16位开发套件

Microchip Technology’s 16-Bit Development Board Kit provides a low-cost, highly configurable development system for Microchip’s new line of PIC24F 20 and 28-pin Extreme Low-Power () microcontrollers, including the PIC24F16KA102 and PIC24FJ64GA102 families.

The XLP 16-bit board permits users to explore and evaluate extreme low-power features, and learn low-power software and hardware techniques. Various headers are available to measure both microcontroller and component power consumption. It is flexible, supporting six different power sources over a wide voltage range. It is highly configurable, equipped with a variety of common peripheral components that can be selectively enabled. Finally, it is expandable through its modular interface, providing for the addition of advanced interfaces and connectivity methods.

As provided, the XLP 16-Bit Development Board functions as a demonstration platform on initial power-up. The included demonstration software takes a temperature measurement, datalogs information to the serial data EEPROM and displays information to a host PC via a USB connection. Additional software is provided to demonstrate low-power techniques and IC interface routines.
