Infineon Technologies XC886C6FFI5VACFXUMA1

Overview

XC886C6FFI5VACFXUMA1 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 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 supply generated by an embedded voltage regulator. It supports LIN communication, MultiCAN, 10-bit 8-channel ADC, and CCU6 for motor control in automotive body electronics.

For engineers reviewing the XC886C6FFI5VACFXUMA1 datasheet, XC886C6FFI5VACFXUMA1 pinout, XC886C6FFI5VACFXUMA1 application, or XC886C6FFI5VACFXUMA1 equivalent, key selection considerations include its LIN-capable UART1, integrated 16-bit CCU6 timer for PWM generation, 10-bit ADC with 8 input channels, and dual-supply I/O flexibility for mixed-voltage system interfacing.

Technical Context

The XC886C6FFI5VACFXUMA1 implements the XC800 architecture - a derivative of the 8051 core optimized for real-time control, featuring two data pointers and no wait states for internal memory access. Its clock generation unit supports both external crystal (up to 20 MHz) and internal RC oscillator, with PLL-based frequency multiplication enabling up to 26.67 MHz CPU operation.

It integrates dedicated peripherals for automotive subsystems: a LIN 2.1-compliant UART1 with automatic baud-rate detection, a MultiCAN controller supporting two CAN nodes, and a Capture/Compare Unit 6 (CCU6) with three independent 16-bit timers and dead-time insertion for three-phase motor drive timing control.

Key Specifications

Pinout & Package

XC886C6FFI5VACFXUMA1 is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across six bidirectional I/O ports (Port 0–Port 5), each supporting multiple alternate functions including analog inputs, CAN transceiver lines, LIN bus interface, and CCU6 PWM outputs.

FAQ

Does XC886C6FFI5VACFXUMA1 support CAN FD?

No. The MultiCAN module in this device supports Classical CAN (ISO 11898-1) only, with bit rates up to 1 Mbps. It lacks CAN FD frame format handling, arbitration bit rate extension, and flexible data phase support - features introduced in later Infineon families like the Aurix TC2xx series.

What is the maximum operating frequency of the CPU core?

The XC800 core operates at up to 26.67 MHz, achieved by configuring the on-chip PLL to multiply a 10 MHz external crystal input by 2.667×. This frequency is specified under full industrial temperature range (−40 °C to +125 °C) and 5.0 V supply conditions.

Can the Boot ROM be used to execute user code?

No. The 12 KB Boot ROM contains factory-programmed startup routines and bootloader code only. It is mapped to fixed address space (0x0000–0x2FFF) and cannot be overwritten or reprogrammed. User application code must reside in Flash memory starting at 0x3000.

Is there hardware support for AES or cryptographic operations?

No. XC886C6FFI5VACFXUMA1 does not include dedicated cryptographic accelerators or secure key storage. Security relies on Flash memory protection bits and Boot ROM lockdown - sufficient for basic anti-tampering but not compliant with EVITA Medium or ISO/SAE 21434 hardware security requirements.
