Infineon Technologies SAF-XC886-8FFA 5V AC

Overview

SAF-XC886-8FFA 5V AC from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the 8051 instruction set and executing instructions in two clock cycles. It integrates 24 KB Flash, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with dual-voltage I/O (5 V) and core logic (2.5 V via embedded regulator). It supports LIN, MultiCAN, 10-bit 8-channel ADC, and CCU6 for motor control - deployed in automotive body electronics and industrial motor drives.

For engineers reviewing the SAF-XC886-8FFA 5V AC datasheet, SAF-XC886-8FFA 5V AC pinout, SAF-XC886-8FFA 5V AC application, or SAF-XC886-8FFA 5V AC equivalent, key selection factors include its 5 V-tolerant I/O ports, integrated LIN transceiver support, MultiCAN 2.0B compliance, on-chip voltage regulator enabling single-supply operation, and CCU6 timer for precise PWM generation in BLDC motor control.

Technical Context

The XC886 implements a two-cycle-per-instruction 8051-compatible CPU with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory architecture separates code (Flash/ROM), data (RAM/XRAM), and boot space, with configurable protection via password registers and sector locking.

Peripheral integration includes a 16-bit CCU6 unit with capture/compare channels for 3-phase motor timing, a 10-bit SAR ADC with 8 input channels and programmable sampling, and a MultiCAN controller supporting up to 64 message objects with full CAN 2.0B protocol handling - all synchronized to a PLL-stabilized clock derived from internal oscillator or external crystal.

FAQ

Does SAF-XC886-8FFA 5V AC support CAN FD?

No. The device integrates a MultiCAN 2.0B controller compliant with ISO 11898-1:2003, supporting bit rates up to 1 Mbps and 64 message objects. CAN FD functionality requires separate 32-bit controllers like Infineon's TC3xx series and is not implemented in the XC800 architecture.

What is the maximum operating frequency of the XC800 core?

The XC800 core runs at up to 26.67 MHz under standard conditions, achieved via PLL multiplication of the internal 1.5 MHz oscillator or external crystal input. At this frequency, instruction throughput reaches 13.33 MIPS due to the two-clock-cycle execution architecture.

Can the embedded voltage regulator be bypassed for external core supply?

No. VDDC must be supplied through the internal regulator powered by VDDP; the datasheet prohibits direct external connection to VDDC pins. The regulator is non-bypassable and designed to deliver stable 2.5 V ±5% to the core logic domain from 4.5–5.5 V VDDP input.

Is there hardware support for LIN checksum calculation?

Yes. UART1 includes dedicated LIN header detection and automatic checksum generation for both classic and enhanced checksum modes (LSB-first, 8-bit sum, or 2's complement), executed in hardware without CPU intervention during frame transmission.
