Microchip expands usb portfolio with new 8bit PIC mcus

Microchip has expanded its usb 2.0 PIC microcontroller portfolio with three new midrange 8bit families, comprising 15 scalable mcus ranging from 14 to 100 pins with up to 128KB of Flash.

All devices are said to feature internal clock sources with the 0.25% clock accuracy necessary for usb communication, as well as being eXtreme Low Power compliant, with power consumption down to 35µA/MHz active and 20nA in sleep mode.

The company says the 14 and 20pin PIC16F145X mcus are its lowest cost and smallest form factor usb mcus to date. Available in 4x4mm packages, the family is optimised for embedded applications that require usb connectivity in addition to capacitive touch sensing, such as pulse oxymeters, pc accessories and security dongles.
