Texas Instruments announced the universal asynchronous receiver/transmitters (UART) and controller area network lite (CAN-lite) programmable real-time unit (PRU) daughter cards and software. The UART PRU and CAN-lite PRU daughter cards can be used in evaluation with the AM1x Sitara ARM MPUs or as a standalone reference design. The daughter cards snap into the PRU peripheral connection on the AM1x Sitara ARM MPUs evaluation modules. The TI UART daughter card ($72) and the CAN daughter card ($77) are both available now. The production-quality software code for the daughter cards can be downloaded for free.
Mistral introduced UART and CAN daughter cards for Texas Instruments (TI) evaluation modules (EVMs) based on TI’s Sitara AM1x microprocessors (MPUs) and OMAP-L1x application processors for embedded industrial, medical and consumer designs. The UART daughter card has interfaces for soft UART, hard UART, and soft DIR. The CAN daughter card features soft CAN and hard CAN bus interfaces. The Mistral plug-in daughter cards help developers leverage the benefits of the PRU features on the AM1x and OMAP-L1x processors.
Microchip Technology introduced the MCP2200 USB-to-UART protocol converter. The MCP2200 is an out-of-the-box solution that makes it easy to add USB connectivity to embedded systems. By connecting the MCP2200 UART interface to any microcontroller UART peripheral, USB connectivity can be added. The MCP2200 includes 8 general-purpose I/O pins that can be controlled by the PC using the Windows-based configuration tool included with the MCP2200. The MCP2200 USB-to-UART protocol converter is available in 20-pin SSOP and SOIC packages for $1.39 each, in 10,000-unit quantities (for both package options). It is also available in a 5 mm x 5 mm QFN package, for $1.50 each, in 10,000-unit quantities.
