Infineon Technologies XMC4700F100K1536AAXQMA1

Overview

XMC4700F100K1536AAXQMA1 from Infineon Technologies is an ARM® Cortex®-M4 32-bit microcontroller with 2 MB on-chip Flash, 256 KB SRAM (96 KB DSRAM + 128 KB CCM), and 100-pin LQFP package. It integrates Ethernet MAC, EtherCAT Slave, USB OTG Full-Speed PHY, six USIC channels, four 12-bit VADCs (8-channel each), two 12-bit DACs, CCU8/CCU4 timers, and POSIF for servo control - deployed in industrial motor drives and PLC I/O modules.

For engineers reviewing the XMC4700F100K1536AAXQMA1 datasheet, XMC4700F100K1536AAXQMA1 pinout, XMC4700F100K1536AAXQMA1 application, or XMC4700F100K1536AAXQMA1 equivalent, key selection criteria include EtherCAT timing compliance (64-bit distributed clock sync), EBU SDRAM interface support, and dual 12-bit DAC channel resolution for analog feedback loops in closed-loop power conversion systems.

Technical Context

The device implements a tightly coupled memory subsystem with separate instruction (ICode) and data (DCode) buses, enabling concurrent CPU fetch and peripheral access. Its system architecture includes two General Purpose DMA controllers (GPDMA0/GPDMA1), an Event Request Unit (ERU) for asynchronous event routing, and a Flexible CRC Engine (FCE) supporting multiple polynomial configurations for communication integrity.

Real-time control is enabled by dual CCU8 units with dead-time insertion, programmable shadow transfer, and synchronized PWM outputs - paired with POSIF for quadrature encoder and Hall sensor interfacing. The VADC subsystem supports simultaneous sampling across four converters with hardware-triggered sequence control and out-of-range detection per channel.

FAQ

Does XMC4700F100K1536AAXQMA1 support JTAG debugging?

Yes, it supports IEEE 1149.1-compliant JTAG debugging via dedicated TCK/TMS/TDI/TDO pins and SWD (Serial Wire Debug) through SWDIO/SWCLK. The debug interface enables full core visibility, flash programming, and real-time trace using the Embedded Trace Macrocell (ETM), with no external debug probe required beyond standard ARM-compliant tools 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 under specified conditions (VDD = 3.3 V, TA = –40 °C to 125 °C). This frequency is achieved using the internal PLL with input from either the internal RC oscillator (10 MHz) or an external crystal (1–20 MHz), and is validated across all speed grades in the XMC4700 series datasheet Section 3.3.4.

Can the USB OTG interface operate in host mode?

No - the USB interface is strictly Full-Speed OTG (On-The-Go) with integrated PHY, but only supports device mode and limited host capability via external VBUS detection and ID pin sensing. Host functionality is restricted to enumeration of USB mass storage devices (e.g., firmware update sticks); it lacks full host stack hardware acceleration and does not support HID or CDC classes in host role.

Is there hardware support for functional safety standards?

Yes - the device includes safety mechanisms such as lockstep-capable watchdog timers (WDT), memory parity/ECC on critical RAM blocks, CPU lockstep monitor (in select variants), and diagnostic libraries certified to IEC 61508 SIL2. These features are documented in the XMC4700 Safety Manual (Infineon Doc ID: SLXMC4700), and supported by SafeAssure qualification evidence.
