Microchip Technology Inc. has a new family of 8bit PIC MCUs for USB applications. The PIC18F13K50 and PIC18F14K50 (PIC18F1XK50) are the lowest-cost USB MCUs from Microchip and provide a host of features.

"The introduction of the PIC18F1XK50 USB family exemplifies Microchip's commitment to remain at the forefront of the embedded marketplace," said Steve Drehobl, vice president of Microchip's security, microcontroller and technology development division. "More and more, our customers are making USB the protocol of choice when connecting their embedded systems to the outside world. This PIC18 family allows them to add USB to their designs using a single MCU to perform both the communication and the primary application tasks."

The PIC18F1XK50 MCUs include a host of serial communications interfaces, such as USB 2.0, I2C, SPI and USART. The devices also provide a 10bit, 9-channel ADC and dual comparators with S/R Latch, which says Microchip, give users the capability to process a variety of environmental inputs, from temperature and humidity logging to capacitive touch-sensing.

The PIC18F13K50 has 8Kbyte flash and 512bytes of RAM memory, whereas the PIC18F14K50 has 16Kbyte flash and 768bytes of RAM. Both devices have 256bytes of EEPROM for non-volatile data storage. Low-power options are available for both PIC18LF1XK50 devices offering 1.8-3.6V operation, with reduced power consumption for extremely power-sensitive applications.

Other features on the PIC18F1XK50 MCUs include a USB host-detection capability, whereby the MCU can be configured to enter sleep or any other power-managed mode when a USB connection is not present. The new MCUs can also be internally or externally clocked with seamless on-the-fly switching.

The PIC18F1XK50 MCUs are all available in 20-pin SSOP, SOIC, PDIP and 5mm x 5mm QFN packages. The PIC18F13K50 and PIC18LF13K50 MCUs; the PIC18F14K50 and PIC18LF14K50 MCUs are available in 10,000-unit quantities.
