High-Performance 16-bit Microcontroller and DSC Families from Microchip

Microchip has announced two high-performance (40MIPS), low pin count (18- and 28-pin) 16-bit product families – the PIC24HJ12GP family of microcontrollers and the dsPIC33FJ12GP family of Digital Signal Controllers. Both families feature Peripheral Pin Select capability, which allows designers to re-map digital I/O – allowing designers to use smaller pin count devices, minimise board space, and optimise board layout to reduce noise.

With their small size, low price and high-performance, the new dsPIC33FJ12GP DSCs are ideally suited to smart sensor applications – locating the processor with the actual sensor, thereby reducing noise and simplifying system design.

The dsPIC33FJ12GP’s on-board 1.1 Msps A-to-D converter can provide signal over-sampling, while the processor can implement digital filtering and spectral analysis adjacent to the actual sensor.

Both new families are supported by the full range of Microchip tools, 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 density, along with maths and peripheral

libraries. For emulation and debugging, Microchip offers the full-featured MPLAB REAL ICE™ tool and the low-cost MPLAB ICD 2 tool. The new 16-bit 28-pin starter board (part # DM300027) can be used for development with any of Microchip’s 28-pin 16-bit microcontroller and DSCs. In addition, for the dsPIC families, the low-cost Digital Filter Design tool and free dsPICworksTM software allows designers to readily specify, simulate and create digital filters.

The four new devices are all available now for general sampling and volume production. The PIC24HJ12GP201 and dsPIC33FJ12GP201 are available in 18-pin SOIC and SDIP packages, and the PIC24HJ12GP202 and dsPIC33FJ12GP202 are available in 28-pin SOIC, QFN and SDIP packages.

The new families add to Microchip’s 92 different 16-bit microcontrollers and DSCs offering seamless migration and scalability with pin, peripheral, software and tool compatibility.
