DESCRIPTION
The HYNIX HY27(U/S)A(08/16)1G1M series is a family of non-volatile Flash memories that use NAND cell technology. The devices operate 3.3V and 1.8V voltage supply. The size of a Page is either 528 Bytes (512 + 16 spare) or 264 Words (256 + 8 spare) depending on whether the device has a x8 or x16 bus width.
The address lines are multiplexed with the Data Input/ Output signals on a multiplexed x8 or x16 Input/ Output bus. This interface reduces the pin count and makes it possible to migrate to other densities without changing the footprint.
Each block can be programmed and erased over 100,000 cycles. To extend the lifetime of NAND Flash devices it is strongly recommended to implement an Error Correction Code (ECC). A Write Protect pin is available to give a hard ware protection against program and erase operations.
