Original Press Release:
Microchip Technology Adds More Flash Memory to the World's Smallest Low Cost Digital Signal Controllers
Six New dsPIC33F Low Pin Count Digital Signal Controllers Feature up to 32 Kbytes Flash Memory; Packages as Small as 6x6mm
CHANDLER, Ariz., Nov. 27, 2007 [NASDAQ: MCHP] - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced an expansion of its low pin count 16-bit Digital Signal Controller (DSC) portfolio with the addition of three dsPIC33F General Purpose Family members and three dsPIC33F Motor Control/Power Conversion Family DSCs, which offer increased memory options for a range of applications including smart sensor processing, advanced motor control, lighting and power inverters.
The new General Purpose DSCs feature 16 or 32 Kbytes of Flash memory with 28- or 44-pin packages and provide a pin- and code-compatible migration path for PIC24 microcontrollers. The devices also feature an on-chip Analog-to-Digital-Converter (ADC), with up to 1.1 Msps, and serial interfaces such as I2C(TM), SPI and UART. These DSCs are expected to be popular for a variety of embedded applications where high performance and small footprint are key requirements.
The three dsPIC33F Motor Control Family DSCs add a motor-control PWM with two independent clock sources for advanced motor control or inverter algorithms-as well as active power factor correction-using a single DSC. This on-chip PWM peripheral is also designed for power-conversion and lighting applications. They also include a quadrature encoder interface for sensor-based motor applications. These devices provide an excellent platform for advanced motor control algorithms, such as Field-Oriented Control (FOC)-bringing the next level of high performance, low noise and power efficiency to motor control applications. (Microchip's FOC source code can be downloaded for free, via Application Note AN1078, at www.microchip.com.)
Both the General Purpose and Motor Control DSCs also feature Peripheral Pin Select, which allows designers to remap digital I/O to optimize board layout-enabling smaller boards, less noise and the use of a lower pin count DSC.
"The unique combination of 32 Kbytes of Flash memory, DSP capability, low cost, and the industry's smallest DSC package creates powerful possibilities for today's embedded designers to push their products a step ahead of their competition," said Sumit Mitra, vice president of Microchip's Digital Signal Controller Division. "We have developed a number of basic and advanced libraries to aid time to market and to permit DSP-enabled features to be added without full immersion in DSP technology."
Microchip offers powerful applications libraries that can be downloaded from Microchip's Web site for free for evaluation and development. For production, libraries are either free or low cost, and without royalties. Library downloads include speech processing, noise reduction, motor control, advanced security, connectivity, file management, and common math and DSP routines. Microchip also offers low-cost visual tools for designers who wish to incorporate digital filters, tune parameters in real time and initialize peripherals.
Additional key features include the following:
Both Families
o 40 MIPS performance in 6x6 mm packages
o 32 or 16 Kbytes of Flash and 2 Kbytes of RAM
o 1 UART, 1 SPI and 1 I2C Port
dsPIC33FJ32GP General Purpose Family
o ADC w/ up to 13 channels, and user-selectable 10-bit or 12-bit mode
(10-bit mode enables simultaneous sampling, eliminating lag time between samples)
dsPIC33FJ32MC Motor Control/ Power Conversion Family
o ADC w/ up to 9 channels, and user-selectable 10-bit or 12-bit mode
(10-bit mode enables simultaneous sampling, eliminating lag time between samples)
Development Support
In addition to the aforementioned software libraries, both families are supported by the full complement of tools that are common to all of Microchip's controllers, including the free MPLAB® Integrated Development Environment with its Visual Device Initializer component, which graphically assists designers in mapping pins and initializing code for the on-chip Peripheral Pin Select pin-mapping function. The MPLAB C30 C compiler provides industry-leading code densities, along with math and peripheral libraries. For emulation and debugging, Microchip offers the full-featured MPLAB REAL ICE(TM) tool and the low-cost MPLAB ICD 2 tool. Finally, the 16-bit 28-pin starter board (part # DM300027) can be used for development with any of Microchip's 28-pin 16-bit microcontrollers and DSCs, while the 44-pin family members are supported with a plug-in module for the Explorer 16 Development Board (part # DM240001).
Pricing & Availability
The dsPIC33FJ32GP and dsPIC33FJ32MC families consist of three members each, which are all available today for general sampling and volume production with prices starting at $2.51 and $2.47 each, respectively, in 10,000-unit quantities. The dsPIC33FJ32GP202 and dsPIC33FJ32MC202 are available in 28-pin SDIP, SOIC and QFN packages. The dsPIC33FJ32GP204, dsPIC33FJ32MC204, dsPIC33FJ16GP304 and dsPIC33FJ16MC304 are all available in 44-pin TQFP and QFN packages.
