ec78ic302a Microchip Technology announced the dsPIC33FJ12GP family of digital signal controllers (DSCs), which are suited for a new class of smart sensor applications. With 40 MIPS performance in package sizes as small as 6 mm ×6 mm, the processor can be moved closer to the sensor -- eliminating lead noise and offloading this workload from a central processor -- thereby creating a smart sensor scenario. Using libraries and filter design tools, digital filters can replace analog filters to reduce noise. The dsPIC33FJ12GP’s on-chip analog-digital-converters (ADCs), with up to 1.1 Msps, permit signal oversampling to improve signal-to-noise ratios. Spectral analysis can be conducted adjacent to the sensor, permitting robust application performance and a digital connection to upstream processors. According to the company, this DSC family has sufficient performance and resources to serve as the sole processor in some smart sensor applications. Additional features include 12 KB of Flash and 1 KB of RAM, and one UART, one SPI and one I2C port. Prices start at $1.99 each in 10,000-unit quantities.
