AN87209 - An Overview of nvSRAM I2C I/O Specs Standardized by Cypress across I2C Modes

Last Updated: 04/26/2013
Version: **
AN87209 highlights the differences between the I2C nvSRAM I/O specifications and the NXP I2C-bus specifications. Note that these differences should not have an impact in typical I2C systems.

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 someof the I/O specifications across all modes to offer consistent I/O behavior across the modes. This standardization causes some ofits 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.
