Flash memory added to smallest digital signal controllers

Expanded low pin count 16-bit Digital Signal Controller (DSC) portfolio

01/17/2008


Microchip Technology Inc. has expanded its low pin count 16-bit Digital Signal Controller (DSC) portfolio with three dsPIC33F General Purpose Family members and three dsPIC33F Motor Control/Power Conversion Family DSCs. The General Purpose DSCs feature 16 or 32K of Flash memory with 28- or 44-pin packages and provide a pin- and code-compatible migration path for PIC24 microcontrollers. The devices feature an on-chip Analog-to-Digital-Converter (ADC), with up to 1.1 Msps, and serial interfaces such as I2C, SPI, and UART. The three dsPIC33F Motor Control Family DSCs add a motor-control PWM with two independent clock sources for advanced motor control or inverter algorithms using a single DSC. The on-chip PWM peripheral is designed for power-conversion and lighting applications. They include a quadrature encoder interface for sensor-based motor applications. Both feature Peripheral Pin Select, which allows designers to remap digital I/O to optimize board layout, permitting smaller boards, less noise, and the use of a lower pin count DSC.
