For engineers reviewing the C164CILMCAKXUMA1 datasheet, C164CILMCAKXUMA1 pinout, C164CILMCAKXUMA1 application, or C164CILMCAKXUMA1 equivalent, key selection criteria include its full-function CAPCOM6 unit, integrated CAN controller, 8-channel 10-bit ADC with 7.8 µs conversion time, and 80-pin MQFP package with programmable I/O thresholds.
Technical Context
The C164CILMCAKXUMA1 implements a high-performance 16-bit CPU core with 80 ns instruction cycle time at 25 MHz, supporting single-cycle context switching and 16 MByte linear address space. Its peripheral set includes a 3-timer unit, dual serial channels (asynchronous + high-speed synchronous), and an on-chip real-time clock.
It integrates a dedicated CAN 2.0B controller licensed from Robert Bosch GmbH, with full CAN functionality including message object management and automatic retransmission. The device uses an on-chip PLL for clock generation with selectable multiplication factors (1.5× to 5×) and supports idle, sleep, and power-down modes with oscillator watchdog and programmable watchdog timer.

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-C164CI-8R25M | Same die, identical peripherals and pinout; differs only in ROM content and marking | Mask-ROM variant with fixed firmware image; not field-programmable | Select when firmware is finalized and volume production requires lowest unit cost |
| C167CR-LM | Enhanced C166 derivative with 32 KB RAM, 512 KB flash, and extended CAN FIFO; larger package (144-pin LQFP) | Supports complex RTOS-based applications and over-the-air updates | Select when future firmware scalability or flash-based development is required |
Compared with SAK-C164CI-8R25M, C164CILMCAKXUMA1 offers identical hardware but different ROM programming and ordering code; compared with C167CR-LM, it trades memory and flash flexibility for lower cost, smaller footprint, and optimized CAN+motor control integration.

FAQ
What is the maximum operating frequency and corresponding instruction throughput?
The C164CILMCAKXUMA1 operates at up to 25 MHz with an 80 ns instruction cycle time, delivering 12.5 million instructions per second (MIPS). This performance level is sustained across all on-chip peripherals, including CAN message handling and ADC conversions, without wait states in internal memory access.
Does this microcontroller support in-system programming or field firmware updates?
It includes an on-chip bootstrap loader accessible via UART0, enabling firmware updates using a host PC and standard serial interface-no external programmer required. However, as a mask-ROM device, the main application code is factory-programmed and not reprogrammable in the field.
How many CAN message objects does the on-chip CAN controller support?
The integrated CAN 2.0B controller supports exactly 15 message objects, each configurable as transmit or receive with individual ID masking and priority assignment. This allows concurrent handling of multiple CAN identifiers without CPU intervention during message transmission or reception.
What are the key differences between full-function and reduced-function CAPCOM6 units?
The full-function CAPCOM6 (present in C164CILMCAKXUMA1) provides 3/6 capture/compare channels and 1 dedicated compare channel for flexible PWM generation. Reduced-function versions omit two capture channels and lack the dedicated compare channel, limiting multi-phase motor control capability and waveform complexity.
