Product details
Overview
XC878CM16FFA5VACKXUMA1 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, 3 KB XRAM, 256 B RAM, and 8 KB Boot ROM, with dual-voltage operation (core at 2.5 V, I/O at 5.0 V), and targets automotive body electronics and industrial motor control applications.
For engineers reviewing the XC878CM16FFA5VACKXUMA1 datasheet, XC878CM16FFA5VACKXUMA1 pinout, XC878CM16FFA5VACKXUMA1 application, or XC878CM16FFA5VACKXUMA1 equivalent, key selection criteria include its integrated MultiCAN interface, 10-bit 8-channel ADC, CCU6 capture/compare unit for motor timing, and on-chip debug support via JTAG.
Technical Context
The XC878CM16FFA5VACKXUMA1 implements a two-clock-per-machine-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory architecture separates 52 KB Flash (with bank pagination and password-protected write/erase) from 3 KB XRAM and 256 B internal RAM, enabling deterministic real-time execution in safety-critical embedded control.
Peripheral integration includes a 16-bit CCU6 unit with dead-time generation and shadow transfer for three-phase motor drive, a 10-bit ADC with configurable conversion sequence and sample-and-hold, and a MultiCAN controller supporting up to 64 message objects with hardware acceptance filtering - all synchronized to a flexible clock system with PLL and multiple power-saving modes.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC886CM-13FRA5VAC | Same XC800 core, 64 KB Flash, added 12-bit ADC and enhanced CAN FD readiness (pin-compatible but requires updated transceiver) | Higher-resolution sensing and future CAN FD migration path; larger Flash for OTA update partitioning | Select when upgrading sensor accuracy or planning CAN FD transition; requires layout revision for transceiver compatibility |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB Flash, ASIL-B certified, no CORDIC/MDU but higher floating-point throughput | Safety-critical applications requiring ISO 26262 compliance; lacks integrated LIN but adds FlexRay/Ethernet options | Select only where functional safety certification is mandatory; significantly higher BOM cost and toolchain complexity |
Compared with SAF-XC886CM-13FRA5VAC and SPC560B50L5, XC878CM16FFA5VACKXUMA1 offers optimal balance of deterministic 8-bit real-time control, integrated motor peripherals, and automotive-qualified 5 V I/O - making it ideal for cost-sensitive, non-ASIL body electronics where CORDIC-assisted vector math is essential.

FAQ
What is the maximum operating frequency of the XC878CM16FFA5VACKXUMA1?
The XC878CM16FFA5VACKXUMA1 achieves a maximum CPU clock of 26.67 MHz using its internal PLL, driven by an external 1–20 MHz crystal connected to XTAL1/XTAL2. This corresponds to 13.33 MIPS performance due to its two-clock-per-instruction-cycle architecture, verified under 5.0 V ±5% supply and ambient temperature range –40°C to +125°C.
Does this microcontroller support in-system programming (ISP) via standard interfaces?
Yes - XC878CM16FFA5VACKXUMA1 supports ISP through its JTAG interface using Infineon's DAS (Debug Access Service) protocol. The on-chip bootloader in 8 KB Boot ROM enables firmware updates without external programming hardware, provided the JTAG TCK/TMS/TDI/TDO and TRST pins are accessible and not multiplexed to conflicting functions.
How many CAN message objects does the MultiCAN module support, and are they configurable?
The MultiCAN module supports exactly 64 message objects, each independently configurable for transmit/receive mode, identifier masking, data length code (0–8 bytes), and acceptance filtering. All objects reside in dedicated RAM with hardware arbitration and priority encoding - no CPU intervention is needed for message handling beyond initialization and status polling.
Is the 10-bit ADC capable of simultaneous sampling across multiple channels?
No - the ADC is a single SAR converter with sequential channel scanning. It supports programmable conversion sequences (up to 16 steps) and automatic channel sequencing triggered by timer or external event, but does not provide true simultaneous sampling. Sample-and-hold is implemented per channel during sequence execution to minimize inter-channel skew.
