Product details
Overview
C167CSL40MCAKXQLA1 from Infineon Technologies is a 16-bit single-chip microcontroller with 32 KB on-chip mask ROM, 40 MHz maximum CPU clock (25 ns instruction cycle), dual CAN 2.0B interfaces, 24-channel 10-bit ADC, 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 C167CSL40MCAKXQLA1 datasheet, C167CSL40MCAKXQLA1 pinout, C167CSL40MCAKXQLA1 application, or C167CSL40MCAKXQLA1 equivalent, key selection criteria include CAN object count (30 total), IRAM/XRAM allocation (3 KB/8 KB), and MQFP-144 package compatibility with legacy C166-family toolchains and PCB footprints.
Technical Context
The C167CSL40MCAKXQLA1 implements a 4-stage pipelined C166 CPU core with register-based architecture, supporting single-cycle context switching and 16 priority-level interrupts with 56 sources. Its peripheral event controller (PEC) enables interrupt-driven, single-cycle data transfers across eight channels independent of CPU execution.
On-chip peripherals include two 16-channel capture/compare units, a 4-channel PWM unit, two serial channels (asynchronous/synchronous/HS-synchronous), and dual CAN controllers compliant with ISO 11898 Rev. 2.0B - each supporting 15 message objects, configurable for Full or Basic CAN operation on a shared bus.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-C167CS-4R40M | Same die, identical mask ROM content and pinout; differs only in ordering code suffix (no functional difference). | No application difference; fully interchangeable in design and qualification. | Select when sourcing from Infineon's official distribution channel with full traceability and extended lifecycle support. |
| C167CR-L40M | ROM-less variant with external program memory interface; lacks on-chip 32 KB mask ROM but adds enhanced boot ROM and flash programming support. | Suitable for prototyping or field-upgradable systems; not drop-in replaceable due to missing ROM and altered reset vector mapping. | Choose for development flexibility where firmware updates are required post-deployment; requires external memory redesign. |
Compared with SAK-C167CS-4R40M (identical function) and C167CR-L40M (ROM-less alternative), the C167CSL40MCAKXQLA1 delivers production-ready firmware integration and deterministic boot behavior - critical for certified industrial and medical devices where ROM integrity and startup repeatability are mandatory.

FAQ
What is the maximum operating temperature range for C167CSL40MCAKXQLA1?
The C167CSL40MCAKXQLA1 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Infineon's C167CS Data Sheet V2.2 (2001), Section 5 "Limiting Values", Table 11. Operation outside this range may cause timing violations or data retention loss in on-chip RAM.
Does C167CSL40MCAKXQLA1 support in-system programming (ISP)?
No - C167CSL40MCAKXQLA1 contains mask-programmed ROM and lacks on-chip flash or EEPROM. Firmware is fixed at fabrication. Programming occurs only during wafer mask definition; field updates require external memory or bootloader-mediated code relocation, not ISP.
Can both CAN interfaces operate simultaneously on the same physical bus?
Yes - the dual CAN controllers can share one differential bus using software-configured message object arbitration. Each controller manages 15 objects independently, allowing 30 total mailboxes with distinct ID filters and transmission priorities for complex diagnostics and redundancy schemes.
Is the 24-channel ADC truly simultaneous sampling or multiplexed?
The ADC is multiplexed: only one channel converts at a time, though conversion time is programmable down to 7.8 µs per channel. Simultaneous sampling is not supported; however, rapid sequential sampling across multiple channels (e.g., three-phase currents) achieves effective near-simultaneity within <24 µs for coordinated control.
