Datasheet
Datasheet Summary
Powered by GS/AI

The AT45DB041B-TC is a 4-megabit serial Flash memory device that operates with a supply voltage of 2.5V to 3.6V. It features a Serial Peripheral Interface (SPI) compatible design, allowing for a maximum clock frequency of 20 MHz. The memory is organized into 2048 pages of 264 bytes each, and it includes two SRAM data buffers of the same size, enabling data reception while reprogramming the Flash memory. This device supports both page and block erase operations and offers continuous read capability, making it suitable for applications such as code shadowing. It has a low active read current of 4 mA and a standby current of 2 ¬µA, contributing to its low power dissipation. The AT45DB041B-TC also includes hardware data protection features and is available in various package options, including a 28-lead Thin Small Outline Package (TSOP). It is compliant with RoHS standards, ensuring it is environmentally friendly. The device is suitable for both commercial and industrial applications, with operating temperature ranges of 0¬8C to 70¬8C and -40¬8C to 85¬8C, respectively.
