GENERAL DESCRIPTION
The F25L004A is a 4Megablt, 3V only CMOS Serial Flash
memory device organized as 512K bytes of 8 bits. This device is
packaged in 8-lead SOIC 200mil. 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.
