USB Flash Microcontrollers

 

Microchip Technology Inc. 
 
 Low-Cost Feature-Rich USB 8-bit Flash Microcontrollers 
 
 
 Supported 8-bit Architectures: PIC® Microcontrollers

The PIC18F13K50 and PIC18F14K50 (PIC18F1XK50) are the lowest-cost USB Flash microcontrollers from Microchip and provide a host of features not normally found on inexpensive 8-bit MCUs—enabling the addition of embedded USB into a wide range of applications. The new devices are supported by Microchip’s free USB software stack and the free MPLAB® IDE Integrated Development Environment, which provides a consistent development platform across all PIC® MCUs. This offers design engineers a solid migration path to higher levels of performance and functionality.

The PIC18F1XK50 MCUs include a host of serial communications interfaces, such as USB 2.0, I2C™, SPI and USART; enabling them to transfer data between USB and other embedded serial networks. Additionally, they provide a 10-bit, 9-channel ADC and dual comparators with S/R Latch, giving users the capability to process a variety of environmental inputs.

The PIC18F8493 LCD microcontroller family offers integrated LCD drive capability for low-power display applications. The devices feature 8 to 16 Kbytes of Flash program memory in 64- and 80-pin TQFP packages.

Additional features onboard 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. These MCUs can also be internally or externally clocked with seamless on-the-fly switching, bringing further power savings to the user. Furthermore, with an operating voltage range of 1.8 - 5.5V, the MCUs are designed for use in a wide variety of operating environments and power supplies, including batteries, USB interfaces or other power sources.

FEATURES & BENEFITS
Free USB 2.0 Host Stack, Device Stack, Class Drivers and Source Code
The PIC18F13K50 has 8 KB Flash and 512 Bytes of RAM memory, and the PIC18F14K50 has 16 KB Flash and 768 Bytes of RAM. Both have 256 Bytes of EEPROM for non-volatile data storage.
Low-power options are available for both devices (PIC18LF1XK50) offering 1.8 - 3.6V operation, with reduced power consumption for extremely powersensitive applications.
