Product details
Overview
SAF-XE164F-48F66L AC from Infineon Technologies is a 16-bit real-time signal controller with 384 KB on-chip Flash, 16 KB PSRAM, 80 MHz CPU clock (12.5 ns instruction cycle), dual A/D converters (11+5 channels, 10-bit, <1 µs conversion), and integrated MultiCAN Rev. 2.0B interface supporting up to 4 CAN nodes. It targets motor control and industrial automation systems requiring deterministic timing, high-resolution PWM, and robust fieldbus connectivity.
For engineers reviewing the SAF-XE164F-48F66L AC datasheet, SAF-XE164F-48F66L AC pinout, SAF-XE164F-48F66L AC application, or SAF-XE164F-48F66L AC equivalent, key selection criteria include Flash/PSRAM sizing, CCU6x PWM channel count, ADC channel allocation, CAN node support, and LQFP-100 package compatibility for high-pin-count real-time control designs.
Technical Context
The XE164F derivative implements a five-stage pipeline C166-compatible CPU with single-cycle 16×16 multiply, MAC, and zero-cycle jumps, enabling deterministic execution in closed-loop motor control. Its memory subsystem includes 384 KB Flash (768 KB max across family), 16 KB PSRAM, 2 KB DPRAM, and 1 KB SBRAM - all mapped within a unified 16 MB linear address space.
Peripheral integration centers on real-time signal processing: two synchronizable 10-bit ADCs (11+5 total channels, sub-1 µs conversion), three CCU6x units for flexible PWM generation, CAPCOM2 (16-channel), GPT12E (5 timers), and a full-featured MultiCAN module with 128 message objects and gateway capability across four CAN nodes.

FAQ
What is the maximum operating temperature range for SAF-XE164F-48F66L AC?
The device is rated for operation from –40 °C to +85 °C ambient temperature, validated per Infineon's industrial qualification standards. Thermal derating is not required within this range when used with the specified 100-pin LQFP package and standard PCB copper pour guidelines.
Does SAF-XE164F-48F66L AC support JTAG-based debugging in production systems?
