Infineon Technologies SAK-XC888-8FFI 5V AC

Overview

SAK-XC888-8FFI 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; features a 10-bit 8-channel ADC, MultiCAN interface, LIN support, and embedded voltage regulator supplying 2.5 V core logic from 5 V I/O supply. Used in automotive body control modules requiring integrated CAN/LIN communication and analog sensing.

For engineers reviewing the SAK-XC888-8FFI 5V AC datasheet, SAK-XC888-8FFI 5V AC pinout, SAK-XC888-8FFI 5V AC application, or SAK-XC888-8FFI 5V AC equivalent, key selection criteria include Flash size (32 KB), dual-voltage operation (5 V I/O / 2.5 V core), MultiCAN v2.0B compliance, LIN 2.1 header detection capability, and 10-bit ADC with 8 input channels and configurable conversion sequence.

Technical Context

The XC888 implements a two-clock-cycle-per-machine-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory protection strategy includes flash lock bits, password-protected register access, and bit-level protection for critical SFRs.

The device integrates a fully compliant Controller Area Network (MultiCAN) module supporting CAN 2.0B protocol with 64 message objects, plus a dedicated LIN master/slave controller with automatic baud rate detection and header synchronization-both operating independently of CPU load via dedicated DMA-like message handling.

FAQ

Does SAK-XC888-8FFI 5V AC support JTAG debugging?

Yes, it includes full on-chip debug support via IEEE 1149.1-compliant JTAG interface with OCDS (On-Chip Debug Support) module. The JTAG ID register is accessible at address 0xF000, enabling boundary scan, flash programming, and real-time variable inspection using Infineon's DAS and iLLD tools.

What is the maximum ADC sampling rate achievable?

The 10-bit ADC achieves up to 100 kSPS maximum conversion rate when configured for single-channel continuous mode with minimum acquisition time (1.5 µs). With 8-channel auto-scanning and 12-clock conversion time, effective throughput drops to ~12.5 kSPS per channel.

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

No-the internal 2.5 V regulator is not bypassable; VDDCORE is internally generated and not accessible externally. The device requires only a single 5 V supply applied to VDDIO, with mandatory 100 nF ceramic decoupling between VDDCORE and VSS near the thermal pad.

Is the MultiCAN module compatible with CAN FD?

No-it implements CAN 2.0B protocol only (ISO 11898-1:2003), supporting up to 1 Mbps classical CAN frames with 11-bit identifiers. CAN FD functionality is not present; this device predates CAN FD standardization and lacks required arbitration bit timing and payload extension logic.
