AT45DB161D-SU

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 RapidS 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.

Features of the AT45DB161D-SU are:(1)512 bytes per page; (2)528 bytes per page; (3)page size can be factory pre-configured for 512 bytes; (4)intelligent programming operation; (5)4,096 pages (512/528 bytes/page) main memory; (6)allows receiving of data while reprogramming the flash array; (7)continuous read capability through entire array; (8)ideal for code shadowing applications; (9)JEDEC standard manufacturer and device ID read; (10)100,000 program/erase cycles per page minimum; (11)data retention20 years; (12)industrial temperature range; (13)green (Pb/halide-free/RoHS compliant) packaging options.

The 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 AT45DB161D-SU 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.
