Product details
Overview
SAF-XC164SM-16F20F 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 real-time clock - deployed in industrial motor control and embedded power conversion systems.
For engineers reviewing the SAF-XC164SM-16F20F BA datasheet, SAF-XC164SM-16F20F BA pinout, SAF-XC164SM-16F20F BA application, or SAF-XC164SM-16F20F BA equivalent, key selection criteria include Flash size (128 KB), RAM configuration (2K/4K/2K split), 64-pin LQFP package, 40 MHz timing capability, and integrated peripheral set for deterministic real-time control.
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 execution in time-critical control loops. Its interrupt system supports 63 sources across 16 priority levels with 50 ns sample rate, coordinated via Peripheral Event Controller (PEC) for single-cycle data transfers using 24-bit address pointers.
On-chip peripherals include two independent ASC (asynchronous/synchronous UART) and two SSC (high-speed synchronous SPI-like) interfaces, CAPCOM6 for flexible PWM generation with dead-time insertion, and GPT12E timer unit with five independent timers - all synchronized to a PLL-driven clock system configurable from 1:0.15 to 1:10 multiplication ratio.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C166SV2 16-bit pipelined core with 5-stage pipeline, zero-cycle jump, and 1-cycle MAC - enables tight control loop timing in motor drive firmware. |
| Max CPU Clock | 40 MHz (25 ns instruction cycle) - supports real-time response ≤1 µs for critical ISR execution in industrial automation. |
| Flash Memory | 128 KB on-chip Flash - sufficient for complex field-oriented control (FOC) algorithms plus bootloader and safety monitoring code. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-16F40F BA | Same C166SV2 core, identical Flash/RAM, but includes CAN 2.0B controller and enhanced ESD protection on I/O pins. | Required where CAN bus integration is mandatory (e.g., automotive body control modules). | Select only if CAN protocol stack and physical layer support are needed - no benefit for pure ASC/SSC-based industrial networks. |
| SAF-XC2267M-104F80L AA | Successor 32-bit TriCore™ core, 80 MHz, 512 KB Flash, 64 KB RAM, but larger 100-pin LQFP package and higher power consumption. | Suitable for next-generation designs requiring floating-point math, safety certification (ISO 26262 ASIL-B), or multi-axis coordination. | Choose for scalability path beyond 16-bit limits - not drop-in compatible due to pinout, toolchain, and peripheral register differences. |
