISO 11898-1:2015 compliance, up to 8 Mbps data rate, and flexible bit timing configuration-including separate arbitration and data phase settings.

Is external SDRAM required to use the Ethernet MAC interface?

No-Ethernet MAC operation does not require external SDRAM. The internal 768 KB SRAM provides sufficient buffer space for standard Ethernet frame buffering (including jumbo frames up to 9000 bytes). External memory interface (SPI/HYPERBUS™) is optional and used only for extended code/data storage or XIP execution.
