New Devices Have More Memory and Specialized Peripherals for Motor-Control and General-Purpose Applications with Op Amps, Temperature Sensing and Touch
Microchip Technology Inc. announced new additions to the 70 MIPS dsPIC33E and PIC24E product families, building on Microchip’s motor control and general-purpose device series that include integrated Op Amps and a Charge Time Measurement Unit (CTMU) for temperature sensing or mTouch capacitive touch sensing. The devices feature 70 MIPS of performance for motor control, sensing, actuators and other embedded applications. The new Digital Signal Controllers (DSCs) and microcontrollers include pin and feature compatible devices ranging from 32-256 KB of Flash memory, enabling designers to easily migrate within the family. These devices are also code compatible with Microchip’s existing dsPIC33F products, providing a migration path from 40 to 70 MIPS.
The new dsPIC33E and PIC24E devices (dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X, dsPIC33EPXXXMC50X and PIC24EPXXXGP20X, PIC24EPXXXMC20) enable motor control designers to reduce the costs of high-performance motor control systems with cost-effective 70 MIPS devices that include innovative technology. New on-chip peripherals, such as integrated Op Amps, reduce board space and the need for external components. These Op Amps can be used in a variety of sensing applications where signal amplification is required. With a rich feature set and low cost, the dsPIC33E and PIC24E devices can be used in sensor, communications, automotive, industrial and emerging applications.

Development Support
Microchip’s extensive suite of easy-to-use development tools is compatible with the dsPIC33E and PIC24E devices. For motor control, the low voltage dsPICDEM MCLV-2 Development Board (part # DM330021-2, $199) and high voltage dsPICDEM MCHV-2 Development System (part # DM330023-2, $699) are available today to provide designers with motor control development systems that enable customers to take full advantage of the internal Op Amps. Both motor control development boards use Plug-In Module (PIM) daughter cards which can be easily interchanged to support different configurations, with or without integrated Op Amps. Microchip offers two motor-control PIMs to support these development boards, the dsPIC33EP256MC506 External OpAmp Motor Control PIM (part # MA330031-2, $25) and the dsPIC33EP256MC506 Internal OpAmp Motor Control PIM (part #MA330031, $25), both of which are available today.
For customers developing applications other than motor control, Microchip offers the dsPIC33EP256GP506 General Purpose PIM (part # MA330030, $25), which is designed to work with Microchip’s modular Explorer 16 Development Platform.
Pricing & Availability
The dsPIC33E and dsPIC24E devices are available today for sampling and volume production, starting $1.80 each, in 10,000-unit quantities.
