Reduce system costs and improve system security with SLC NAND Flash memory range

Cypress Semiconductor has introduced a Single-Level Cell (SLC) NAND Flash range for high-security applications. Designers of high-security applications have been using a NOR Flash memory with block protection for boot code storage and a commodity SLC NAND Flash memory for system firmware and application storage.

The Cypress SecureNAND range of devices is said to reduce system costs and improve system security by providing a single nonvolatile memory with integrated block protection features for set-top boxes, point-of-sale systems, wearables and other high-security applications.

The Cypress SecureNAND family includes 1, 2 and 4Gbyte devices, all of which offer the ability to configure the device with nonvolatile block protection to store protected boot code, system firmware and applications. These products are claimed to provide 100,000 program/erase cycles to give more than five years of system life. The devices have an operating voltage range of 2.7 to 3.6V and operate across the industrial temperature range of -40 to 85°C.
