Microchip Technology Inc. announced that it has begun volume production of two 16-bit dsPIC Digital Signal Controllers (DSCs) that offer designers performance speeds of 20MIPS and 30MIPS, self-programming capabilities via Flash memory, and industrial and extended temperature ranges.

The dsPIC30F3012 and dsPIC30F3013 sensor family devices feature 24KB of Flash program memory and can operate at full speed using an internal oscillator. he devices are offered in 18-pin (dsPIC30F3012) and 28-pin (dsPIC30F3013) packages, and are targeted at sensor processing or other applications that can benefit from high performance in a small form factor, said Microchip.

"Many applications can benefit from the ability to place a high-performance dsPIC30F node in a tight space," said Sumit Mitra, VP of Microchip's Digital Signal Controller Division. "These two new dsPIC30F devices enable engineers to make small products smarter."

The new dsPIC DSC combines the performance of a 16-bit Flash microcontroller (MCU) with the computation and throughput capabilities of a digital signal processor (DSP). The company added that the dsPIC DSCs have the "heart" of a 16bit MCU with robust peripherals and fast interrupt handling capability, and the "mind" of a DSP that manages high-computation activities, creating the optimum single-chip, single-instruction-stream solution for embedded system designs.

Both the dsPIC30F3012/3013 are able to operate from 2.5V to 5.5V. Additional features include 2KB of SRAM and 1KB of high-endurance EEPROM data memory; 12-bit analog-to-digital converter with up to 10 signal channels and 200K samples-per-second; and three 16-bit timers; SPI, I?C and up to two UARTs (1 UART on dsPIC30F3012). In addition, Microchip's Enhanced Flash self-programming capability permits remote upgrades to the Flash program memory, allowing code revisions in end-users' applications.

All dsPIC30F DSCs use the same MPLAB Integrated Development Environment (IDE) shared by the company's PIC MCU family, and are supported by Microchip's high-performance development systems, including MPLAB C30 C Compiler, MPLAB SIM 30 Software Simulator, MPLAB ICD 2 In-Circuit Debugger, MPLAB ICE 4000 In-Circuit Emulator and MPLAB Visual Device Initializer.
