PIC32MX250F128D
The PIC32MX250F128D PIM is designed to
demonstrate the capabilities of the PIC32MX1XX/
2XX family of devices using development boards
such as the Explorer 16 Development Board, which
supports 100-pin PIM interfaces.
The PIC32MX1XX/2XX family of devices are high-
performance 32-bit microcontrollers in low-pin count
packages.
Table 1 shows the mapping between the
development board functions and the device pins.
