Product details
Overview
C167CSL40MCABXUMA2 from Infineon Technologies is a 16-bit single-chip microcontroller with 32 KB on-chip mask ROM, 40 MHz maximum CPU clock, dual CAN 2.0B interfaces (30 message objects), 24-channel 10-bit ADC (7.8 µs conversion), and 111 GPIO lines. It integrates PLL-based clock generation, PEC-driven DMA, and real-time clock for industrial motion control and automotive body electronics.
For engineers reviewing the C167CSL40MCABXUMA2 datasheet, C167CSL40MCABXUMA2 pinout, C167CSL40MCABXUMA2 application, or C167CSL40MCABXUMA2 equivalent, key selection criteria include CAN object count, IRAM/XRAM allocation (3 KB/8 KB), 40 MHz timing compliance, and MQFP-144 package compatibility with legacy C166-family toolchains.
Technical Context
The C167CSL40MCABXUMA2 implements a 4-stage pipelined 16-bit CPU delivering 20 MIPS at 40 MHz, with register-based architecture enabling single-cycle context switching. Its peripheral event controller (PEC) supports interrupt-driven, single-cycle data transfers across eight channels independent of CPU intervention.
Two independent CAN 2.0B controllers each manage 15 message objects with full arbitration and error handling; combined operation on one bus enables 30-object message filtering. The on-chip PLL supports multiplication factors of 1.5× to 5×, allowing flexible clock synthesis from external crystal or oscillator inputs.
Key Specifications

FAQ
Does C167CSL40MCABXUMA2 support CAN FD?
No. The device implements Controller Area Network Revision 2.0B only, supporting standard 11-bit identifiers and up to 8-byte payloads per frame. CAN FD features such as variable bit rate and extended data length are not present in the silicon or firmware architecture.
What is the maximum operating temperature range for this part?
The C167CSL40MCABXUMA2 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed by Infineon's ordering code suffix "I" (e.g., "CABXUMA2" denotes industrial grade), and validated in DC characteristics tables on pages 52–53 of the V2.2 datasheet.
Is external memory required to run typical applications?
No. With 32 KB on-chip mask ROM, 3 KB IRAM, and 8 KB XRAM, the device supports self-contained operation for most control applications. External memory is optional and used only when code size exceeds 32 KB or runtime data storage exceeds 11 KB.
How is the watchdog timer configured and cleared?
The watchdog is enabled via WDTCON register bit WDTE; timeout period is set by WDTREL bits (16–256 ms range). It is cleared by writing 0x0000 to WDTCLEAR register. An oscillator watchdog monitors XTAL1/XTAL2 activity independently and triggers reset if oscillation stops.
