Royal Philips Electronics has disclosed that its SC28L202 device is the industry's first Universal Asynchronous Receiver/Transmitter (UART) with 256B FIFO and real-time error detection.

The newest member of the Impact line of communication devices, the product is a 2-channel UART operating at high speed with low power consumption, operating at both 3V and 5V over the -40C to 85C temperature range.

Suitable for use in portable and handheld applications, the SC28L202 is also targeted for use in telecom/networking, mobile communication/computing, consumer, industrial control, medical and security applications.

The UART has a real-time data error detection mode that ensures data integrity by offloading tasks such as parity check, cyclic redundancy check and longitudinal redundancy from the CPU. The 256-byte FIFO channels reduce the CPU overhead by minimizing the need for error interrupts (four to 16x less) as it allows for interrupt at any level for each FIFO.

The product is available in the TSSOP 56 package in quantities of 1,000.
