Microchip Launches 60MIPS Enhanced dsPIC33 DSCs, PIC24 MCUs

Microchip Technology Inc. has announced its 60MIPS 16-bit dsPIC Digital Signal Controllers (DSCs) and PIC24 microcontrollers (MCUs). Based on the next-generation dsPIC DSC/PIC24 MCU core, the 60 MIPS dsPIC33 and PIC24 "E" devices offer larger (536kB) Flash memory, more RAM (52kB), greater I/O capability with 144-pin packages, a USB 2.0 OTG interface, and expanded motor-control, graphics, audio, and real-time embedded-control capabilities over the previous-generation dsPIC DSC/PIC24 MCU core.

In support of the first nine dsPIC33 and PIC24 "E" devices released, Microchip launched two USB starter kits and five Plug-In Modules (PIMs) that can be used with its Multimedia Expansion Board, motor-control development kits, and Explorer 16 development platforms. Also available are 30 software libraries and application notes on topics such as speech and audio, encryption/decryption, communications, and motor control. The new devices and comprehensive support package help customers create high-performance designs in less time.



Microchip's dsPIC33E DSCs and PIC24E MCUs are fully compatible with the existing broad portfolio of dsPIC33F DSCs and PIC24H/PIC24F MCUs, software libraries and tools, providing a solid growth path for current customers.

The new USB 2.0 On-The-Go (OTG) peripheral enables a connection to a PC, Flash drive and other USB-enabled devices, and 60MIPS performance means the new devices support high-end industrial and commercial applications, such as servo motor control, solar inverters, and running dual 3-phase motors in parallel. Additionally, a new, independent Pulse Width Modulation (PWM) mode supports multiple stepper motors and dead-time compensation, which reduces software overhead. Three on-chip analog comparators further reduce system cost and the number of external components required.

The first dsPIC33 and PIC24 "E" devices include four each of the SPI and UART interfaces, as well as two I2C interfaces. A new auxiliary Flash module enables designers to program or erase Flash data without slowing normal CPU operation, which is critical for motor-control, power-conversion and many other applications that require on-the-fly programming. Improved Direct Memory Access (DMA) functionality automatically starts linked DMA operations, and the improved debugger capability enables complex breakpoints for faster debugging. Additionally, with enhanced timer capabilities, the dsPIC33 and PIC24 "E" devices' Input-Capture and Output-Compare modules are more flexible and powerful.
