A96T430SNN

The A96T430SNN is an M8051-based 8-bit microcontroller optimized for touch and appliance applications. It integrates an 8051-compatible core with a broad set of analog and touch peripherals to simplify embedded user-interface and appliance control designs.

Targeted at touch-enabled appliances and proximity-sensing products, the device delivers integrated capacitive touch channels, a multi-channel 12-bit ADC, multiple serial interfaces, and on-chip reset/clock/watchdog functions to help reduce system BOM and improve design robustness.

Key Features

• Core — 8-bit M8051 core with 2-clock per cycle operation for predictable legacy-compatible MCU behavior.
• Memory — 64 Kbytes of on-chip FLASH (endurance: 10,000 cycles) and 4 Kbytes of SRAM for application code and data.
• Touch & Sensing — 32-channel self-capacitive touch sensing plus 4-pair capacitive force sensing; includes touch key interrupt wake-up and 10 V conducted susceptibility (CS) immunity.
• Analog — 12-bit A/D converter with 16 external input channels and one internal reference-channel for precision sensor and analog input acquisition.
• Timers & PWM — Multiple timers including Basic Interval Timer, Watchdog Timer, 8-bit T0 and several 16-bit timers for control and timing tasks; PWM channels available for drive control.
• Interfaces — Rich serial connectivity with I2C ×1, SPI ×3 and USART ×3 channels for sensor, peripheral and host communications.
• System Reliability — On-chip Power-On Reset (POR), Low-Voltage Reset (LVR) with multiple threshold levels, and Watchdog Timer for reliable start-up and fault recovery.
• Oscillators & Clock — On-chip RC oscillators including HSIRC 16 MHz and LSIRC 32 kHz; on-chip WDT oscillator and selectable operating frequencies (2, 4, 8, 16 MHz for Fsys).
• I/O and Packaging — Up to 42 usable I/O pins in a 44-LQFP package (10 × 10 mm), supporting a compact board footprint with extensive external connectivity.
• Voltage & Temperature — Wide operating voltage ranges (2.0–5.5 V @ 16 MHz; 2.7–5.5 V for 1.5% IRC and 10 V touch CS) and industrial temperature grade (−40 to +85 °C).

Typical Applications

• Home Appliances — Touch-panel control and proximity sensing for washers, dryers, ovens and other household appliances where integrated touch channels simplify UI design.
• Consumer Appliance User Interfaces — Keypad and touch-sensor controller for cooktops, microwaves and HVAC panels, taking advantage of the 32-channel capacitive sensing and interrupt wake-up.
• Smart Proximity Sensing — Embedded proximity and touch detection in smart-home devices that require reliable wake-up and noise immunity.
• Embedded Touch Interfaces for White Goods — Centralized MCU for user-interface, sensor readout and simple motor/control sequencing using on-chip ADC, timers and serial interfaces.

Unique Advantages

• Highly integrated touch and analog peripherals: 32 self-capacitance channels, 4-pair capacitive force sensing and a 12-bit, 16-channel ADC reduce the need for external controllers and ADCs.
• Robust system features: Built-in POR, multi-level LVR and a watchdog timer support reliable start-up and fault recovery in appliance environments.
• Flexible connectivity: Multiple SPI, USART and I2C ports enable straightforward connection to sensors, displays and companion MCUs.
• Compact package with extensive I/O: 42 I/O lines in a 44-LQFP (10 × 10 mm) package deliver high connectivity in a compact footprint.
• Wide operating range: Supports 2.0–5.5 V operation and −40 to +85 °C temperature range for deployment across typical appliance and consumer environments.
• On-chip oscillators with defined stability: HSIRC 16 MHz and LSIRC 32 kHz oscillators with specified tolerances simplify clocking without external crystals for many applications.
