PIC18F452-I/P 8-bit microcontroller 40MHz 32KB FLASH
The PIC18F452-I/P is a high-performance 8-bit microcontroller (MCU) from Microchip Technology's PIC18F family, housed in a durable 40-pin DIP (Dual In-line Package) for easy through-hole integration. Powered by an enhanced RISC architecture, it operates at clock speeds up to 40 MHz, delivering 1 MIPS per MHz to ensure fast instruction execution for real-time control applications.
Key features include 32 KB of flash program memory (with self-programming capability for in-field updates), 1.5 KB of RAM, 256 bytes of EEPROM for non-volatile data storage, and a rich peripheral set: 8-channel 10-bit ADC (Analog-to-Digital Converter), 2 capture/compare/PWM (CCP) modules, UART/SPI/I2C communication interfaces, 33 digital I/O pins, and an on-chip watchdog timer (WDT) for system reliability. It supports a wide operating voltage range (4.0V to 5.5V), operates across -40°C to +85°C industrial temperature range, and features low-power sleep modes (10 µA typical at 3V, 1 MHz) to optimize power usage in battery-powered or energy-efficient designs.
Selection Guide & Alternative mcu Models
When selecting MCU IC, prioritize alignment with your system's voltage requirements, I/O pin count, memory needs (flash/EEPROM/RAM), and peripheral compatibility (e.g., ADC resolution, communication protocols); consider package type for PCB layout constraints and operating temperature range for environmental durability. For applications requiring alternative solutions from leading semiconductor manufacturers, the following models are recommended:
● ATmega328P (Microchip/Atmel): A popular 8-bit AVR MCU with 32 KB flash, 2 KB RAM, 8-channel 10-bit ADC, and UART/SPI/I2C interfaces, optimized for low-power embedded designs and widely used in Arduino-based projects for rapid prototyping.
● STM8S207C8T6 (STMicroelectronics): An 8-bit STM8 core MCU with 64 KB flash, 2 KB RAM, 16-bit timer modules, and CAN bus support, ideal for industrial and automotive applications requiring enhanced communication capabilities.
● MSP430F5529IPNR (Texas Instruments): A 16-bit ultra-low-power MCU with 256 KB flash, 8 KB RAM, 12-bit ADC, and USB 2.0 connectivity, suited for battery-powered applications where energy efficiency and advanced peripherals are critical.
● PIC18F4620-I/P (Microchip Technology): A pin-compatible upgrade to the PIC18F452-I/P with 64 KB flash, 3 KB RAM, and improved ADC performance, perfect for designs needing expanded memory and enhanced processing power without PCB redesign.
