Philips Introduces Industry's First UART With Real Time Data Error Detection and 256 Byte FIFO.Business Editors/High-Tech Writers DesignCon 2004 SANTA CLARA, Calif.--(BUSINESS WIRE)--Feb. 2, 2004 SC28L202 offers High Speed, Low Power and Dual Channels Ideal for Portable and Handheld Applications To support the ever-increasing speed and complexity in today's designs, Royal Philips Electronics (NYSE NYSE See: New York Stock Exchange :PHG) (AEX AEX See: Amsterdam Exchange :PHI) today announced the industry's first Universal Asynchronous Receiver/Transmitter (communications, hardware) Universal Asynchronous Receiver/Transmitter - (UART) An integrated circuit used for serial communications, containing a transmitter (parallel-to-serial converter) and a receiver (serial-to-parallel converter), each clocked separately. (UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice ) with 256 Byte FIFO (First In First Out) A storage method that retrieves the item stored for the longest time. Contrast with LIFO. See traffic engineering methods. FIFO - first-in first-out 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 C 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 (algorithm) cyclic redundancy check - (CRC or "cyclic redundancy code") A number derived from, and stored or transmitted with, a block of data in order to detect corruption. and longitudinal redundancy from the CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. . 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 C degrees at commercial pricing and with pin programming for a variety of bus applications. Additional features of the SC28L202 UART include: -- 3-Character recognition -- Bus cycle times of 55ns at 3.3V and 5V -- 16 GP I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output for modem control, DMA -- Arbitrating interrupt -- Complete automatic 9-bit mode Xon/Xoff Pricing and Availability The SC28L202 UART is currently available in the TSSOP TSSOP Thin Shrink Small Outline Package TSSOP Thin Scale Small Outline Package 56 package for $6.00 USD USD In currencies, this is the abbreviation for the U.S. Dollar.
