PIC24FV32KA304 FAMILY

1.0

DEVICE OVERVIEW

This document contains device-specific information for

the following devices:

• PIC24FV16KA301, PIC24F16KA301

• PIC24FV16KA302, PIC24F16KA302

• PIC24FV16KA304, PIC24F16KA304

• PIC24FV32KA301, PIC24F32KA301

• PIC24FV32KA302, PIC24F32KA302

• PIC24FV32KA304, PIC24F32KA304

The PIC24FV32KA304 family introduces a new line of

extreme low-power Microchip devices. This is a 16-bit

microcontroller family with a broad peripheral feature set

and enhanced computational performance. This family

also offers a new migration option for those

high-performance

applications

which

may

outgrowing their 8-bit platforms, but do not require the

numerical processing power of a digital signal processor.

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-bit 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 PIC24FV32KA304 family

incorporate a range of features that can significantly

reduce power consumption during operation. Key

features 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 users 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: There

are three instruction-based power-saving modes:

- Idle Mode: The core is shut down while leaving

the peripherals active.

- Sleep Mode: The core and peripherals that

require the system clock are shut down, leaving

the peripherals that use their own clock, or the

clock from other devices, active.

- Deep Sleep Mode: The core, peripherals

(except RTCC and DSWDT), Flash and SRAM

are shut down.

1.1.3

OSCILLATOR OPTIONS AND

FEATURES

The PIC24FV32KA304 family offers 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.

• Two Fast Internal oscillators (FRCs): One with a

nominal 8 MHz output and the other with a

nominal 500 kHz output. These outputs can also

be divided under software control to provide clock

speed as low as 31 kHz or 2 kHz.

• A Phase Locked Loop (PLL) frequency multiplier,

available to the external Oscillator modes and the

8 MHz 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.
