Infineon Technologies SAK-XC886CM-6FFA 5V AC

Overview

SAK-XC886CM-6FFA 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 dual-voltage I/O (5 V) and core logic (2.5 V via embedded regulator). It features a 10-bit 8-channel ADC, MultiCAN interface, CCU6 capture/compare unit, and LIN protocol support - deployed in automotive body control modules requiring deterministic real-time response.

For engineers reviewing the SAK-XC886CM-6FFA 5V AC datasheet, SAK-XC886CM-6FFA 5V AC pinout, SAK-XC886CM-6FFA 5V AC application, or SAK-XC886CM-6FFA 5V AC equivalent, key selection criteria include its 5 V-tolerant I/O capability, integrated CAN/LIN transceivers, flash memory protection scheme, and on-chip debug support via JTAG for automotive ECU firmware development and validation.

Technical Context

The SAK-XC886CM-6FFA 5V AC implements a two-clock-per-machine-cycle XC800 core derived from the 8051 architecture, enabling zero-wait-state memory access. It includes dedicated hardware accelerators: a 16-bit multiplication/division unit (MDU) and a CORDIC coprocessor for trigonometric and vector math - critical for motor control loop computation.

Its peripheral set is optimized for automotive subsystems: MultiCAN controller with message objects and FIFO handling, SSC synchronous serial interface supporting SPI/I²S modes, and CCU6 with three independent 16-bit timers and PWM outputs for three-phase inverter gate driving. The on-chip voltage regulator supplies stable 2.5 V to the core while allowing 5 V I/O operation.

FAQ

Does SAK-XC886CM-6FFA 5V AC support CAN FD?

No. The device integrates a classical MultiCAN controller compliant with ISO 11898-1 (CAN 2.0B), supporting up to 1 Mbps data rate and 16 message objects. It does not implement CAN FD framing, arbitration bit rate switching, or extended data length features - those require later-generation Infineon AURIX or XC2000 derivatives.

What is the maximum ADC sampling rate achievable?

The 10-bit ADC achieves a maximum conversion rate of 100 kSPS under optimal conditions: 10 µs conversion time per sample, with sequential channel scanning enabled and no interrupt latency penalties. Actual throughput depends on channel count, trigger source (timer vs. software), and result readout method (polling vs. DMA-like register transfer).

Is external crystal required for CAN operation?

No. The on-chip oscillator supports CAN timing stability requirements when used with a 1–20 MHz external crystal or ceramic resonator connected to XTAL1/XTAL2. Internal RC oscillator is not recommended for CAN due to insufficient frequency accuracy (<1 % drift); crystal-based clocking ensures proper bit timing compliance per ISO 11898-1.

How is flash memory protected against accidental overwrite?

Protection is enforced via a multi-layer scheme: sector-level write/read lock bits controlled by the Password Register (PWR), combined with a bit-protection mechanism that disables erase/write access unless a valid 32-bit password is written first. This prevents unintended firmware corruption during field updates or debugging sessions.
