SC18IS602B
I2C-bus to SPI bridge
Rev. 7 — 21 October 2019
Product data sheet
1. General description
The SC18IS602B is 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 SC18IS602B operates as an I2C-bus
slave-transmitter or slave-receiver and an SPI master. The SC18IS602B controls all the
SPI bus-specific sequences, protocol, and timing. The SC18IS602B has its own internal
oscillator, and it supports four SPI chip select outputs that may be configured as GPIO
when not used.
2. Features and benefits
I2C-bus slave interface operating up to 400 kHz
SPI master operating up to 1.8 Mbit/s
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
3. Applications
Converting I2C-bus to SPI
Adding additional SPI bus controllers to an existing system

[1] NXP plans to supply the /S8 device with an expected discontinuation in the 2024-2025 timeframe, but in the meantime, Failure Analysis
for /S8 devices will consist of Automated Test Equipment (ATE) and electrical overstress verification along with package and wire bond
validation only. Detailed device failure analysis will not be available; refer to CIN 201708035I.
