Infineon Technologies SAK-XC888CM-8FFA AB

Overview

SAK-XC888CM-8FFA AB 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 at two clocks per machine cycle. It integrates 32 KB Flash memory, 12 KB Boot ROM, 256 B RAM, and 1.5 KB XRAM, with dual-voltage I/O (3.3 V or 5.0 V) and a 2.5 V core supplied by an embedded voltage regulator. It supports CAN 2.0B via MultiCAN, LIN, UART, SSC, ADC (10-bit, 8-channel), CCU6, and on-chip debug via JTAG.

For engineers reviewing the SAK-XC888CM-8FFA AB datasheet, SAK-XC888CM-8FFA AB pinout, SAK-XC888CM-8FFA AB application, or SAK-XC888CM-8FFA AB equivalent, key selection considerations include its integrated MultiCAN controller, dual-voltage I/O flexibility, on-chip oscillator with ±2% short-term deviation, 10-bit ADC with configurable conversion sequence, and support for LIN header transmission and boot ROM-based secure startup.

Technical Context

The XC888CM implements the XC800 architecture with two data pointers and no wait states for internal memory access. Its clock generation unit supports external crystal (1–20 MHz), RC oscillator, or external clock input, with PLL options enabling CPU frequencies up to 26.67 MHz. The embedded voltage regulator supplies stable 2.5 V to the core while allowing independent 3.3 V or 5.0 V I/O operation.

The device features a dedicated MultiCAN module supporting two full CAN nodes with message objects, time-triggered communication, and hardware acceptance filtering. Its ADC includes programmable sampling time, automatic channel sequencing, and conversion completion interrupts - all synchronized to the peripheral clock domain derived from the main system clock.

Key Specifications

Pinout & Package

SAK-XC888CM-8FFA AB 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), plus dedicated pins for CANH/CANL, LIN, XTAL1/XTAL2, RESET, VDD/VSS domains, and JTAG debug interface.

FAQ

Does SAK-XC888CM-8FFA AB support CAN FD?

No. The device integrates MultiCAN compliant with ISO 11898-1:2003 (Classical CAN 2.0B only), supporting bit rates up to 1 Mbps and 2-byte identifier filtering. CAN FD functionality requires separate 32-bit microcontrollers such as the SPC56 or Aurix families.

What is the maximum allowed ADC sampling rate?

The ADC achieves up to 100 kSPS under typical conditions: with 10-bit resolution, 1.5 µs conversion time, and minimum 1 µs acquisition time per channel. Total scan time for all 8 channels is ≤1.2 ms when using auto-sequencing and internal clock source.

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

No. The 2.5 V core regulator is internal and non-bypassable; VDDCORE is not exposed externally. The device requires only a single 3.3 V or 5.0 V supply applied to VDDIO, from which the regulator derives core voltage.

Is JTAG debugging supported in production firmware?

Yes - OCDS (On-Chip Debug Support) remains fully functional in production code. Debug access can be disabled via OCDS lock bits in the Flash protection register, but default configuration permits full JTAG read/write/trace capability without hardware modification.
