Infineon Technologies XC886C6FFA5VACKXUMA1

Overview

XC886C6FFA5VACKXUMA1 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 in two clock cycles. 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 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 XC886C6FFA5VACKXUMA1 datasheet, XC886C6FFA5VACKXUMA1 pinout, XC886C6FFA5VACKXUMA1 application, or XC886C6FFA5VACKXUMA1 equivalent, key selection criteria include Flash size (24 KB), MultiCAN interface support, 10-bit ADC resolution with 8 channels, CCU6 timer for motor control, and dual-supply I/O flexibility in automotive body electronics and industrial control designs.

Technical Context

The XC886C6FFA5VACKXUMA1 implements a two-cycle-per-instruction XC800 core derived from the 8051 architecture, enabling zero-wait-state memory access. Its memory subsystem includes protected 24 KB Flash, 12 KB Boot ROM, and segmented RAM/XRAM with address extension via mapping and paging.

It features a dedicated MultiCAN controller supporting up to 64 message objects and full CAN 2.0B compliance, alongside a CCU6 unit optimized for 3-phase motor control with center-aligned PWM, dead-time insertion, and emergency shutdown. The integrated 10-bit ADC supports configurable conversion sequences and hardware-triggered sampling synchronized to CCU6 events.

FAQ

Does XC886C6FFA5VACKXUMA1 support CAN FD?

No. XC886C6FFA5VACKXUMA1 implements MultiCAN compliant with ISO 11898-1:2003 (Classical CAN 2.0B only), supporting up to 1 Mbit/s with 64 message objects. It lacks CAN FD framing, bit-rate switching, and extended data length capabilities found in later Infineon families like XMC4000 or AURIX.

What is the maximum operating frequency of the XC800 core?

The XC800 core operates at up to 26.67 MHz system clock derived from the PLL, which accepts input frequencies from 1 MHz to 20 MHz via XTAL1. At 26.67 MHz, instruction throughput reaches 13.33 MIPS due to the two-clock-cycle per instruction architecture.

Is the 12 KB Boot ROM accessible for user code storage?

No. The 12 KB Boot ROM is factory-programmed with a certified bootloader and diagnostic routines, and is read-only with no write or erase capability. User application code must reside in the 24 KB Flash memory, which supports in-system programming and sector protection.

Can Port 0 be used as general-purpose I/O without external pull-ups?

Yes, but only in quasi-bidirectional mode with internal weak pull-ups enabled. Unlike standard 8051 ports, Port 0 does not require external pull-ups for basic digital I/O; however, external pull-ups are mandatory when Port 0 functions as address/data bus during external memory access.
