1. Introduction

This document describes SIM800C hardware interface in great detail. The document can help customer to

quickly understand SIM800C interface specifications, electrical and mechanical details. With the help of this

document and other SIM800C application notes, customer guide, customers can use SIM800C to design various

applications quickly.

2. SIM800C Overview

SIM800C is a quad-band GSM/GPRS module that works on frequencies GSM850MHz, EGSM900MHz,

DCS1800MHz and PCS1900MHz. SIM800C features GPRS multi-slot class10/class12 (optional) and supports

the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.

With a tiny configuration of 17.6*15.7*2.3mm, SIM800C can meet almost all the space requirements in

customers’ applications, such as smart phone, PDA and other mobile devices.

SIM800C is a SMT package with 42 pads, and provides all hardware interfaces between the module and

customers’ boards.
