Product details
Overview
SAF-XE164H-96F66L AC from Infineon Technologies is a 16-bit real-time signal controller featuring an 80 MHz CPU, 768 KB on-chip Flash, 64 KB PSRAM, three CCU6 PWM units, and dual 10-bit ADCs with 11+5 channels and sub-1 µs conversion time. It operates across –40 °C to +85 °C and supports industrial motor control, digital power conversion, and embedded automation systems requiring deterministic timing and high peripheral integration.
For engineers reviewing the SAF-XE164H-96F66L AC datasheet, SAF-XE164H-96F66L AC pinout, SAF-XE164H-96F66L AC application, or SAF-XE164H-96F66L AC equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral capabilities (including MultiCAN omission and 6 serial interfaces), and precise package-level design meaning for layout, thermal, and signal integrity planning.
Technical Context
The XE164H derivative implements a five-stage pipelined C166-compatible CPU core with single-cycle 16×16 multiply, MAC, and zero-cycle jumps-enabling deterministic real-time loop execution at 80 MHz. Its memory subsystem includes 768 KB Flash (with ECC support per datasheet Section 4.5), 64 KB PSRAM, 2 KB DPRAM, and 1 KB SBRAM, all mapped within a unified 16 MB linear address space.
Peripheral integration centers on signal conditioning and actuation: two synchronizable 10-bit ADCs (11+5 channels, <1 µs conversion), three CCU6 modules for independent 3-phase PWM generation, six USIC channels configurable as UART/LIN/SPI/I²C/IIS, and GPT12E/CCAPCOM2 timers-but omits MultiCAN entirely, distinguishing it from F/G-series variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock | 80 MHz maximum - enables 12.5 ns instruction cycle for hard real-time control loops in motor drives. |
| Flash Memory | 768 KB - sufficient for complex firmware with safety routines, calibration tables, and bootloader in one die. |
| PSRAM | 64 KB - supports large data buffers for FFT-based signal analysis or multi-axis motion profiles. |
| ADC Resolution & Speed | 10-bit, <1 µs conversion - captures fast transients in switching power supplies without aliasing. |
| PWM Units | Three CCU6 modules - independently generate synchronized 3-phase gate signals with dead-time control. |
| Serial Interfaces | Six USIC channels - configurable as UART, LIN, SPI, I²C, or IIS for sensor fusion, comms, and audio I/O. |
| Supply Voltage | 3.0 V to 5.5 V - simplifies power design in legacy 5 V industrial systems or mixed-voltage boards. |
| Operating Temperature | –40 °C to +85 °C - qualified for under-hood automotive subsystems and factory-floor PLC modules. |
Pinout & Package
SAF-XE164H-96F66L AC is housed in a 100-pin Green LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad, supporting reflow soldering and meeting RoHS/lead-free requirements per Infineon's packaging specification (Section 5.1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP / VSSP | Core Power / Ground | Dedicated 3.3 V supply pins for CPU and SRAM domains; require local 100 nF decoupling for noise immunity. |
| XTAL1 / XTAL2 | Crystal Oscillator Input/Output | Connects to external 1–20 MHz crystal; internal PLL generates 80 MHz CPU clock-no external oscillator needed. |
| ADCTRIGx | ADC Trigger Input | Hardware-synchronized sampling initiation from CCU6 or timer events-eliminates software latency jitter. |
| CC60SR / CC61SR | CCU6 Capture/Compare Output | Direct PWM output pins with programmable dead-time insertion-drives gate drivers without external logic. |
| USIC0_TxD / USIC0_RxD | Universal Serial Interface Channel 0 | Configurable UART/LIN/SPI physical layer pins-support auto-baud detection and LIN sync field generation. |
| TRST / TCK / TMS / TDO / TDI | JTAG Debug Interface | IEEE 1149.1-compliant boundary scan and on-chip debug support-enables real-time trace and flash programming. |
Key Features
| Feature | Design Value |
|---|---|
| Five-stage pipelined CPU | Enables deterministic 12.5 ns instruction cycle at 80 MHz-critical for servo loop timing budgets under 10 µs. |
| Dual synchronizable 10-bit ADCs | 11+5 channel configuration with hardware-triggered simultaneous sampling-supports current/voltage sensing in 3-phase inverters. |
| Three CCU6 PWM units | Independent 16-bit timers with dead-time control, shadow registers, and event-triggered updates-prevents shoot-through in motor drives. |
| Six USIC serial channels | Each channel supports UART, LIN, SPI, I²C, or IIS with DMA-linked FIFOs-reduces CPU load during sensor data aggregation. |
| On-chip SBRAM & DPRAM | 1 KB stand-by RAM retains critical state during sleep; 2 KB dual-port RAM enables concurrent CPU/peripheral access-ideal for real-time buffering. |
Applications
| Industrial Motor Drive | Digital Power Supply |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time signal controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XE164F-96F66L AC | Includes MultiCAN interface (4 nodes, 128 message objects); identical Flash/PSRAM/ADC/CCU6 specs. | Required for CAN-based distributed motor control networks; not suitable where CAN is unused and pin count must be minimized. | Select when CAN communication is mandatory; otherwise, XE164H reduces routing complexity and eliminates CAN termination components. |
| SAF-XE164G-96F66L AC | Removes one CCU6 unit (retains CCU60/CCU61); reduces ADC channels to 6+5; drops two USIC channels (4 total). | Targeted at cost-sensitive single-axis drives or simpler power converters where full PWM/ADC bandwidth is unnecessary. | Choose for lower-cost entry-level designs with reduced peripheral demand-saves ~$1.20/unit but sacrifices 3-phase flexibility. |
Compared with SAF-XE164F-96F66L AC, the H-variant trades CAN capability for simplified layout and lower EMI risk; versus SAF-XE164G-96F66L AC, it delivers full PWM/ADC headroom for demanding multi-axis or high-fidelity power control-making it optimal for premium industrial edge controllers.

FAQ
Does SAF-XE164H-96F66L AC support CAN communication?
No. Unlike the XE164F and XE164G derivatives, the XE164H series explicitly omits the MultiCAN module. Table 1 confirms "No CAN Node" for all H-variants. This omission reduces pin count and simplifies PCB routing for applications relying solely on UART, LIN, or SPI for host communication.
What is the maximum ADC sampling rate achievable with hardware triggering?
With synchronized dual ADCs and CCU6-triggered sampling, the device achieves up to 1 MSps aggregate throughput (500 kSPS per ADC). Each 10-bit conversion completes in under 1 µs, and hardware triggers eliminate software-induced jitter-verified in Section 3.10 and Table 4.3 of the datasheet.
Is the 768 KB Flash memory sector-erasable and support in-system programming?
Yes. The Flash supports byte/word programming and sector erasure (minimum 2 KB sectors), with dedicated command sequences accessible via the Flash API. In-system programming is enabled through the on-chip bootstrap loader and JTAG interface-detailed in Sections 4.5 and 3.5 of the datasheet.
How does the thermal pad on the LQFP package connect electrically and thermally?
The exposed thermal pad is internally connected to VSS and must be soldered to a solid copper thermal plane on the PCB. Infineon's packaging specification (Section 5.1) requires minimum 6×6 mm copper area with ≥4 thermal vias (0.3 mm diameter) to inner ground layers-ensuring junction-to-board thermal resistance ≤25 °C/W at 80 MHz operation.
