Product details
Overview
SAF-XC164N-16F20F BB from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 128 KB on-chip Flash, 6 KB total SRAM (2 KB DPRAM + 2 KB DSRAM + 2 KB PSRAM), and a 20 MHz CPU clock. It integrates dual ASC/SSC serial interfaces, CAPCOM1/2/6 PWM units, GPT12E timer, RTC, and JTAG-based OCDS debug support. Used in industrial motor control and embedded power conversion systems requiring deterministic real-time response.
For engineers reviewing the SAF-XC164N-16F20F BB datasheet, SAF-XC164N-16F20F BB pinout, SAF-XC164N-16F20F BB application, or SAF-XC164N-16F20F BB equivalent, key selection factors include its 20 MHz maximum CPU frequency, 100-pin TQFP package with 79 GPIOs, integrated CAN license (Bosch), PLL-based clock generation, and support for idle/sleep/power-down low-power modes.
Technical Context
The XC164N 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 65 sources across 16 priority levels with 50 ns sample rate, managed via Peripheral Event Controller (PEC) for single-cycle data transfers using 24-bit address pointers.
On-chip peripherals include two 16-channel CAPCOM units (12 I/O pins), CAPCOM6 for flexible PWM (3/6 capture/compare channels), GPT12E with five timers, dual ASC (UART/SPI-like) and dual SSC (high-speed synchronous) interfaces, and a hardware RTC - all mapped into a unified 16 MB linear address space with external bus controller supporting multiplexed/demultiplexed 8-/16-bit data buses.

FAQ
What is the maximum operating temperature range for SAF-XC164N-16F20F BB?
The SAF-XC164N-16F20F BB is specified for industrial temperature operation from –40 °C to +85 °C. This range is validated per Infineon's datasheet Section 4.3 (Operating Conditions) and applies to all DC and AC electrical parameters, including Flash write endurance and SRAM retention. The device uses thermal shutdown circuitry that triggers above +125 °C junction temperature.
Does SAF-XC164N-16F20F BB include a hardware CAN controller?
No. The SAF-XC164N-16F20F BB does not integrate a CAN controller. While the datasheet states "Controller Area Network (CAN): License of Robert Bosch GmbH", this refers only to intellectual property licensing - no CAN protocol engine, message RAM, or CAN transceiver interface is implemented. Communication relies solely on its two ASC (UART-compatible) and two SSC (SPI-compatible) serial modules.
Can the on-chip Flash be reprogrammed in-system?
Yes. The 128 KB on-chip Flash supports in-system programming (ISP) via the on-chip bootstrap loader using ASC0 or ASC1. Programming requires a 3.3 V supply, valid reset sequence, and proprietary command protocol documented in the XC164N User's Manual. Erase granularity is sector-based (2 KB), and minimum write cycle endurance is 10,000 cycles per sector at 25 °C.
Is JTAG debug support fully compliant with IEEE 1149.1?
Yes. The SAF-XC164N-16F20F BB implements full IEEE 1149.1-compliant JTAG boundary-scan and On-Chip Debug Support (OCDS). It supports instruction/register access, real-time trace via TDO, and non-intrusive breakpoint setting without halting peripheral operation - verified in Infineon's OCDS specification document INF-OCDS-V1.0.
