AT45DB161D-SU

Product Summary

The AT45DB161D-SU is one member of the AT45DB161D series. The AT45DB161D is a 2.5-volt or 2.7-volt, serial-interface sequential access Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. The AT45DB161D supports Rapid serial interface for applications requiring very high speed operations. RapidS serial interface is SPI compatible for frequencies up to 66 MHz. Its 17,301,504 bits of memory are organized as 4,096 pages of 512 bytes or 528 bytes each. In addition to the main memory, the AT45DB161D also contains two SRAM buffers of 512/528 bytes each.

Parametrics

Absolute maximum ratings of the AT45DB161D-SU can be summarized as:(1)temperature under bias:-55 to 125℃; (2)storage temperature:-65 to 150℃;(3)all input voltages (including NC pins)with respect to ground:-0.6 to 6.25V; (4)all output voltages with respect to ground:-0.6 to Vcc+0.6V.Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.The Sector Protection Register can be reprogrammed while the sector protection enabled or disabled. Being able to reprogram the Sector Protection Register with the sector protection enabled allows the user to temporarily disable the sector protection to an individual sector rather than disabling sector protection completely.
