Today's portable products need to operate longer with less power and more functionality. The new PIC XLP microcontrollers contain features that are ideally suited for applications such as remote sensors powered by energy harvesting or sealed-battery applications, enabling them to run for up to 20 years from a single battery. Additionally, the lower price and smaller footprint of these new devices make them even easier to integrate into space-constrained products where low power and low cost are of primary concern.
The key to the PIC24F04KA201 MCUs' 20 nA sleep currents is Deep Sleep mode. By isolating power to various circuits during sleep, Deep Sleep mode reduces power consumption to a minimum. Additionally, Deep Sleep gives designers the flexibility to customize their applications for the lowest power consumption through multiple internal wake-up sources, such as Brown-Out Resets, interrupts and Watch-dog Timers, all while maintaining the I/O states.
"Microchip is committed to providing the world's lowest power consumption, with more than 50 PIC MCUs featuring nanoWatt XLP technology now in production," said Mitch Obolsky, vice president of Microchip's Advanced Microcontroller Architecture Division. "The PIC24F04KA201 16-bit family is the latest result of this commitment, offering the lowest cost and lowest pin count PIC24, while maintaining the world's lowest sleep currents."
Example applications for the new PIC24F04KA microcontrollers include: Medical (portable and home medical devices, oxygen flow meters, lifestyle/fitness monitors); Industrial (energy harvesting/scavenging, water/gas/heat meters, portable gas sensors, remote sensor networks, asset tracking, sealed/harsh environment sensors); and Consumer (security-system dongles, sealed disposable electronics, portable electronics, smart cards).
"The extremely low sleep current and numerous wake-up features of Microchip's new PIC XLP microcontrollers should be ideal for battery-operated devices, which actually spend most of the time asleep," said Tom Starnes, embedded processor analyst at the semiconductor research firm Objective Analysis. "The interest in the market for such low-power processors, for use in consumer to industrial applications, is really on the rise."
In addition to being ideal for low-power and space-constrained applications, the PIC24F04KA201 MCU family has high C-code efficiency and computational horsepower, which makes it well suited for applications requiring advanced algorithms. Other key features include:
- Up to 16 MIPS operation using 32 MHz internal clock
- 4 Kbytes Flash, and 512 bytes SRAM
- 10-bit, up to 9 channel, 500 Ksps ADC
- mTouch Capacitive Touch Sensing Peripheral
- 2 Rail-to-Rail Comparators
- SPI, I2C and UART modules for serial communications
Owners of the Explorer 16 development board can purchase a $25 PIC24F16KA plug-in module (part # MA240017), for development with this new 16-bit family. All PIC XLP microcontrollers are supported by Microchip's development tools, including the free MPLAB IDE, the MPLAB REAL ICE emulation system, the MPLAB ICD 3 in-circuit debugger, the PICkit 3 low-cost debugger/programmer and Microchip's free C compilers.
