Product details
Overview
C164CI8E25MDBKXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller in the C166 family, featuring a 4-stage pipeline CPU, on-chip CAN 2.0B interface with 15 message objects, 2 kB IRAM + 2 kB XRAM, 64 KB mask ROM, and operation at up to 25 MHz. It integrates CAPCOM2 (8-channel), CAPCOM6 (3/6 capture/compare + 1 compare), 10-bit ADC (7.8 µs min conversion), RTC, and PEC-driven DMA.
For engineers reviewing the C164CI8E25MDBKXUMA1 datasheet, C164CI8E25MDBKXUMA1 pinout, C164CI8E25MDBKXUMA1 application, or C164CI8E25MDBKXUMA1 equivalent, key selection considerations include CAN 2.0B compliance, 25 MHz max clock with PLL support (×1.5–×5), 80-pin MQFP package, full-function CAPCOM6, and industrial temperature range (–40°C to +85°C) operation.
Technical Context
The C164CI8E25MDBKXUMA1 implements a 16-bit C166 CPU core with 80 ns instruction cycle time at 25 MHz, supporting single-cycle context switching and 16 MByte linear address space. Its peripheral event controller (PEC) enables interrupt-driven, single-cycle data transfers across 8 channels.
It embeds a full-function CAPCOM6 unit (3/6 capture/compare + 1 dedicated compare channel), an 8-channel 10-bit ADC with programmable conversion down to 7.8 µs, and a fully compliant CAN 2.0B controller licensed from Robert Bosch GmbH with 15 message objects and hardware message filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-C164CI-8R25M | Same die, 64 KB ROM, identical pinout and peripheral set; differs only in ROM content and ordering code suffix. | No functional difference; intended for production programming with customer-specific firmware image. | Select when firmware is finalized and mask ROM programming is preferred over OTP or flash alternatives. |
| TMS320F28027PTT | 32-bit C28x DSP core, 60 MHz, no native CAN 2.0B (requires external transceiver + software stack), 12-bit 3.5 MSPS ADC. | Higher computational throughput but increased software complexity for CAN; better suited for advanced motor control with observer-based algorithms. | Choose only if >20 MIPS compute headroom and ≥12-bit ADC resolution are mandatory; accept added BOM cost and CAN stack validation effort. |
Compared with SAK-C164CI-8R25M, C164CI8E25MDBKXUMA1 offers identical functionality but with factory-programmed OTP instead of mask ROM-enabling engineering samples and low-volume prototyping. Versus TMS320F28027PTT, it delivers deterministic CAN 2.0B handling and lower system-level integration effort at the expense of raw DSP performance.

FAQ
Is C164CI8E25MDBKXUMA1 pin-compatible with other C164 derivatives?
Yes-it shares the identical 80-pin MQFP footprint and signal mapping with all C164CI/SI/CL/SL variants listed in Table 1 of the 2001 datasheet. Pin compatibility extends to power, clock, reset, and all port signals; differences exist only in CAPCOM6 functionality and CAN enablement, which are handled internally and do not affect board layout.
Does this part support in-system programming?
No-C164CI8E25MDBKXUMA1 uses one-time-programmable (OTP) ROM for program storage. Programming occurs once during manufacturing using Infineon's parallel programming interface (Vpp/EA-controlled); no bootloader or field reprogramming capability is provided, unlike flash-based successors.
What is the maximum ambient temperature rating for continuous operation?
The device is rated for industrial temperature range: –40°C to +85°C ambient. This is confirmed in the "Ordering Information" section of the datasheet and applies to all C164CI derivatives with "I" suffix (e.g., -8E25M indicates industrial grade). Junction temperature must remain below 125°C under worst-case power dissipation.
Can the on-chip CAN controller operate without an external transceiver?
No-the internal CAN module provides only the protocol controller (CAN IP core); physical layer signaling requires an external ISO 11898-compliant transceiver (e.g., Infineon TLE6250 or TI SN65HVD230) connected to the CANRX/CANTX pins (P4.5/P4.6) to drive the differential bus.
