The PIC18F452-I/P with PIC microcontroller is a 40MHz, 32kB memory chip manufactured by Microchip. It has 1536B SRAM and 256B EEPROM. It is designed to be used in embedded systems, as an upgrade to the PIC16F873 or PIC16F877. It has a 32-bit processor architecture and supports up to two 8-bit or 16-bit parallel ports. It can be programmed using a C compiler and can be interfaced with hardware or software-based development tools. Its features include dedicated support for I2C, SPI, and USART serial communication protocols, extended power management features, extended sleep modes, and enhanced low-power Wake-up. Its built-in features support low power consumption, allowing it to be used in battery-powered applications. With its highly integrated peripheral support and flexibility, it is an ideal choice for embedded systems development.
