Microchip announced 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 memory.
All feature internal clock sources with the 0,25% clock accuracy necessary for USB communication, which eliminates the need for an external crystal. In addition, all three families feature Microchip’s eXtreme Low Power technology, 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 x 4 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 1,8–5 V 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 latter family also integrates a real-time clock/calendar with battery backup for end products such as home automation or security panels, handheld scanners and single-phase energy meters.
To help reduce development times, the downloadable and open-source USB Framework within the free Microchip library of applications 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 microcontroller.
A range of hardware development tools is also available.
