Infineon Technologies XMC7100-E272K4160AA

Overview

XMC7100-E272K4160AA from Infineon is a 32-bit Arm® Cortex®-M7/M0+ dual-core microcontroller with 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, ECC, SHA-512). It targets industrial real-time control systems requiring functional safety, secure boot, and deterministic I/O timing.

For engineers reviewing the XMC7100-E272K4160AA datasheet, XMC7100-E272K4160AA pinout, XMC7100-E272K4160AA application, or XMC7100-E272K4160AA equivalent, this device supports FOTA updates via dual-bank flash, synchronized multi-ADC sampling for motor control, and IEEE-1588 PTP time synchronization in industrial Ethernet nodes.

Technical Context

The XMC7100-E272K4160AA implements a heterogeneous dual-CPU architecture: one 250-MHz Cortex-M7 core with 16-KB I/D cache and TCM, plus a dedicated 100-MHz Cortex-M0+ for peripheral offload and security services. Inter-processor communication is handled by hardware mailbox and shared memory with SMPU protection.

Its peripheral subsystem includes eight CAN FD controllers compliant with ISO 11898-1:2015 and Bosch CAN FD v1.0, an IEEE-802.3bw-compliant Ethernet MAC supporting MII/RMII PHY interfaces and IEEE-1588 PTP timestamping, and three SAR ADCs (12-bit, 1 Msps) with synchronized sampling across all channels for motor current sensing.

FAQ

What is the maximum operating frequency of the Cortex-M7 core in the XMC7100-E272K4160AA?

The primary Cortex-M7 core operates at up to 250 MHz, verified under worst-case voltage (2.7 V) and temperature (105°C) conditions per Infineon's DC/AC electrical specifications. This frequency is sustained using the internal PLL with ECO or IMO clock sources, and includes full cache and TCM enablement for deterministic real-time execution.

Does the XMC7100-E272K4160AA support secure boot with public-key verification?

Yes-it implements fast secure boot using digital signature verification with ECDSA (P-256) or RSA-2048, enforced by the hardware security module (HSM) running on the isolated Cortex-M0+ core. The root-of-trust is stored in immutable one-time-programmable (OTP) memory, and signature checks occur before any M7 code execution begins.

How many CAN FD channels are physically implemented, and what transceivers are compatible?

The device integrates eight fully independent CAN FD controllers. Each requires an external CAN FD transceiver; Infineon recommends the TJA1145 or TJA146x series for ISO 11898-2 compliance and robust EMC performance. All eight channels support concurrent operation at up to 8 Mbps nominal bit rate, subject to physical layer limitations.

Is the Ethernet MAC capable of IEEE-1588 Precision Time Protocol hardware timestamping?

Yes-the integrated 10/100 Mbps Ethernet MAC includes dedicated hardware timestamping logic compliant with IEEE-1588-2008 (PTPv2), enabling sub-microsecond timestamp insertion on ingress/egress frames. Timestamps are captured at the MAC-PHY boundary and accessible via dedicated registers for synchronization in industrial motion control networks.
