Infineon Technologies XC886CLM8FFA5VACKXUMA1

Overview

XC886CLM8FFA5VACKXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the 8051 instruction set and executing instructions at two clocks per machine cycle. It integrates 24 KB Flash, 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 2.5 V core supply via embedded regulator. It supports CAN 2.0B (MultiCAN), LIN, UART, SSC, 10-bit 8-channel ADC, CCU6, and on-chip debug via JTAG.

For engineers reviewing the XC886CLM8FFA5VACKXUMA1 datasheet, XC886CLM8FFA5VACKXUMA1 pinout, XC886CLM8FFA5VACKXUMA1 application, or XC886CLM8FFA5VACKXUMA1 equivalent, key selection considerations include its integrated MultiCAN controller, LIN protocol support, flash-based reprogrammability, 10-bit ADC resolution with 8 input channels, and dual-supply I/O flexibility for mixed-voltage system interfacing.

Technical Context

The XC886CLM8FFA5VACKXUMA1 implements a pipelined 8051-compatible CPU core with two-clock-per-cycle execution, eliminating wait states for internal memory access. Its memory protection strategy includes Flash write/erase lock bits and password-protected register access to prevent unauthorized firmware modification.

It features a dedicated MultiCAN module supporting up to 64 message objects, full CAN 2.0B compliance, and hardware timestamping; plus a LIN 2.1-compliant interface with automatic baud rate detection and header transmission control - both optimized for automotive body electronics and distributed control nodes.

FAQ

What is the maximum operating frequency of the XC886CLM8FFA5VACKXUMA1?

The device supports an external crystal or clock input up to 20 MHz, and its XC800 core executes instructions at two clocks per machine cycle - delivering effective throughput of approximately 10 MIPS at 20 MHz. The on-chip oscillator and PLL allow flexible clock tree configuration, including frequency multiplication for peripheral domains.

Does the XC886CLM8FFA5VACKXUMA1 support in-system programming (ISP)?

Yes, it supports ISP via UART or JTAG using the on-chip bootloader located in the 12 KB Boot ROM. Firmware updates can be performed without removing the device from the PCB, provided the application reserves appropriate Flash sectors and configures OCDS security settings to permit reprogramming.

How many CAN message objects does the MultiCAN module support?

The MultiCAN module supports up to 64 message objects, each configurable as transmit or receive buffers with individual identifier masking, priority levels, and hardware timestamping. This enables efficient handling of multiple CAN IDs and simultaneous communication on multiple CAN buses when used with external transceivers.

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 configurable conversion sequences (up to 8 steps) and trigger sources (software, timer, or external event), but does not perform true simultaneous sampling. However, its minimum conversion time of 1.5 µs per channel allows rapid interleaved acquisition suitable for motor current and voltage monitoring.
