The folks at Microchip
have just announced from the DESIGN East/ESC Boston Conference the expansion of their 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 4x4 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.
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 60x8 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.”Development support
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. Further documentation and information is available from Microchip’s USB
Design Centers.Pricing and availability
Pricing starts at $0.50 each in high volumes. The PIC16F145X family is available now for sampling, and volume production is expected in Mid October. The PIC16F1454 and PIC16F1455 are offered in 14-pin SOIC, TSSOP and PDIP, as well as 4x4 mm 16-pin QFN packages, while the PIC16F1459 is available in 20 pins with the same package types and sizes.
The three-member PIC18FXXK50 family is available now for sampling, and volume production is expected in Early November. The PIC18F24K50 and PIC18F25K50 are offered in 28-pin SOIC, SSOP, SPDIP and 6x6 mm QFN packages, while the PIC18F45K50 is available in 44-pin TQFP, as well as 40-pin PDIP and 5x5 mm UQFN packages.
Finally, all nine members of the PIC18F97J94 family are expected to be available for sampling in October, and volume production is expected in Early November. The PIC18F65J94, PIC18F66J94 and PIC18F67J94 are offered in 64-pin TQFP and QFN packages. The PIC18F85J94, PIC18F86J94 and PIC18F87J94 are available in the 80-pin TQFP package. The PIC18F95J94, PIC18F96J94 and PIC18F97J94 are available in the 100-pin TQFP package.
