32 MHz 16-bit core with integrated LCD drive
The Microchip PIC24FJ64GL302-I/ML is a 16-bit PIC microcontroller built for automotive and industrial control applications where an on-chip LCD segment driver and DMA controller reduce the CPU load during display updates. The core runs at up to 32 MHz, delivering enough throughput for real-time sensor polling, LIN/CAN communication, and a modest RTOS scheduler.
64 KB Flash, 8K x 8 RAM — firmware headroom
Program memory is 64 KB of Flash (64K x 8), which comfortably fits an automotive bootloader, a LIN protocol stack, LCD driver routines, and application code for a cluster or HVAC panel. The 8K x 8 SRAM leaves room for a modest call stack and a few hundred bytes of frame buffer for the LCD segments.
Peripheral set: DMA, LCD, PWM, WDT, and serial interfaces
On-chip peripherals include a DMA controller for memory-to-peripheral transfers without CPU intervention, a PWM module for motor or LED dimming, a watchdog timer for fail-safe reset, and an LCD segment driver for direct glass-panel drive.
28-QFN with exposed pad — thermal and layout notes
The PIC24FJ64GL302-I/ML comes in a 28-VQFN Exposed Pad package (supplier device package 28-QFN 6x6 mm). The 21 available I/O include nine multiplexed ADC inputs (10/12-bit selectable) for analog sensor readout.
Microchip lists the PIC24FJ64GL302-I/ML as Active (current production).
