DS39996F-page 11 PIC24FJ128GA310 FAMILY 1.0 DEVICE OVERVIEW This document contains device-specific information for the following devices: The PIC24FJ128GA310 family adds many new fea- tures to Microchip‘s 16-bit microcontrollers, including new ultra low-power features, Direct Memory Access (DMA) for peripherals, and a built-in LCD Controller and Driver. Together, these provide a wide range of powerful features in one economical and power-saving package. 1.1 Core Features 1.1.1 16-BIT ARCHITECTURE Central to all PIC24F devices is the 16-bit modified Harvard architecture, first introduced with Microchip’s dsPIC® Digital Signal Controllers (DSCs). The PIC24F CPU core offers a wide range of enhancements, such as: • 16-bit data and 24-bit address paths with the ability to move information between data and memory spaces • Linear addressing of up to 12 Mbytes (program space) and 32 Kbytes (data) • A 16-element working register array with built-in software stack support • A 17 x 17 hardware multiplier with support for integer math • Hardware support for 32 by 16-bit division • An instruction set that supports multiple addressing modes and is optimized for high-level languages, such as ‘C’ • Operational performance up to 16 MIPS 1.1.2 nanoWatt XLP POWER-SAVING TECHNOLOGY The PIC24FJ128GA310 family of devices introduces a greatly-expanded range of power-saving operating modes for the ultimate in power conservation. The new modes include: • Retention Sleep, with essential circuits being powered from a separate low-voltage regulator • Deep Sleep without RTCC, for the lowest possible power consumption under software control •VBAT mode (with or without RTCC), to continue operation limited operation from a back-up battery when VDD is removed Many of these new low-power modes also support the continuous operation of the low-power, on-chip Real-Time Clock/Calendar (RTCC), making it possible for an application to keep time while the device is otherwise asleep. Aside from these new features, PIC24FJ128GA310 fam- ily devices also include all of the legacy power-saving features of previous PIC24F microcontrollers, such as: • On-the-Fly Clock Switching, allowing the selection of a lower-power clock during run time • Doze Mode Operation, for maintaining peripheral clock speed while slowing the CPU clock • Instruction-Based Power-Saving Modes, for quick invocation of Idle and the many Sleep modes. 1.1.3 OSCILLATOR OPTIONS AND FEATURES All of the devices in the PIC24FJ128GA310 family offer five different oscillator options, allowing users a range of choices in developing application hardware. These include: • Two Crystal modes • Two External Clock modes • A Phase Lock Loop (PLL) frequency multiplier, which allows clock speeds of up to 32 MHz • A Fast Internal Oscillator (FRC) (nominal 8 MHz output) with multiple frequency divider options • A separate Low-Power Internal RC Oscillator (LPRC) (31 kHz nominal) for low-power, timing-insensitive applications. The internal oscillator block also provides a stable reference source for the Fail-Safe Clock Monitor (FSCM). This option constantly monitors the main clock source against a reference signal provided by the inter- nal oscillator and enables the controller to switch to the internal oscillator, allowing for continued low-speed operation or a safe application shutdown. 1.1.4 EASY MIGRATION Regardless of the memory size, all devices share the same rich set of peripherals, allowing for a smooth migration path as applications grow and evolve. The consistent pinout scheme used throughout the entire family also aids in migrating from one device to the next larger, or even in jumping from 64-pin to 100-pin devices. The PIC24F family is pin compatible with devices in the dsPIC33 family, and shares some compatibility with the pinout schema for PIC18 and dsPIC30. This extends the ability of applications to grow from the relatively simple, to the powerful and complex, yet still selecting a Microchip device. • PIC24FJ64GA306 • PIC24FJ128GA306 • PIC24FJ64GA308 • PIC24FJ128GA308 • PIC24FJ64GA310 • PIC24FJ128GA310 |
