FUNCTIONAL DESCRIPTION
AUTO IDENTIFY MODE
THE PROGRAMMING OF THE MX27L2000
Theautoidentifymodeallowsthereadingoutofabinary
code from an EPROM that will identify its manufacturer
and device type. This mode is intended for use by
programming equipment for the purpose of
automatically matching the device to be programmed
with its corresponding programming algorithm. This
mode is functional in the 25°C ± 5°C ambient
temperature range that is required when programming
the MX27L2000.
When the MX27L2000 is delivered, or it is erased, the
chip has all 2M bits in the "ONE" or HIGH state.
"ZEROs" are loaded into the MX27L2000 through the
procedure of programming.
Forprogramming, thedatatobeprogrammedisapplied
with 8 bits in parallel to the data pins.
Vcc must be applied simultaneously or before Vpp, and
removed simultaneously or after Vpp. When
programming an MXIC EPROM, a 0.1uF capacitor is
required across Vpp and ground to suppress spurious
voltage transients which may damage the device.
To activate this mode, the programming equipment
must force 12.0±0.5 V on address line A9 of the device.
Two identifier bytes may then be sequenced from the
device outputs by toggling address line A0 from VIL to
VIH. All other address lines must be held at VIL during
auto identify mode.
FAST PROGRAMMING
Byte 0 ( A0 = VIL) represents the manufacturer code,
andbyte1(A0=VIH), thedeviceidentifiercode. Forthe
MX27L2000, these two identifier bytes are given in the
Mode Select Table. All identifiers for manufacturer and
devicecodeswillpossessoddparity, withtheMSB(Q7)
defined as the parity bit.
Thedeviceissetupinthefastprogrammingmodewhen
the programming voltage VPP = 12.75V is applied, with
VCC = 6.25 V and PGM = VIH (Algorithm is shown in
Figure 1). The programming is achieved by applying a
single TTL low level 100us pulse to the PGM input after
addresses and data line are stable. If the data is not
verified, an additional pulse is applied for a maximum of
25 pulses. This process is repeated while sequencing
through each address of the device. When the
programmingmodeiscompleted,thedatainalladdress
is verified at VCC = VPP = 5V ±10%.
READ MODE
The MX27L2000 has two control functions, both of
which must be logically satisfied in order to obtain data
at the outputs. Chip Enable (CE) is the power control
andshouldbeusedfordeviceselection. OutputEnable
(OE) is the output control and should be used to gate
datatotheoutputpins, independentofdeviceselection.
Assuming that addresses are stable, address access
time(tACC)isequaltothedelayfromCEtooutput(tCE).
DataisavailableattheoutputstQEafterthefallingedge
ofOE, assumingthatCEhasbeenLOWandaddresses
have been stable for at least tACC - tQE.
PROGRAM INHIBIT MODE
Programming of multiple MX27L2000s in parallel with
different data is also easily accomplished by using the
Program Inhibit Mode. Except for CE and OE, all like
inputs of the parallel MX27L2000 may be common. A
TTL low-level program pulse applied to an MX27L2000
CE input with VPP = 12.5 ±0.5 V and PGM LOW will
programthatMX27L2000. Ahigh-levelCEinputinhibits
the other MX27L2000s from being programmed.
STANDBY MODE
The MX27L2000 has a CMOS standby mode which
reduces the maximum VCC current to 100 uA. It is
placed in CMOS standby when CE is at VCC ±0.3 V.
The MX27L2000 also has a TTL-standby mode which
reduces the maximum VCC current to 1.5 mA. It is
placed in TTL-standby when CE is at VIH. When in
standby mode, the outputs are in a high-impedance
state, independent of the OE input.
PROGRAM VERIFY MODE
Verification should be performed on the programmed
bits to determine that they were correctly programmed.
TheverificationshouldbeperformedwithOEandCE,at
VIL, PGM at VIH, and VPP at its programming voltage.

MX27L2000
TWO-LINE OUTPUT CONTROL FUNCTION
SYSTEM CONSIDERATIONS
To accommodate multiple memory connections, a two-
line control function is provided to allow for:
During the switch between active and standby
conditions, transient current peaks are produced on the
rising and falling edges of Chip Enable. The magnitude
of these transient current peaks is dependent on the
outputcapacitanceloadingofthedevice. Ataminimum,
a0.1uFceramiccapacitor(highfrequency,lowinherent
inductance) should be used on each device between
Vcc and GND to minimize transient effects. In addition,
to overcome the voltage drop caused by the inductive
effects of the printed circuit board traces on EPROM
arrays, a 4.7 uF bulk electrolytic capacitor should be
used between VCC and GND for each eight devices.
The location of the capacitor should be close to where
the power supply is connected to the array.
1. Low memory power dissipation,
2. Assurance that output bus contention will not
occur.
It is recommended that CE be decoded and used as the
primary device-selecting function, while OE be made a
common connection to all devices in the array and
connectedtotheREADlinefromthesystemcontrolbus.
This assures that all deselected memory devices are in
their low-power standby mode and that the output pins
are only active when data is desired from a particular
memory device.
