AN87209 - OVERVIEW OF NVSRAM I2C I/O SPECS STANDARDIZED BY CYPRESS ACROSS I2C MODES

Introduction

The I2C nvSRAM offers all four standard I2C-bus modes (Standard-mode - 100KHz, Fast-mode - 400 KHz, Fast-mode plus - 1 MHz, and High-speed mode - 3.4 MHz) through a single solution. As a result, Cypress has standardized some of the I/O specifications across all modes to offer consistent I/O behavior across the modes. This standardization causes some of its I/O specifications slightly differ than NXP I2C standard. This application note highlights the I2C nvSRAM spec differences from the standard NXP I2C-bus specification.
