The GLS27SF512/010/020 are a 64K x8 / 128K x8 / 256K

x8 CMOS, Many-Time Programmable (MTP) low cost

flash, manufactured with high performance SuperFlash

technology. The split-gate cell design and thick oxide tunneling

injector attain better reliability and manufacturability

compared with alternate approaches. These MTP devices

can be electrically erased and programmed at least 1000

times using an external programmer with a 12V power supply.

They have to be erased prior to programming. These

devices conform to JEDEC standard pinouts for byte-widememories.

Featuring high-performance Byte-Program, the

GLS27SF512/010/020 provide a Byte-Program time of 20

µs. Designed, manufactured, and tested for a wide spectrum

of applications, these devices are offered with an

endurance of at least 1000 cycles. Data retention is rated at

greater than 100 years.

The GLS27SF512/010/020 are suited for applications that

require infrequent writes and low power nonvolatile storage.

These devices will improve flexibility, efficiency, and

performance while matching the low cost in nonvolatile

applications that currently use UV-EPROMs, OTPs, and

mask ROMs.

To meet surface mount and conventional through hole requirements, the GLS27SF512 are offered in 32-lead PLCC, 32-lead TSOP, and 28-pin PDIP packages. The GLS27SF010/020 are offered in 32-pin PDIP, 32-lead PLCC, and 32-lead TSOP packages. See Figures 3, 4, and 5 for pin assignments.
