Overview
XC167CI16F40FBBFXQMA1 from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 CPU core, featuring 128 KB on-chip Flash, 2 KB DPRAM, 4 KB DSRAM, and 2 KB PSRAM. It integrates TwinCAN (Rev. 2.0B), dual ASC/SSC interfaces, a 16-channel 10-bit ADC (2.55 µs conversion), CAPCOM6 PWM unit, and real-time clock - deployed in automotive engine control units and industrial motor drives.
For engineers reviewing the XC167CI16F40FBBFXQMA1 datasheet, XC167CI16F40FBBFXQMA1 pinout, XC167CI16F40FBBFXQMA1 application, or XC167CI16F40FBBFXQMA1 equivalent, key selection criteria include CAN 2.0B dual-node support, 40 MHz CPU clock with 25 ns instruction cycle, 1-cycle MAC, JTAG-based OCDS debug, and RoHS-compliant 144-pin TQFP package with 0.5 mm pitch.
Technical Context
The XC167CI16F40FBBFXQMA1 implements a 5-stage pipelined C166SV2 core delivering single-cycle execution at 40 MHz (25 ns), with hardware-accelerated 16×16 multiply, 32/16 divide (21 cycles), and MAC operations. Its memory subsystem supports 16 MB linear address space, including on-chip Flash with erase/write cycle endurance of ≥10k cycles and data retention ≥20 years.
Peripheral integration includes two independent CAN controllers (32 message objects, gateway mode), dual ASC (UART) and SSC (SPI-like) channels, GPT12E timer with five sub-timers, and CAPCOM6 for flexible 3-phase PWM generation - all synchronized via a programmable PLL (1:0.15–1:10) and prescaler (1:1–60:1).

FAQ
Does XC167CI16F40FBBFXQMA1 support CAN FD?
No. The XC167CI16F40FBBFXQMA1 implements TwinCAN compliant with ISO 11898-1:2003 (CAN 2.0B), supporting only classical 11-bit identifiers and 8-byte payloads. It does not support CAN FD's variable bit rate or extended data length. For CAN FD, consider Infineon's AURIX™ TC2xx or TC3xx families.
What debug interface does XC167CI16F40FBBFXQMA1 use?
The device uses JTAG-based On-Chip Debug Support (OCDS) per IEEE 1149.1, supporting full boundary-scan, real-time trace, hardware breakpoints, and register access. It requires an Infineon DAS or compatible JTAG emulator (e.g., Lauterbach TRACE32) - no SWD or serial wire debug capability is implemented.
Is the on-chip Flash memory reprogrammable in-system?
Yes. The 128 KB Flash supports in-system programming (ISP) via the on-chip bootstrap loader using ASC0 or ASC1. Erase granularity is sector-based (4 KB minimum), with typical write time of 10 ms per 128-byte page and full chip erase in ~2 s. No external HV programming voltage is required.
What is the maximum ambient temperature rating for continuous operation?
The XC167CI16F40FBBFXQMA1 is rated for continuous operation from −40 °C to +125 °C ambient, validated per AEC-Q100 Grade 0 requirements. Junction temperature must remain ≤150 °C; thermal design must account for RΘJC = 12.5 K/W and PCB copper area per Infineon's AN2006-08 layout guidelines.
