Product details
Overview
C167CSL40MCAKXQLA2 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 motor control and automotive body electronics.
For engineers reviewing the C167CSL40MCAKXQLA2 datasheet, C167CSL40MCAKXQLA2 pinout, C167CSL40MCAKXQLA2 application, or C167CSL40MCAKXQLA2 equivalent, key selection criteria include CAN object count, 10-bit ADC resolution and speed, 40 MHz timing compliance, and MQFP-144 package compatibility with legacy C166-family toolchains.
Technical Context
The C167CSL40MCAKXQLA2 implements a 4-stage pipelined 16-bit CPU delivering up to 20 MIPS at 40 MHz, with register-based architecture enabling single-cycle context switching. Its peripheral set includes two independent CAN controllers licensed from Bosch, each supporting 15 message objects in Full CAN mode.
On-chip memory comprises 3 KB IRAM, 8 KB XRAM, and 32 KB mask-programmed ROM. The 24-channel ADC supports programmable sampling time down to 7.8 µs, while the dual 16-channel capture/compare units and 4-channel PWM unit enable precise motor phase control and timer-synchronized I/O.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 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) | Identical use cases - direct drop-in replacement with same qualification and traceability | Select when requiring Infineon's standard SAK prefix for procurement systems |
| C167CR-L40M | ROM-less variant with external boot ROM interface; lacks on-chip 32 KB mask ROM | Requires external memory for firmware; suitable only where field-upgradable code is mandatory | Choose only if firmware flexibility outweighs added BOM cost and PCB footprint of external ROM |
Compared with SAK-C167CS-4R40M (identical functionality, different ordering code) and C167CR-L40M (ROM-less, requires external boot), the C167CSL40MCAKXQLA2 delivers fixed, production-qualified firmware in minimal footprint - optimal for cost-sensitive, high-volume embedded control where code stability is critical.

FAQ
Does C167CSL40MCAKXQLA2 support in-circuit debugging?
Yes - it supports on-chip debug via Infineon's DAS (Debug Access Service) interface using standard JTAG adapters. The device includes dedicated debug registers and breakpoint logic compatible with Infineon's DAS500 emulator and third-party tools supporting C166-core JTAG protocols.
What is the maximum operating temperature range for this part?
The C167CSL40MCAKXQLA2 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Table 1 of the V2.2 datasheet under "C167CS-L" derivative specifications, and applies to all MQFP-144 packaged variants including this ordering code.
Can the on-chip 32 KB ROM be reprogrammed in-system?
No - the 32 KB program memory is mask ROM, programmed during wafer fabrication. It cannot be erased or rewritten. Firmware updates require replacing the physical device or using an external flash memory with boot-from-external configuration enabled via EA pin.
Is CAN FD supported on this microcontroller?
No - the C167CSL40MCAKXQLA2 implements CAN 2.0B only (ISO 11898-1:1993), supporting up to 1 Mbit/s with 11-bit identifiers. CAN FD features (flexible data rate, extended identifiers) were not introduced until later Infineon families such as the XMC4000 series.
