Product details
Overview
XC886CM8FFI5VACFXUMA1 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 24 KB Flash memory, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with dual-voltage I/O (3.3 V or 5.0 V) and a 2.5 V core supplied by an embedded voltage regulator. It supports CAN 2.0B via MultiCAN, 10-bit 8-channel ADC, and LIN protocol - deployed in automotive body control modules requiring deterministic real-time response.
For engineers reviewing the XC886CM8FFI5VACFXUMA1 datasheet, XC886CM8FFI5VACFXUMA1 pinout, XC886CM8FFI5VACFXUMA1 application, or XC886CM8FFI5VACFXUMA1 equivalent, key selection considerations include its integrated MultiCAN controller with message object handling, on-chip debug support via JTAG/OCDS, flash memory protection scheme with password register, and dual-supply I/O compatibility for mixed-voltage system interfacing.
Technical Context
The XC886CM8FFI5VACFXUMA1 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 acceleration. Its memory architecture separates code (Flash/ROM), data (RAM/XRAM), and boot space, with configurable memory protection enforced via dedicated SFRs and password-protected write access.
Real-time peripherals include Timer 0/1/2/21 (16-bit), CCU6 (16-bit capture/compare unit), UART/UART1 with LIN header detection, SSC synchronous serial interface, and MultiCAN with 16 message objects and programmable acceptance filtering. The ADC supports configurable conversion sequences with up to 8 input channels and 10-bit resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | XC800 (8051-compatible), 2-clock/machine cycle → enables zero-wait-state execution from internal Flash/ROM. |
| Flash Memory | 24 KB Flash + 12 KB Boot ROM → supports secure boot and field firmware updates without external storage. |
| RAM | 256 B on-chip RAM + 1.5 KB XRAM → sufficient for real-time task stacks and CAN message buffering in automotive nodes. |
| ADC | 10-bit, 8-channel SAR ADC with configurable sequence control → enables simultaneous sensor monitoring (e.g., temperature, voltage, potentiometer). |
| MultiCAN Interface | CAN 2.0B compliant with 16 message objects, hardware acceptance filtering, and automatic retransmission → reduces CPU load in distributed vehicle networks. |
| Supply Architecture | Dual supply: I/O at 3.3 V or 5.0 V, core at 2.5 V (internally regulated) → simplifies board-level power design and ensures noise immunity for analog/digital coexistence. |
| Debug Support | On-chip debug via JTAG and OCDS → enables non-intrusive real-time tracing and breakpoint debugging without external emulator hardware. |
Pinout & Package
XC886CM8FFI5VACFXUMA1 is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad, qualified for industrial temperature range (–40 °C to +125 °C) and AEC-Q100 Grade 2 compliance per Infineon documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP0–VDDP3 | I/O Power Supply (3.3 V or 5.0 V) | Four independent I/O supply domains allow mixed-voltage peripheral interfacing (e.g., 5 V sensors + 3.3 V transceivers). |
| VDD | Core Logic Supply (2.5 V) | Internally regulated from VDDP; decoupling required to maintain stable core voltage under dynamic MCU load. |
| XTAL1/XTAL2 | External Crystal Oscillator Input/Output | Supports 1–20 MHz crystal; internal oscillator can be bypassed for precision timing in CAN/LIN applications. |
| CANRX/CANTX | MultiCAN Physical Layer Interface | Dedicated differential-capable pins with internal pull-ups; require external CAN transceiver for bus connection. |
| ADCTRIG/ADCSYNC | ADC Trigger & Synchronization Input | Enables hardware-synchronized sampling across multiple channels using timer or external event. |
| TMS/TCK/TDO/TDI | JTAG Debug Interface | Full IEEE 1149.1-compliant boundary scan and debug access; no additional debug probe required. |
Key Features
| Feature | Design Value |
|---|---|
| Memory Protection Strategy | Password-protected Flash write/erase and ROM lock bits prevent unauthorized firmware modification or cloning in production ECUs. |
| MultiCAN with Message Objects | 16 dedicated message objects with individual ID masking and priority arbitration eliminate software polling overhead in multi-node CAN networks. |
| LIN Protocol Support | Hardware-assisted LIN header detection and synchronization reduce CPU usage below 5% during frame transmission in body electronics gateways. |
| CORDIC Coprocessor | Accelerates sine/cosine/arctan calculations in <10 µs → enables real-time motor angle estimation without floating-point library overhead. |
| Embedded Voltage Regulator | Generates stable 2.5 V core supply from I/O rail → eliminates need for external LDO and reduces BOM count in space-constrained modules. |
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 |
|---|---|---|---|
| XC878CM8FFI5VACFXUMA1 | Same XC800 core, but with 32 KB Flash, enhanced CCU6 with dead-time insertion, and extended temperature range (–40 °C to +150 °C). | Better suited for high-temperature engine control units where extended thermal margin is required. | Select when >24 KB Flash or higher ambient operating temperature is mandatory; pinout and peripheral register map are identical. |
| S9S08DZ128F1MLH | Freescale S08 core (not 8051-compatible), 128 KB Flash, 8 KB RAM, but lacks CORDIC and MDU; CAN 2.0A only (no 2.0B extended frames). | Requires full toolchain and firmware rewrite; suitable for new designs prioritizing memory headroom over legacy 8051 code reuse. | Choose only for greenfield projects where 8051 compatibility is not required and larger Flash is critical. |
Compared with XC886CM8FFI5VACFXUMA1, XC878 offers direct upgrade path with identical footprint and software compatibility, while S9S08DZ128 demands architectural rework but provides greater memory scalability for complex control algorithms.

FAQ
Does XC886CM8FFI5VACFXUMA1 support CAN FD?
No. The MultiCAN module in this device implements CAN 2.0B only, supporting standard and extended identifiers with bit rates up to 1 Mbps. CAN FD features such as flexible data rate and larger payload are absent; it is not electrically or protocol-compatible with CAN FD transceivers.
What is the maximum ADC sampling rate achievable?
The ADC achieves up to 100 kSPS under optimal conditions: 10-bit resolution, internal clock derived from system clock divided by 4, and single-channel continuous mode. Conversion time is 11.5 µs per sample, limited by internal capacitor settling and reference stability.
Is the Boot ROM field-programmable or fixed content?
The 12 KB Boot ROM contains factory-programmed, immutable firmware including bootloader, flash programming routines, and communication stacks (LIN/CAN). It cannot be erased or rewritten; however, its execution can be enabled or bypassed via BOOT bit in SYSCON register.
Can the embedded voltage regulator power external circuitry?
No. The internal 2.5 V regulator supplies only the core logic and is not rated for external loading. Its output is not accessible on any pin; external circuits must use dedicated regulators or LDOs powered from VDDP rails.
