简  介:Features Single 2.5V - 3.6V or 2.7V - 3.6V Supply Serial Peripheral Interface (SPI) Compatible 20 MHz Max Clock Frequency Page Program Operation – Single Cycle Reprogram (Erase and Program) – 2048 Pages (264 Bytes/Page) Main Memory Supports Page and Block Erase Operations Two 264-byte SRAM Data Buffers – Allows Receiving of Data while Reprogramming the Flash Memory Array Continuous Read Capability through Entire Array – Ideal for Code Shadowing Applications Low Power Dissipation – 4 mA Active Read Current Typical – 2 A CMOS Standby Current Typical Hardware Data Protection Feature 5.0V-tolerant Inputs: SI, SCK, CS, RESET, and WP Pins Commercial and Industrial Temperature Ranges Green (Pb/Halide-free/RoHS Compliant) Package Options 4-megabit 2.5-volt or 2.7-volt DataFlash AT45DB041B 1. Description The AT45DB041B is an SPI compatible serial interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. Its 4,325,376 bits of memory are organized as 2048 pages of 264 bytes each. In addition to the main memory, the AT45DB041B also contains two SRAM data buffers of 264 bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed, as well as reading or writing a continuous data stream. EEPROM emulation (bit or byte alterability) is easily handled with a self-contained three step Read-ModifyWrite operation. Unlike conventional Flash memories that are accessed rand……
