The PIC18F6520-I/PT is a high-performance Flash Microcontroller with 10-bit/up to 16-channel Analogue-to-digital converter (A/D). The PIC18F6520 is the natural extension of the PIC18F452 device, providing more RAM, more I/Os, a second serial communication port (as well as more timers and CCP modules) on top of the same peripheral set. It is also upward software compatible with PIC16 and PIC17 devices with a pin-out that is functionally compatible with the PIC17C75X family of OTP devices. This powerful (10 MIPS) 8-bit microcontroller with 32kB of enhanced flash program memory, 2kB of RAM, 1kB of data EEPROM, double addressable USART and the largest selection of analogue and digital peripherals. It is ideal for connectivity applications that benefit from the availability of the double asynchronous serial port, the flexible synchronous serial port (I²C™ or SPI™) as well as large amounts of RAM buffer memory and flash program memory.
