AT45DB041B-SU

The AT45DB041B-SU is designed as one kind of  SPI compatible serial interface Flash memory device that can be used in a wide variety of digital voice-, image-, program code- and data-storage applications. And this device is enabled through the chip select pin (CS) and accessed via a threewire interface consisting of the Serial Input (SI), Serial Output (SO), and the Serial Clock (SCK).

Features of the AT45DB041B-SU are:(1)Single 2.5V - 3.6V or 2.7V - 3.6V Supply; (2)Serial Peripheral Interface (SPI) Compatible; (3)20 MHz Max Clock Frequency; (4)Page Program Operation; (5)Single Cycle Reprogram (Erase and Program); (6)2048 Pages (264 Bytes/Page) Main Memory; (7)Supports Page and Block Erase Operations; (8)Two 264-byte SRAM Data Buffers ?Allows Receiving of Data while Reprogramming the Flash Memory Array; (9)Continuous Read Capability through Entire Array; (10)Ideal for Code Shadowing Applications; (11)Low Power Dissipation: 4 mA Active Read Current Typical and 2 uA CMOS Standby Current Typical; (12)Hardware Data Protection Feature; (13)5.0V-tolerant Inputs: SI, SCK, CS, RESET, and WP Pins; (14)Commercial and Industrial Temperature Ranges; (15)Green (Pb/Halide-free/RoHS Compliant) Package Options.

The absolute maximum ratings of the AT45DB041B-SU 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.
