MICROCHIP PIC24FJ64GA004 16-Bit Microcontroller, 64KB Flash, 8KB RAM, 44-Pin TQ

The MICROCHIP PIC24FJ64GA004-I/PT is a high-performance 16-bit microcontroller designed to bridge the gap between 8-bit platforms and more complex digital signal processors. It offers enhanced computational power with up to 16 MIPS performance, making it an ideal upgrade path for applications outgrowing their 8-bit foundations without needing excessive numerical processing. Its core feature is the 64KB of internal Flash program memory, which is fully readable, writable, and erasable during operation, providing flexible in-application programming capabilities.

This microcontroller excels in power efficiency with advanced nanoWatt power-managed modes, including Run, Idle, and Sleep, allowing for significant energy savings in battery-operated or low-power designs. The integrated system features are robust, including an on-chip LDO voltage regulator, a fail-safe clock monitor (FSCM) for automatic switchover during clock failure, and comprehensive power management with power-on reset (POR) and timers.

For connectivity and control, it boasts a rich set of peripherals. These include two UART modules with support for LIN and IrDA®, I2C and SPI interfaces, a 10-bit Analogue-to-Digital Converter (ADC) with 16 channels and a 500 kSPS sampling rate, and five 16-bit timer modules. The device also includes a flexible watchdog timer (WDT) with its own low-power RC oscillator for maximum reliability.

Housed in a compact 44-pin TQFP surface-mount package, it is designed for space-constrained applications. With 35 configurable I/O pins, it offers great flexibility for interfacing with sensors, actuators, and communication buses. Its wide operating voltage range of 2V to 3.6V and an extended temperature range from -40°C to 85°C make it suitable for demanding industrial environments, computer peripherals, and embedded systems where reliability is critical.
