DSPIC33FJ16GS504-E/PT Product Overview

The DSPIC33FJ16GS504-E/PT is a Microchip 16-bit Digital Signal Controller (DSC) in a 44-lead TQFP package, designed for low-voltage (3.3V) digital power, precision motor control, and embedded applications requiring a large number of analog channels and high-speed sampling. Based on the dsPIC33F core running at 40 MIPS, the DSPIC33FJ16GS504-E/PT integrates 16KB Flash and 2KB SRAM. On-chip peripherals include four independent PWM generators that can produce four complementary PWM pairs with high-resolution duty cycle and real-time updates. The analog front-end features a 10-bit high-speed ADC (up to 4 Msps, up to 24 analog input channels) and four high-speed analog comparators for fast cycle-by-cycle current limiting and protection. Communication interfaces are abundant, providing 2× UART, 2× SPI, and 2× I2C, with Peripheral Pin Select (PPS) for flexible pin mapping. Operating from 3.0V to 3.6V with an extended temperature range of -40°C to +125°C, the DSPIC33FJ16GS504-E/PT is ideal for high-temperature digital power converters, multi-channel sensor acquisition, industrial motor drives, and real-time control systems needing multiple communication ports in a compact footprint.
