Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-C164CI-8R25M | Same die, 64 KB ROM instead of OTP; no internal bootloader support | Fixed firmware only; unsuitable for field-upgradable systems | Select when firmware is finalized and cost sensitivity outweighs programming flexibility |
| SAK-C164CL-8R25M | Reduced CAPCOM6 (3-channel only); no CAN interface | Lacks CAN 2.0B and full PWM capability - limited to standalone control tasks | Choose for non-networked applications where CAN and multi-phase PWM are unnecessary |
Compared with SAK-C164CI-8R25M, C164CI8E25MDBFXUMA1 offers field-programmable OTP memory and integrated bootstrap loader for firmware updates; versus SAK-C164CL-8R25M, it retains full CAN and 6-channel CAPCOM6 - essential for distributed motor control networks.

FAQ
What is the maximum external memory address space supported by C164CI8E25MDBFXUMA1?
The device supports up to 4 MBytes of external address space for both code and data, with four programmable chip-select signals (CS0–CS3) enabling independent configuration of wait states, bus width (8-/16-bit), and multiplexing mode per region. External bus timing is fully software-configurable via the BUSCON registers.
Does C164CI8E25MDBFXUMA1 support JTAG debugging?
No, C164CI8E25MDBFXUMA1 does not implement JTAG. Debugging relies on Infineon's OCDS (On-Chip Debug Support) interface using dedicated pins (TDO, TDI, TCK, TMS) and requires compatible emulators such as the DAS500 or UDE-based tools. The on-chip bootstrap loader enables UART-based firmware loading without debug hardware.
Can the on-chip CAN controller operate in silent mode for bus monitoring?
Yes, the CAN module supports silent mode (self-test mode), where the transmitter is disabled while the receiver remains active - allowing non-intrusive bus traffic monitoring and protocol analysis without affecting network operation. This mode is configured via the CANMOD register's SM bit.
What is the operating voltage range and temperature grade for this part?
C164CI8E25MDBFXUMA1 operates at a nominal supply voltage of 5 V ±10% (4.5 V to 5.5 V) and is rated for industrial temperature range (–40 °C to +85 °C). It includes internal voltage regulation and brown-out detection circuitry that triggers reset below 4.25 V to prevent erratic behavior during power transients.
