2 / 32 page 2 AT45DB011B 1984H–DFLSH–10/04 layout, increases system reliability, minimizes switching noise, and reduces package size and active pin count. The device is optimized for use in many commercial and industrial applica- tions where high density, low pin count, low voltage, and low power are essential. The device operates at clock frequencies up to 20 MHz with a typical active read current consumption of 4mA. To allow for simple in-system reprogrammability, the AT45DB011B does not require high input voltages for programming. The device operates from a single power supply, 2.7V to 3.6V, for both the program and read operations. The AT45DB011B is enabled through the chip select pin (CS) and accessed via a three-wire interface consisting of the Serial Input (SI), Serial Out- put (SO), and the Serial Clock (SCK). All programming cycles are self-timed, and no separate erase cycle is required before programming. When the device is shipped from Atmel, the most significant page of the memory array may not be erased. In other words, the contents of the last page may not be filled with FFH. Block Diagram Memory Array To provide optimal flexibility, the memory array of the AT45DB011B is divided into three levels of granularity comprising of sectors, blocks, and pages. The Memory Architecture Diagram illustrates the breakdown of each level and details the number of pages per sector and block. All program operations to the DataFlash occur on a page by page basis; however, the optional erase operations can be performed at the block or page level.
