Product details
Overview
SAF-XC164GM-16F40F 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 integrated TwinCAN 2.0B interface with 32 message objects across two CAN nodes. It operates at 40 MHz CPU clock (25 ns instruction cycle), supports 16-priority-level interrupts with 50 ns sample rate, and targets automotive body control and industrial motor drive applications requiring deterministic real-time response.
For engineers reviewing the SAF-XC164GM-16F40F datasheet, SAF-XC164GM-16F40F pinout, SAF-XC164GM-16F40F application, or SAF-XC164GM-16F40F equivalent, key selection criteria include its 128 KB Flash capacity, dual CAN node support with gateway functionality, 14-channel 10-bit ADC (2.55 µs conversion), CAPCOM2 unit for PWM generation, and JTAG-based on-chip debug support - all in a RoHS-compliant 64-pin LQFP package.
Technical Context
The SAF-XC164GM-16F40F implements the C166SV2 16-bit CPU core with five-stage pipeline, enabling single-cycle execution of most instructions and 1-cycle 16×16 multiplication. Its interrupt system delivers 50 ns minimum sample rate across 63 sources with 16 priority levels, managed via hardware-assisted context switching using two local register banks.
Peripheral integration includes a 14-channel, programmable-resolution (8/10-bit) ADC with configurable conversion time down to 2.55 µs; a 16-channel CAPCOM2 unit supporting edge-aligned and center-aligned PWM; and a TwinCAN module compliant with ISO 11898-1:2003 (CAN 2.0B active), supporting full CAN and Basic CAN modes plus inter-node message forwarding.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-16F40F | Same C166SV2 core, identical 128 KB Flash and RAM map, but lacks TwinCAN - only single CAN node (CAN0) | Not suitable for dual-CAN gateway or distributed vehicle networks requiring inter-node messaging | Select only if application uses one CAN domain and requires cost reduction over dual-CAN capability |
| SAF-XC2267M-104F80L | Successor-generation 32-bit TriCore™ core, 80 MHz, 1 MB Flash, dual CAN FD, but larger 100-pin LQFP package and higher voltage supply (3.3 V) | Requires PCB redesign and toolchain migration; supports CAN FD and safety features (ASIL-B ready) | Choose for new designs needing CAN FD bandwidth or functional safety compliance; not drop-in compatible |
Compared with SAF-XC164CS-16F40F, the SAF-XC164GM-16F40F provides essential dual-CAN gateway capability for vehicle network segmentation; versus SAF-XC2267M-104F80L, it offers proven 16-bit deterministic latency and pin-compatible upgrade path within legacy LQFP-64 footprints, avoiding redesign overhead.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time?
The SAF-XC164GM-16F40F achieves a maximum CPU clock of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution of most instructions. This timing is enabled by the C166SV2 core's five-stage pipeline and verified under specified voltage (5.0 V ± 10%) and temperature (-40 to +85 °C) conditions per the V1.2 datasheet.
Does this microcontroller support in-application programming (IAP) of Flash memory?
Yes - the SAF-XC164GM-16F40F supports in-system programming (ISP) and in-application programming (IAP) of its 128 KB Flash memory via the on-chip bootstrap loader and JTAG interface. Flash sectors can be erased and reprogrammed without external programmers, enabling field firmware updates and parameter storage.
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 - critical for gateway and distributed control use cases.
Is the Real Time Clock (RTC) battery-backed, and what clock source does it use?
No - the RTC is not battery-backed. It is driven exclusively by the main oscillator (XTAL1/XTAL2 input), and continues operation only when the main oscillator is active and the device is not in Power Down mode. The RTC retains time during Idle and Sleep modes but resets upon full power-down or oscillator stop.
