GENERAL DESCRIPTION

The F25L004A is a 4 Megabit 3V only CMOS Serial Flash memory device. ESMT’s memory devices reliably store memory data even after 100,000 program and erase cycles.

The F25L004A features a sector erase architecture. The device memory array is divided into 128 uniform sectors with 4K byte each ; 8 uniform blocks with 64K byte each. Sectors can be erased individually without affecting the data in other sectors.

Blocks can be erased individually without affecting the data in other blocks. Whole chip erase capabilities provide the flexibility to revise the data in the device.

The sector protect/unprotect feature disables both program and erase operations in any combination of the sectors of the memory.
