Product details
Overview
XE167K96F66LACFXQMA1 from Infineon Technologies is a 16-bit real-time signal controller featuring an 80 MHz CPU, 768 KB on-chip Flash, 64 KB PSRAM, dual 10-bit ADCs (16+8 channels, <1 µs conversion), and four CCU6 PWM units. It operates from 3.0–5.5 V and supports industrial motor control with integrated CAN-free serial interface set (4 UART/LIN/SPI/I²C/IIS channels).
For engineers reviewing the XE167K96F66LACFXQMA1 datasheet, XE167K96F66LACFXQMA1 pinout, XE167K96F66LACFXQMA1 application, or XE167K96F66LACFXQMA1 equivalent, key selection criteria include Flash size vs. peripheral count trade-offs, CCU6-based PWM timing precision, ADC channel mapping for multi-sensor feedback, and absence of MultiCAN in favor of enhanced serial interface flexibility.
Technical Context
The XE167K96F66LACFXQMA1 implements a five-stage pipelined C166-compatible CPU core with single-cycle 16×16 multiply, MAC, and 32-bit arithmetic. Its interrupt system supports 87 sources across 16 priority levels, with 12.5 ns sample rate and Peripheral Event Controller (PEC) for zero-overhead DMA transfers.
Peripheral integration includes two synchronizable 10-bit ADCs with hardware preprocessing (range check, data reduction), four CCU6 modules enabling independent high-resolution PWM generation per channel, and six configurable USIC channels supporting UART, LIN, SPI, I²C, and IIS protocols - all without MultiCAN functionality per derivative specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock | 80 MHz maximum; enables 12.5 ns instruction cycle for deterministic real-time loop execution in motor control. |
| Flash Memory | 768 KB on-chip; sufficient for complex field-oriented control (FOC) algorithms plus safety monitoring firmware. |
| SRAM | 64 KB PSRAM + 16 KB DSRAM + 2 KB DPRAM + 1 KB SBRAM; supports concurrent code/data execution and dual-port buffer access. |
| ADC Resolution & Speed | 10-bit, <1 µs conversion time per sample; meets fast current/voltage sampling requirements in 20 kHz PMSM drives. |
| PWM Units | Four CCU6 modules; provide independent 16-bit timers with dead-time insertion and emergency shutdown for 3-phase inverter control. |
| Serial Interfaces | Six USIC channels configurable as UART/LIN/SPI/I²C/IIS; enables sensor fusion, diagnostics, and host communication without CAN transceiver cost. |
| Supply Voltage | 3.0–5.5 V single supply; simplifies power design in industrial 5 V or automotive 3.3 V/5 V environments. |
Pinout & Package
XE167K96F66LACFXQMA1 is housed in a 144-pin Green LQFP package (19.7 mil pitch, RoHS-compliant), with thermal pad exposed on underside for enhanced heat dissipation in continuous 80 MHz operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP / VSSP | Core Power / Ground | 3.0–5.5 V digital supply pins; require local 100 nF decoupling per pair to maintain signal integrity at 80 MHz. |
| XTAL1 / XTAL2 | Crystal Oscillator Input/Output | Supports 1–20 MHz external crystal; internal PLL generates stable 80 MHz CPU clock with low jitter for timing-critical PWM. |
| ADCTRIGx | ADC Trigger Input | Hardware-synchronized sampling initiation from CCU6 timer overflow, eliminating software latency in current-loop sampling. |
| CC60SR / CC61SR | CCU6 Shadow Register Load | Double-buffered PWM compare register update on timer match, ensuring glitch-free duty cycle changes during runtime. |
| USIC0_TxD / USIC0_RxD | Universal Serial Interface Channel 0 TX/RX | Configurable for UART/LIN/SPI; supports auto-baud detection and LIN header checksum for automotive subsystem integration. |
Key Features
| Feature | Design Value |
|---|---|
| Five-stage pipelined CPU | Enables deterministic 12.5 ns instruction cycle for hard real-time control loops in servo drives. |
| Dual 10-bit ADC with preprocessing | Reduces CPU load by offloading range-check and averaging before interrupt delivery, improving loop efficiency. |
| Four CCU6 PWM units | Each provides independent 16-bit resolution, dead-time control, and emergency stop input-critical for IGBT gate driving safety. |
| Six USIC serial channels | Eliminates need for external protocol translators; one channel can run LIN while another handles SPI-connected position encoder. |
| On-chip PEC DMA controller | Performs up to eight-channel memory-to-peripheral transfers without CPU intervention, freeing cycles for algorithm execution. |
Applications

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-XE167F-96F66L | Includes 5-node MultiCAN interface; same Flash/PSRAM/ADC/CCU6 specs; adds CAN message object RAM (128 objects). | Required where CAN bus integration is mandatory (e.g., J1939 engine control); not suitable when CAN adds unnecessary BOM cost and layout complexity. | Select if CAN communication is required; otherwise XE167K avoids CAN transceiver, termination resistors, and EMC filtering overhead. |
| SAF-XE167H-96F66L | Same Flash/PSRAM/ADC/CCU6; removes MultiCAN *and* reduces USIC count from 6 to 4 channels. | Suitable for simpler serial-only designs (e.g., single UART + SPI), but insufficient for multi-protocol gateways requiring concurrent UART+LIN+SPI. | Choose only when exactly four serial interfaces suffice; XE167K's six USICs support richer peripheral connectivity without compromise. |
Compared with SAF-XE167F-96F66L, XE167K96F66LACFXQMA1 trades CAN capability for lower system cost and reduced PCB area; versus SAF-XE167H-96F66L, it retains full six-USIC flexibility critical for protocol-rich edge nodes.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time?
The XE167K96F66LACFXQMA1 achieves a maximum CPU clock of 80 MHz, delivering a 12.5 ns instruction cycle time. This timing is guaranteed under specified voltage (3.0–5.5 V) and temperature (−40 °C to +85 °C) conditions, enabling hard real-time execution of motor control algorithms with sub-microsecond jitter.
Does this device support hardware-accelerated division operations?
Yes - the CPU includes background division hardware that executes 32-bit ÷ 16-bit integer division in 21 clock cycles without blocking other instructions. This accelerates scaling calculations in PID loops and sensor linearization, avoiding costly software division routines.
How many analog input channels does the dual ADC subsystem support?
The device integrates two independent 10-bit ADC modules: ADC0 with 16 channels and ADC1 with 8 channels, totaling 24 configurable analog inputs. Each module supports hardware-triggered sampling, data preprocessing, and result buffering to DPRAM for zero-CPU-interrupt acquisition.
Is JTAG debugging supported, and what is the maximum clock speed?
Yes - on-chip debug support (OCDS) is provided via IEEE 1149.1-compliant JTAG interface. The maximum JTAG clock speed is 10 MHz, enabling high-speed programming and real-time trace debugging without compromising system stability during development.
