Product details
Overview
XC886CLM8FFAACAXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core (8051-compatible), featuring 32 KB Flash, 256 B RAM, 1.5 KB XRAM, and integrated peripherals including 10-bit 8-channel ADC, MultiCAN, UART1, SSC, CCU6, and CORDIC coprocessor. It operates with dual-supply architecture: I/O ports at 5.0 V and core logic at 2.5 V via embedded voltage regulator, targeting automotive body electronics and industrial control.
For engineers reviewing the XC886CLM8FFAACAXUMA1 datasheet, XC886CLM8FFAACAXUMA1 pinout, XC886CLM8FFAACAXUMA1 application, or XC886CLM8FFAACAXUMA1 equivalent, key selection criteria include Flash size (32 KB), dual-voltage operation (5 V I/O / 2.5 V core), CAN 2.0B compliance, CORDIC acceleration for motor control math, and JTAG-based on-chip debug support.
Technical Context
The XC886CLM8FFAACAXUMA1 implements a two-clock-per-machine-cycle 8051-compatible CPU core, enabling zero-wait-state memory access. It integrates a 16-bit Capture/Compare Unit (CCU6) for precise PWM generation and a dedicated CORDIC coprocessor for real-time trigonometric and hyperbolic function computation-critical for field-oriented motor control algorithms.
Its clock system supports external crystal (1–20 MHz), RC oscillator, or PLL-derived clocks up to 27 MHz. The MultiCAN module provides two independent CAN nodes compliant with ISO 11898-1:2003, supporting both standard and extended frames with message objects configurable in RAM.
Key Specifications

Pinout & Package
XC886CLM8FFAACAXUMA1 is housed in a 64-pin LQFP package (10 × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across four bidirectional digital I/O ports (P0–P3), plus dedicated analog inputs (AD0–AD7), CANH/CANL, XTAL1/XTAL2, and JTAG debug pins (TCK/TMS/TDI/TDO/TRST).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.7 | Port 0 bidirectional I/O / AD0–AD7 | 8-bit port with analog input capability on all pins; used for ADC channel selection and general-purpose digital I/O. |
| P1.0–P1.7 | Port 1 bidirectional I/O / CCU6 inputs | Supports capture/compare events for motor control timing; includes dedicated CCU6 trigger inputs (CAPREL, CAPIN). |
| P2.0–P2.7 | Port 2 bidirectional I/O / CANH/CANL | Hosts CAN transceiver interface signals; enables direct connection to physical CAN bus without external level-shifting. |
| P3.0–P3.7 | Port 3 bidirectional I/O / UART1/SSC | Configurable for UART1 (TXD1/RXD1), synchronous serial (SCLK/SDI/SDO), or general I/O-supports LIN and SPI-like protocols. |
| XTAL1/XTAL2 | Crystal oscillator input/output | Drives external quartz crystal (1–20 MHz); internal oscillator circuit eliminates need for external clock source in cost-sensitive designs. |
| TCK/TMS/TDI/TDO | JTAG debug interface | Enables full on-chip debugging, flash programming, and boundary scan testing without requiring additional debug hardware. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| XC886CLM4FFAACAXUMA1 | 16 KB Flash (vs. 32 KB), identical peripheral set and pinout. | Suitable for simpler firmware with reduced code footprint; lacks headroom for future feature expansion. | Select when application firmware fits within 16 KB and cost sensitivity outweighs scalability needs. |
| XC886CM8FFAACAXUMA1 | Same 32 KB Flash but lacks CORDIC coprocessor and has reduced CCU6 functionality (no shadow transfer). | Applicable where motor control is limited to basic six-step commutation rather than FOC. | Choose when CORDIC acceleration is unnecessary and lower BOM cost is prioritized over advanced motion control capability. |
Compared with XC886CLM4FFAACAXUMA1 and XC886CM8FFAACAXUMA1, the XC886CLM8FFAACAXUMA1 uniquely delivers full FOC readiness via CORDIC + CCU6 shadow registers, while its 32 KB Flash supports complex diagnostics, bootloader, and OTA update partitions-making it optimal for next-generation automotive and industrial motion systems.

FAQ
Does XC886CLM8FFAACAXUMA1 support CAN FD?
No. The MultiCAN module in this device complies strictly with ISO 11898-1:2003 (Classical CAN 2.0B) and does not implement CAN FD features such as flexible data-rate or extended payload length. It supports only standard (11-bit) and extended (29-bit) identifier frames at up to 1 Mbit/s.
What is the maximum ADC sampling rate achievable?
The 10-bit ADC achieves a maximum conversion rate of 1 MS/s under optimal conditions: single-channel mode, minimum sample-and-hold time, and system clock ≥27 MHz. With 8-channel scanning and automatic sequencing, effective throughput drops to ~125 kS/s due to multiplexer settling and conversion overhead.
Is the embedded voltage regulator adjustable?
No. The internal voltage regulator delivers a fixed 2.5 V output to the core logic domain. It is not user-adjustable and requires a stable 4.5–5.5 V supply on VDDIO (pins 1–8, 57–64) to maintain regulation accuracy and thermal stability across temperature and load variations.
Can the CORDIC unit operate independently of the CPU core?
Yes. The CORDIC coprocessor executes trigonometric and hyperbolic functions autonomously once configured via its control registers. It signals completion via interrupt or flag, allowing the CPU to perform other tasks concurrently-enabling true hardware-accelerated math offload in real-time control loops.
