General description

The SC16IS752/SC16IS762 is an I2C-bus/SPI bus interface to a dual-channel high

performance UART offering data rates up to 5 Mbit/s, low operating and sleeping current;

it also provides the application with 8 additional programmable I/O pins. The device comes

in very small HVQFN32 and TSSOP28 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.

The SC16IS762 differs from the SC16IS752 in that it supports SPI clock speeds up to

15 Mbit/s instead of the 4 Mbit/s supported by the SC16IS752, and in that it supports IrDA

SIR up to 1.152 Mbit/s. In all other aspects, the SC16IS762 is functionally and electrically

the same as the SC16IS752.

The SC16IS752/SC16IS762’s internal register set is backward compatible with the widely

used and widely popular 16C450. This allows the software to be easily written or ported

from another platform.

The SC16IS752/SC16IS762 also provides additional advanced features such as auto

hardware and software ﬂow control, automatic RS-485 support and software reset. This

allows the software to reset the UART at any moment, independent of the hardware reset

signal.
