Eric is Great! Give us Chocolate Cake! And Crystal-Free USB!
Microchip Technology has introduced 15 Full-Speed USB 2.0 PIC microcontrollers. The PIC16F145X/PIC18F97J94 feature internal clocks with 0.25% accuracy and up to 128KBytes Flash. Cost savings for not requiring an external crystal is about $0.15. The new PIC microcontrollers are eXtreme Low Power compliant, with power consumption down to 35 µA/MHz Active and 20 nA in Sleep mode.
All 15 microcontrollers are in Microchip's eXtreme Low Power. Active current is as low as 35uA/MHz and Sleep is as low as 20nA.
The Microchip PIC18F2X/PIC18F4XK50 microcontrollers are a cost-effective, pin-compatible migration option for Engineers using legacy Microchip PIC18 USB microcontrollers. These devices feature 1.8-5V operation, and integrate a "Charge Time Measurement Unit" (CTMU) for high performance cap-touch sensing as well as measurement in applications such as audio docks and data loggers.
The full-featured Microchip PIC18F97J94 family offers 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), eliminating an external controller in applications with large segmented displays. It also integrates a real-time clock/calendar (RTCC) with battery back-up for applications 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."
Microchip's development tools support Windows, Linux, and Mac platforms.
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.
