A96T3F6EFN

The A96T3F6 is ABOV’s capacitive force sensor microcontroller built on an M8051 8-bit core. It is designed for force and touch scenarios—such as TWS—providing integrated sensing, signal processing and system control in a single compact device.

Key value comes from its sensor-focused peripherals, waterproof feature for wet environments, and a compact 12-DFN package that supports embedded user-interface and low-voltage designs.

Key Features

• Core & Performance  M8051 8-bit core with selectable operating speeds (16 MHz and 1 MHz) for flexible performance and power trade-offs.
• Memory  20 Kbytes of on-chip Flash program memory and 2 Kbytes of RAM for embedded firmware and runtime data.
• Power  Operates from a 1.7–2.0 V supply range suitable for low-voltage systems.
• Analog & Sensing  12-bit A/D converter (1 channel, 250 ksps) for precise analog measurement and capacitive sensing.
• Touch & Force Interfaces  Touch Key support for 7 channels and dedicated carrier generator to enable capacitive force and touch implementations; built-in false-touch prevention logic as part of the sensor-focused design.
• Timers & PWM  16-bit PWM and 16-bit/8-bit timers for timing, control and pulse generation duties.
• Connectivity  I2C interface for host communication and sensor network integration.
• System Reliability  Watchdog timer included to support reliable embedded operation.
• Oscillator & Package  Internal oscillator and surface-mount 12-DFN package (1.4 × 2.1 × 0.5 mm, 0.35 mm pitch) for space-constrained PCB layouts.
• Environmental Range  Rated for operation from −40 to 85 °C for use across a wide range of ambient conditions.

Typical Applications

• True Wireless Stereo (TWS) earphones  Capacitive force and touch control in compact earbuds, with waterproofing for sweat and moisture resistance.
• Wearable user interfaces  Touch and force sensing for compact wearables that require low-voltage operation and small package size.
• Portable consumer electronics  Buttonless user controls and gesture/force detection where integrated sensing and low-power operation are advantageous.

Unique Advantages

• Sensor-focused integration: Combines touch-key channels, carrier generator and a high-speed ADC to simplify capacitive force and touch designs and reduce BOM.
• False-touch prevention: Built-in prevention for false touches improves user experience in touch and force interfaces.
• Waterproof feature: Special waterproof capability enhances durability and reliability in wet environments such as wearables and TWS earbuds.
• Compact footprint: 12-DFN package (1.4 × 2.1 × 0.5 mm) enables integration into space-constrained products.
• Low-voltage operation: 1.7–2.0 V supply allows use in modern low-voltage battery-powered systems.
• Complete embedded control: On-chip Flash (20 KB), RAM (2 KB), timers, PWM and watchdog provide a complete single-chip control solution.
