Infineon Technologies SAF-XC888-8FFA 5V AC

Overview

SAF-XC888-8FFA 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 in two clock cycles. It integrates 32 KB Flash memory, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with dual-voltage I/O (5 V) and internal 2.5 V core regulation. It supports CAN 2.0B via MultiCAN, 10-bit 8-channel ADC, and LIN protocol - deployed in automotive body control modules requiring real-time sensor interfacing and actuator control.

For engineers reviewing the SAF-XC888-8FFA 5V AC datasheet, SAF-XC888-8FFA 5V AC pinout, SAF-XC888-8FFA 5V AC application, or SAF-XC888-8FFA 5V AC equivalent, key selection criteria include flash size (32 KB), embedded MultiCAN interface, 5 V-tolerant I/O, on-chip voltage regulator, and LIN-compliant UART1 for automotive network integration.

Technical Context

The XC888 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 protection strategy includes Flash write protection and password-protected register access to prevent unauthorized firmware modification.

It features a dedicated MultiCAN controller supporting up to 64 message objects, full CAN 2.0B compliance, and automatic retransmission. The integrated 10-bit ADC operates with programmable sampling time and supports scan mode across eight analog inputs, synchronized with CCU6 timers for motor control timing.

FAQ

Is SAF-XC888-8FFA 5V AC AEC-Q100 qualified?

Yes - SAF-XC888-8FFA 5V AC is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C ambient), with test reports covering HTOL, TC, ESD, and EMC per automotive requirements. Qualification applies to the full 80-pin LQFP package variant with 5 V I/O supply configuration.

Does it support in-system programming via JTAG?

Yes - the device includes full OCDS (On-Chip Debug Support) compliant with Infineon's DAS standard, enabling JTAG-based flash programming, breakpoint debugging, and real-time variable monitoring without boot loader intervention.

What is the maximum operating frequency of the on-chip oscillator?

The internal oscillator supports up to 27 MHz operation with ±2 % short-term deviation at 25 °C, verified under VDDIO = 4.5–5.5 V and TA = −40 to +105 °C per datasheet Section 4.3.4.

Can the 10-bit ADC operate simultaneously with CCU6 timers?

Yes - the ADC trigger source can be configured to synchronize with CCU6 timer events (e.g., PWM center-aligned period), enabling precise current sampling in motor control loops without CPU overhead or jitter.
