Product details
Overview
C161OL25MHABXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller in the C166 family, featuring a 4-stage pipeline CPU, 25 MHz max operating frequency, 2 KB on-chip IRAM, and dual serial channels (asynchronous/synchronous). It supports 80-pin MQFP packaging, 63 general-purpose I/O lines, and operates from 4.5–5.5 V supply. Used in industrial motor control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the C161OL25MHABXUMA1 datasheet, C161OL25MHABXUMA1 pinout, C161OL25MHABXUMA1 application, or C161OL25MHABXUMA1 equivalent, key selection criteria include its 25 MHz timing granularity (2 ns), PEC-driven single-cycle data transfers, 16-priority interrupt system with 40 ns sample rate, and bootstrap loader support for field firmware updates.
Technical Context
The C161OL25MHABXUMA1 implements a register-based 16-bit CPU with single-cycle context switching, enabling rapid task switching in real-time OS environments. Its Peripheral Event Controller (PEC) provides eight interrupt-driven DMA channels for zero-CPU-overhead peripheral-to-memory transfers.
It integrates two multi-functional timer units (5 timers total), two serial interfaces (including high-speed synchronous mode), and programmable chip-select logic supporting up to 4 MB external memory space with configurable bus width (8/16-bit) and multiplexing mode.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C167CR-LM | Higher 66 MHz CPU clock, 8 KB IRAM, enhanced MAC unit - no bootstrap loader ROM | Requires external programming interface; better suited for compute-intensive DSP tasks | Select when >12.5 MIPS throughput or hardware multiply-accumulate is required |
| XMC4500-F100F512 | 32-bit ARM Cortex-M4F, 144 MHz, 512 KB Flash, integrated EtherCAT - no native 5 V I/O | Requires level-shifting for legacy 5 V peripherals; targets modern industrial Ethernet networks | Select for new designs needing Ethernet connectivity, floating-point math, or future-proof scalability |
Compared with C161OL25MHABXUMA1, the C167CR-LM delivers higher computational throughput but lacks field-upgradable firmware capability, while the XMC4500 offers modern architecture and connectivity at the cost of 5 V compatibility and increased BOM complexity.

FAQ
What is the maximum operating temperature range for C161OL25MHABXUMA1?
The C161OL25MHABXUMA1 is rated for industrial temperature operation from –40 °C to +85 °C, verified per Infineon's qualification standards for MQFP-packaged devices. This range supports deployment in control cabinets, motor drives, and outdoor industrial enclosures without forced cooling.
Does C161OL25MHABXUMA1 support in-system programming (ISP)?
No - C161OL25MHABXUMA1 does not support ISP. It features a mask-ROM-based bootstrap loader that enables serial firmware updates after initial programming, but the main application code resides in external Flash or EPROM accessed via its parallel bus interface.
Can C161OL25MHABXUMA1 operate from a 3.3 V supply?
No - C161OL25MHABXUMA1 is specified only for 4.5–5.5 V operation. For 3.3 V designs, Infineon's SAF-C161O-LM3V variant (20 MHz, 3.0–3.6 V) is the functionally equivalent option with identical pinout and peripheral set.
Is there hardware support for CAN bus communication on this microcontroller?
No - C161OL25MHABXUMA1 does not integrate a CAN controller or transceiver. Its two serial channels support UART and synchronous protocols only. CAN functionality requires external CAN controller ICs (e.g., MCP2515) interfaced via SPI or parallel bus.
