Product details
Overview
C164CI8EMDBKXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller in the C166 family, featuring an on-chip 64 KB OTP program memory, full-function CAN 2.0B interface with 15 message objects, and operation up to 25 MHz at 5 V supply. It integrates 2 KB IRAM, 2 KB XRAM, 8-channel 10-bit ADC (7.8 µs conversion), CAPCOM2/6 units, three timers, dual serial channels, RTC, and PLL clock generation.
For engineers reviewing the C164CI8EMDBKXUMA1 datasheet, C164CI8EMDBKXUMA1 pinout, C164CI8EMDBKXUMA1 application, or C164CI8EMDBKXUMA1 equivalent, key selection criteria include OTP-based firmware immutability, full CAN 2.0B support for automotive body control networks, 80 ns instruction cycle time, and 80-pin MQFP package compatibility with legacy C164CI designs requiring external bus expansion.
Technical Context
The C164CI8EMDBKXUMA1 implements a 4-stage pipelined 16-bit CPU delivering 12.5 MIPS at 25 MHz, with register-based architecture enabling single-cycle context switching and 16 MByte linear address space. Its peripheral set includes a dedicated CAN controller licensed from Robert Bosch GmbH, supporting both Full and Basic CAN modes via 15 configurable message objects.
On-chip timing resources comprise a programmable PLL (1.5×–5× multiplication), oscillator watchdog, and power management with Idle/Sleep/Power Down modes. Memory mapping supports up to 4 MBytes external code/data space with four programmable chip-selects, demultiplexed/multiplexed bus options, and 8-/16-bit data width configuration.

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 | 64 KB mask ROM instead of OTP; identical peripheral set and pinout | Requires ROM mask tape-out; unsuitable for prototyping or low-volume customization | Select when firmware is finalized and volume exceeds 10k units to reduce unit cost |
| SAK-C164CL-8R25M | Reduced-function CAPCOM6 (no CC16–CC19 outputs); retains full CAN 2.0B | Lacks dedicated PWM outputs for 3-phase motor control; limited to single/dual-channel PWM | Select for cost-sensitive CAN nodes where advanced PWM is unnecessary (e.g., lighting control) |
Compared with SAK-C164CI-8R25M, C164CI8EMDBKXUMA1 offers field-programmable OTP for design iteration and small-batch deployment; versus SAK-C164CL-8R25M, it delivers full CAPCOM6 functionality essential for complex timing-critical peripherals like motor gate drivers.

FAQ
Is C164CI8EMDBKXUMA1 pin-compatible with other C164CI derivatives?
Yes, all C164CI variants including SAK-C164CI-8R25M and SAK-C164CL-8R25M use the identical 80-pin MQFP package and share identical pin functions for core peripherals (CAN, ADC, timers, serial). Differences exist only in OTP vs ROM memory and CAPCOM6 feature enablement, which are masked internally and do not affect pin behavior.
Does C164CI8EMDBKXUMA1 support in-system programming?
No. The 64 KB OTP memory requires parallel programming via dedicated programmers (e.g., Infineon TAP-based tools) before soldering. Once programmed, contents are permanent and cannot be erased or rewritten - this ensures firmware security but precludes field updates.
What is the maximum operating temperature range for this part?
C164CI8EMDBKXUMA1 is specified for industrial temperature range: –40 °C to +85 °C. This is confirmed in Infineon's ordering information documentation and applies to all C164CI derivatives in MQFP packaging, with thermal derating beyond 70 °C per datasheet Section 5.2.
Can the on-chip CAN controller operate in Basic CAN mode only?
No. The device implements full CAN 2.0B compliance, supporting both Standard (11-bit) and Extended (29-bit) identifier frames, message object prioritization, and hardware acceptance filtering. Basic CAN mode is a subset enabled automatically when only 11-bit IDs are configured - no functional limitation exists.
