PRODUCT DESCRIPTION
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 tun-
neling 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 sup-
ply. They have to be erased prior to programming. These
devices conform to JEDEC standard pinouts for byte-wide
memories.
Featuring high-performance Byte-Program, the
GLS27SF512/010/020 provide a Byte-Program time of 20
µs. Designed, manufactured, and tested for a wide spec-
trum 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 stor-
age. 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.
Device Operation
The GLS27SF512/010/020 are a low cost flash solution
that can be used to replace existing UV-EPROM, OTP,
and mask ROM sockets. These devices are functionally
(read and program) and pin compatible with industry
standard EPROM products. In addition to EPROM func-
tionality, these devices also support electrical Erase
operation via an external programmer. They do not
require a UV source to erase, and therefore the pack-
ages do not have a window.
Read
The Read operation of the GLS27SF512/010/020 is con-
trolled by CE# and OE#. Both CE# and OE# have to be
low for the system to obtain data from the outputs. Once
the address is stable, the address access time is equal to
the delay from CE# to output (TCE). Data is available at the
output after a delay of TOE from the falling edge of OE#,
assuming that CE# pin has been low and the addresses

have been stable for at least TCE-TOE. When the CE# pin is
high, the chip is deselected and a typical standby current of
10 µA is consumed. OE# is the output control and is used
to gate data from the output pins. The data bus is in high
impedance state when either CE# or OE# is high.
Byte-Program Operation
The GLS27SF512/010/020 are programmed by using an
external programmer. The programming mode for
GLS27SF010/020 is activated by asserting 11.4-12V on
VPP pin, VDD = 4.5-5.5V, VIL on CE# pin, and VIH on OE#
pin. The programming mode for GLS27SF512 is activated
by asserting 11.4-12V on OE#/VPP pin, VDD = 4.5-5.5V,
and VIL on CE# pin. These devices are programmed byte-
by-byte with the desired data at the desired address using
a single pulse (CE# pin low for GLS27SF512 and PGM#
pin low for GLS27SF010/020) of 20 µs. Using the MTP
programming algorithm, the Byte-Programming process
continues byte-by-byte until the entire chip has been pro-
grammed.
Chip-Erase Operation
The only way to change a data from a “0” to “1” is by electri-
cal erase that changes every bit in the device to “1”. Unlike
traditional EPROMs, which use UV light to do the Chip-
Erase, the GLS27SF512/010/020 uses an electrical Chip-
Erase operation. This saves a significant amount of time
(about 30 minutes for each Erase operation). The entire
chip can be erased in a single pulse of 100 ms (CE# pin
low for GLS27SF512 and PGM# pin for GLS27SF010/
020). In order to activate the Erase mode for
GLS27SF010/020, the 11.4-12V is applied to VPP and A9
pins, VDD = 4.5-5.5V, VIL on CE# pin, and VIH on OE# pin.
In order to activate Erase mode for GLS27SF512, the 11.4-
12V is applied to OE#/VPP and A9 pins, VDD = 4.5-5.5V,
and VIL on CE# pin. All other address and data pins are
“don’t care”. The falling edge of CE# (PGM# for
GLS27SF010/020) will start the Chip-Erase operation.
Once the chip has been erased, all bytes must be verified
for FFH. Refer to Figures 13 and 14 for the flowcharts.
Product Identification Mode
The Product Identification mode identifies the devices as
the GLS27SF512, GLS27SF010 and GLS27SF020 and
manufacturer as Greenliant. This mode may be accessed
by the hardware method. To activate this mode for
GLS27SF010/020, the programming equipment must force
VH (11.4-12V) on address A9 with VPP pin at VDD (4.5-5.5V)
or VSS. To activate this mode for GLS27SF512, the pro-
gramming equipment must force VH (11.4-12V) on address
A9 with OE#/VPP pin at VIL. Two identifier bytes may then
be sequenced from the device outputs by toggling address
line A0. For details, see Tables 3 and 4 for hardware opera-
tion.
