Product details
Overview
C167CSLMCABXQLA1 from Infineon Technologies is a 16-bit single-chip microcontroller featuring a 4-stage pipeline CPU, 32 KB on-chip mask ROM, 3 KB IRAM, 8 KB XRAM, dual CAN 2.0B interfaces (30 message objects), and a 24-channel 10-bit ADC with 7.8 µs conversion time. It operates at up to 40 MHz (25 ns instruction cycle) and targets real-time industrial control systems requiring deterministic timing, multi-sensor data acquisition, and robust fieldbus communication.
For engineers reviewing the C167CSLMCABXQLA1 datasheet, C167CSLMCABXQLA1 pinout, C167CSLMCABXQLA1 application, or C167CSLMCABXQLA1 equivalent, key selection criteria include its dual-CAN support with full mailbox arbitration, programmable PLL clock generation (×1.5 to ×5), 111 GPIO lines with configurable thresholds, and integrated real-time clock - all in a 144-pin MQFP package.
Technical Context
The C167CSLMCABXQLA1 implements the C166 CPU core with register-based architecture, single-cycle context switching, and enhanced Boolean bit manipulation for efficient HLL and RTOS execution. Its peripheral event controller (PEC) enables interrupt-driven, single-cycle data transfers across 8 channels, decoupling CPU load from high-speed I/O operations.
Two independent CAN controllers (Rev. 2.0B active) each support 15 message objects with hardware acceptance filtering and automatic retransmission. The on-chip PLL provides precise clock synthesis from external crystal (1–20 MHz), while five programmable chip-select signals enable flexible memory mapping across up to 16 MB of external address space.

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 production. | Select when sourcing from alternate distributor channels where SAK-prefix is more readily available. |
| C167CR-LM | Legacy C167CR variant with 16 KB ROM, no dual-CAN, single 16-channel ADC, and 33 MHz max frequency. | Limited to simpler control tasks without CAN redundancy or high-speed sensor fusion. | Consider only for cost-sensitive legacy upgrades where dual-CAN and 40 MHz performance are not required. |
Compared with SAK-C167CS-4R40M (identical functionality) and C167CR-LM (reduced peripheral set), the C167CSLMCABXQLA1 delivers unique value in dual-CAN network resilience, 24-channel ADC throughput, and 40 MHz deterministic execution - critical for next-generation industrial automation nodes.

FAQ
Does C167CSLMCABXQLA1 support CAN FD?
No. The C167CSLMCABXQLA1 implements CAN 2.0B (ISO 11898-1:2003) only, with 11-bit standard identifiers and 29-bit extended identifiers. It lacks CAN FD features including bit-rate switching, extended data length (up to 64 bytes), and CRC enhancements. CAN FD support requires newer families such as Infineon's AURIX TC3xx series.
What is the maximum external memory address space supported?
The C167CSLMCABXQLA1 supports up to 16 MBytes of linear external address space for both code and data, using programmable chip-select signals (CS0–CS4) with configurable wait-state insertion, bus width (8/16-bit), and multiplexing mode - verified in Section 3.4 of the V2.2 datasheet.
Is the on-chip bootloader field-upgradable?
Yes. The device includes an on-chip bootstrap loader accessible via UART0 (P3.10/P3.11) that supports in-system programming of external Flash memory. It does not support reprogramming the internal 32 KB mask ROM, which is fixed at fabrication. Bootloader operation requires specific entry conditions (e.g., RSTIN low during power-on).
How many simultaneous CAN message objects can be handled?
The C167CSLMCABXQLA1 supports 30 total message objects across its two CAN controllers - 15 per controller. Each object includes dedicated identifier masking, direction control (Tx/Rx), and priority-based transmission arbitration. All 30 objects are accessible simultaneously with no software overhead for object switching.
