SC18IS602BIPW/S8HP

The SC18IS602BIPW/S8HP from NXP Semiconductors is an integrated circuit designed to interface between a microcontroller's I2C-bus and an SPI bus. This allows a microcontroller to communicate directly with SPI devices using its I2C-bus. The device functions as an I2C-bus slave and an SPI master, managing all SPI bus-specific sequences, protocols, and timing.

Key features include an I2C-bus slave interface operating up to 400 kHz and an SPI master interface operating up to 1.8 Mbit/s. It possesses a 200-byte data buffer and supports up to four slave select outputs, which can also be configured as programmable I/O pins. The operating supply voltage ranges from 2.4 V to 3.6 V, with a typical current consumption of 11mA. It also includes an active LOW interrupt output and an internal oscillator option.

This controller is housed in a very small 16-pin TSSOP package, measuring 4.40mm in width. The operating temperature range is -40°C to 85°C. ESD protection exceeds 2000 V HBM, 200 V MM, and 1000 V CDM. Latch-up testing is performed to JEDEC Standard JESD78, exceeding 100 mA.

Applications for the SC18IS602BIPW/S8HP include converting I2C-bus to SPI and adding additional SPI bus controllers to existing systems. Its robust design and versatile interface capabilities make it suitable for various embedded system designs requiring communication between I2C and SPI peripherals.
