It targets real-time industrial control systems requiring deterministic interrupt response, motor phase timing, and embedded networking.
For engineers reviewing the C167CRL33MHAKXUMA2 datasheet, C167CRL33MHAKXUMA2 pinout, C167CRL33MHAKXUMA2 application, or C167CRL33MHAKXUMA2 equivalent, key selection criteria include its 33 MHz PLL-synchronized execution, 16-priority-level interrupt system with 40 ns sample rate, 176-ball BGA package (P-BGA-176-2), and full-CAN message object support for automotive body control and industrial PLC I/O modules.
Technical Context
The C167CRL33MHAKXUMA2 implements a 4-stage pipelined C166-core CPU with register-based architecture, single-cycle context switching, and 16 Mbyte linear address space. Its memory map integrates 128 KB mask ROM, 2 KB XRAM, and 2 KB IRAM, with external bus controller supporting multiplexed/demultiplexed 8/16-bit data buses and five programmable chip-selects.
Peripheral integration includes two CAPCOM units (16 channels each), a 4-channel PWM module, dual GPT units (5 timers total), dual serial channels (asynchronous/synchronous/HS-sync), and a dedicated CAN 2.0B module with 15 message objects, programmable bit timing, and full-CAN/BASIC-CAN operation modes.

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-C167CR-16R33M | Same die, MQFP-144 package (144-pin quad flat pack) instead of BGA; identical ROM/XRAM/CPU specs. | Better suited for prototyping and manual assembly; lacks BGA's thermal performance and I/O density. | Select when board reworkability or cost-sensitive low-volume production is prioritized over thermal/power density. |
| C167CS-16R33M | Successor derivative with enhanced CAN timing resolution, extended temperature range (−40°C to +125°C), and updated errata fixes. | Required for new designs targeting extended ambient operation or stricter CAN timing compliance (e.g., ISO 11898-1:2015). | Choose for new industrial designs needing long-term availability and improved thermal robustness beyond −40°C to +85°C. |
Compared with SAB-C167CR-16R33M, the C167CRL33MHAKXUMA2 offers superior thermal dissipation and higher I/O count in BGA form; versus C167CS-16R33M, it lacks extended temperature qualification and later silicon errata corrections but remains viable for legacy-replacement and cost-constrained applications.

FAQ
What is the maximum operating temperature range for C167CRL33MHAKXUMA2?
The C167CRL33MHAKXUMA2 is rated for operation from −40 °C to +85 °C ambient temperature, as specified in Section 4.1 of the V3.3 datasheet. This range applies to the P-BGA-176-2 package under natural convection cooling with ≤0.5 W total power dissipation. Derating is required above 70 °C for sustained 33 MHz operation.
Does C167CRL33MHAKXUMA2 support in-system programming (ISP)?
No, C167CRL33MHAKXUMA2 contains mask-programmed ROM and does not support ISP. Firmware is permanently written during wafer fabrication. Field updates require the on-chip bootstrap loader communicating via UART to load new code into external memory or execute from XRAM, but ROM contents cannot be altered post-manufacture.
How many CAN message objects are implemented in hardware?
The C167CRL33MHAKXUMA2 implements 15 dedicated message objects in hardware within its CAN module, as confirmed in Section 3.10 and Table 12 of the datasheet. Each object supports full CAN 2.0B identifier filtering, transmit/receive direction control, and automatic mailbox management without CPU polling.
Is the A/D converter compatible with 5 V analog inputs?
The A/D converter accepts analog inputs up to AVDD (typically 5 V), but its reference voltage (VREF) is internally tied to AVDD. Input signals must remain within 0 V to AVDD; applying 5 V to a channel referenced to 5 V yields full-scale 1023 (10-bit). External scaling is required for inputs exceeding AVDD or requiring ratiometric accuracy against a separate reference.
