• Clock & Power — On-chip RC oscillators including HSIRC 16 MHz (±1.5% @ 0–60°C, ±2.5% @ -40–85°C) and LSIRC 32 kHz; operating voltage range 2.0–5.5 V (at 16 MHz) with on-chip POR and low-voltage reset options.
• Timers & System Reliability — Multiple timers (Basic Interval Timer, 8-bit and 16-bit timers), watchdog timer (WDT) and configurable low-voltage indicator/reset levels for reliable operation.
• Analog & Data Conversion — 12-bit A/D converter with 8 external input channels plus an internal reference channel for precision sensor measurements.
• Capacitive Touch & Force Sensing — 23-channel self-capacitive touch sensing and 4-pair capacitive force sensing for advanced touch and proximity user interfaces with enhanced noise immunity and wake‑on‑touch capability.
• Interfaces — Serial connectivity suitable for embedded systems including I2C (×1) and multiple USART/SPI channel options (device variant shows 2× SPI and 2× USART for the GRN package variant).
• GPIO & Packaging — 26 general-purpose I/O pins available on the A96T430GRN variant; supplied in a 28‑TSSOP (173 mil) surface-mount package.
• Environmental Range — Industrial temperature operation from -40°C to +85°C for broad deployment environments.

Typical Applications

• Home Appliances — Touch panel and user‑interface control for appliances using integrated multi‑channel capacitive sensing and ADC inputs for sensor feedback.
• Consumer Electronics — Touch and proximity controls in devices that require compact integration of MCU, touch sensing and ADC functionality.
• Smart Controls & HMI — Control panels and keypads using self-capacitive touch channels with interrupt wake-up and noise‑immune sensing.
• Sensor Hubs — Aggregation and ADC conversion of multiple analog sensors with serial interfaces for system communication.

Unique Advantages

• Highly integrated touch capability: 23-channel self-capacitive touch plus 4-pair capacitive force sensing reduces external components for advanced UI designs.
• On-chip mixed-signal support: 12-bit ADC with 8 inputs and internal reference channel enables multi-sensor measurement without extra converters.
• Broad voltage and temperature operation: 2.0–5.5 V supply range and -40°C to +85°C rating support a wide range of embedded deployments.
• Compact board footprint: 28‑TSSOP surface-mount package with 26 GPIOs balances I/O density and small board area for space-constrained applications.
• Reliable system features: On-chip POR, low-voltage reset options and watchdog timer help ensure predictable start-up and fault recovery.
• Flash endurance and code space: 64 Kbytes of Flash (10,000 erase/write cycles) with 4 Kbytes SRAM provides ample program and data storage for embedded firmware.
