Microchip PIC18F252-I/SP 8-Bit Microcontroller Data Sheet and Technical Specifications

The Microchip PIC18F252-I/SP is a high-performance member of Microchip's renowned PIC18 family of 8-bit microcontrollers. Housed in a 28-pin SPDIP package, this device is engineered for applications requiring a robust set of peripherals, enhanced core performance, and a significant amount of memory, all within a cost-effective solution.

At its core, the microcontroller features an enhanced PIC18 architecture with a 16-bit wide instruction set and an 8-bit wide data path. Operating at a maximum frequency of 40 MHz, it achieves a performance level of 10 MIPS, providing the necessary computational power for complex control tasks. A key feature is its large memory configuration, including 32 KB of flash program memory, 1536 bytes of RAM, and 256 bytes of EEPROM data memory, offering ample space for both code and data storage in demanding applications.

The integrated peripheral set is comprehensive and designed for embedded connectivity. It includes multiple communication interfaces: a Master Synchronous Serial Port (MSSP) module that can be configured for either SPI or I²C mode, and an Enhanced Addressable USART for advanced serial communications. For analog signal acquisition, it is equipped with a 10-bit Analog-to-Digital Converter (ADC) with up to 11 input channels. Timing and control functions are handled by multiple timers, including 8-bit and 16-bit timers and Capture/Compare/PWM (CCP) modules, which are essential for generating precise waveforms for motor control or power conversion.

The device operates over a wide voltage range (2.0V to 5.5V) and is specified for the industrial temperature range (-40°C to +85°C), making it suitable for harsh environments. Its nanowatt-technology power management modes, including idle, sleep, and peripheral module disable features, are critical for designing power-sensitive, battery-operated products.
