Microchip Technology, Inc. Microcontrollers PIC18F4439-E/ML

The PIC18F4439-E/ML is an enhanced 8-bit microcontroller from Quarktwin Technology Ltd. It features a high-performance RISC CPU capable of operating at 20 MHz, with a program memory of 12 KB and data memory of 6 KB. The device supports a variety of applications with its 100,000 erase/write cycle enhanced FLASH program memory and 1,000,000 erase/write cycle Data EEPROM memory, both of which have a retention period exceeding 100 years. This microcontroller includes a 10-bit Analog-to-Digital Converter (ADC) with fast sampling rates and the ability to convert during sleep mode. It also offers multiple peripheral features such as three external interrupt pins, various timer modules, and two PWM modules with a maximum frequency of 156 kHz at 8-bit resolution. The device is designed for single-phase induction motor control, utilizing Programmable Motor Control Technology (ProMPT,Ñ¢) for variable frequency control. The PIC18F4439-E/ML operates within a wide voltage range of 2.0V to 5.5V and is suitable for industrial and extended temperature ranges. It supports In-Circuit Serial Programming (ICSP,Ñ¢) and In-Circuit Debug (ICD) through two pins, making it versatile for development and debugging. The microcontroller's low power consumption and various built-in safety features, such as Power-on Reset and Brown-out Reset, enhance its reliability for embedded applications.
