Introduction to PIC18F452

PIC18F452 is an 8-bit with 10 MIPS, CMPS, FLASH-based microcontroller that has 34 I/O pins out of 40 Pin packages. It is a powerful microcontroller with one 8-bit and three 16-bit timers, 8-Channels 10-bit Analog-digital converter, and I2C, SPI, USART peripheral. It is a Low power microcontroller unit that consumes about less than 0.2 uA standby current and 1.6mA normal current during 5V and 4 Mhz operations.

PIC18F452 also has the feature of Programming code protection, Power-on Reset (POR), Power-up Timer (PWRT), Oscillator Start-up timer with power saving sleep mode. The watchdog timer features its own On-Chip RC Oscillator for reliable operations. 2V to 5.5V operating voltage makes the 18F452 suitable for 3.3V and 5.0V logic level operations.
