Chandler-based Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, announced from the DESIGN East/ESC Boston Conference the expansion of its certified Full-Speed USB 2.0 Device PIC microcontroller portfolio with three new Enhanced Midrange 8-bit families comprising 15 scalable MCUs ranging from 14 to 100 pins with up to 128 KB of Flash. All feature internal clock sources with the 0.25% clock accuracy necessary for USB communication, which saves up to $0.15 by eliminating the need for an external crystal. Additionally, all three families are eXtreme Low Power compliant, with power consumption down to 35 µA/MHz Active and 20 nA in Sleep mode.
The 14- and 20-pin PIC16F145X MCUs are Microchip’s lowest-cost and smallest-form-factor USB MCUs to date. Available in packages as small as 4×4 mm and featuring a wide array of integrated peripherals, the three-member family enables embedded applications that require USB connectivity and capacitive touch sensing, such as pulse oxymeters, PC accessories and security dongles.
The PIC18F2X/4XK50 devices, available in 28- and 40/44-pins, offer a cost-effective, pin-compatible migration option for customers utilizing legacy PIC18 USB MCUs. The three family members feature 1.8-5V operation, and integrate a “Charge Time Measurement Unit” for higher performance cap-touch sensing as well as measurement in applications such as audio docks and data loggers.
The full-featured PIC18F97J94 family is Microchip’s first to offer integrated LCD control, RTCC with Vbat, and USB on a single 8-bit PIC microcontroller. Available in 64, 80 and 100 pins, the nine-member family offers a 60×8 LCD controller (for a total of 480 segments), which eliminates the need for an external controller in applications with large segmented displays. It also integrates a real-time clock/calendar with battery back-up for end products such as home-automation/security panels, handheld scanners and single-phase energy meters.
“Today’s broad announcement demonstrates our commitment to innovation in the 8-bit MCU market,” said Steve Drehobl, vice president of Microchip’s MCU8 Division. “No one else offers crystal-free USB microcontrollers from 14 to 100 pins with this level of integration and low power consumption.”
To help speed development times, the downloadable and open-source USB Framework within the free Microchip Library of Applications (MLA) includes USB drivers for many common USB classes, including HID, CDC, Mass Storage, Win-USB and Audio-MIDI. These drivers can be used with all 15 of the new PIC MCUs.
In addition to providing free USB software drivers and stacks, Microchip hardware development tools are available for purchase. The Low Pin Count USB Development Kit (part # DM164127, $39.99) is available now, for use with the PIC16F145X family. The PICDEM™ FS-USB Board (part # DM163025-1, $59.99) is expected to be available in October, for use with the PIC18FXXK50 family.
Full-Speed USB Plug-in Modules (PIMs) are expected to be available in November for the PIC18F97J94 and PIC18F87J94, at a cost of $45 each, that operate standalone or in conjunction with Microchip’s existing LCD Explorer Development Board (part # DM240314, $125) and PIC18 Explorer Development System (part # DV164136, $165), respectively.
