Infineon Technologies SAF-XC164GM-8F40F AA

Overview

SAF-XC164GM-8F40F AA from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, operating at 40 MHz with 64 KB on-chip Flash, 2 KB DPRAM, and integrated TwinCAN 2.0B interface. It features a 5-stage pipeline CPU, 14-channel 10-bit ADC (2.55 µs conversion), and 16-channel CAPCOM2 unit. Used in industrial motor control systems requiring deterministic real-time response and dual-CAN bus coordination.

For engineers reviewing the SAF-XC164GM-8F40F AA datasheet, SAF-XC164GM-8F40F AA pinout, SAF-XC164GM-8F40F AA application, or SAF-XC164GM-8F40F AA equivalent, key selection criteria include CAN 2.0B dual-node support, 40 MHz real-time execution timing, Flash endurance (10k write/erase cycles), and LQFP-64 RoHS-compliant packaging for high-density PCB layouts.

Technical Context

The XC164GM implements a C166SV2 CPU core with 5-stage pipelining, enabling single-cycle instruction execution at 40 MHz (25 ns cycle time) and 1-cycle 16×16 multiplication. Its interrupt system supports 63 sources across 16 priority levels with 50 ns sample rate, critical for time-critical motor commutation events.

On-chip peripherals include two ASC/USART interfaces, two SSC channels, a 5-timer GPT12E unit, and a TwinCAN module with 32 message objects distributed across two independent CAN nodes-supporting gateway functionality between CAN buses without external arbitration logic.

FAQ

What is the maximum operating temperature range for SAF-XC164GM-8F40F AA?

The SAF-XC164GM-8F40F AA is rated for operation from −40 °C to +85 °C ambient temperature, validated per Infineon's industrial qualification standards. This range covers under-hood automotive locations and industrial enclosures without forced cooling, and thermal derating is not required up to 85 °C case temperature under specified airflow conditions.

Does this microcontroller support CAN FD or only classical CAN?

The SAF-XC164GM-8F40F AA implements TwinCAN Rev. 2.0B only, supporting classical CAN with bit rates up to 1 Mbps and 32 message objects across two independent nodes. It does not support CAN FD frame format, payload extension, or variable bit rate switching. CAN FD capability requires newer derivatives such as the XC2267 or AURIX™ family.

How many clock sources does the device support, and can it run without an external crystal?

The device supports three clock sources: external crystal/resonator (via XTAL1/XTAL2), external clock input (EXTCLK), and internal RC oscillator (for reset/startup only). The PLL requires an external source; it cannot generate 40 MHz from the internal RC alone. However, the internal oscillator enables boot and debug initialization before external clock stabilization.

Is the on-chip Flash memory capable of EEPROM emulation, and what is its endurance rating?

Yes, the 64 KB Flash supports EEPROM emulation using Infineon's Flash API library, with guaranteed endurance of 10,000 write/erase cycles per sector and data retention of 20 years at 85 °C. Emulation relies on wear-leveling across designated sectors and requires application-level management of logical address mapping.
