Product details
Overview
C164CILM3VCABXUMA1 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 with 5 V supply and supports real-time control in automotive body electronics and industrial motion systems.
For engineers reviewing the C164CILM3VCABXUMA1 datasheet, C164CILM3VCABXUMA1 pinout, C164CILM3VCABXUMA1 application, or C164CILM3VCABXUMA1 equivalent, key selection criteria include CAN 2.0B compliance, 8-channel 10-bit ADC with 7.8 µs conversion time, CAPCOM6-based PWM generation, 16-priority interrupt system, and 80-pin MQFP package compatibility with external bus expansion.
Technical Context
The C164CILM3VCABXUMA1 implements a full-function CAN 2.0B controller licensed from Robert Bosch GmbH, supporting both Full CAN and Basic CAN modes with dedicated message object RAM and automatic ID filtering. Its CAPCOM6 unit provides three capture/compare channels and one dedicated compare channel for flexible PWM signal generation with programmable dead-time insertion.
It integrates a PLL-based clock generator with selectable multiplication factors (1.5× to 5×), enabling precise timing control across variable system clocks. The peripheral event controller (PEC) delivers single-cycle, interrupt-driven data transfers across eight channels, decoupling CPU load from high-speed I/O operations such as ADC sampling or serial communication.

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 CAN/CAPCOM6/ADC specs; differs only in ROM content and marking. | No functional difference; intended for production programming with customer-specific firmware image. | Select when requiring factory-programmed ROM with validated application code and traceable lot history. |
| SAF-C164CI-L25M | ROM-less variant with external boot ROM support; same peripheral set and pinout. | Requires external memory for program storage; suited for prototyping or firmware-upgradable designs. | Select when flexibility in firmware updates or debug access outweighs cost sensitivity of integrated ROM. |
Compared with SAK-C164CI-8R25M, C164CILM3VCABXUMA1 offers identical functionality but with finalized mask ROM and extended temperature qualification; versus SAF-C164CI-L25M, it eliminates external memory dependency while increasing boot reliability in harsh environments.

FAQ
Does C164CILM3VCABXUMA1 support CAN FD?
No. This device implements CAN 2.0B (Rev. 2.0B active), supporting data frames up to 8 bytes and 11-bit standard identifiers. CAN FD capability requires newer derivatives such as the XC2000 or Aurix families. The C164CI's CAN module lacks bit-rate switching and extended data length features defined in ISO 11898-1:2015.
What is the maximum operating temperature range for this part?
C164CILM3VCABXUMA1 is qualified for industrial temperature range: –40 °C to +85 °C. It does not carry automotive AEC-Q100 qualification. Thermal derating begins above 70 °C ambient when operating at 25 MHz with full peripheral activation, requiring board-level thermal design per Infineon Application Note AN2001-05.
Can the on-chip XRAM be used as stack space?
Yes. The 2 KB XRAM is fully accessible as general-purpose RAM and may be configured as stack space via linker script or startup code. It resides in the lower 64 KB data address space and supports byte/word access with no wait states at 25 MHz, making it suitable for deep nested interrupt stacks in real-time OS environments.
Is there hardware support for USB or Ethernet connectivity?
No. C164CILM3VCABXUMA1 lacks native USB or Ethernet MAC/PHY peripherals. Connectivity must be implemented externally via UART-to-USB bridge ICs (e.g., CP2102) or SPI-connected Ethernet controllers (e.g., ENC28J60). Its two serial channels support only asynchronous UART, synchronous SSC, and high-speed synchronous modes-not USB or IEEE 802.3 protocols.
