Microchip Technology, Inc. Microcontrollers PIC18C442-I/L

The PIC18C442-I/L is a high-performance 8-bit microcontroller from Quarktwin Technology Ltd. It features a RISC CPU architecture optimized for C compiler use, with a maximum operating speed of 10 MIPS at a 40 MHz clock frequency. The device includes 16 KB of on-chip program memory and 8 KB of data memory, supporting linear addressing for both. It is equipped with a 10-bit analog-to-digital converter (ADC) and multiple timers, including Timer0, Timer1, Timer2, and Timer3, which provide various functionalities such as PWM generation and interrupt handling. The microcontroller supports a variety of communication protocols through its Master Synchronous Serial Port (MSSP) for SPI and I¬=C, as well as an addressable USART module. It also includes features for power management, such as a power-on reset, brown-out reset, and a watchdog timer. The device operates within a voltage range of 2.5V to 5.5V and is designed for low power consumption, making it suitable for battery-operated applications. The PIC18C442-I/L is pin-compatible with 40-pin PIC16C7X devices, facilitating easy integration into existing designs.
