Product details
Overview
SAF-XC164KM-16F40F BA from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 128 KB on-chip Flash, 2 KB DPRAM + 4 KB DSRAM + 2 KB PSRAM, and dual CAN 2.0B interfaces (CAN0/CAN1) with 32 message objects. It operates at 40 MHz CPU clock (25 ns instruction cycle), supports JTAG-based on-chip debug (OCDS), and targets real-time embedded control in automotive powertrain and industrial motor drives.
For engineers reviewing the SAF-XC164KM-16F40F BA datasheet, SAF-XC164KM-16F40F BA pinout, SAF-XC164KM-16F40F BA application, or SAF-XC164KM-16F40F BA equivalent, key selection criteria include its 128 KB Flash capacity, dual CAN nodes with gateway functionality, 16-channel CAPCOM2 unit for PWM generation, and 64-pin LQFP RoHS-compliant package with 0.5 mm pitch.
Technical Context
The SAF-XC164KM-16F40F BA implements a 5-stage pipelined C166SV2 CPU core with single-cycle 16×16 multiplication, 21-cycle 32/16 division, and MAC instructions - enabling deterministic real-time control loops. Its interrupt system delivers 63 sources across 16 priority levels with 50 ns sample rate, coordinated via Peripheral Event Controller (PEC) for zero-latency peripheral-triggered DMA transfers.
On-chip peripherals include TwinCAN (Rev. 2.0B active) with full CAN and Basic CAN support on two independent nodes, plus ASC0/ASC1 (UART/SPI-like) and SSC0/SSC1 (high-speed synchronous serial) interfaces. Clock generation uses an integrated PLL configurable from 0.15× to 10× input frequency, supporting precise timing for motor commutation and CAN bit timing alignment.

The SAF-XC164KM-16F40F BA features a C166SV2 core rated for 40 MHz CPU clock operation, delivering a 25 ns instruction cycle time with single-cycle execution for most instructions. This frequency is achieved using the on-chip PLL driven by an external crystal (e.g., 8 MHz input ×5 = 40 MHz). The device supports static operation down to 0 Hz for low-power modes.
Does the SAF-XC164KM-16F40F BA support JTAG-based debugging out of the box?
Yes - the SAF-XC164KM-16F40F BA integrates On-Chip Debug Support (OCDS) accessible via standard JTAG pins (TCK, TDI, TDO, TMS, TRST). It supports full real-time debugging including breakpoints, watchpoints, register inspection, and flash programming without requiring external debug probes beyond a JTAG adapter compatible with Infineon DAS tools.
How many CAN nodes does the SAF-XC164KM-16F40F BA support, and what protocol versions are implemented?
The SAF-XC164KM-16F40F BA implements the TwinCAN module supporting two independent CAN nodes (CAN0 and CAN1), both compliant with ISO 11898-1:2003 (CAN 2.0B Active). Each node supports full CAN and Basic CAN message objects, with 32 total message objects shared across both controllers and gateway functionality for inter-node message forwarding.
What are the memory resources allocated to program and data storage in the SAF-XC164KM-16F40F BA?
The SAF-XC164KM-16F40F BA contains 128 KB of on-chip Flash for program storage, 2 KB of dual-port RAM (DPRAM) for CPU+DMA co-access, 4 KB of data SRAM (DSRAM), and 2 KB of program/data SRAM (PSRAM).
