Product details
Overview
SAF-XE164FM-48F80L AA from Infineon Technologies is a 16-bit real-time signal controller in the XE166 family, designed for deterministic motor control and industrial automation. It features an 80 MHz C166-compatible CPU with five-stage pipeline, 576 KB on-chip Flash, 16 KB DSRAM, dual 10-bit ADCs (≤1 μs conversion), and integrated MultiCAN Rev. 2.0B supporting up to 4 nodes - deployed in servo drives and PLC I/O modules.
For engineers reviewing the SAF-XE164FM-48F80L AA datasheet, SAF-XE164FM-48F80L AA pinout, SAF-XE164FM-48F80L AA application, or SAF-XE164FM-48F80L AA equivalent, key selection criteria include CAN node count, ADC channel concurrency, CCU6x PWM resolution, SBRAM retention behavior, and external bus timing compliance for legacy peripheral interfacing.
Technical Context
The SAF-XE164FM-48F80L AA implements a C166v2 CPU core with MPU, zero-cycle jumps, and MAC instructions optimized for real-time loop execution. Its memory subsystem includes ECC-protected Flash, 8 KB stand-by RAM with battery backup support, and dual-port RAM for concurrent CPU/PEC access.
Peripheral integration centers on deterministic timing: CCU6x units deliver 16-bit PWM with dead-time control and emergency shutdown; two synchronized ADCs provide simultaneous sampling across 16 channels with hardware range checking and broken-wire detection; MultiCAN enables gateway routing between four independent CAN buses.
