Infineon Technologies XMC4500F100F768ACXQMA1

Overview

XMC4500F100F768ACXQMA1 from Infineon Technologies is a 32-bit ARM Cortex-M4 microcontroller with 768 KB on-chip Flash, 192 KB SRAM (64 KB DSRAM1 + 64 KB DSRAM2 + 32 KB DSRAM3), 100-pin LQFP package, and industrial temperature range (–40°C to +105°C). It integrates Ethernet MAC, USB 2.0 Full-Speed OTG with PHY, MultiCAN (3 nodes, 1 Mbit/s), six USIC channels, four 12-bit VADCs (8-channel each), two 12-bit DACs, CCU4/CCU8 timers for motor control, and LEDTS for HMI - deployed in industrial PLCs, servo drives, and power converters.

For engineers reviewing the XMC4500F100F768ACXQMA1 datasheet, XMC4500F100F768ACXQMA1 pinout, XMC4500F100F768ACXQMA1 application, or XMC4500F100F768ACXQMA1 equivalent, key selection criteria include Flash/SRAM sizing, Ethernet+USB+CAN co-integration, real-time peripheral latency (e.g., CCU8 dead-time control), analog subsystem resolution (VADC/DAC), and industrial-grade thermal operation up to +105°C.

Technical Context

The XMC4500F100F768ACXQMA1 implements a tightly coupled ARM Cortex-M4 core with hardware FPU and MPU, supporting deterministic real-time execution for closed-loop control. Its bus matrix enables concurrent access to Flash, SRAM, and peripherals without arbitration stalls - critical for time-sensitive motor control and sensor fusion.

It features dual-domain clocking: a PLL-based system clock up to 144 MHz feeds CPU and high-speed peripherals (Ethernet, USB, USIC), while independent low-jitter clock sources drive analog blocks (VADC, DAC) and timing-critical modules (CCU8, POSIF), ensuring signal integrity in mixed-signal industrial environments.

FAQ

Does XMC4500F100F768ACXQMA1 support JTAG debugging?

Yes - it fully supports ARM-standard JTAG (IEEE 1149.1) with boundary scan, 8 hardware breakpoints, and CoreSight debug infrastructure. The LQFP-100 package exposes TCK, TMS, TDI, TDO, and TRST pins on dedicated pins (P1.0–P1.4), enabling connection to standard debug probes like Segger J-Link or ST-LINK v2.

What is the maximum operating frequency of the CPU core?

The ARM Cortex-M4 core operates at up to 144 MHz, achieved via an internal PLL fed by either the internal 10 MHz RC oscillator or an external crystal (1–25 MHz). System performance is validated across the full –40°C to +105°C range with 1.3 V core supply, meeting all AC timing specifications in the datasheet.

Can the USB interface operate in host mode?

Yes - the integrated USB 2.0 Full-Speed OTG module supports both host and device roles. In host mode, it enumerates standard class devices (e.g., HID keyboards, mass storage) using the on-chip PHY and internal transceiver; no external components are required beyond a USB connector and ESD protection diode.

Is there hardware support for functional safety standards?

Yes - the device includes ECC on all SRAM banks, lockstep-capable watchdog (WDT), redundant clock monitoring, and memory protection unit (MPU) - enabling compliance with IEC 61508 SIL2 and ISO 13849 PLd. Safety manuals and FMEDA reports are available from Infineon upon NDA.
