Microchip Technology

The dsPIC33F CPU has a 16-bit (data) modified Harvard architecture with an enhanced
instruction set, including significant support for digital signal processing. more

The PIC24F architecture specification was created as a powerful extension of Microchip’s existing RISC microcontroller portfolio. By giving users an even greater range of options for computational power and rich peripheral sets, it allows users to grow their applications.
At the same time, the architecture was tailored to keep as much of the existing PICmicro® MCU feature set and nomenclature as possible, making it easy for
applications to make the jump. more

Microchip’s PIC18 MCUs are ideal for applications requiring 10-16 MIPS performance, with up to 128KB program memory, ranging from 18-100 pins and include: C compiler efficiency, High performance architecture (16-bit program word), Flexibility of self programming Flash, Industry leading peripherals and firmware including CAN, USB, ZigBee™, TCP/IP. more

The high performance of the PIC12F devices can be attributed to a number of architectural features commonly found in RISC microprocessors. To begin with, the PIC12F devices use a Harvard architecture in which program and data are accessed on separate buses. This improves bandwidth over traditional von Neumann architectures where program and data are fetched on the
same bus. Separating program and data memory further allows instructions to be sized differently than the 8-bit wide data word. more

The PIC10F220 is a low-cost, high-performance, 8-bit, fully-static Flash-based CMOS microcontroller. It employs a RISC architecture with only 33 single-word/ single-cycle instructions. All instructions are singlecycle (1 μs) except for program branches, which take two cycles. The PIC10F220 delivers performance in an order of magnitude higher than their competitors in the same price category. The 12-bit wide instructions are highly symmetrical, resulting in a typical 2:1 code compression over other 8-bit microcontrollers in its class. The easy-to-use and easy to remember instruction set reduces development time significantly. The PIC10F220 are also equipped with special features that reduce system cost and power requirements. more

Microchip’s dsPIC33E family of digital signal controllers (DSCs) features a 70 MIPS dsPIC® DSC core with integrated DSP and enhanced on-chip peripherals. more
