Infineon Technologies SAK-XC167CI-32F20F BB-A

Overview

SAK-XC167CI-32F20F BB-A from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 256 KB on-chip Flash, 12 KB total SRAM (2 KB DPRAM + 4 KB DSRAM + 6 KB PSRAM), and operation up to 40 MHz CPU clock (25 ns instruction cycle). It integrates TwinCAN 2.0B (dual-node, 32 message objects), 16-channel 10-bit ADC (2.55 µs conversion), and CAPCOM6 for flexible PWM generation. Used in automotive powertrain control and industrial motor drives requiring deterministic real-time response.

For engineers reviewing the SAK-XC167CI-32F20F datasheet, SAK-XC167CI-32F20F pinout, SAK-XC167CI-32F20F application, or SAK-XC167CI-32F20F equivalent, key selection criteria include its -40 °C to 125 °C extended temperature grade, JTAG-based OCDS debug support, dual CAN interface with gateway capability, and programmable external bus controller supporting up to 12 MB address space.

Technical Context

The XC167CI-32F20F implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and MAC instructions-enabling deterministic interrupt latency down to 50 ns across 77 sources. Its memory subsystem includes separate dual-port RAM for concurrent CPU/peripheral access and flash wait-state control via IMBCTRL register.

Peripheral integration centers on real-time I/O coordination: the Peripheral Event Controller (PEC) enables single-cycle DMA transfers using 24-bit pointers; CAPCOM6 provides independent capture/compare channels for 3-phase motor commutation; and the TwinCAN module supports full CAN protocol with hardware message filtering and automatic retransmission on both nodes.

FAQ

What is the maximum operating frequency of the SAK-XC167CI-32F20F BB-A CPU core?

The C166SV2 core operates at up to 40 MHz, delivering a 25 ns instruction cycle time. This frequency is achieved using the on-chip PLL with programmable multiplication factors (1:0.15 to 1:10) and requires proper flash wait-state configuration via the WSFLASH bitfield in IMBCTRL register to ensure reliable execution.

Does the SAK-XC167CI-32F20F BB-A support CAN FD or only classical CAN?

The SAK-XC167CI-32F20F BB-A implements TwinCAN Rev. 2.0B only, supporting classical CAN with data rates up to 1 Mbit/s. It does not support CAN FD features such as flexible data-rate or extended frame formats. CAN FD capability requires newer derivatives like the XC2267M or AURIX families.

How many independent PWM channels can be generated using CAPCOM6?

CAPCOM6 provides three dedicated capture/compare channels and one additional compare channel, enabling generation of up to six independent PWM outputs. These channels support programmable dead-time insertion, edge/center-aligned modes, and hardware fault shutdown-critical for 3-phase inverter control.

Is JTAG debugging supported, and what debug capabilities does it provide?

Yes, the device supports full JTAG-based On-Chip Debug Support (OCDS), including real-time trace, hardware breakpoints, watchpoints, register inspection, and memory read/write during run-time. TRST signal behavior is defined in datasheet revision V1.1 (page 13), and OCDS operates independently of CPU clock domain for non-intrusive debugging.
