威尼斯游乐城appAdesto Technologies E Series SPI Flash Memory
威尼斯游乐城appAdesto Technologies E Series SPI DataFlash serial-interface sequential access Flash memory is ideally suited for a wide variety of digital voice, image, program code, and data storage applications. E Series SPI Flash also supports the RapidS serial interface for applications requiring very high speed operation. With two SRAM buffers the E Series can receive data while a page in the main memory is being reprogrammed. Interleaving between both buffers can dramatically increase a system's ability to write a continuous data stream. In addition, the SRAM buffers can be used as additional system scratch pad memory, and E2PROM emulation (bit or byte alterability) can be 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 a serial interface to sequentially access its data. The simple sequential access dramatically reduces active pin count, facilitates simplified 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 re-programmability, the E Series does not require high input voltages for programming.
