Product details
Overview
XC888CM8FFA5VACKXUMA1 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 32 KB Flash, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM; features a 10-bit 8-channel ADC, MultiCAN interface, CCU6 capture/compare unit, and embedded 2.5 V voltage regulator for core logic. It targets automotive body electronics and industrial control systems requiring LIN and CAN communication.
For engineers reviewing the XC888CM8FFA5VACKXUMA1 datasheet, XC888CM8FFA5VACKXUMA1 pinout, XC888CM8FFA5VACKXUMA1 application, or XC888CM8FFA5VACKXUMA1 equivalent, key selection considerations include its dual-voltage I/O (3.3 V/5.0 V), on-chip debug support via JTAG, LIN protocol compliance, MultiCAN controller with 64 message objects, and flash memory protection architecture.
Technical Context
The XC888CM8FFA5VACKXUMA1 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 subsystem includes segmented Flash (32 KB) with sector-based protection, 12 KB mask-programmed Boot ROM, and separate XRAM (1.5 KB) accessible via MOVX instructions.
Peripheral integration centers on real-time control: MultiCAN supports up to 64 message objects with transmit/receive FIFOs; CCU6 provides six PWM channels with dead-time insertion; SSC operates in master/slave synchronous serial mode; and Timer 21 delivers high-resolution 16-bit timing with prescaler and capture capability.
Key Specifications

FAQ
Does XC888CM8FFA5VACKXUMA1 support in-application programming (IAP) of Flash memory?
Yes, the device supports IAP via its on-chip bootloader located in protected Boot ROM. Firmware can reprogram Flash sectors using dedicated command sequences and status registers, with write/erase cycles verified by hardware CRC and lock-bit enforcement to prevent accidental corruption.
What is the maximum operating frequency of the XC800 core in this variant?
The XC888CM8FFA5VACKXUMA1 operates at up to 26.67 MHz CPU clock derived from the PLL, corresponding to 13.33 MIPS performance. This frequency is achievable with external crystal (1–20 MHz) or internal oscillator, subject to voltage and temperature conditions specified in Section 4.3.4 of the datasheet.
Can Port 0 be used as a general-purpose I/O without external pull-ups?
No - Port 0 lacks internal pull-ups and functions as an open-drain bus during external memory access. When used as GPIO, external 4.7 kΩ pull-up resistors are required on all P0.x lines to ensure valid logic-high levels and noise immunity in industrial environments.
Is the embedded voltage regulator capable of powering external circuitry?
No - the internal 2.5 V regulator supplies only the core logic and internal peripherals. It is not rated for external load driving; VDDIO must be supplied separately at 3.3 V or 5.0 V to power I/O buffers, external transceivers, or sensors connected to port pins.
