Page 1 Page 2 megabit 2. The dual-interface allows a dedicated serial interface to be connected to a DSP and a dedicated 8-bit interface to be connected to a microcontroller or vice versa. However, the use of either interface is purely optional. Its 69,, bits of memory are organized as 8, pages of 1, bytes binary page size or 1, bytes standard DataFlash page size each. The buffers allow receiving of data while a page in the main Memory is being reprogrammed, as well as writing a continuous data stream.
EEPROM emulation bit or byte alterability is easily handled with a self-contained three step read-modify- write operation.
Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses either a RapidS serial interface or a 8-bit Rapid8 interface to sequentially access its data. The simple sequential access dramatically reduces active pin count, facilitates hardware layout, increases system reliability, minimizes switching noise, and reduces package size.
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. To allow for simple in-system reprogrammability, the AT45DBD does not require high input voltages for programming.
The device operates from a single power supply, 2. All programming and erase cycles are self-timed.
