• Interfaces  I²C ×1, SPI ×2 and USART ×2 (device-specific counts for A96T430LUN) for peripheral connectivity and host communications.
• Power & Clock  On-chip POR and Low-Voltage Reset (multiple levels), internal RC oscillators (HSIRC 16 MHz, LSIRC 32 kHz) and selectable operating frequencies (2, 4, 8, 16 MHz) to simplify clocking and reset strategy.
• Operating Range & Reliability  Wide VCC range (2.0 V to 5.5 V at 16 MHz), operating temperature −40 °C to +85 °C, and low-voltage indicator levels for robust operation in varied environments.
• Package & I/O  Available in a compact 24‑QFN (4 × 4 mm, 0.5 mm pitch) surface-mount package with device I/O pinout suitable for compact PCB designs.

Typical Applications

• Home Appliances  Capacitive user interfaces and proximity controls for ovens, dishwashers and laundry machines using the integrated touch engine and multiple timers for interface control.
• Consumer Electronics  Control panels and touch keypads in devices such as remote controls, set-top boxes and small appliances, leveraging the 19-channel touch sensing and on-chip ADC for sensor inputs.
• Smart Home Interfaces  Wall-mounted panels, smart switches and sensor hubs that require low-pin-count microcontrollers with reliable touch detection and flexible communication interfaces (I²C/SPI/USART).
• Industrial & Commercial Controls  Operator interfaces and simple control nodes that benefit from on-chip watchdog, POR/LVR and industrial temperature range for dependable field operation.

Unique Advantages

• Highly integrated functionality: On-chip Flash, SRAM, ADC and capacitive touch engines reduce BOM and board complexity for compact UI and control designs.
• Purpose-built for touch interfaces: Multi-channel self-capacitive sensing plus capacitive force sensing and touch-key interrupt wake-up provide responsive, configurable user-interface detection.
• Robust power and reset features: Built-in POR, selectable LVR levels and low-voltage indicators help ensure predictable startup and safe operation across the specified supply range.
• Flexible timing and control: Multiple 16-bit timers, an 8-bit timer, PWM channels and a watchdog timer support precise control and reliable system supervision.
• Compact industrial-ready package: 24‑QFN 4×4 mm footprint with −40 °C to +85 °C rating enables deployment in space-constrained and temperature-demanding designs.
