3. GENERAL DESCRIPTION

The F49L800UA/F49L800BA is a 8 Megabit, 3V only

CMOS Flash memory device organized as 1M bytes of 8

bits or 512K words of 16bits. This device is packaged in

standard 48-pin TSOP. It is designed to be programmed

and erased both in system and can in standard EPROM

programmers.

The F49L800UA/F49L800BA features a sector erase

architecture. The device memory array is divided into one

16 Kbytes, two 8 Kbytes, one 32 Kbytes, and fifteen 64

Kbytes. Sectors can be erased individually or in groups

without affecting the data in other sectors. Multiple-sector

erase and whole chip erase capabilities provide the

flexibility to revise the data in the device.

With access times of 70 ns and 90 ns, the

F49L800UA/F49L800BA allows the operation of

high-speed microprocessors. The device has separate

The sector protect/unprotect feature disables both

program and erase operations in any combination of the

sectors of the memory. This can be achieved in-system or

via programming equipment.

chip enable

, write enable

, and output enable

controls. ESMT's memory devices reliably store memory

data even after 100,000 program and erase cycles.

A low V_CCdetector inhibits write operations on loss of

power. End of program or erase is detected by the

Ready/Busy status pin, Data Polling of DQ7, or by the

Toggle Bit I feature on DQ6. Once the program or erase

cycle has been successfully completed, the device

internally resets to the Read mode.

The F49L800UA/F49L800BA is entirely pin and

command set compatible with the JEDEC standard for 8

Megabit Flash memory devices. Commands are written to

the command register using standard microprocessor

write timings.
