Infineon Technologies SAK-XC886-8FFA 5V AC

Overview

SAK-XC886-8FFA 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 24 KB Flash memory, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, operates with a 5 V I/O supply and internal 2.5 V core voltage, and supports LIN, UART, MultiCAN, and 10-bit 8-channel ADC for automotive body electronics control.

For engineers reviewing the SAK-XC886-8FFA 5V AC datasheet, SAK-XC886-8FFA 5V AC pinout, SAK-XC886-8FFA 5V AC application, or SAK-XC886-8FFA 5V AC equivalent, key selection considerations include its dual-voltage I/O architecture (5 V tolerant ports with 2.5 V core), integrated LIN transceiver support, MultiCAN 2.0B compliance, on-chip voltage regulator, and embedded debug interface via JTAG/OCDS.

Technical Context

The SAK-XC886-8FFA 5V AC implements an enhanced 8051-compatible XC800 core with two-clock-cycle execution, enabling zero-wait-state memory access. It features a dedicated on-chip voltage regulator generating 2.5 V for core logic while supporting 5 V I/O operation across Ports 0–5.

Its peripheral set includes a 10-bit 8-channel ADC with configurable conversion sequence, a MultiCAN controller compliant with CAN 2.0B, LIN 2.1-capable UART1 with automatic baud-rate detection, and a Capture/Compare Unit 6 (CCU6) optimized for motor control timing with three independent 16-bit timers and dead-time generation.

FAQ

What is the maximum operating frequency of the SAK-XC886-8FFA 5V AC?

The device supports a maximum CPU clock frequency of 26.67 MHz derived from an external crystal (1–20 MHz) multiplied by the on-chip PLL. At this speed, the two-clock-cycle architecture delivers up to 13.33 MIPS, enabling real-time response in automotive control loops without external wait states.

Does the SAK-XC886-8FFA 5V AC include a hardware LIN transceiver?

No-it integrates a LIN-compliant UART1 peripheral with automatic header detection and baud-rate synchronization, but requires an external LIN physical layer transceiver (e.g., TLE7259-3GE) for bus connection. This separation ensures flexibility in ESD robustness and electromagnetic compatibility tuning.

How is flash memory protected against unauthorized access or overwrite?

Protection is implemented via password-locked Flash sectors, read-out protection bits, and write/erase lock bits accessible only after successful password entry through the OCDS interface. These mechanisms prevent firmware extraction and accidental corruption during field updates or service programming.

Can the SAK-XC886-8FFA 5V AC operate without an external crystal?

Yes-it includes an internal RC oscillator (±10% accuracy) usable for non-timing-critical functions like wake-up or low-power mode operation. However, LIN, CAN, and precise ADC sampling require the external crystal or ceramic resonator connected to XTAL1/XTAL2 for guaranteed timing compliance.
