AN4017 - Understanding Temperature Specifications: An Introduction

Last Updated: 
Apr 28, 2017

AN4017 gives a basic understanding of the temperature specifications found in Cypress's product datasheets. There are many factors that affect the thermal operation of a device. This application note also gives you an understanding of the thermal parameters and temperature specifications of the device. 

This document describes the various thermal parameters namely Ambient Temperature (Ta), Case Temperature (Tc), Junction Temperature(Tj), Thermal Resistance, Power Dissipation etc.

Details on calculating Junction Temperature are provided in this application note.

Clicking on the link below provides a tool which enables calculation of the I/O Switching Current (Iddq) for desired frequency, Total Power Consumption and Junction Temperature for Sync SRAMs

Please refer to the respective product datasheets to get the Vdd voltage and Idd current used in the formula.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you. 

Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
