Product details
Overview
XC878CM16FFI5VACFXUMA1 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 features MultiCAN, UART1, SSC, CCU6, and CORDIC coprocessor, and targets automotive body electronics and industrial motor control.
For engineers reviewing the XC878CM16FFI5VACFXUMA1 datasheet, XC878CM16FFI5VACFXUMA1 pinout, XC878CM16FFI5VACFXUMA1 application, or XC878CM16FFI5VACFXUMA1 equivalent, key selection criteria include its 52 KB protected Flash memory, dual-voltage I/O (5 V tolerant), embedded 2.5 V core regulator, and integrated CAN 2.0B controller with message object handling.
Technical Context
The XC878CM16FFI5VACFXUMA1 implements an enhanced 8051-compatible CPU core with two data pointers and zero-wait-state memory access via its two-clock-per-cycle architecture. It supports memory protection through flash bank locking and bit-level password-protected register access.
Its peripheral set includes a 16-bit CCU6 for PWM generation in motor control, a 16-bit Timer 21 for precise timing, and a MultiCAN module supporting up to 64 message objects with hardware filtering and transmit prioritization - all operating under a unified clock system derived from either internal RC oscillator or external crystal (1–20 MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | XC800 (8051-compatible), 2-clock/machine cycle → enables full-speed execution without wait states on internal memory |
| Flash Memory | 52 KB with memory protection → supports secure firmware storage and field updates with lockable sectors |
| RAM / XRAM | 256 B on-chip RAM + 3 KB XRAM → sufficient for real-time control stacks and buffered communication data |
| ADC | 10-bit, 8-channel, programmable sampling rate → suitable for analog sensor interfacing in motor current/voltage monitoring |
| MultiCAN Interface | CAN 2.0B compliant, 64 message objects, hardware acceptance filtering → reduces CPU load in automotive networked systems |
| Supply Architecture | Dual supply: I/O at 5 V (tolerant), core at 2.5 V (internally regulated) → simplifies board power design while maintaining noise immunity |
| Clock Source | Internal 12 MHz RC oscillator ±10% or external 1–20 MHz crystal → enables flexible timing accuracy vs. cost trade-offs |
Pinout & Package
XC878CM16FFI5VACFXUMA1 is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad, rated for industrial temperature range (–40 °C to +125 °C) and AEC-Q100 Grade 2 qualification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.7 | Port 0 bidirectional I/O / AD0–AD7 multiplexed | 8-bit quasi-bidirectional port; functions as lower address/data bus during external memory access |
| P1.0–P1.7 | Port 1 general-purpose I/O / CANRX0/CANTX0 | Dedicated CAN0 transceiver interface pins; configurable as GPIO when CAN unused |
| P3.0–P3.7 | Port 3 general-purpose I/O / UART1 RX/TX, SSC CLK/MOSI/MISO | Shared serial peripheral signals; enables compact LIN/CAN/SSC coexistence without external muxing |
| XTAL1/XTAL2 | External crystal oscillator input/output | Supports fundamental-mode crystals up to 20 MHz; internal feedback resistor enables minimal external component count |
| VDDP/VSSP | I/O power supply (5 V) and ground | Separate I/O rail allows direct interfacing with 5 V sensors, actuators, and legacy automotive modules |
| VDDC/VSSC | Core logic supply (2.5 V) and ground | Internally generated from VDDP via embedded LDO → eliminates need for external core regulator |
Key Features
| Feature | Design Value |
|---|---|
| CORDIC Coprocessor | Hardware-accelerated sine/cosine/arctan computation → enables real-time vector control in BLDC/PMSM motor drives without floating-point library overhead |
| CCU6 PWM Unit | Three independent 16-bit capture/compare channels with dead-time insertion → supports three-phase inverter gate driving with fault-safe shutdown |
| On-Chip Debug (OCDS) | JTAG-based real-time debugging with hardware breakpoints and trace → reduces development cycle time for safety-critical automotive firmware |
| Flash Protection | Password-locked sector write/erase and read-protection → prevents unauthorized firmware extraction or modification in production ECUs |
| LIN Master Support | Built-in LIN 2.1 header generation and checksum calculation → eliminates need for external LIN transceiver in slave-node applications |

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-16FRAA | 64 KB Flash, 32 KB RAM, enhanced CAN FD support, 40 MHz max CPU frequency | Targets next-gen ECU designs requiring higher bandwidth CAN FD and larger code footprint | Select when migrating from legacy CAN to CAN FD or requiring >52 KB Flash for complex diagnostics |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB Flash, ASIL-B capable, no CORDIC or CCU6 | Suitable for safety-critical powertrain applications requiring ISO 26262 compliance | Choose only if functional safety certification (ASIL-B) is mandatory and 8-bit performance is insufficient |
Compared with SAF-XC886CM-16FRAA and SPC560B50L5, XC878CM16FFI5VACFXUMA1 delivers optimal cost-performance balance for non-safety-critical automotive body applications where CORDIC-assisted motor control and mature 8-bit toolchain support are essential.

FAQ
Is XC878CM16FFI5VACFXUMA1 qualified for automotive use?
Yes. This part carries AEC-Q100 Grade 2 qualification (–40 °C to +125 °C ambient), is manufactured in Infineon's certified automotive wafer fabs, and includes built-in self-test features such as flash CRC checking and oscillator fail-detection circuitry required for automotive ECUs.
Does it support in-system programming via CAN or UART?
Yes. The device supports bootloader operation via UART1 or CAN, allowing firmware updates without JTAG. The integrated boot ROM contains a validated flash programming routine that verifies checksums before committing new code to protected sectors.
What debug interfaces are available?
XC878CM16FFI5VACFXUMA1 supports OCDS (On-Chip Debug Support) via standard JTAG interface (TCK/TMS/TDI/TDO/TRST), enabling real-time variable inspection, hardware breakpoints, and trace buffer capture using Infineon's DAS-USB or third-party compatible debug probes.
Can the internal voltage regulator power external circuitry?
No. The embedded 2.5 V regulator supplies only the core logic and internal peripherals. It is not rated for external load driving. External circuits must be powered separately; the I/O supply (VDDP) remains at 5 V and is intended for interfacing with external 5 V devices.
