Product details
Overview
XC164CS32F40FBBAKXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 256 KB on-chip Flash, 12 KB total SRAM (2 KB DPRAM + 4 KB DSRAM + 6 KB PSRAM), and integrated TwinCAN 2.0B interface with 32 message objects across two CAN nodes. It operates from -40 °C to 125 °C, supports 40 MHz CPU clock (25 ns instruction cycle), and targets automotive powertrain and industrial motor control applications.
For engineers reviewing the XC164CS32F40FBBAKXUMA1 datasheet, XC164CS32F40FBBAKXUMA1 pinout, XC164CS32F40FBBAKXUMA1 application, or XC164CS32F40FBBAKXUMA1 equivalent, key selection criteria include its dual-CAN node capability, 14-channel 10-bit ADC with 2.55 µs conversion time, CAPCOM6 PWM unit, GPT12E timer subsystem, and JTAG-based on-chip debug support (OCDS).
Technical Context
The XC164CS32F40FBBAKXUMA1 implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiplication, and MAC instructions-enabling deterministic real-time execution in safety-critical embedded systems. Its memory architecture includes separate 16 MB linear address spaces for code and data, with programmable external bus timing supporting multiplexed/demultiplexed 8-/16-bit interfaces.
Peripheral integration centers on deterministic I/O control: twin ASC/SSC serial channels, a 5-timer GPT12E unit, real-time clock, and a dedicated CAPCOM6 module offering 3/6 capture/compare channels plus 1 compare-only channel for flexible PWM generation in motor gate drive applications.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time of the XC164CS32F40FBBAKXUMA1?
The XC164CS32F40FBBAKXUMA1 achieves a maximum CPU clock frequency of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution. This performance is enabled by its 5-stage pipelined C166SV2 core and on-chip PLL, which supports clock scaling factors from 1:0.15 to 1:10 relative to the external crystal input.
Does the XC164CS32F40FBBAKXUMA1 support CAN FD or only classical CAN?
The XC164CS32F40FBBAKXUMA1 implements TwinCAN Revision 2.0B, supporting only classical CAN (up to 1 Mbps) with full CAN and basic CAN modes. It does not support CAN FD features such as flexible data-rate or extended data length. For CAN FD capability, Infineon's XC2267 or XMC4000 families are required.
How is Flash memory programmed and verified on this microcontroller?
Flash programming is performed via the on-chip bootstrap loader using ASC0 serial interface, or through JTAG using Infineon's DAS tools. Verification is supported by hardware checksum calculation (CRC16) and read-after-write validation. The Flash module supports 100,000 write/erase cycles and data retention of 20 years at 125 °C.
What debug capabilities does the XC164CS32F40FBBAKXUMA1 provide during development?
The device integrates On-Chip Debug Support (OCDS) accessible via standard JTAG interface, enabling non-intrusive breakpoints, real-time trace, register and memory inspection, and flash programming. OCDS operates independently of CPU execution state, allowing full visibility into interrupt latency, peripheral register updates, and stack usage during real-time operation.
