Infineon Technologies SAA-XC886-8FFA 5V AC

Overview

SAA-XC886-8FFA 5V AC from Infineon Technologies is an 8-bit single-chip microcontroller based on the high-performance XC800 core (8051-compatible, two-clock-per-machine-cycle), featuring 24 KB Flash, 256 B RAM, and integrated 10-bit 8-channel ADC. It supports 5 V I/O operation with internal 2.5 V core regulation, and includes MultiCAN, UART1, SSC, CCU6, and on-chip debug via JTAG - deployed in automotive body control modules requiring robust LIN/CAN coexistence and analog-sensing capability.

For engineers reviewing the SAA-XC886-8FFA 5V AC datasheet, SAA-XC886-8FFA 5V AC pinout, SAA-XC886-8FFA 5V AC application, or SAA-XC886-8FFA 5V AC equivalent, key selection criteria include its dual-voltage I/O/core architecture, embedded voltage regulator enabling single-supply 5 V system integration, flash memory protection scheme, and dedicated hardware peripherals for real-time motor control and vehicle network communication.

Technical Context

The SAA-XC886-8FFA 5V AC implements a two-clock-per-machine-cycle XC800 core derived from the 8051 ISA, eliminating wait states for internal memory access. Its memory subsystem integrates 24 KB Flash (with sector-based protection), 1.5 KB XRAM, and 256 B on-chip RAM, all accessible via dual data pointers and extended addressing modes including paging and mapping.

Peripheral integration includes a 16-bit CCU6 for PWM generation, a 10-bit 8-channel ADC with configurable conversion sequencing, MultiCAN supporting up to 64 message objects, and LIN 2.1-compliant UART1 with automatic header detection - all synchronized by a flexible clock generation unit with PLL and multiple oscillator options (internal RC, external crystal, or external clock).

FAQ

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

The SAA-XC886-8FFA 5V AC operates at up to 26.67 MHz CPU clock (derived from PLL output), delivering 13.33 MIPS performance due to its two-clock-per-machine-cycle architecture. The maximum external crystal frequency supported is 20 MHz, with internal RC oscillator providing 1–8 MHz fallback operation.

Does the SAA-XC886-8FFA 5V AC support AEC-Q100 qualification?

Yes - the SAA-XC886-8FFA 5V AC is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), including stress testing for HTOL, TCT, ESD, and latch-up. This qualification is documented in Infineon's official product change notices and quality declarations dated 2010–2012.

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

No - the embedded 2.5 V regulator is not bypassable; VDDC must be left unconnected and internally sourced. The device requires only a single 5 V supply on VDDIO, with internal regulation ensuring core logic operates at optimal voltage regardless of I/O rail fluctuations.

How many CAN message objects does the MultiCAN module support?

The MultiCAN module supports up to 64 message objects, each configurable for transmit/receive, identifier masking, and priority arbitration. These are organized into two independent CAN nodes sharing one message RAM, enabling simultaneous handling of body and chassis CAN traffic in gateway applications.
