percent (typically pronounced as "choose") is a family of microcontrollers made by means of Microchip generation, derived from the PIC1650[1][2][3] originally advanced with the aid of wellknown tool's Microelectronics department. The call percent initially cited Peripheral Interface Controller.[4][5] the primary parts of the family were to be had in 1976; through 2013 the enterprise had shipped greater than twelve billion character components, used in a extensive kind of embedded structures.
Early models of % had examine-handiest reminiscence (ROM) or discipline-programmable EPROM for program storage, a few with provision for erasing reminiscence. All cutting-edge fashions use flash memory for software storage, and newer fashions permit the percent to reprogram itself. software memory and information reminiscence are separated. data reminiscence is 8-bit, 16-bit, and, in cutting-edge models, 32-bit huge. software instructions range in bit-count number via circle of relatives of %, and can be 12, 14, 16, or 24 bits lengthy. The education set also varies by means of model, with more powerful chips adding instructions for virtual signal processing functions.
The hardware capabilities of percent gadgets variety from 6-pin SMD, eight-pin DIP chips as much as 144-pin SMD chips, with discrete I/O pins, ADC and DAC modules, and communications ports including UART, I2C, CAN, or even USB. Low-electricity and high-pace versions exist for plenty kinds.
The producer resources computer software program for improvement called MPLAB, assemblers and C/C++ compilers, and programmer/debugger hardware under the MPLAB and PICKit collection. 0.33 birthday celebration and a few open-source equipment are also available. a few elements have in-circuit programming capability; low-fee improvement programmers are available as well as excessive-manufacturing programmers.
p.c devices are popular with each industrial developers and hobbyists due to their low cost, extensive availability, big user base, widespread collection of application notes, availability of low fee or unfastened improvement equipment, serial programming, and re-programmable Flash-memory functionality.
