Preliminary DS39905B-page 7 PIC24FJ256GA110 FAMILY 1.0 DEVICE OVERVIEW This document contains device-specific information for the following devices: This family expands on the existing line of Microchip‘s 16-bit general purpose microcontrollers, combining enhanced computational performance with an expanded and highly configurable peripheral feature set. The PIC24FJ256GA110 family provides a new platform for high-performance applications which have outgrown their 8-bit platforms, but don’t require the power of a digital signal processor. 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. 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 64 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 POWER-SAVING TECHNOLOGY All of the devices in the PIC24FJ256GA110 family incorporate a range of features that can significantly reduce power consumption during operation. Key items include: • On-the-Fly Clock Switching: The device clock can be changed under software control to the Timer1 source or the internal, low-power RC oscillator during operation, allowing the user to incorporate power-saving ideas into their software designs. • Doze Mode Operation: When timing-sensitive applications, such as serial communications, require the uninterrupted operation of peripherals, the CPU clock speed can be selectively reduced, allowing incremental power savings without missing a beat. • Instruction-Based Power-Saving Modes: The microcontroller can suspend all operations, or selectively shut down its core while leaving its peripherals active, with a single instruction in software. 1.1.3 OSCILLATOR OPTIONS AND FEATURES All of the devices in the PIC24FJ256GA110 family offer five different oscillator options, allowing users a range of choices in developing application hardware. These include: • Two Crystal modes using crystals or ceramic resonators. • Two External Clock modes offering the option of a divide-by-2 clock output. • A Fast Internal Oscillator (FRC) with a nominal 8 MHz output, which can also be divided under software control to provide clock speeds as low as 31 kHz. • A Phase Lock Loop (PLL) frequency multiplier, available to the external oscillator modes and the FRC oscillator, which allows clock speeds of up to 32 MHz. • A separate internal RC oscillator (LPRC) with a fixed 31 kHz output, which provides a low-power option for timing-insensitive applications. The internal oscillator block also provides a stable reference source for the Fail-Safe Clock Monitor. This option constantly monitors the main clock source against a reference signal provided by the internal 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 and PIC32 families, and shares some com- patibility 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. • PIC24FJ128GA106 • PIC24FJ128GA110 • PIC24FJ192GA106 • PIC24FJ192GA110 • PIC24FJ256GA106 • PIC24FJ256GA110 • PIC24FJ128GA108 • PIC24FJ192GA108 • PIC24FJ256GA108 |
