AT45DB321D-MU

The AT45DB321D-MU is one member of the AT45DB321D family which is designed as the 2.7-volt, serial-interface sequential access Flash memory device that supports RapidS serial interface for applications requiring very high speed operations. This device also contains two SRAM buffers of 512/528 bytes each, and is enabled through the chip select pin (CS) and accessed via a three-wire interface consisting of the Serial Input (SI), Serial Output (SO), and the Serial Clock (SCK).

Features of the AT45DB321D-MU are:(1)Single 2.7V to 3.6V Supply;(2)Green (Pb/Halide-free/RoHS Compliant) Packaging Options;(3)Industrial Temperature Range;(4)Data Retention 20 Years;(5)100,000 Program/Erase Cycles Per Page Minimum;(6)JEDEC Standard Manufacturer and Device ID Read;(7)Continuous Read Capability through Entire Array - Ideal for Code Shadowing Applications;(8)Two SRAM Data Buffers (512/528 Bytes) - Allows Receiving of Data while Reprogramming the Flash Array.

The absolute maximum ratings of the AT45DB321D-MU can be summarized as:(1)Temperature under Bias: -55°C to +125°C;(2)Storage Temperature:-65°C to +150°C;(3)All Input Voltages (including NC Pins) with Respect to Ground: -0.6V to +6.25V;(4)All Output Voltages with Respect to Ground: -0.6V to VCC + 0.6V.
