Product details
Overview
SAF-XC164TM-8F20F AA from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 64 KB on-chip Flash, 2 KB DPRAM + 2 KB DSRAM + 2 KB PSRAM, and operation at 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 capture/compare unit. Used in industrial motor control and embedded power conversion systems.
For engineers reviewing the SAF-XC164TM-8F20F AA datasheet, SAF-XC164TM-8F20F AA pinout, SAF-XC164TM-8F20F AA application, or SAF-XC164TM-8F20F AA equivalent, key selection criteria include Flash size (64 KB), RAM configuration (2 KB DPRAM / 2 KB DSRAM / 2 KB PSRAM), real-time peripheral set (GPT12E, RTC, watchdog), and 64-pin TQFP RoHS-compliant packaging.
Technical Context
The SAF-XC164TM-8F20F AA implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and 21-cycle 32/16 divide. Its interrupt system supports 63 sources across 16 priority levels with 50 ns sample rate and PEC-driven DMA using 24-bit pointers.
On-chip peripherals include a 14-channel ADC with programmable resolution (8/10-bit) and conversion time (2.15–2.55 µs), dual ASC interfaces with LIN support, dual SSC modules for SPI-like high-speed transfers, and a real-time clock driven by the main oscillator - all coordinated via a centralized peripheral event controller.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-8F40F | Same C166SV2 core, 64 KB Flash, but higher max CPU clock (40 MHz vs. 20 MHz), different derivative step (BA vs. AA) | Targeted at higher-performance motor control where faster loop rates are required | Select if design requires >20 MHz sustained CPU throughput or newer mask revision reliability |
| SAF-XC167CI-16F40F | Enhanced C166SV2+ core, 128 KB Flash, 8 KB RAM, added CAN 2.0B controller and larger CAPCOM2 | Required where CAN bus integration, larger code space, or extended timer resources are mandatory | Choose when CAN communication or >64 KB firmware footprint is essential |
Compared with SAF-XC164TM-8F20F AA, the XC164CS-8F40F offers higher clock headroom for algorithm scaling, while the XC167CI-16F40F adds CAN and memory - making the TM variant optimal for cost-constrained, non-CAN industrial control where 20 MHz CPU and 64 KB Flash suffice.

FAQ
What is the maximum operating frequency of the SAF-XC164TM-8F20F AA?
The SAF-XC164TM-8F20F AA operates at a maximum CPU clock frequency of 40 MHz, delivering a 25 ns instruction cycle time. This is achieved using the on-chip PLL with programmable multiplication factors (1:0.15 to 1:10) or an external clock source. The "20F" in the part number denotes a 20 MHz oscillator input rating, but the internal PLL allows doubling to 40 MHz for full performance.
Does the SAF-XC164TM-8F20F AA support in-system programming (ISP)?
Yes - it features an on-chip bootstrap loader accessible via ASC0, enabling in-system programming of Flash memory without external programming hardware. The bootloader supports UART-based firmware updates and is protected by user-configurable lock bits to prevent unauthorized reprogramming.
How many analog input channels does the integrated ADC support?
The SAF-XC164TM-8F20F AA integrates a 14-channel, 10-bit successive-approximation ADC with programmable resolution (8-bit or 10-bit) and conversion times as low as 2.15 µs (8-bit) or 2.55 µs (10-bit). All channels share a common sample-and-hold circuit and support both single-shot and continuous scan modes.
Is JTAG debugging supported, and what capabilities does it provide?
Yes - the device includes full On-Chip Debug Support (OCDS) via IEEE 1149.1-compliant JTAG (TCK/TDI/TDO/TMS/TRST). This enables non-intrusive breakpoints, real-time register/memory inspection, and flash programming during development - all without consuming CPU cycles or requiring dedicated debug ROM space.
