Product Overview
This solution uses a single touch-enabled MCU to implement display, touch input, timer modes, and other functions for a space heater.
- Power Supply: 220V AC with adjustable hot and cool air settings.
- Control: Supports infrared (IR) remote control.
- Main Controller: HS16F3612 in a SOP20 package.
Solution Advantages
- Reduces overall cost by minimizing the Bill of Materials (BOM) and surface-mount expenses.
- Improves reliability and lowers product testing costs.
- Simplifies maintenance by integrating touch control and display driving into a single MCU.
MCU Specifications: HS16F3612
The main control unit is the HS16F3612 MCU in a SOP20 package.
Key Features
- 4K x 14-bit Flash program memory
- 336 x 8-bit EEPROM data memory
- Up to 10 touch-sensing channels
- Operating voltage: 2.2V to 5.5V
- Includes a 12-bit Analog-to-Digital Converter (ADC)
- Up to 18 general-purpose I/O (GPIO) pins
Functional Description
- A light touch on the power key turns the unit on, defaulting to cool air mode.
- The "Hot" key cycles through cool air, low heat, and high heat settings.
- The timer key allows setting a shutdown timer from one to twelve hours.
