Infineon Technologies SAF-XC886-6FFA 5V AC

Overview

SAF-XC886-6FFA 5V 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 24 KB Flash, 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 supports CAN 2.0B, LIN, UART, SSC, 10-bit 8-channel ADC, CCU6, and on-chip debug via JTAG - deployed in automotive body control modules requiring deterministic real-time response.

For engineers reviewing the SAF-XC886-6FFA 5V AC datasheet, SAF-XC886-6FFA 5V AC pinout, SAF-XC886-6FFA 5V AC application, or SAF-XC886-6FFA 5V AC equivalent, key selection criteria include its integrated MultiCAN controller, 5 V-tolerant I/O ports, flash-based firmware update capability, and qualification for automotive ambient temperature range (–40 °C to +125 °C).

Technical Context

The XC886 implements a two-cycle-per-instruction 8051-compatible CPU with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory protection strategy includes flash sector locking and password-protected write access to critical registers.

The device features a multi-source interrupt system with configurable priority, six programmable timers (including Timer 21 for high-resolution PWM), and a dedicated Capture/Compare Unit 6 (CCU6) optimized for motor control timing with dead-time insertion and shadow register transfer.

FAQ

What is the maximum operating frequency of the SAF-XC886-6FFA 5V AC?

The SAF-XC886-6FFA 5V AC supports a maximum core clock frequency of 27 MHz, achieved via internal PLL multiplication of an external 1–20 MHz crystal or oscillator input. At this frequency, the XC800 core executes instructions in two clock cycles, delivering up to 13.5 MIPS performance. The PLL lock time is specified as ≤100 μs after power-on reset.

Does the device include an integrated CAN transceiver?

No, the SAF-XC886-6FFA 5V AC contains only the CAN protocol controller (MultiCAN module) and requires an external ISO 11898-compliant physical layer transceiver (e.g., TJA1042 or SN65HVD230) connected to CANL/CANH pins. The controller supports CAN 2.0B with bit rates up to 1 Mbps and hardware message filtering.

How is flash memory protected against unauthorized access or overwrite?

Flash protection is implemented through sector-wise lock bits (2 KB granularity), boot ROM read-protection fuse, and password-protected write access to critical registers. Once enabled, locked sectors cannot be erased or programmed without a valid 32-bit password written to the Password Register (PWRS), and the protection remains active after reset.

Can the device operate without an external crystal?

Yes - the SAF-XC886-6FFA 5V AC includes an internal RC oscillator (12 MHz nominal, ±10 % accuracy) usable for basic operation and wake-up from sleep modes. However, for CAN, LIN, or UART timing-critical applications, an external crystal (1–20 MHz) is required to meet baud rate accuracy specifications (±1.58 % for CAN at 500 kbps).
