1. Introduction

This document describes electrical specifications, mechanical information, interfaces application and
manufacturing information about SIM5800 module. With the help of this document and other application notes or
user guide, users can understand SIM5800 well and develop various products quickly.

2. Overview

SIM5800 is a multi-mode and multi-band wireless smart module, which is based on MTK MT8321 platform. It
includes baseband, memory, RF front end and required circuitry to support rich multimedia features, global
location-based service, wireless connectivity, and air interface standards including WCDMA, GSM/GPRS/EDGE.
With higher integration to reduce PCB surface area, time-to-market, and BOM costs, SIM5800 will help drive
wireless products adoption in more industry around the world.
There are 210 pins on SIM5800 which provide most application interfaces for users' board.
