Infineon Technologies SAK-XC888-8FFA 5V AC

Overview

SAK-XC888-8FFA 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 32 KB Flash, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with dual-voltage I/O (5 V tolerant) 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 deterministic real-time response.

For engineers reviewing the SAK-XC888-8FFA 5V AC datasheet, SAK-XC888-8FFA 5V AC pinout, SAK-XC888-8FFA 5V AC application, or SAK-XC888-8FFA 5V AC equivalent, key selection criteria include its 5 V-tolerant I/O capability, integrated MultiCAN controller with message objects, on-chip voltage regulator enabling single-supply operation, and LIN header detection support for automotive network diagnostics.

Technical Context

The XC888 implements a two-cycle-per-instruction 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory architecture separates code (Flash/ROM), boot firmware (12 KB ROM), and data spaces (RAM/XRAM), with configurable protection zones for Flash and register access.

Timing is managed by a flexible clock generation unit supporting external crystals (1–20 MHz), RC oscillators, or PLL-derived clocks up to 27 MHz. Power management includes idle, power-down, and standby modes with wake-up via CAN, LIN, or external interrupt - critical for low-duty-cycle automotive sensors and actuators.

Key Specifications

Pinout & Package

SAK-XC888-8FFA 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 I/O ports (P0–P5), dedicated CAN/LIN/SSC/UART signals, reset, oscillator inputs (XTAL1/XTAL2), and power/ground terminals.

FAQ

Does SAK-XC888-8FFA 5V AC support CAN FD?

No. The device implements MultiCAN compliant with ISO 11898-1:2003 (Classical CAN 2.0B only), supporting bit rates up to 1 Mbit/s and 16 message objects. CAN FD features such as flexible data-rate and extended payload are not present in the hardware or firmware stack.

What is the maximum ADC sampling rate achievable?

The 10-bit SAR ADC achieves up to 1 MSPS conversion rate when configured for single-channel, continuous mode with minimum sampling time (1.5 µs). With 8-channel sequence scanning and auto-triggering, effective throughput drops to ~125 kSPS due to channel settling and conversion overhead.

Is external crystal required for operation?

No. The device includes an internal RC oscillator (±10% accuracy) sufficient for LIN and UART operation. An external crystal (1–20 MHz) is required only when ±1% timing accuracy is needed - e.g., for CAN bit timing or precise PWM generation.

How is flash memory protected against accidental overwrite?

Protection is enforced via Flash Lock Bits (FLB) and Sector Protection Registers (SPR). Each 2 KB Flash sector can be individually write-locked; boot ROM is permanently read-only. Unlock requires a 32-bit password written to the Password Register before erase/write commands execute.
