W631GU8KB-12 TR

Introduction

W631GU8KB-12 TR is a module of non-volatile memory of NOR-type which provided by Winbond. It can offer Multiple I/O combination and high system performance when providing reliable data storage and program code execution capabilities. W631GU8KB-12 TR is adaptable of working voltage from 3.0V to 3.6V and very suitable for the low power or harsh environment system.

Application Field

W631GU8KB-12 TR is mainly used for system code storage or data read/write storage in handheld battery powered systems such as PDA, smart card and embedded applications, especially for the XScale Based CPU system. It acts as the main booting source to realize power up any system quickly. It is also applicable in universal applications, providing high speed data transfer rate, 8/16/24 bit multiple I/O selection, supported direct write and read operation.

Working Principle

W631GU8KB-12 TR is capable to work in a wide range of temperature and voltage, so as to save min power consumption when support reliable data storage and program code execution capacity. It mainly contains a NOR Flash memory and a serial communication controller and associated firmware.

When it comes to the working principle, serial NOR is based on the traditional NOR Flash command set and fast I/O command set. In case of NOR Flash command set, there are common commands to read, program and erase. That is, when a memory device is needed, it loads the required program into the NOR Flash array by the command sequence. Since the manufacturer coded commands are clear, the operation of memory device issimple and understandable.

Another way is to code the command of serial NOR Flash with high speed command set. This kind of command set has fewer commands, but it can achieve faster data transfer rate up to 10 times the speed of traditional command set. The lower latency and fast command rate is provided by the internal command parser and execution engine.

Conclusion

W631GU8KB-12 TR is a type of non-volatile memory of NOR-type which is provided by Winbond. It can offer multiple I/O combination, high system performance and low power consumption when providing reliable data storage and program code execution capabilities. It is mainly used for system code storage or data read/write storage in handheld battery powered systems such as PDA, smart card and embedded applications. The working principle of W631GU8KB-12 TR also illustrates that it is based on NOR Flash command set and fast I/O command set which has fewer commands but faster data transfer rate up to 10 times the speed.
