Introducing the PIC24F32KA304 Plug-In Module Overview The PIC24F32KA304 PIM is designed to demonstrate the capabilities of the PIC24F32KA304 family using the Explorer 16 Demonstration Board kit and the PICtail Plus Daughter Boards. Table 1 and Table 2 detail the pin mapping of the 44-pin device to the 100-pin PIM header. The 44-pin to 100-pin table lists the device pins and shows what functions are mapped to each. These tables are most useful for viewing multiplexing conflicts which prevent some functions from being used simultaneously. PIM Features The PIC24F32KA304 44-pin device is capable of performing all of the base functions on the Americas Europe Asia/Pacific 100-pin Explorer 16 board. In addition, the PIM is compatible with most of the PICtail Plus Atlanta - 678-957-9614 Austria - Weis - 43-7242-2244-39 Australia - Sydney - 61-2-9868-6733 Daughter Boards for the Explorer 16.

Thailand - Bangkok - 66-2-694-1351 Some Explorer 16 Boards have a 5V LCD. If you are using a function which is multi- plexed onto these pins, on one of these boards, it may be necessary to manually drive the pins initially. The pin must be driven in order to ensure the bus is driven to either VDD or VSS, instead of floating at 5V. UART1 and SPI1 are multiplexed onto the same device pins as the temperature sensor and potentiometer on the Explorer 16 Board. Jumpers are provided to remove the analog temperature sensor and potentiometer functions from the PIM. Removing the jumpers will allow the SPI1 and UART1 to function correctly.
