    Microchip’s new line of PIC24F 20 and 28-pin Extreme Low-Power (XLP) microcontrollers, including the PIC24F16KA102 and PIC24FJ64GA102 families. The XLP 16-bit board permits users to explore and evaluate extreme low-power features, and learn low-power software and hardware techniques. Various headers are available to measure both microcontroller and component power consumption.

  • Page 16: Using The Development Board Out Of The Box

    XLP 16-Bit Development Kit User’s Guide USING THE DEVELOPMENT BOARD OUT OF THE BOX Although intended as a development platform, the XLP 16-bit board may also be used directly from the box as a demonstration platform for the preprogrammed PIC24F16KA102 microcontroller.

  • Page 17: Chapter 2. The Xlp Demonstration Application

    Installing the Software and Driver Before connecting the board to the PC for the first time, install the USB Serial Converter driver. The instructions for this process are provided with the XLP 16-bit Development Kit source code distribution, which is available at: http://www.microchip.com/xlp16bitboard.

    At this point, the terminal is connected to the XLP board and communicating through the emulated serial port. It may be necessary to press S1 (Master Clear) to reset to the PIC24F microcontroller and obtain a display.
  • Page 19 The XLP Demonstration Application On power-up, the PIC24F16KA102 device will wake-up every 10 seconds from a Real-Time Clock Calendar (RTCC) interrupt, then re-enter Sleep mode. While awake, the microcontroller takes a temperature measurement using the MCP9700 tempera- ture sensor and writes the information to the serial EEPROM. Status information is displayed, including the wake-up source, Low-Power mode, selected sensor, data EEPROM information and current temperature.

  • Page 21 Sleep and Idle modes for the PIC24F microcontroller. In Deep Sleep, most micro- controller functions are disabled to minimize power consumption. The available wake-up sources supported by the XLP 16-Bit Development Kit are the RTCC interrupt, External Interrupt 0 (INT0) and MCLR Reset. When Idle mode is selected, all peripherals continue to operate;...
  • Page 22 XLP 16-Bit Development Kit User’s Guide • DEFAULT_MODE sets the default Low-Power mode, selecting between Sleep, Deep Sleep and Idle modes. If held-button detection is enabled, the Low-Power mode can be changed at run time; otherwise, the selected mode is always used.

    This chapter provides a more detailed description of the hardware features of the XLP 16-Bit Development Kit. HARDWARE FEATURES The key features of the XLP 16-bit board are listed below. They are represented in the order given in Section 1.4 “Development Board Features”...
  • Page 24 3.2.3 Power Sources The XLP 16-bit board can use any one of six power options for full operation: 1. Bus power via the USB connector (J9). This provides a nominal 5V power source, regulated to approximately 3.3V for the microcontroller and board com- ponents, through a Schottky diode and Low Dropout (LDO) regulator circuit (D7, Q1).
  • Page 25 3.2.3.4 ON-CHIP REGULATOR CONFIGURATIONS (PIC24F J-SERIES) The XLP 16-bit board supports multiple regulator configurations for PIC24F devices with an internal voltage regulator. A slider switch (S4) allows the user to configure the board for either J-series or K-series Flash devices. With switch, S4, in the “PIC24FJ”...
  • Page 26 In many capacitive touch applications, an overlay is used to protect the PCB. Mounting holes are provided to secure overlay materials for evaluation. The low pin count devices, supported by the XLP 16-bit board, require that the touch pads be multiplexed with other board components. Specifically, CT2 is multiplexed with the temperature sensor circuitry, while CT3 is shared with the “Cap Sense”...
  • Page 27 The XLP 16-bit board also implements a conventional junction diode connected to an analog input to demonstrate low-cost temperature sensing. The Charge Time Measurement Unit (CTMU) provides a specified current to the diode; an A/D conver- sion determines the voltage across the diode.
  • Page 28 3.2.14 RS-232 Serial Port Options The XLP 16-bit board supports two types of RS-232 transceivers and associated sup- port circuitry through a standard DB9 connector. This port is configured as a DCE device and can be connected to a PC using a straight-through cable. Hardware flow control is not supported.

    C bus in their application. CURRENT MEASUREMENT One of the great advantages of the XLP 16-bit board is its provisions for in-circuit current measurement. Using simple techniques and equipment, users can experiment directly with low-power hardware and software techniques, then directly measure their current consumption without introducing measurement induced artifacts.
  • Page 30 3.3.3 Ammeter Tool Header The XLP 16-bit board includes a special 7-pin header (J10) for current measurement. The PIC MCU PWR and IC PWR jumpers (JP9 and JP10) ensure continuity of power when connecting or disconnecting a current measurement device. Microchip provides an optional XLP Current Measurement Cable (part number AC002023) as a convenient way of connecting the header to an ammeter.
