A96T448FRN

The A96T448FRN is an 8-bit touch microcontroller optimized for touch and proximity sensing with integrated water-shield support. It is built around an M8051-compatible CoreM8051 running up to 16 MHz and combines touch key handling, analog conversion, timers and high-current I/O in a single 20-pin TSSOP package.

Designed for embedded user interfaces and appliance control, the device targets applications that require robust touch sensing (including water-shield protection), low-voltage operation and compact BOM integration while providing on-chip peripherals for sensor, LED and communications tasks.

Key Features

• Core – 8-bit M8051 (CoreM8051) CPU with an internal 16 MHz RC oscillator (HSIRC), providing a compact, familiar MCU architecture for embedded control.
• Memory – 32 Kbytes of on-chip Flash program memory (10,000 cycle endurance) and 2.5 Kbytes of SRAM for application code and runtime data.
• Touch and Water Shield – 15 touch key channels for self-capacitive sensing plus an integrated 4-channel water shield mesh to maintain reliable touch operation in wet or high-humidity environments.
• Analog – 12-bit A/D converter with 5 external channels and 150 ksps sampling capability for sensor interfacing and analog measurements.
• Timers & Safety – Basic Interval Timer (BIT), Watchdog Timer (WDT) and a set of timers including one 8-bit timer and multiple 16-bit timers for precise timing, PWM generation and control tasks.
• PWM & LED Drive – Multiple 8-bit PWM channels and high-sink current ports (8 high-sink ports) for direct LED driving and lighting control.
• Interfaces – On-chip serial interfaces including I²C, USART and SPI channels for external device communication and system integration.
• Power & Voltage – Wide operating voltage range from 2.0 V to 5.5 V (supports 16 MHz operation) with multiple reset and low-voltage indicator levels for reliable power management.
• Package & Temperature – Space-efficient 20-pin TSSOP package rated for industrial temperature range (‑40 °C to +85 °C).

Typical Applications

• Home Appliances – Capacitive touch control panels and user interfaces where water or moisture resistance is required for reliable operation.
• Consumer Electronics – Compact touch key control and LED indication for devices that need integrated ADC, timers and serial interfaces.
• Smart Home Control – Touch-enabled switches and control nodes that benefit from on-chip communications (I²C, USART, SPI) and low-voltage operation.

Unique Advantages

• Integrated touch with water-shield: Built-in 15-channel touch sensing plus a 4-channel water shield mesh reduces external components and improves reliability in wet environments.
• Compact system integration: On-chip Flash, SRAM, ADC, PWMs, LED high-sink ports and multiple timers consolidate functionality and lower BOM count.
• Flexible power range: 2.0 V to 5.5 V operation at 16 MHz supports a wide variety of power architectures and battery-powered designs.
• Familiar 8051 architecture: M8051 core offers a well-known development model and straightforward migration for established embedded toolchains and firmware libraries.
• Industrial temperature rating: Specified for −40 °C to +85 °C, enabling deployment in a wide range of environmental conditions.
