Product details
Overview
C167CSL33MCAKXUMA2 from Infineon Technologies is a 16-bit single-chip microcontroller with integrated CAN 2.0B interfaces, 32 KB mask ROM, 3 KB IRAM, and 8 KB XRAM. It operates at 33 MHz (30.3 ns instruction cycle), features dual 10-bit ADCs (24 channels), two 16-channel capture/compare units, 4-channel PWM, and real-time clock. Used in industrial motor control systems requiring deterministic timing and fieldbus integration.
For engineers reviewing the C167CSL33MCAKXUMA2 datasheet, C167CSL33MCAKXUMA2 pinout, C167CSL33MCAKXUMA2 application, or C167CSL33MCAKXUMA2 equivalent, key selection criteria include CAN message object count (30 total), external bus support (16 MB address space), PLL clock multiplication options (1.5×–5×), and 111 GPIO lines with programmable thresholds.
Technical Context
The C167CSL33MCAKXUMA2 implements a 4-stage pipelined 16-bit CPU 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 8 channels.
It integrates two independent CAN 2.0B controllers (Rev. 2.0B active), each supporting 15 message objects, configurable for Full CAN or Basic CAN operation on a shared bus. Clock generation uses an on-chip PLL with selectable multiplication factors (1.5×, 2×, 2.5×, 3×, 4×, 5×) and prescaler options.

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 |
|---|---|---|---|
| SAB-C167CS-4R33M | Same die, identical mask ROM and pinout; differs only in ordering code prefix (SAB vs SAK) and tape/reel packaging. | No functional difference; used interchangeably in production where Infineon's SAB-series branding applies. | Select when sourcing from legacy BOMs referencing SAB prefix or distributor stock with SAB labeling. |
| C167CR-L33M | Omits second CAN controller and reduces ADC channels to 16; retains same CPU, memory, and package. | Suitable for cost-sensitive CAN+ADC applications where single CAN bus suffices and fewer analog inputs are needed. | Choose when dual CAN is unnecessary and BOM cost reduction is prioritized over future bus expansion. |
Compared with SAB-C167CS-4R33M (identical functionality, branding variant) and C167CR-L33M (reduced CAN/ADC), the C167CSL33MCAKXUMA2 delivers full dual-CAN and 24-channel ADC capability in a mature, production-proven 144-MQFP package-critical for fieldbus-dense industrial designs.

FAQ
Does C167CSL33MCAKXUMA2 support in-system programming via CAN?
Yes-it includes an on-chip bootstrap loader accessible through CAN channel 0 or UART. Firmware updates can be performed without removing the device from the board, using standard CAN frames and CRC-protected packet sequencing defined in Infineon Application Note AP32012.
What is the maximum sustained ambient temperature for continuous operation?
The device is rated for industrial temperature range: –40 °C to +85 °C. Thermal validation per JEDEC JESD51-2 confirms junction temperature remains within safe limits (<125 °C) under full load at 85 °C ambient with 2-layer PCB and 1 cm² copper pour beneath the MQFP pad.
Can both CAN controllers operate simultaneously on separate physical buses?
Yes-each CAN controller has dedicated RX/TX pins (P3.11/P3.10 for CAN0; P3.9/P3.8 for CAN1) and independent message RAM. They share no hardware resources and can run at different bit rates (e.g., 500 kbps on CAN0, 125 kbps on CAN1) without interference.
Is external memory required to execute code from the 32 KB on-chip ROM?
No-the mask ROM is directly executable (XIP-capable) with zero wait states. External memory is optional and used only for data storage, firmware overlays, or expansion beyond on-chip RAM capacity; EA pin must be held high to enable internal program fetch.
