Product details
Overview
SAF-XC164SM-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 operation up to 40 MHz CPU clock (25 ns instruction cycle). It integrates dual ASC/SSC serial interfaces, a 14-channel 10-bit ADC (2.55 µs conversion), CAPCOM2/CAPCOM6 PWM units, and GPT12E timer for motor control and industrial automation.
For engineers reviewing the SAF-XC164SM-16F40F BA datasheet, SAF-XC164SM-16F40F BA pinout, SAF-XC164SM-16F40F BA application, or SAF-XC164SM-16F40F BA equivalent, key selection criteria include Flash size, SRAM partitioning (DPRAM/DSRAM/PSRAM), real-time peripheral event controller (PEC) support, PLL-based clock generation (1:0.15–1:10), and RoHS-compliant 64-pin LQFP package with 0.5 mm pitch.
Technical Context
The XC164SM implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and 21-cycle 32/16 divide - enabling deterministic real-time execution in embedded control loops. Its memory subsystem supports linear 16 MB address space with separate code/data SRAM banks and dual-port RAM for concurrent CPU/peripheral access.
Peripheral integration centers on time-critical control: CAPCOM6 provides flexible PWM with dead-time insertion and fault protection; GPT12E offers five independent timers with capture/compare and reload capabilities; PEC enables single-cycle DMA transfers across full 24-bit address space without CPU intervention.

| GPT12E Timer | 5 independent 16-bit timers with reload, capture, compare, and PWM output modes - supports multi-axis motion control timing with sub-microsecond jitter |
| Real-Time Clock (RTC) | On-chip RTC driven by main oscillator with calendar function (year/month/day/hour/min/sec) - enables time-stamped logging without external components |
| Power Management Modes | Idle, Sleep, and Power Down modes with selective peripheral clock gating - reduces active current to 12 mA at 40 MHz and standby current to 20 µA |
