Datasheet
Datasheet Summary
Powered by GS/AI

The AT45DB081B-RI is a serial interface Flash memory device from Quarktwin Technology Ltd. designed for a variety of digital storage applications. It operates on a supply voltage of 2.5V to 3.6V and supports a maximum clock frequency of 20 MHz. The memory capacity is 8,650,752 bits, organized into 4096 pages of 264 bytes each. It features two SRAM data buffers of 264 bytes, allowing for data reception while reprogramming the main memory. This device supports both page and block erase operations and offers continuous read capability, making it suitable for code shadowing applications. The typical active read current is 4 mA, with a low standby current of 2 ¬µA, contributing to its low power dissipation. The AT45DB081B-RI is also equipped with hardware data protection features and is compatible with the AT45DB081 and AT45DB081A models. It is available in various package types, including a 28-lead SOIC package, and is rated for industrial temperature ranges from -40¬8C to 85¬8C.
