Infineon Technologies C164CI8EMDBFXUMA1

Overview

C164CI8EMDBFXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller featuring a 25 MHz CPU clock, 64 KB on-chip OTP program memory, full-function CAN 2.0B interface with 15 message objects, 8-channel 10-bit ADC (7.8 µs conversion), and integrated CAPCOM6 PWM unit. It operates at 5 V supply and targets embedded industrial control systems requiring real-time I/O, deterministic communication, and local signal conditioning.

For engineers reviewing the C164CI8EMDBFXUMA1 datasheet, C164CI8EMDBFXUMA1 pinout, C164CI8EMDBFXUMA1 application, or C164CI8EMDBFXUMA1 equivalent, key selection criteria include CAN 2.0B compliance, OTP programmability, 80-pin MQFP package compatibility, 10-bit ADC timing, and CAPCOM6 channel count for motor control waveform generation.

Technical Context

The C164CI8EMDBFXUMA1 implements the C166 CPU core with 4-stage pipeline, delivering 12.5 MIPS at 25 MHz and supporting single-cycle context switching via register banks. Its peripheral event controller (PEC) enables interrupt-driven, single-cycle data transfers across eight channels independent of CPU intervention.

On-chip clock generation uses a programmable PLL with multiplication factors of 1.5× to 5×, selectable prescaler, or direct external clock input. The CAN interface complies with ISO 11898 Rev. 2.0B and supports both Full CAN and Basic CAN modes with dedicated message object RAM and acceptance filtering.

FAQ

Does C164CI8EMDBFXUMA1 support in-system programming (ISP)?

No. The C164CI8EMDBFXUMA1 contains 64 KB of one-time programmable (OTP) memory, which can be programmed only once during manufacturing or final test using parallel programming equipment. It lacks flash memory or bootloader-based ISP capability. Field updates require replacement or external memory mapping.

What is the maximum ambient temperature rating for this device?

The C164CI8EMDBFXUMA1 is specified for industrial temperature range: –40 °C to +85 °C. This rating is confirmed in Infineon's ordering information documentation and applies to all C164CI derivatives in the 80-pin MQFP package, including the -8EM variant.

Can the on-chip CAN controller operate in Basic CAN mode only?

No. The on-chip CAN controller supports both Full CAN and Basic CAN modes per ISO 11898 Rev. 2.0B. Full CAN mode enables hardware-assisted message object management with 15 individually configurable objects, while Basic CAN provides simplified transmit/receive buffering - both modes are selectable via CAN control registers.

Is the CAPCOM6 unit capable of generating complementary PWM outputs with dead-time insertion?

No. The CAPCOM6 unit in C164CI8EMDBFXUMA1 supports independent channel compare/capture and flexible PWM edge alignment, but does not include hardware dead-time insertion logic. Dead-time must be implemented in software using timer synchronization and output pin toggling with precise cycle counting.
