SC28L202A1DGG,518

SC28L202A1DGG,518 is a high-performance dual UART. Its functional and programming features closely match but greatly extend those of previous Philips dual-channel UARTs. Its configuration on power-up is similar to that of the SC26C92. Its differences from the SC26C92 are the 256-character receiver, 256-character transmit FIFOs, 3V, and 5V compatibility, 8 I/O ports for each UART—16 total, arbitrating interrupt system, and overall faster bus and data speeds. It is fabricated in an advanced 0.5-micron CMOS process. It is a member of the IMPACT® line of data communications parts pin programming that will allow the device to operate with either the Motorola or Intel bus interface by changing the function of some pins (reset is inverted, DACKN, and IACKN enabled for example).
