Product details
Overview
XC878M16FFI5VACFXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the standard 8051 instruction set and executing instructions at two clocks per machine cycle. It integrates 52 KB Flash, 256 B RAM, 3 KB XRAM, and a 10-bit 8-channel ADC. The device operates with I/O supply at 5.0 V and core logic at 2.5 V via an embedded voltage regulator, targeting automotive body electronics and industrial control.
For engineers reviewing the XC878M16FFI5VACFXUMA1 datasheet, XC878M16FFI5VACFXUMA1 pinout, XC878M16FFI5VACFXUMA1 application, or XC878M16FFI5VACFXUMA1 equivalent, key selection criteria include its dual-voltage I/O architecture, MultiCAN interface, CCU6 timer unit for motor control, LIN protocol support, and on-chip debug via JTAG.
Technical Context
The XC878M16FFI5VACFXUMA1 implements the XC800 core with two data pointers and zero-wait-state memory access enabled by its two-clock-per-cycle execution. Its memory subsystem includes 52 KB Flash with hardware-based protection, 256 B internal RAM, and 3 KB XRAM mapped into the external data space.
Peripheral integration centers on real-time control: a 16-bit CCU6 unit with capture/compare and PWM generation, MultiCAN 2.0B controller supporting up to 16 message objects, LIN 2.1 master/slave capability, and a 10-bit ADC with configurable conversion sequencing and hardware trigger synchronization to timers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC886CM-13FRAA | Same XC800 core but with 64 KB Flash, enhanced CAN FD support, and higher max CPU frequency (40 MHz). | Targets next-gen automotive ECUs requiring CAN FD bandwidth and larger firmware footprint. | Select when future-proofing against CAN FD migration or needing >52 KB code space. |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB Flash, dual CAN, but no LIN or CCU6; requires external 3.3 V regulator. | Suitable for higher-complexity engine management or transmission control where 8-bit throughput is insufficient. | Choose only if migrating to 32-bit deterministic control and accepting increased BOM cost and layout complexity. |
Compared with SAF-XC886CM-13FRAA, XC878M16FFI5VACFXUMA1 offers lower cost and proven qualification for legacy body electronics, while SPC560B50L5 delivers higher compute headroom at the expense of LIN integration and analog peripheral density.

FAQ
What is the maximum operating frequency of the XC878M16FFI5VACFXUMA1?
The device supports a maximum CPU clock frequency of 26.67 MHz, achieved via internal PLL multiplication of an external crystal (e.g., 13.33 MHz input). This frequency is validated under specified operating conditions (VDD = 5.0 V ±10%, TA = –40°C to +125°C) and enables deterministic real-time response for motor control loops and CAN message scheduling.
Does the XC878M16FFI5VACFXUMA1 support CAN FD?
No, it implements MultiCAN 2.0B only, supporting classical CAN frames with up to 8 bytes payload and bit rates up to 1 Mbps. CAN FD capability was introduced in later XC800 derivatives like the XC886; this part lacks the required protocol controller enhancements and arbitration field extensions.
How is Flash memory protected against unauthorized access or overwrite?
Protection is implemented via hardware lock bits in the Flash register set: Boot ROM lock prevents modification of startup code; Flash sector lock bits disable erase/write operations per 2 KB block; and password-based access control restricts debug interface access to protected memory regions.
Can the 10-bit ADC operate synchronously with PWM signals for motor current sampling?
Yes-the ADC supports hardware triggering from CCU6 events (e.g., PWM center-aligned zero-crossing), enabling precise current sampling at optimal commutation points. Conversion results are stored in dedicated result registers and can generate interrupts or DMA requests without CPU intervention.
