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  
REV. 1.6, JUL. 19, 2001  
P/N: PM00694

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:
