Infineon Technologies SAK-XC886C-8FFI 5V AC

Overview

SAK-XC886C-8FFI 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 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 LIN communication, MultiCAN, 10-bit 8-channel ADC, and CCU6 for motor control - deployed in automotive body electronics and industrial motor drives.

For engineers reviewing the SAK-XC886C-8FFI 5V AC datasheet, SAK-XC886C-8FFI 5V AC pinout, SAK-XC886C-8FFI 5V AC application, or SAK-XC886C-8FFI 5V AC equivalent, key selection considerations include its 5 V-tolerant I/O capability, integrated LIN transceiver support (no external level shifter), 16-bit CCU6 timer for PWM generation, and dual UART interfaces for diagnostics and host communication.

Technical Context

The XC886C 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 24 KB Flash (program storage) from 12 KB Boot ROM (pre-programmed startup routines) and includes memory protection via password-protected flash sectors and bit-level write protection.

Peripherals include a 10-bit SAR ADC with 8 input channels and configurable sampling timing, a 16-bit Capture/Compare Unit 6 (CCU6) supporting center-aligned PWM for three-phase motor control, and MultiCAN v2.0B with two independent CAN nodes - all operating under a flexible clock system with PLL, internal RC oscillator, and external crystal support up to 20 MHz.

Key Specifications

Pinout & Package

SAK-XC886C-8FFI 5V AC is housed in a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across six bidirectional I/O ports (P0–P5), power supply pins (VDD, VSS, VDDA, VSSA), reset (RST), oscillator (XTAL1/XTAL2), debug (TCK/TMS/TDI/TDO), and peripheral-specific signals including CANL/CANH, LIN, and ADC inputs.

FAQ

Does SAK-XC886C-8FFI 5V AC support in-system programming via its on-chip bootloader?

Yes. The device includes a 12 KB Boot ROM containing a factory-programmed serial bootloader accessible via UART0 or UART1. It supports Flash programming using Infineon's DAS (Device Access Service) protocol over standard RS-232 or LIN physical layer, enabling field firmware updates without JTAG hardware.

What is the maximum operating frequency of the internal oscillator and can it be used for real-time clock generation?

The internal RC oscillator operates at 1.5 MHz ±10% over temperature and voltage, and is not specified for RTC use. For accurate timing, the device supports external crystals up to 20 MHz or ceramic resonators; the PLL can multiply this to 26.67 MHz system clock, with dedicated prescalers enabling precise 1 Hz RTC derivation from XTAL1.

How does the CCU6 unit handle dead-time insertion for three-phase inverter gate drivers?

The CCU6 includes dedicated dead-time generators per PWM channel with programmable delay (1–128 clock cycles) and automatic polarity inversion. It synchronizes edge transitions across all six outputs (UH/UL, VH/VL, WH/WL) to prevent shoot-through, and supports both center-aligned and edge-aligned PWM modes with hardware-triggered emergency stop.

Is the 10-bit ADC calibrated at factory, and what is its effective number of bits (ENOB) under typical operating conditions?

The ADC undergoes one-time factory calibration for offset and gain error, stored in dedicated Flash locations. At 5 V supply and 25 °C, typical ENOB is 9.2 bits (based on measured SNR of 57.5 dB), degrading to 8.7 bits at 125 °C due to increased thermal noise - sufficient for motor phase current sensing and battery voltage monitoring.
