Product details
Overview
80C166MT3DDBXUMA1 from Infineon is a 16-bit C166 microcontroller with 256 KB on-chip ROM, 16 KB RAM, and a 25 MHz CPU clock. It integrates a 10-bit ADC, six capture/compare units, and a watchdog timer. It targets real-time industrial control systems requiring deterministic interrupt response and embedded motor sequencing.
For engineers reviewing the 80C166MT3DDBXUMA1 datasheet, 80C166MT3DDBXUMA1 pinout, 80C166MT3DDBXUMA1 application, or 80C166MT3DDBXUMA1 equivalent, key selection criteria include ROM/RAM size, ADC resolution and channel count, timer architecture, and industrial temperature range support (–40 °C to +85 °C).
Technical Context
The 80C166MT3DDBXUMA1 implements the C166 V2 core with instruction set compatibility to earlier C167 devices. It supports memory-mapped I/O, vectored interrupts with priority encoding, and a peripheral event controller (PEC) for autonomous DMA-like data transfers without CPU intervention.
Its on-chip peripherals include a synchronous serial interface (SSI), UART with automatic baud rate detection, and a general-purpose I/O port with configurable pull-up/pull-down and Schmitt-trigger inputs. The device uses a single 5 V supply and features power-down modes controlled via the system configuration register.

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 |
|---|---|---|---|
| C167CR-LM | Same C166 V2 core but with 512 KB ROM, no on-chip RAM (requires external), and extended temperature range (–40 °C to +125 °C) | Targeted at higher-reliability automotive powertrain modules where extended temp and larger firmware footprint are critical | Select when firmware exceeds 256 KB or ambient operating temperature exceeds +85 °C |
| XC164CS-32F40F | Enhanced C166 derivative with 32 KB RAM, 40 MHz CPU, and CAN 2.0B controller - lacks on-chip ROM (uses external flash) | Designed for networked industrial nodes requiring CAN bus integration and faster control loop execution | Select when CAN communication or sub-1 µs interrupt latency is mandatory, and external flash is acceptable |
Compared with C167CR-LM and XC164CS-32F40F, the 80C166MT3DDBXUMA1 offers optimal balance of on-chip memory integration, deterministic real-time performance, and cost-effective 5 V operation - ideal for self-contained, non-networked industrial controllers where external memory or CAN are unnecessary.

FAQ
Is the 80C166MT3DDBXUMA1 pin-compatible with other C166-series microcontrollers?
No. While it shares the C166 V2 core architecture with devices like the C167CR-LM, the 80C166MT3DDBXUMA1 uses a unique 100-pin LQFP package with specific pin assignments for its 256 KB ROM and 16 KB RAM configuration. Pin mappings for address/data bus, peripheral functions, and JTAG differ from later derivatives such as the XC164 series, which added CAN and modified power management pins.
Does the 80C166MT3DDBXUMA1 support in-system programming (ISP)?
No. The 80C166MT3DDBXUMA1 contains mask-programmed ROM, meaning firmware is permanently embedded during fabrication. It does not support ISP or flash reprogramming. Firmware updates require replacement of the physical device. Debugging and development rely on JTAG-based emulation using tools like Infineon's DAS500 or third-party ICE adapters.
What is the maximum achievable ADC sampling rate on this device?
The integrated 10-bit ADC achieves up to 100 kSPS under optimal conditions: single-channel conversion with minimum acquisition time, no PEC overhead, and CPU not accessing shared bus resources. With 8 channels scanned sequentially and PEC enabled, sustained throughput drops to ~12.5 kSPS per channel due to bus arbitration and conversion setup overhead.
Can the 80C166MT3DDBXUMA1 operate from a 3.3 V supply?
No. The device is specified only for 5.0 V ±10% operation. Its I/O structure, internal regulators, and flash programming voltage requirements are incompatible with 3.3 V logic levels. Interfacing with 3.3 V peripherals requires level-shifting circuitry on all bidirectional or input-only signals, including address/data bus and UART lines.
