A new line of 5V parallel NOR Flash memory products in boot and uniform sectored architectures has been introduced by Alliance Memory. Available in densities from 1M to 16M, the devices offer access times of 55ns to enable fast, low-latency read speeds, allowing for both direct code execution and data storage in a single memory product.
Offering reliable, long-term performance for embedded systems, the NOR Flash devices released today feature a minimum of 100,000 program/erase cycles per sector and offer 20-year data retention at +125°C.
With their fast boot times, the solutions are ideal for high-performance applications such as digital still cameras (DSC and DSLR), in addition to process-intensive networking routers and switches, home gateways, set-top boxes (STBs), automotive infotainment systems, industrial robotics, and medical electronics.
The devices' flexible sector architectures allow any combination of sectors to be erased and reprogrammed without affecting the content of other sectors — ensured by a hardware protection feature that prevents inadvertent program or erase operations.
An Embedded Program algorithm automatically writes and verifies bytes at specified addresses, while an Embedded Erase algorithm automatically erases and verifies the entire chip or designated sectors.
The products operate over an industrial temperature range of -40°C to +85°C and offer 20mA typical active read currents and 30mA typical program/erase currents. In standby mode, power consumption is reduced to as low as 1μA.
Uniform sector devices are available in the 32-pin PLCC package, while boot devices — in top or bottom block configurations — are available in the 48-pin TSOP I package.
Each part can also be programmed in standard EPROM programmers. All devices are lead (Pb)-free and RoHS 2.0 compliant.
