The A96T218KLN is an advanced CMOS 8-bit microcontroller based on an 8051 core with 32 Kbytes of on-chip Flash. It is designed for flexible, cost-effective embedded control applications requiring integrated user interfaces, analog acquisition and display driving.

With an internal 16 MHz oscillator, up to 30 I/O pins and a suite of on-chip peripherals including touch sensing, ADC, timers, PWM and serial interfaces, the A96T218KLN reduces external component count and simplifies system design.

Key Features

• Core and Performance 8051-based 8-bit microcontroller with an internal high-speed oscillator (HSI) running at 16 MHz for predictable system timing.
• Memory 32 Kbytes of Flash program memory with 256 bytes SRAM and 1.75 Kbytes xRAM for code and data storage.
• Power and Voltage Operates from 2.0 to 5.5 V and includes on-chip power management features such as power saving modes for reduced active and idle power use.
• Timers and PWM Integrated 16-bit Timer/Counter and 16-bit PWM peripheral for precise timing and control tasks.
• Analog 12-bit A/D converter with 8 channels and up to 125 ksps sampling rate for accurate sensor interfacing and analog monitoring.
• Touch and Haptic 24-channel self-capacitive touch key support for capacitive user interfaces and direct buzzer control for audible feedback.
• Display Drive On-chip 8-common × 20-segment LED driver to directly drive multi-segment indicators and reduce external driver components.
• Communications Standard serial interfaces including I2C, SPI and USART for flexible peripheral and host connectivity.
• System Reliability Built-in POR, BOD, LVI and a watchdog (WDT) support robust system start-up, brown-out protection and fault recovery.
• Package and Temperature Available in a 32-LQFP package (7 × 7 mm, 0.8 mm pitch) and specified for an operating temperature range of −40 to 85 °C.

Typical Applications

• Embedded control systems — Core MCU functions, timers, PWM and watchdog make it suitable for compact embedded controllers.
• User interface and touch control — 24-channel self-capacitive touch keys enable capacitive button panels and touch-based inputs.
• Sensor acquisition and processing — 12-bit ADC (8 channels, 125 ksps) supports multi-sensor analog measurements and conditioning.
• Indicator and display control — The 8-common × 20-segment LED driver simplifies driving multi-segment LED indicators directly from the MCU.

Unique Advantages

• Highly integrated peripherals: Touch sensing, ADC, LED driver, timers and serial interfaces on-chip reduce external BOM and board complexity.
• Flexible power operation: 2.0–5.5 V supply range and power saving modes support a wide range of supply scenarios and energy-conscious designs.
• Compact implementation: 32-LQFP package and up to 30 I/O pins provide a balance of I/O density and small PCB footprint.
• Robust system protection: POR, BOD, LVI and WDT provide layered protections for reliable start-up and operation across conditions.
• Integrated display and UI support: Dedicated touch key channels and an LED driver allow designers to implement rich user interfaces with fewer external components.
