Product Summary

The SIM300CZ is designed for global market. SIM300CZ is tri-band GSM/GPRS engine that works on frequencies, GSM 900 MHz, DCS 1800 MHz and PCS1900 MHz. The SIM300CZ features GPRS multi-slot class 10 /Class 8 capability and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. SIM300CZ also provides GPRS multi-slot class 8 and the default is class 10.

Parametrics

SIM300CZ absolute maximum ratings: (1)Dimensions: 33mmx33mmx3mm ; (2)Weight: 7.8g ; (3)Supply voltage range: 3.4V to 4.5V ; (4)Normal operation temperature: -20 ℃ to +55 ℃ ; (5)Restricted operation temperature: -30 ℃ to -20 ℃ and +55 ℃ to +80 ℃ ; (6)Storage temperature: -40 ℃ to +85 ℃.

Features

SIM300CZ features: (1)9 GND PINS and 2 VBAT pins; (2)1 pin is programmable as General Purpose I/O. This gives you the flexibility to develop customized applications; (3)Serial port and Debug port can help you easily develop your applications. But they can not work at the same time; (4)Two audio channels include two microphone inputs and two speaker outputs. This can be easily configured by AT command.
