Universal Development Board™ Reference Manual Overview The Universal Development Board (UDB) is a microcontroller development board intended to use with a wide variety of PIC microcontrollers from Microchip®. It was designed to support most 3.3V, PIC microcontrollers in 8bit, 16-bit, or 32-bit varieties. It will accommodate a wide range of Microchip PIM processor modules as well as DIP packaged parts with pin counts from 8-pin to 28-pin.

Universal Development Board™ Reference Manual 1 Power Supply The UDB can be powered in one of two ways, either by a bench supply or a wall wart type power supply attached to the power header, J20; or from the USB connector, J23, associated with the USB serial convertor. The UDB is intended to be operated from a regulated 5V power source, however with certain restrictions, a different supply voltage can be used. The absolute maximum voltage that should be applied to the power header is 6V.
Universal Development Board™ Reference Manual 2 USB to UART Serial Converter The MCP2200 is a USB-to-UART serial converter which enables USB connectivity in applications that have a UART interface. The serial signals USB-RXD, USB-TXD, USB-CTS, and USB-RTS are available at connector J22, to the right of USB connector J23. The signal names are labeled on the board.
Universal Development Board™ Reference Manual Many Microchip PIMs are not wired straight through and it is necessary to refer to the Microchip PIM information sheet to understand how they are wired. 3.1 On-Board PIC32MX360 The UDB has a PIC32MX360F512L microcontroller soldered onto the board. This microcontroller is wired to the PICtail™ Plus bus in the same manner as would be the case for a PIM plugged into the PIM Socket.
Universal Development Board™ Reference Manual The PICtail™ Plus bus is based on a 120-pin connection divided into three sections of 30pins, 30pins and 56pins. The two 30-pin connections have parallel functionality. Each 30 pin section provides connections to all of the serial communications peripherals, as well as I/O port. This functionality provides enough signals to develop many different expansion interfaces.
Universal Development Board™ Reference Manual The determination of which PIC devices are compatible with the UDB board, and which socket to use is based on the operating voltage range of the microcontroller and the layout of the power, ground and MCLR pins on the device. The UDB operates the microcontroller at 3.3V and therefore, only devices that operate at 3.3V may be used. Microchip® has several conventions for the placement of the power, ground and MCLR pins on their microcontrollers.
Universal Development Board™ Reference Manual clock source with DIP socket IC2, or in the IC3/IC4 position to use the external clock source with either of those sockets. Remove the shorting block from JP7 when using the internal oscillator option with the DIP device. 5.3 DIP Bus Header The three DIP sockets are connected in parallel and wired to the DIP bus header connector, J6. Connector J6 is used to access the I/O signals for the microcontroller being used in one of the DIP sockets.

Universal Development Board™ Reference Manual When using any of the DIP sockets, it is necessary to jumper the board to select the socket being used. Programming jumpers J15 and J16 (labeled PROG JUMPERS on the board) are used to route the programming signals PGC and PGD to the appropriate DIP socket. These jumpers are on the left side of the board near the ICSP connector. Place shorting blocks in the appropriate position of J15 and J16 for the DIP socket being used.

Universal Development Board™ Reference Manual 7.2 Low Frequency Oscillator An unloaded footprint is provided for a 32.768KHzlow frequency oscillator. If desired, an oscillator such as an Abracon ASVK-32.768ZEC can be loaded at IC1. This is a 3.3V CMOS crystal oscillator in a 7.0x5.0mm package. It will provide a low frequency time source that can be used either as a low frequency processor clock, or as a time source for a real time clock calendar (RTCC) peripheral in one of the microcontrollers.

Pmods are a line of small peripheral interface modules available from Digilent.

Universal Development Board™ Reference Manual The SPI EEPROM is wired directly to the PIM bus. To use it from a DIP device in one of the DIP sockets, it is necessary to use jumper wires from the DIP bus header to the PIM bus header to connect the appropriate DIP microcontroller pins to the above noted signals on the PIM bus. When doing this, ensure that there is no PIM installed in the PIM socket and that the on-board PIC32MX360 is disabled by removing the shorting block from the PIC32 Enable jumper.
