A31T214RLN

The A31T214RLN is a 32-bit touch sensing microcontroller from Abov, built around an ARM Cortex-M0+ core. It combines touch and display-oriented peripherals with general-purpose MCU resources to address user-interface and embedded control applications.

With integrated flash and SRAM, extensive I/O, multi-channel analog and timer peripherals, and support for internal and external clocking and low-power modes, the A31T214RLN targets consumer and home-electronics designs that require touch-key control and display handling in a compact 64-LQFP package.

Key Features

• Core and Clock  ARM Cortex-M0+ 32-bit core with CPU clock options at 48 MHz and 32 MHz; supports internal and external oscillators and PLL for flexible clocking.
• Memory  128 Kbytes of on-chip FLASH program memory and 16 Kbytes of SRAM for application code and runtime data.
• Touch and Display  Built-in touch key engine supporting 24 touch channels and on-chip LCD and LED driver functionality (series feature set) for integrated user-interface implementations.
• Analog  12-bit ADC with 15 channels and up to 150 ksps for sensor and analog input acquisition.
• Timers and PWM  Multiple 16-bit timers (×4), 16-bit PWM channels (×6) and additional timer resources for motor control, dimming and timing tasks.
• Connectivity  I2C (2 channels) and USART (2 channels) for serial communications and peripheral interfacing.
• System and Performance  High-speed internal oscillator (HSI), PLL, CRC generator and DMA support for efficient data movement and integrity checks.
• Reliability and Power  Watchdog timer, POR/LVR/LVI reset features and support for SLEEP and POWER DOWN modes to manage power consumption and system reliability.
• I/O and Packaging  Up to 60 programmable I/O pins in a 64-LQFP (10 × 10 × 0.5 mm) surface-mount package suitable for compact PCB layouts.
• Supply and Temperature  Wide operating voltage range of 1.8 V to 5.5 V and operating temperature from -40 °C to 85 °C for broad environmental compatibility.

Typical Applications

• Home Appliances  Touch-based user interfaces and display control for appliances where integrated touch sensing and peripheral control simplify the design.
• Consumer Electronics  Panel and control modules combining multiple touch keys, ADC sensor inputs and display/LED drivers in a single MCU.
• Embedded Control Units  General embedded control tasks requiring multiple timers, PWM channels and analog inputs alongside robust I/O availability.

Unique Advantages

• Highly integrated touch and display subsystem: 24-channel touch key support plus LCD/LED driver capability reduces external components for UI-focused designs.
• Balanced memory and performance: 128 KB flash and 16 KB SRAM coupled with a Cortex-M0+ core at up to 48 MHz provide a practical mix of code space and runtime performance.
• Flexible power and clock management: Internal/external oscillators, PLL and low-power modes enable designers to optimize power consumption across a wide supply range (1.8–5.5 V).
• Comprehensive peripheral set: Multi-channel ADC, multiple timers, PWMs, serial interfaces and DMA support enable consolidated control of sensors, actuators and communications.
• Wide operating range and robust resets: -40 °C to 85 °C operation and integrated POR/LVR/LVI and watchdog features support reliable operation in diverse environments.
• Compact, industry-standard package: 64-LQFP surface-mount package with up to 60 I/O pins simplifies integration into space-constrained consumer and appliance PCBs.
