DS31037B-page 9 PIC24F16KL402 FAMILY 1.0 DEVICE OVERVIEW This document contains device-specific information for the following devices: The PIC24F16KL402 family adds an entire range of economical, low pin count and low-power devices to Microchip’s portfolio of 16-bit microcontrollers. Aimed at applications that require low-power consumption but more computational ability than an 8-bit platform can provide, these devices offer a range of tailored peripheral sets that allow the designer to optimize both price point and features with no sacrifice of functionality. 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-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 PIC24F16KL402 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 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 The PIC24F16KL402 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. 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 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 the 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 helps in migrating to the next larger device. This is true when moving between devices with the same pin count, or even jumping from 20-pin or 28-pin devices to 44-pin/48-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. • PIC24F04KL100 • PIC24F04KL101 • PIC24F08KL200 • PIC24F08KL201 • PIC24F08KL301 • PIC24F08KL302 • PIC24F08KL401 • PIC24F16KL401 • PIC24F08KL402 • PIC24F16KL402 |
