Infineon Technologies SAK-XC161CS-32F20F BB-A

Overview

SAK-XC161CS-32F20F BB-A from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 CPU core, operating at up to 40 MHz with 25 ns instruction cycle time. It integrates 256 KB on-chip Flash, 12 KB SRAM (2 KB DPRAM + 4 KB DSRAM + 6 KB PSRAM), and dual CAN 2.0B interfaces (TwinCAN) with 32 message objects. Designed for automotive powertrain and industrial motor control, it supports real-time deterministic execution via 16-priority-level interrupts and hardware MAC.

For engineers reviewing the SAK-XC161CS-32F20F datasheet, SAK-XC161CS-32F20F pinout, SAK-XC161CS-32F20F application, or SAK-XC161CS-32F20F equivalent, key selection criteria include its -40 °C to 125 °C extended temperature grade, RoHS-compliant 144-pin TQFP package, TwinCAN gateway capability, 12-channel 10-bit ADC with 2.55 µs conversion, and JTAG-based on-chip debug support (OCDS).

Technical Context

The XC161CS-32F20F implements the C166SV2 16-bit RISC-like core with five-stage pipeline, zero-cycle jumps, and single-cycle 16×16 multiply. Its memory subsystem includes separate program/data SRAM banks and dual-port RAM for concurrent CPU/peripheral access, enabling deterministic real-time response in safety-critical loops.

Peripheral integration centers on deterministic I/O timing: TwinCAN supports concurrent transmission/reception on two nodes with hardware message filtering; GPT12E provides five independent timers with capture/compare; ASC0/ASC1 and SSC0/SSC1 offer configurable serial protocols; and the 12-channel ADC features programmable resolution (8/10-bit) and sample-and-hold synchronization.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The SAK-XC161CS-32F20F BB-A operates at up to 40 MHz CPU clock frequency, delivering a 25 ns instruction cycle time for single-cycle execution of most instructions. This timing is confirmed in Section 1 (Summary of Features) and Section 4.4 (AC Parameters) of the V1.2 datasheet, with PLL configuration enabling full-speed operation from external crystal sources.

Does this microcontroller support JTAG-based debugging and in-system programming?

Yes - the device includes full IEEE 1149.1-compliant JTAG interface (TDO, TDI, TCK, TMS pins) for boundary-scan testing, real-time debugging, and on-chip Flash programming. On-chip Debug Support (OCDS) is documented in Section 3.5 of the datasheet, enabling breakpoints, watchpoints, and register inspection without halting peripheral operation.

What are the ADC resolution and conversion time options?

The 12-channel ADC supports programmable resolution of either 10-bit or 8-bit, with minimum conversion times of 2.55 µs (10-bit) or 2.15 µs (8-bit). These values are specified in Section 3.9 and Table 11 (Analog/Digital Converter Parameters) of the datasheet, and conversion timing is synchronized to hardware triggers like PWM edges.

Is the TwinCAN module compatible with both Full CAN and Basic CAN protocols?

Yes - the TwinCAN module implements CAN 2.0B specification and supports both Full CAN (with identifier masking and acceptance filtering) and Basic CAN (with fixed message object allocation). Section 3.12 confirms 32 configurable message objects per node and gateway functionality between CAN0 and CAN1, enabling protocol translation in multi-network vehicles.
