The buffers allow receiving of data while a page in the main memory is being reprogrammed. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a serial interface to sequentially access its data. The simple serial interface facilitates hardware 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 applications where high density, low pin count, low voltage, and low power are essential. Typical applications for the DataFlash are digital voice storage, image storage, and data storage. The device operates at clock frequencies up to 15 MHz with a typical active read current consumption of 15 mA. To allow for simple in-system reprogrammability, the AT45D161 does not require high input voltages for programming. The device operates from a single power supply, 4.5V to 5.5V, for both the program and read operations. The AT45D161 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 . All programming cycles are self-timed, and no separate erase cycle is required before programming.
