Microchip expands USB portfolio with fifteen new 8-bit PIC® MCUs

Microchip announces the expansion of its certified Full-Speed USB 2.0 Device PICо 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. In addition, all three families are eXtreme Low Power compliant, with power consumption down to 35 хA/MHz Active and 20 nA in Sleep mode. These crystal-free USB microcontrollers are the first to be offered with pin-counts ranging from 14 to 100 combined with such a high level of integration and low power consumption.
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 in addition to capacitive touch sensing, such as pulse oxymeters, PC accessories and security dongles.
The PIC18F2X/4XK50 devices, available in 28- and 40/44-pin packages, offer a cost-effective, pin-compatible migration option for customers using legacy PIC18 USB MCUs. The three family members feature 1.8-5V operation, and integrate a Charge Time Measurement Unit (CTMU) for higher performance capacitive-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-pin packages, 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. The family also integrates a real-time clock/calendar with battery back-up for end products such as home-automation or security panels, handheld scanners and single-phase energy meters.
