General description

The SC18IS602/602B and SC18IS603 are designed to serve as an interface between a standard I2C-bus of a microcontroller and an SPI bus. This allows the microcontroller to communicate directly with SPI devices through its I2C-bus. The SC18IS602/602B/603 operates as an I2C-bus slave-transmitter or slave-receiver and an SPI master. The SC18IS602/602B/603 controls all the SPI bus-specific sequences, protocol, and timing.

Features

■ I2C-bus slave interface operating up to 400 kHz

■ SPI master operating up to 1.8 Mbit/s (SC18IS602/602B) or 4 Mbit/s (SC18IS603)

■ 200-byte data buffer

■ Up to four slave select outputs

■ Up to four programmable I/O pins

■ Operating supply voltage: 2.4 V to 3.6 V

■ Low power mode

■ Internal oscillator option

■ Active LOW interrupt output

■ ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101

■ Latch-up testing is done to JEDEC Standard JESD78 that exceeds 100 mA

■ Very small 16-pin TSSOP

Applications

■ Converting I2C-bus to SPI

■ Adding additional SPI bus controllers to an existing system
