1. Description

The AT45DB321C is an SPI compatible, serial-interface Flash memory ideally suited

for a wide variety of digital voice-, image-, program code- and data-

storage applications. The AT45DB321C supports a 4-wire serial interface known as

RapidS for applications requiring very high speed operations.

Its 34,603,008 bits of memory are organized as 8192 pages of 528 bytes each. In

addition to the 33-megabit main memory, the AT45DB321C also contains two SRAM

buffers of 528 bytes each.

The buffers allow the receiving of data while a page in the main page 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 mul-

tiple address lines and a parallel interface, the DataFlash uses a RapidS serial

interface to sequentially access its data. The simple sequential access dramatically

reduces active pin count, facilitates hardware layout, increases system reliability, min-

imizes 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. The device operates at clock frequencies up to

40 MHz with a typical active read current consumption of 10 mA.
