Parallel Flash

Atmel offers parallel Flash memories in a variety of configurations and architectures to address the unique requirements of today's applications. Our first generation AT29 Series devices were developed for applications requiring updates of small portions of data throughout the memory array. The AT29 Series most notable feature is the small sector sizes ranging from 64 to 256 bytes. These small sectors create an ideal solution for both program code and data storage. The AT29 Series devices are available in densities of 256K to 4 Mbits in single voltage 5V, 3V and 2.7V options. The AT49 Series Flash devices feature Atmel's advanced NVM CMOS processing technology, single voltage operation, fast access and erase times as well as low power operation. This Flash family ranges from 512K to 128 Mbits and is available in both byte (x8) and word (x16) configurations. The AT49 Series devices were developed to meet the stringent NVM requirements for specific applications. For example, the AT49 Series Flash can be used for PC peripherals, mobile phones, networking equipment and set-top boxes. Low-density Flash products (512K to 8 Mbits) are available in 5V, 3V and 2.7V options and the High-density Flash products (16 to 128 Mbits) are available in 1.8V and 3.0V options.
