SC16IS762IPW,128 is an I²C-bus/SPI bus interface to a dual-channel high-performance UART offering data rates up to 5Mbit/s, low operating and sleeping current, it also provides the application with 8 additional programmable I/O pins. The device comes in very small packages, which makes it ideally suitable for hand-held, battery-operated applications. This chip enables seamless protocol conversion from I²C-bus/SPI to RS-232/RS-485 and is fully bidirectional. It differs from the SC16IS752 in that it supports SPI clock speeds up to 15Mbit/s instead of the 4Mbit/s supported by the SC16IS752, and in that it supports IrDA SIR up to 1.152Mbit/s. In all other aspects, the SC16IS762 is functionally and electrically the same as the SC16IS752. It is an internal register set that is backward compatible with the widely used and widely popular 16C450. This allows the software to be easily written or ported from another platform.
