1 Functional Description

The PIC32MX250F12B microcontroller features a 32-bit MIPS processor core capable of running at up to 50 MHz (). The DP32
operates the microcontroller at 40Mhz by default.The microcontroller features 128 KB of flash program memory and 32 KB of SRAM
data memory. Programming the DP32 can be done using the Multi-Platform Integrated Development Environment (MPIDE) or with
the advanced Microchip MPLAB® IDE with the addition of a PICKit3 or chipKIT PGM in-system programmer/debugger.
The DP32 provides 19 I/O pins as located on two through-hole header footprints. Some pins share functions with the onboard circuits
such as the on-board 8 MHz () oscillator or USB data lines (see the schematic for details). If these peripherals are needed in the design
then the microcontroller can be reconfigured to allow these pins to be used for other purposes. Nine of the digital I/O pins are shared
with the analog inputs and can be used as analog input pins.
The PIC32MX250F128B microcontroller supports peripheral functions such as UART, SPI, and I C, as well as pulse-modulated outputs.
To use the peripheral functions the PIC32MX2xx family of microcontrollers features a mappable I/O system called peripheral pin select
(PPS), which allows select peripheral functionality to be mapped to a multiple pins on the device. The default DP32 board support files
provide a specific mapping of peripheral functions to microcontroller pins. This default pinout can be over-ridden by the user's sketch if
a different mapping is desired.
Additional features of the board include an 8-pin DIP header labeled IC4 that is mapped for use with a customer supplied Microchip
25LC256 EEPROM (). The SPI bus and power signals are mapped to the correct pins so that the user can solder in an 8-pin dip socket
or directly solder the IC into the holes. Similarly the IC3 header on the board is mapped for a customer supplied Microchip MCP9701A
analog temperature sensor.
