MCUs: Microchip claims lowest sleep current in its new 16-bit MCUs


Chandler, Az. – Microchip Technology has just announced two new families of 16-bit low power, low pin count PIC24F microcontrollers (MCUs), one with USB functionality and one for general-purpose applications

Both incorporate the company's XLP technology, which has what the company claims is the world's lowest sleep currents, with current consumption down to 20 nA in Deep Sleep mode, resulting in the lowest power consumption of any MCU with USB OTG, 10 times lower than USB MCUs from other ultra-low-power manufacturers.

They are targeted at applications such as thumb-drive interfaces, capacitive touch panels and many battery-powered applications

According to Mitch Obolsky, vice president of Microchip's Advanced Microcontroller Architecture Division, the PIC24FJ64GA104 general-purpose family features nanoWatt XLP technology, 16 MIPS performance, 32 or 64 Kbytes of Flash, 8 Kbytes of RAM, a capacitive touch sensing peripheral, Real Time Clock and Calendar (RTCC), a 10-bit A/D, and the ability to reconfigure digital I/O pins via Peripheral Pin Select.

The PIC24FJ64GB004 family builds on these features with the world's easiest-to-use and most complete Full-Speed USB 2.0 Peripheral, Embedded Host and OTG solution. Both families are available in 28-pin QFN, SOIC and PDIP packages, and 44-pin QFN and TQFP packages.

Designers can purchase $25 plug-in modules (PIMs) for use with the Explorer 16 Development Board, for each of the new MCU families: PIC24FJ64GA104 PIM and PIC24FJ64GB004 PIM.

Additionally, the $60 USB PICtail Plus Daughter Board is available to enable USB development with the PIC24FJ64GB004 family, using the Explorer 16. All PIC24F microcontrollers are supported by Microchip's world-class 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.

All family members are available now for sampling and volume production. Prices start at $2.12 each in 10,000 unit quantities for the PIC24FJ64GA104 general-purpose family members, and $2.32 each in 10,000 unit quantities for the PIC24FJ64GB004 USB family members.
