Overview

The PIC24F32KA302-I/SP is a 16-bit microcontroller featuring Microchip XLP (eXtreme Low Power) technology, designed for applications where power consumption is the primary constraint. This specific variant comes in a 28-pin SPDIP package, making it one of the few modern 16-bit MCUs suitable for through-hole assembly and breadboard prototyping. It operates between 1.8V and 3.6V and includes 512 bytes of integrated EEPROM for non-volatile data storage.

Why Choose This Part

The primary advantage is the combination of a 16-bit architecture with extreme low-power modes and a through-hole friendly 28-SPDIP package. It simplifies design by integrating 32KB of Flash and a dedicated 512-byte EEPROM, reducing external component count in simple control systems.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology for ultra-low sleep currents in devices that must operate for years on a single coin cell.
Rapid Prototyping
The 28-pin DIP package allows engineers to test 16-bit firmware on standard solderless breadboards without surface-mount adapters.
Industrial Data Logging
Employs the 512-byte internal EEPROM to store configuration constants or event logs without requiring external memory chips.
Handheld Medical Devices
Provides sufficient 16-bit processing power for signal filtering while maintaining a low power profile for portable equipment.

Getting Started

Develop using the MPLAB X IDE and the XC16 compiler provided by Microchip. Hardware debugging can be performed using the MPLAB PICkit 5 or ICD 5 in-circuit debuggers connected to the ICSP pins. For evaluation, the Explorer 16/32 Development Board can be used with a compatible Plug-In Module (PIM).
