Product details
Overview
C164CI8E28MDBFXUMA1 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, and 64 KB mask-programmed ROM. It operates at up to 25 MHz (80 ns instruction cycle), supports 16-priority-level interrupts, and integrates CAPCOM2/6, 10-bit ADC, RTC, and PLL clock generation. Used in industrial motor control systems requiring deterministic real-time response and embedded CAN networking.
For engineers reviewing the C164CI8E28MDBFXUMA1 datasheet, C164CI8E28MDBFXUMA1 pinout, C164CI8E28MDBFXUMA1 application, or C164CI8E28MDBFXUMA1 equivalent, key selection criteria include CAN 2.0B compliance, 64 KB ROM content, full-function CAPCOM6 PWM capability, 80-pin MQFP package compatibility, and support for external bus expansion up to 4 MB.
Technical Context
The C164CI8E28MDBFXUMA1 implements a Harvard-architecture 16-bit CPU with register-based design, single-cycle context switching, and 16 MByte linear address space. Its peripheral set includes dual serial channels (asynchronous/synchronous/HS-sync), three independent timers, and a dedicated Peripheral Event Controller (PEC) enabling single-cycle data transfers across eight channels.
It integrates a full-function CAPCOM6 unit with three capture/compare channels and one dedicated compare channel for flexible PWM generation, alongside an 8-channel 10-bit ADC with programmable conversion time down to 7.8 µs. The on-chip CAN controller complies with ISO 11898 and supports both Full CAN and Basic CAN modes via 15 configurable message objects.

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, identical ROM content and pinout; differs only in ordering code suffix and packaging format (tape & reel vs. tray) | No functional difference; suitable for identical use cases including motor control and CAN gateways | Select when requiring standard tape-and-reel delivery for automated SMT lines |
| C167CS-LM | Successor derivative with 32 KB RAM, enhanced CAN (2.0B+), and 40 MHz max clock; larger 100-pin PQFP package | Enables more complex control algorithms and larger protocol stacks but requires PCB redesign and higher power budget | Choose for new designs needing extended memory, higher performance, or future-proofing beyond C164CI lifecycle |
Compared with SAK-C164CI-8R25M, this part offers identical functionality in tray packaging; compared with C167CS-LM, it trades raw performance and memory for lower cost, smaller footprint, and proven field reliability in mature industrial deployments.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the C164CI8E28MDBFXUMA1?
The device operates at up to 25 MHz with a 4-stage pipeline CPU, delivering an 80 ns instruction cycle time. This timing is confirmed in the May 2001 V2.0 datasheet revision, where "Operating frequency up to 25 MHz" is explicitly stated in the revision history and supported by the 12.5 MIPS performance figure derived from the 80 ns cycle.
Does the C164CI8E28MDBFXUMA1 include on-chip flash memory or is program storage limited to mask ROM?
This variant contains 64 KB of on-chip mask-programmed ROM only. The datasheet revision history explicitly states "References to Flash removed" in the May 2001 V2.0 update, confirming no flash memory is present. OTP versions (e.g., SAK-C164CI-8EM) exist but differ in ordering code and are not applicable to this ROM-based part.
How many CAN message objects does the on-chip CAN controller support, and what protocol version is implemented?
The integrated CAN interface supports exactly 15 message objects and implements CAN protocol version 2.0B active, as specified in the "On-Chip Peripheral Modules" section of the datasheet. This enables full mailbox arbitration, extended identifier support, and hardware error confinement required for industrial and automotive networks.
Is the C164CI8E28MDBFXUMA1 qualified for automotive applications, and what temperature range does it support?
The part is rated for industrial temperature range (–40 °C to +85 °C), as indicated by the "I" in the ordering code suffix and confirmed by Infineon's C164CI derivative tables. It is not AEC-Q100 qualified; automotive-grade variants (e.g., SAF-C164CI-8R25M) carry different suffixes and undergo additional qualification testing.
