Microcontrollers

8-Bit PIC® MicrocontrollersThe peripheral-rich 8-Bit PIC® Microcontrollers offer the best price/performance ratio in the industry, with Flash, one-time-programmable and ROM program memory options.Based on a powerful RISC core, these families feature a common architecture for easy migration from 6 to 100 pins with little or no code change required. Many of thesedevices feature CAN, Ethernet, USB and Motor Control functionality.

16-Bit PIC® MicrocontrollersThe 16-Bit PIC24 Microcontrollers build upon the performance, peripherals and features found in the 8-bit PIC18 family, offering up to 40 MIPS. When paired with theoptimized MPLAB® C30 C Compiler, PIC24 Microcontrollers provide the high throughput and C code density needed to achieve system performance goals and product launchschedules. The PIC24F and PIC24H Series are completely software and MPLAB® IDE compatible, providing easy migration as project requirements change, giving designengineers the ability to add performance and functionality to applications without sacrificing the initial investment and engineering resources. Many of these devices featureUSB and CAN functionality.

16-Bit dsPIC® Digital Signal Controllers (DSC)The 16-bit high-performance dsPIC DSCs combine the best features of microcontrollers with the best features of DSPs in a single core. With speeds of up to 40 MIPS, theyare designed for C programming efficiency, have Flash program memory, data EEPROM, powerful peripherals and a variety of software libraries. With a familiar microcontroller“feel” in tools and design environment, these dsPIC DSCs target motor control and power conversion, speech and audio, internet and modem connectivity, telecom,encryption, high-speed sensing and automotive applications. Many of these devices feature Motor Control and CAN functionality.

RISC-Based ArchitectureThe PIC Microcontroller architecture is based on a modified Harvard RISC instruction set that provides an easy migration path from 6 to 80 pins and from 384 bytes to128 Kbytes of program memory. By combining RISC features with a modified Harvard dual-bus architecture, Microchip’s fast and flexible 10 MIPS PIC18F core is the mostpopular architecture for new microcontroller designs. A simple instruction set and seamless migration between product families make PIC microcontrollers the logical choicefor designs requiring flexibility and performance.

PIC® Microcontroller Migration StrategyAs part of an inherent strategy to offer customers a low-risk development environment, the PIC® Microcontroller family offers easy migration within the complete range ofproducts. Migration between the different PIC® Microcontrollers enables several advantages such as future cost reductions, feature enhancements and late developmentchanges with minimal impact to the existing hardware, software and the engineering development environment. The PIC® Microcontroller family is pin compatible within agiven pin count as well as code compatible between the different architectures. This offers a seamless migration path between the different PIC® Microcontrollers thatprotects investments made in software development and design tools.

Low-Power nanoWatt TechnologyMicrochip’s proprietary nanoWatt Technology provides industry leading low-power operating voltage ranges and flexible power managed technology from DC up to 40 MHz.In fact, the typical PIC® Microcontroller with nanoWatt technology draws less than 50 nano-Amps in Sleep mode. Microchip has designed many of its nanoWatt technologymicrocontrollers to be fully operable with any supply rated between 2 volts and 5.5 volts. PIC® Microcontrollers with nanoWatt technology support up to nine oscillator modes.These include the option to select from two internal clock sources — a software configurable 8 MHz oscillator for normal operation and a 31 kHz oscillator for use when lowpower consumption is a necessity. Clock frequency can be switched on the fly, allowing the user to transition between external clocks and the internal oscillators with nodelay in code execution. A two speed start-up feature takes advantage of this seamless transition by running from either of the internal oscillators while an external clocksource stabilizes on start-up. After the external source has stabilized, the microcontroller automatically makes a clock switch, saving precious “up” time in applications withlow power budgets. nanoWatt technology microcontrollers allow design engineers to fine tune their system power consumption with several new power managed modes.These include configurable Idle and Sleep modes that let designers tailor current consumption levels and clocking options to fit any power budget, as well as an Ultra LowPower Wake-up (ULPW) mode that drastically reduces current draw during wake-up. Some devices include Low Power Timer 1 <1 µA for Real Time Clock.
