60 MIPS controllers - 31 August 2011 - Tempe Technologies

Microchip has launched its new (60 MIPS, 16-bit dsPIC digital signal controllers (DSCs) and PIC24 microcontrollers (MCUs). Based on a next-generation core, the dsPIC33 and PIC24 ‘E’ devices introduce more memory and higher integration compared to dsPIC DSCs and PIC24 MCUs with the previous-generation core. This includes 536 KB of Flash memory, 52 KB RAM, 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.

To support the first nine dsPIC33 and PIC24 ‘E’ devices, Microchip has launched two USB starter kits and five plug-in modules (PIMs) which 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.

Microchip’s dsPIC33E DSCs and PIC24E MCUs are fully compatible with the existing portfolio of dsPIC33F DSCs, PIC24H/PIC24F MCUs, software libraries and tools, providing a secure growth path for existing customers. The new USB 2.0

On-The-Go (OTG) peripheral enables a connection to a PC, Flash drive and other USB-enabled devices, whilst 60 MIPS performance means that the new devices support high-end industrial and commercial applications, such as servo motor control, solar inverters and running dual three-phase motors in parallel.

In addition, 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 as well as the number of external components required.

The first dsPIC33 and PIC24 ‘E’ devices include four SPI and four 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.
