A96T346DF

The A96T346DF is an 8-bit CMOS microcontroller based on an 8051 core running up to 16 MHz, integrating 16 KB of on-chip FLASH and a range of analog and digital peripherals. It is designed for embedded control applications that require compact hardware, touch input, sensor interfacing and low-power operation.

With built-in self-capacitive touch support, multi-channel ADC, PWM and communication peripherals, the device reduces external component count while providing the key building blocks for touch-enabled user interfaces and sensor-driven controls.

Key Features

• Core & Performance 8051-compatible 8-bit core with a maximum clock of 16 MHz for deterministic embedded control tasks.
• Memory 16 KB FLASH program memory and 2 KB RAM total (256 bytes SRAM + 1,792 bytes XRAM) for application code and runtime data.
• Analog & Data Conversion 12-bit ADC with 5 channels and up to 250 ksps for accurate sensor measurements and analog signal sampling.
• Touch Sensing 8-channel self-capacitive touch switches integrated on-chip to implement touch user interfaces without external touch controllers.
• Timers & PWM 16-bit timer/counter and 16-bit PWM output for timing, control and pulse-width modulation functions.
• Communications I2C interface for peripheral and sensor connectivity.
• System Reliability On-chip Power-on Reset (POR), Brown-Out Detection (BOD) and Watch Dog Timer for robust system behavior.
• Clock & Power Internal oscillator/clock circuitry plus power saving modes to reduce power consumption in battery- or energy-conscious designs.
• Supply & Environmental Operates from 2.7 to 3.6 V and specified for an operating temperature range of -40 to 85 °C.
• Package & Mounting Compact 10-pin DFN surface-mount package (10-DFN, 1.8 × 2.1 × 0.4 mm) suitable for space-constrained designs.
• GPIO 8 general-purpose I/O lines for direct control and interfacing to external devices.

Typical Applications

• Touch user interfaces — Implement multi-button touch panels, keypad replacements or simple gesture inputs using the integrated 8-channel self-capacitive touch engine.
• Sensor readout and control — Use the 12-bit ADC (5 ch) alongside timers and PWM for sensor measurement, control loops and actuator drive.
• Battery-powered embedded devices — Low-voltage operation (2.7–3.6 V) and power saving modes help extend battery life in portable products.
• Compact control modules — The 10-DFN package and integrated peripherals reduce PCB area and BOM for compact, space-constrained applications.

Unique Advantages

• Integrated touch and control peripherals — On-chip 8-channel touch, ADC, PWM and timers minimize external components and simplify system design.
• Balanced memory footprint — 16 KB FLASH with 2 KB RAM (including XRAM) provides on-chip program storage and runtime memory for embedded control firmware.
• Robust system supervision — POR, BOD and Watch Dog Timer support reliable startup and fault recovery.
• Compact, manufacturable package — 10-DFN surface-mount package enables small form-factor PCBs and automated assembly.
• Sensor-grade ADC performance — 12-bit resolution and up to 250 ksps sampling rate for precise analog measurement in control and monitoring applications.
• Low-voltage, low-power operation — 2.7–3.6 V supply range combined with power saving modes for energy-conscious designs.
