Product details
Overview
SAF-XC164TM-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 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-16F20F BA datasheet, SAF-XC164TM-16F20F BA pinout, SAF-XC164TM-16F20F BA application, or SAF-XC164TM-16F20F BA equivalent, key selection criteria include Flash size (128 KB), RAM configuration (2 KB DPRAM / 4 KB DSRAM / 2 KB PSRAM), real-time peripheral set (GPT12E timer, RTC, watchdog), and 64-pin LQFP RoHS-compliant package.
Technical Context
The SAF-XC164TM-16F20F BA implements a 5-stage pipelined C166SV2 CPU with single-cycle 16×16 multiplication and MAC instructions, enabling deterministic real-time execution in motor control loops. Its interrupt system supports 63 sources across 16 priority levels with 50 ns sample rate, synchronized to peripheral events via the PEC for zero-latency I/O response.
On-chip clock generation uses a programmable PLL (1:0.15 to 1:10) or prescaler (1:1 to 60:1), allowing flexible system clock derivation from external crystals or oscillators. Memory subsystem includes linear 16 MB address space, dual-port RAM for concurrent CPU/peripheral access, and Flash with background erase/write capability.

FAQ
What is the maximum operating frequency of the SAF-XC164TM-16F20F BA?
The SAF-XC164TM-16F20F BA 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 external crystal input (e.g., 10 MHz crystal ×4 multiplier). The "20F" suffix denotes 20 MHz oscillator input capability, not CPU speed limit.
Does this microcontroller support JTAG-based debugging?
Yes, the SAF-XC164TM-16F20F BA includes full On-Chip Debug Support (OCDS) accessible via standard 5-pin JTAG interface (TCK, TMS, TDO, TDI, TRST). It supports real-time trace, hardware breakpoints, and register inspection without halting peripheral operation.
What are the Flash endurance and data retention specifications?
Infineon specifies 10,000 write/erase cycles minimum for the on-chip Flash memory and 20-year data retention at 85 °C. Flash sectors can be erased independently, and background programming allows code execution during write operations.
Is the SAF-XC164TM-16F20F BA qualified for automotive use?
No - the SAF-XC164TM-16F20F BA is rated for industrial temperature range (−40 to +85 °C) and lacks AEC-Q100 qualification. For automotive applications, Infineon recommends the SAF-XC164CS-16F40F (−40 to +125 °C) or XC2200 family derivatives with full automotive qualification.
