Infineon Technologies SAF-XC888C-8FFI 3V3 AC

Overview

SAF-XC888C-8FFI 3V3 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, 1.5 KB XRAM, and 256 B RAM, with dual-voltage I/O (3.3 V) and internally regulated 2.5 V core supply. It supports CAN 2.0B via MultiCAN, 10-bit 8-channel ADC, and CCU6 for motor control - deployed in automotive body electronics and industrial motor drives.

For engineers reviewing the SAF-XC888C-8FFI 3V3 AC datasheet, SAF-XC888C-8FFI 3V3 AC pinout, SAF-XC888C-8FFI 3V3 AC application, or SAF-XC888C-8FFI 3V3 AC equivalent, key selection criteria include its embedded voltage regulator enabling mixed-voltage operation, MultiCAN interface with message object handling, CCU6 timer for 6-channel PWM generation, and LIN-compliant UART1 for automotive sub-networks.

Technical Context

The XC888C implements a two-cycle-per-instruction XC800 core derived from the 8051 architecture, supporting dual data pointers and register banking. Its memory subsystem includes 32 KB Flash with sector protection, 12 KB ROM for boot code, and 1.5 KB XRAM accessible via MOVX, all mapped into a unified 64 KB address space using paging and mapping extensions.

Peripheral integration centers on real-time control: MultiCAN provides 16 message objects with hardware acceptance filtering; CCU6 delivers six complementary PWM outputs with dead-time insertion and emergency shutdown; and the 10-bit ADC supports scan mode with up to 8 channels and configurable conversion timing synchronized to CCU6 events.

FAQ

Does SAF-XC888C-8FFI 3V3 AC support CAN FD?

No. This device implements MultiCAN compliant with ISO 11898-1:2003 (Classical CAN), supporting up to 1 Mbit/s with 16 message objects and hardware ID filtering. CAN FD features such as flexible data rate and extended payload are not present in the XC888C peripheral set.

What is the maximum operating frequency of the CPU core?

The XC800 core runs at up to 26.7 MHz when driven by a 53.4 MHz external oscillator, due to its two-clock-cycle-per-instruction architecture. The on-chip PLL can multiply the crystal input (1–20 MHz) to generate the required system clock.

Is the 12 KB Boot ROM field-programmable or read-only?

The 12 KB Boot ROM is factory-programmed and read-only. It contains bootloader code supporting UART-based firmware updates and cannot be modified in the field. Application code resides in the 32 KB Flash memory, which is fully erasable and reprogrammable.

Can the ADC operate synchronously with CCU6 PWM events?

Yes. The ADC supports hardware trigger modes where conversions start automatically on CCU6 period match, compare match, or shadow transfer events - enabling precise current sampling aligned to inverter switching edges for motor control.
