Product details
Overview
SAF-XC164KM-8F40F 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 integrated TwinCAN 2.0B interface with dual CAN nodes. It operates at up to 40 MHz CPU clock (25 ns instruction cycle), supports 16-priority-level interrupts with 50 ns sample rate, and targets real-time motor control and industrial automation systems.
For engineers reviewing the SAF-XC164KM-8F40F AA datasheet, SAF-XC164KM-8F40F AA pinout, SAF-XC164KM-8F40F AA application, or SAF-XC164KM-8F40F AA equivalent, key selection criteria include Flash size (64 KB), dual-CAN node support, 40 MHz timing performance, SRAM partitioning (DPRAM/DSRAM/PSRAM), and LQFP-64 RoHS-compliant packaging.
Technical Context
The XC164KM implements a 5-stage pipelined C166SV2 CPU core with single-cycle 16×16 multiply, 21-cycle 32/16 divide, and MAC instructions. Its interrupt system delivers 50 ns minimum sample rate across 63 sources with 16 priority levels and hardware-assisted context switching via two local register banks.
On-chip peripherals include a 16-channel CAPCOM2 unit, GPT12E timer with five independent timers, two ASC (UART) and two SSC (SPI-like) serial interfaces, and a TwinCAN module supporting 32 message objects, full CAN/BASIC CAN, and gateway functionality across two physical CAN nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive/industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CM-8F40F | Same core and peripherals but lacks TwinCAN; only single CAN node (CAN0) implemented | Suitable for cost-sensitive CAN-only systems without gateway or dual-bus requirements | Select when dual-CAN functionality is unnecessary and BOM cost reduction is critical |
| SAF-XC2267-104F80L | Enhanced C166SV2 derivative with 128 KB Flash, 8 KB RAM, and additional ASC/SSC channels | Targets higher-complexity applications requiring larger code footprint and expanded serial connectivity | Choose for future-proofing or migration paths where memory headroom and peripheral count are limiting |
Compared with SAF-XC164CM-8F40F, the SAF-XC164KM-8F40F provides essential dual-CAN routing and gateway capability; versus SAF-XC2267-104F80L, it offers lower gate count and proven qualification for legacy industrial designs where extended Flash/RAM is not required.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time?
The SAF-XC164KM-8F40F AA achieves a maximum CPU clock frequency of 40 MHz, resulting in a 25 ns instruction cycle time for single-cycle executed instructions. This timing is guaranteed under specified voltage (5 V ± 10%) and temperature (-40 to +85 °C) conditions per the V1.2 datasheet, Section 4.3 AC Parameters.
Does this microcontroller support in-system programming (ISP) via its on-chip interfaces?
Yes - the SAF-XC164KM-8F40F AA includes an on-chip bootstrap loader accessible via ASC0 or ASC1, enabling in-system programming of Flash memory without external programming hardware. The bootloader supports standard UART framing and requires no external reset sequence beyond standard power-on or watchdog-initiated reset.
How many CAN message objects does the TwinCAN module support, and are they shared or independent?
The TwinCAN module supports 32 message objects total, allocated independently across its two CAN nodes (CAN0 and CAN1). Each node has dedicated message object RAM and acceptance filtering logic, allowing simultaneous transmission/reception on both buses without resource contention or arbitration delay.
Is the Real Time Clock (RTC) functional in all low-power modes?
The RTC remains active only in Idle and Sleep modes, powered by the backup domain supply. It is disabled in Power Down mode to minimize leakage current. The RTC calendar registers retain their values across Sleep mode, and wake-up events can be triggered by RTC alarm or periodic interrupt signals.
