Microchip Technology Inc. has beefed-up its family of 16-bit dsPIC digital signal controllers (DSCs) with two devices that offer performance speeds of 30MIPS, self-programming capabilities via flash memory, and industrial and extended temperature ranges.

The dsPIC30F5015 and dsPIC30F5016 DSCs feature a PWM designed for power-conversion, motor-control and lighting applications; an associated 1MSPS 10bit ADC; 66KB of flash program memory; and full-speed operation using an internal oscillator (no crystal required). The DSCs are offered in 64-pin (dsPIC30F5015) and 80-pin (dsPIC30F5016) packages, and are suitable for applications that drive power FETs and require advanced algorithmic processing. Microchip's dsPIC DSCs combine the performance of a 16-bit flash microcontroller (MCU) with the computation and throughput capabilities of a digital signal processor.

Microchip's Enhanced flash self-programming capability permits a remote upgrade to the flash program memory, allowing code revisions in end-users' applications. The dsPIC30F5015 and dsPIC30F5016 operate from 2.5V to 5.5V, which is valuable for analog noise immunity or minimizing voltage-translation logic.

Additional key features include 66KB of flash program memory, which can typically withstand 100,000 erase/write cycles and has 40-plus years of data retention over a wide operating-voltage and temperature range, 2KB of SRAM, 8-output PWM, with complementary or independent modes, 4 duty-cycle generators and programmable dead time, 10bit ADC with up to 16 signal channels, 1MSPS, 4 sample and holds for simultaneous sampling, and trigger option from advanced PWM. There are four standard PWMs as well as CAN, SPI, I2C and UART peripherals.

All dsPIC30F DSCs use the same MPLAB Integrated Development Environment (IDE), which contains a motor-control GUI and is shared by Microchip's PIC MCU family. Additionally, the dsPIC30F is 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.

The dsPIC30F5015 and dsPIC30F5016 are available for general sampling and volume production in RoHS-compliant, 64- and 80-pin TQFP packages, respectively. Unit pricing in 10,000-piece quantities starts at $6 each for the dsPIC30F5015, and $6.47 each for the dsPIC30F5016.
