April 9, 2009[Ideas For Design] Switching Circuit Increases Number Of USARTs Available From MCU
This design builds on a previously published Idea for Design (“Talk To Multiple Devices With One UART”). Our solution allows you to increase the number of USARTs (universal synchronous, asynchronous receiver/transmitters) available on a microcontroller with minimum hardware. Typical 8- and 16-bit microcontrollers have one programmable USART for communication. But designers...
February 14, 2008[Ideas For Design] Inexpensive MCU Replaces Dedicated Backup-Power Controller
Portable battery-powered applications sometimes also permit operation from the power grid. If so, the application must choose the appropriate available power source—the grid or the battery. If the battery is rechargeable, the system also requires a charging circuit. Instead of employing a dedicated charge controller for the backup-power controller, designers can choose the more economical option of using an inexpensive eight-pin microcontroller, available...
