SC16IS740/750/760

Single UART with I²C-bus/SPI interface, 64 bytes of transmit

and receive FIFOs, IrDA SIR built-in support

Rev. 05 — 16 November 2006

Product data sheet

1. General description

The SC16IS740/750/760 is a slave I²C-bus/SPI interface to a single-channel high

performance UART. It offers data rates up to 5 Mbit/s and guarantees low operating and

sleeping current. The SC16IS750 and SC16IS760 also provide the application with 8

additional programmable I/O pins. The device comes in very small HVQFN24, TSSOP24

(SC16IS750/760) and TSSOP16 (SC16IS740) packages, which makes it ideally suitable

for handheld, battery operated applications. This family of products enables seamless

protocol conversion from I²C-bus or SPI to and RS-232/RS-485 and are fully bidirectional.

The SC16IS760 differs from the SC16IS750 in that it supports SPI clock speeds up to

15 Mbit/s instead of the 4 Mbit/s supported by the SC16IS750, and in that it supports

IrDA SIR up to 1.152 Mbit/s. In all other aspects, the SC16IS760 is functionally and

electrically the same as the SC16IS750. The SC16IS740 is functionally and electrically

identical to the SC16IS750, with the exception of the programmable I/O pins which are

only present on the SC16IS750.

The SC16IS740/750/760’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 SC16IS740/750/760 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.
