PROGRAM INHIBIT MODE
CE
Programming of multiple MX27C4000As 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 MX27C4000A may be common. A
TTL low-level program pulse applied to an
MX27C4000A CE input with VPP = 12.5±0.5 V and CE
LOW will program that MX27C4000A. A high-level CE
input inhibits the other MX27C4000As from being
programmed.

PROGRAM VERIFY MODE
Verification should be performed on the programmed
bits to determine that they were correctly programmed.
The verification should be performed with OE and CE at
VIL, and VPP at its programming voltage.
FUNCTIONAL DESCRIPTION
THE PROGRAMMING OF THE MX27C4000A
AUTO IDENTIFY MODE
When the MX27C4000A is delivered, or it is erased,
the chip has all 4M bits in the "ONE" or HIGH state.
"ZEROs" are loaded into the MX27C4000A through the
procedure of programming.
Theautoidentifymodeallowsthereadingoutofabinary
code from an OTP ROM that will identify its
manufactureranddevicetype. Thismodeisintendedfor
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 MX27C4000A.
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 OTP ROM, a 01uF 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±0.5VonaddresslineA9ofthedevice.
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
Thedeviceissetupinthefastprogrammingmodewhen
the programming voltage VPP = 12.75V is applied, with
VCC = 6.25 V and OE = VIH (Algorithm is shown in
Figure 1). The programming is achieved by applying a
single TTL low level 10us pulse to the CE 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%.
Byte 0 ( A0 = VIL) represents the manufacturer code,
andbyte1(A0=VIH), thedeviceidentifiercode. Forthe
MX27C4000A,thesetwoidentifierbytesaregiveninthe
Mode Select Table. All identifiers for manufacturer and
devicecodeswillpossessoddparity, withtheMSB(Q7)
defined as the parity bit.
READ MODE
The MX27C4000A 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).
DataisavailableattheoutputstOEafterthefallingedge
of OE's, assuming that CE has been LOW and
addresses have been stable for at least tACC - tOE.
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.
STANDBY MODE
The MX27C4000A 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.
TheMX27C4000AalsohasaTTL-standbymodewhich
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.
SYSTEM CONSIDERATIONS
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
VCCandGNDtominimizetransienteffects. Inaddition,
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.
TWO-LINE OUTPUT CONTROL FUNCTION
To accommodate multiple memory connections, a two-
line control function is provided to allow for:
1. Low memory power dissipation,
