Philips Debuts UART with Real Time Data Error Detection, 256 Byte FIFO

2/9/2004 - To support the ever-increasing speed and complexity in today’s designs, Royal Philips Electronics (NYSE: PHG, AEX: PHI) today announced the industry’s first Universal Asynchronous Receiver/Transmitter (UART) with 256 Byte FIFO and real time error detection. The SC28L202, the newest member of the Philips IMPACT line of communication devices, is a 2-channel UART operating at high speed with low power consumption – operating at both 3V and 5V over the –40 to +85 degree temperature range. These features make the SC28L202 ideal for use in portable and handheld applications where power requirements are a key consideration. Utilizing all of the features of the IMPACT line UARTs, the SC28L202 is also suitable for use in telecom/networking, mobile communication/computing, consumer, industrial control, medical and security applications.

Each device in the IMPACT family, including Philips’ newest UART device, is developed to suit several supply voltages, temperature ranges and bus architectures. This allows the SC28L202 UART to function in multiple applications, eliminating the need for design engineers to source eight different UARTs to suit each application. The SC28L202 UART has a unique 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 also significantly 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. In addition, the FIFO also meets the requirements for processing larger data packets.

"Signalogic is extremely happy the new SC28L202 UART has reached production," said Jeff Brower, president and engineering director at Signalogic, Inc. "This validates our original design choice and confidence in Philips. The FIFO depth is very important for our real-time system customers in areas such as telephony, VoIP, speech and acoustic audio. In some situations we can only deal with asynchronous I/O at packet boundaries, making temporary data storage at the chip level critical."

“Philips has a long history of innovation and leadership in industrial UARTs," said Pierre-Yves Lesaicherre, general manager, Interface Products Business Line in the semiconductors division of Philips. “The SC28L202 ensures the signal integrity, high performance and low power that provides our customers with an attractive solution that meets their current and future needs without increasing their cost of ownership.”

As part of Philips’ IMPACT line of UARTS, the SC28L202 ensures operation at 3.3V and 5V over a temperature range of -40 to +85 degrees at commercial pricing and with pin programming for a variety of bus applications.

Additional features of the SC28L202 UART include:

The SC28L202 UART is currently available in the TSSOP 56 package in quantities of 1,000.
