PIC24 with eXtreme Low Power 16-bit eXtreme Low Power (XLP) Products As more electronic applications require low power or battery power, energy conservations becomes paramount. Today’s applications must consume little power and in extreme cases last up to 15–20 years while running from a single battery. Products with Microchip’s eXtreme Low Power (XLP) technology offer the industry’s lowest currents for sleep, where most applications spend 90–99% of their time. Ideal for applications including portable medical devices, thermostats, energy monitoring, wireless sensors, energy harvesting and security applications. ■ eXtreme Low Power (XLP)—the Benchmark in Low Power! •    Down to 9 nA in Deep Sleep •    As low as 400 nA with RTCC active ■ Fast wake-up from Deep Sleep •    Minimize CPU run time •    Flexible wake-up sources ■ Effi cient instruction set; 90% single-cycle instruction •    Active mode currents as low as 150 μA/MHz •    CoreMark™/MHz of 1.88, 12.53 CoreMark/mA Software & App Notes XLP Battery Life Estimator The XLP Battery Life Estimator is a free software utility to aid you in developing Low Power applications. The tool estimates average current consumption and battery life. The utility allows users to select the target device, battery type, the application’s operating conditions (such as voltage and temperature) and model the active and power-down times for their applications. The tool comes pre-loaded with specifications of Microchip’s PIC microcontrollerss featuring nanoWatt XLP technology and commonly used batteries in embedded applications. Low Power Design Guide: A single source for low power consumption from the viewpoint of the MCU (Application Note AN1416) nanoWatt XLP Technology: An Introduction to Microchip’s Low-Power Devices (Application Note AN1267) 4 16-bit Embedded Control Solutions Development Tools nanoWatt XLP 16-bit Development Board (DM240311) The XLP 16-bit Development Board is designed with eXtreme Low Power in mind. Designed as a true platform for low power development, it enables designs with sleep currents as low as 9 nA. The board is suitable for prototyping many low power applications including RF sensors, data loggers, temperature sensors, electronic door locks, metering sensors, remote controls, security sensors, smart cards and energy harvesting. The PICtail™ interface supports Microchip’s extensive line of daughter cards for easy evaluation of your next low power application. MPLAB® REAL ICE™ In-Circuit Emulator Power Monitor (AC244008) This add-on board fills the need for low power monitoring and debugging which allows for breakpoints when current exceeds a specified threshold and provides graphs of current, voltage and time versus code execution. Also helpful for debugging code with time-stamping with 100 ns resolution. Outperforming the Competition Industry standard CoreMark™ benchmarks show that PIC24F outperforms M0, M0+ and MSP430 cores. By having higher CoreMark, lower current and smaller code size, the PIC24F performs more work per mA of current consumed. 15 12 9 6 3 0 PIC24F/dsPIC33F 12.53 Cortex-M0 10.12 Cortex-M0+ 12.4 CoreMark/mA Featured XLP Products PIC® MCU with XLP Technology Flash (KB) Pins Sleep (nA) Deep Sleep (nA) WDT (nA) 32 kHz SOSC/RTCC (nA) μA/MHz PIC24F16KL402 4–16 14/20/28 30 – 210 690 150 PIC24FJ64GB004 32–64 28/44 200 20 200 500 250 PIC24FJ128GA310 64–128 64/100 330 10 270 400 150 www.microchip.com/xlp
