Infineon Technologies SAF-XE164G-72F66L AC

Overview

SAF-XE164G-72F66L AC from Infineon Technologies is a 16-bit real-time signal controller with 576 KB on-chip Flash, 32 KB PSRAM, dual A/D converters (6+5 channels), CCU6x PWM units (0 and 1 enabled), and dual CAN nodes. It operates at up to 80 MHz, supports 3.0–5.5 V supply, and targets motor control and industrial automation systems requiring deterministic timing and multi-channel analog capture.

For engineers reviewing the SAF-XE164G-72F66L AC datasheet, SAF-XE164G-72F66L AC pinout, SAF-XE164G-72F66L AC application, or SAF-XE164G-72F66L AC equivalent, key selection criteria include Flash/PSRAM sizing, CCU6 module count, CAN node count (2), ADC channel allocation (6+5), and LQFP-100 package compatibility for high-pin-count embedded control designs.

Technical Context

The XE164G derivative implements a five-stage pipelined C166-compatible CPU core with single-cycle 16×16 multiply, MAC instructions, and 12.5 ns instruction cycle at 80 MHz. Its memory subsystem includes 576 KB Flash (768 KB max in family), 32 KB PSRAM, 2 KB DPRAM, and 1 KB SBRAM - all accessible within a 16 MB linear address space.

Peripheral integration centers on real-time signal processing: two synchronizable 10-bit ADCs (conversion time <1 µs), CCU6x modules for flexible PWM generation (two active), MultiCAN Rev. 2.0B interface with 2 nodes and gateway capability, and four serial channels supporting UART/LIN/SPI/I²C/IIS protocols.

Key Specifications

Pinout & Package

SAF-XE164G-72F66L AC is housed in a 100-pin Green LQFP package (0.5 mm pitch) with exposed thermal pad, rated for -40 °C to +85 °C operation. Pin definitions follow Infineon's XE164x pin configuration standard (Datasheet V2.1, Section 2.1), including dedicated XTAL1/XTAL2 inputs, JTAG debug interface (TCK/TDI/TDO/TMS/TRST), CANH/CANL differential pairs for both nodes, and grouped ADC input pins (ADCH0–ADCH10).

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The SAF-XE164G-72F66L AC operates at up to 80 MHz CPU clock frequency, delivering a 12.5 ns instruction cycle time. This is achieved using the on-chip PLL with an external crystal (1–20 MHz) or external clock source. The five-stage pipeline enables single-cycle execution of most instructions, including 16×16 multiply and 32-bit addition, ensuring deterministic real-time performance for motor control loops.

Does this device support CAN FD or only classical CAN?

The SAF-XE164G-72F66L AC implements MultiCAN Rev. 2.0B, supporting only classical CAN (ISO 11898-1) at up to 1 Mbit/s. It does not support CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. The module provides 128 message objects, dual CAN nodes, and gateway functionality - sufficient for legacy automotive and industrial networks but not for next-generation high-bandwidth CAN FD applications.

How many independent PWM channels can be generated simultaneously?

This device supports eight independent PWM output channels via two active CCU6 modules (CCU60 and CCU61), each providing four complementary PWM signals with programmable dead-time insertion. These channels are fully synchronizable and can be configured for center-aligned or edge-aligned modes - enabling precise control of two independent 3-phase inverter stages, such as dual-motor drives or interleaved power converters.

Is there on-chip debug support, and what interface is used?

Yes, the SAF-XE164G-72F66L AC includes full On-Chip Debug Support (OCDS) compliant with IEEE 1149.1 (JTAG). It uses a 5-pin JTAG interface (TCK, TMS, TDI, TDO, TRST) for non-intrusive debugging, flash programming, real-time trace, and breakpoint management. OCDS allows full visibility into CPU registers, memory, and peripheral states without halting real-time execution - essential for validating motor control timing and interrupt latency.
