Infineon Technologies SAF-XC886CM-6FFI 5V AC

Overview

SAF-XC886CM-6FFI 5V AC 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 24 KB Flash memory, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with I/O ports rated for 5 V operation and an embedded voltage regulator supplying 2.5 V to the core. It supports CAN 2.0B (MultiCAN), LIN, UART, SSC, 10-bit 8-channel ADC, and CCU6 for motor control - deployed in automotive body electronics and industrial motor drives.

For engineers reviewing the SAF-XC886CM-6FFI 5V AC datasheet, SAF-XC886CM-6FFI 5V AC pinout, SAF-XC886CM-6FFI 5V AC application, or SAF-XC886CM-6FFI 5V AC equivalent, key selection criteria include its 5 V-tolerant I/O capability, integrated MultiCAN controller with message objects, on-chip LIN physical layer support, 16-bit CCU6 for PWM generation, and flash-based field-upgradability in constrained embedded environments.

Technical Context

The XC886CM 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 (24 KB) with sector protection, 12 KB mask-programmed Boot ROM, and separate XRAM for high-speed data access.

Peripheral integration centers on real-time control: MultiCAN with 16 message objects and dedicated transmit/receive buffers; CCU6 with three independent 16-bit timers and dead-time insertion for 3-phase motor gate drive; and a 10-bit SAR ADC with configurable conversion sequence and hardware trigger linkage to CCU6 or timers.

Key Specifications

Pinout & Package

SAF-XC886CM-6FFI 5V AC 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 port groups (P0–P5), each supporting multiple alternate functions including CAN TX/RX, LIN, UART, SSC, CCU6 outputs, ADC inputs, and external interrupt sources.

FAQ

Does SAF-XC886CM-6FFI 5V AC support CAN FD?

No. This device implements MultiCAN compliant with ISO 11898-1:2003 (Classical CAN 2.0B only), supporting bit rates up to 1 Mbps and 16 message objects. CAN FD functionality requires a different silicon family such as the Aurix TC2xx or SAK-TC375.

What is the maximum operating frequency of the XC800 core?

The XC800 core runs at up to 26.7 MHz system clock, derived from an internal PLL that multiplies a 1–20 MHz external crystal or RC oscillator. At this frequency, instruction throughput reaches 13.35 MIPS due to the two-clock-per-cycle architecture.

Is the Boot ROM accessible for user code execution?

Yes - the 12 KB Boot ROM is memory-mapped at address 0x0000 and can be executed directly. It contains factory-programmed startup routines and optional bootloader code, and remains readable even when Flash protection is enabled.

Can Port 0 pins be used simultaneously as address/data bus and CANL?

No - P0.0–P0.7 operate in one mode at a time: either as multiplexed AD0–AD7 during external memory access, or as general-purpose I/O/CANL. The CANL function is only active when the CAN module is enabled and the port is configured for alternate function mode.
