Product details
Overview
SAF-XC164TM-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 at up to 40 MHz CPU clock (25 ns instruction cycle). It integrates ASC0/ASC1 USARTs, SSC0/SSC1 synchronous serial channels, a 14-channel 10-bit ADC (2.55 µs conversion), and CAPCOM2 for motor control timing. Used in industrial motor drives requiring deterministic real-time PWM and analog feedback.
For engineers reviewing the SAF-XC164TM-16F40F BA datasheet, SAF-XC164TM-16F40F BA pinout, SAF-XC164TM-16F40F BA application, or SAF-XC164TM-16F40F BA equivalent, key selection criteria include Flash size (128 KB), RAM configuration (2+4+2 KB), 40 MHz performance envelope, integrated CAPCOM2 for 16-channel capture/compare, and dual USART + dual SSC interfaces for multi-protocol communication in embedded motion control systems.
Technical Context
The SAF-XC164TM-16F40F BA 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 motor control loops. Its peripheral event controller (PEC) supports single-cycle data transfers across the full 16 MB address space using 24-bit pointers.
On-chip clock generation includes a programmable PLL (1:0.15 to 1:10) and prescaler (1:1 to 60:1), allowing precise system clock derivation from external crystals or oscillators. The device supports three low-power modes (Idle, Sleep, Power Down) with configurable wake-up sources including timer, interrupt, and peripheral events.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time?
The SAF-XC164TM-16F40F BA operates at a maximum CPU clock of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution of most instructions. This timing is guaranteed across the full -40°C to +85°C temperature range and 4.5–5.5 V supply voltage, enabling sub-microsecond control loop execution in motor applications.
Does this microcontroller support in-system programming (ISP) via serial interface?
Yes - the SAF-XC164TM-16F40F BA includes an on-chip bootstrap loader accessible via ASC0, allowing firmware updates without external programming hardware. The bootloader supports standard UART protocols and verifies Flash integrity after each write, ensuring reliable field upgrades in deployed equipment.
How many independent PWM channels can be generated using CAPCOM2?
The CAPCOM2 unit provides 16 independent capture/compare channels, each configurable as a PWM output with programmable period, duty cycle, and polarity. All channels share a common time base but support individual dead-time insertion - enabling full 3-phase inverter control (6 PWMs) plus auxiliary timing signals.
Is JTAG debug support fully implemented on this derivative?
Yes - the SAF-XC164TM-16F40F BA implements full On-Chip Debug Support (OCDS) via IEEE 1149.1 JTAG, including real-time trace, hardware breakpoints, watchpoints, and register visibility. This enables non-intrusive debugging of time-critical ISR routines and memory-mapped peripheral interactions during motor control development.
