FUNCTIONAL DESCRIPTION  
AUTO IDENTIFY MODE  
THE PROGRAMMING OF THE MX27C256  
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 MX27C256.  
When the MX27C256 is delivered, or it is erased, the  
chip has all 256K bits in the "ONE" or HIGH state.  
"ZEROs" are loaded into the MX27C256 through the  
procedure of programming.  
Forprogramming, thedatatobeprogrammedisapplied  
with 8 bits in parallel to the data pins.  
VCCmustbeappliedsimultaneouslyorbeforeVPP,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 (VH) on address line A9 of the  
device. Two identifier bytes may then be sequenced  
fromthedeviceoutputsbytogglingaddresslineA0from  
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  
MX27C256, 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 OE = VIH (Algorithm is shown in  
Figure 1). The programming is achieved by applying a  
single TTL low level 100us 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%.  
READ MODE  
TheMX27C256hastwocontrolfunctions,bothofwhich  
must be logically satisfied in order to obtain data at the  
outputs. Chip Enable (CE) is the power control and  
should be used for device selection. Output Enable  
(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  
ofOE,assumingthatCEhasbeenLOWandaddresses  
have been stable for at least tACC - tOE.  
PROGRAM INHIBIT MODE  
Programming of multiple MX27C256s 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 MX27C256 may be common. A  
TTL low-level program pulse applied to an MX27C256  
CE input with VPP = 12.5 ±0.5 V and OE HIGH will  
program that MX27C256. A high-level CE input inhibits  
the other MX27C256s from being programmed.  
STANDBY MODE  
The MX27C256 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 MX27C256 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.  
The verification should be performed with CE and OE  
at VIL, and VPP at its programming voltage.

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  
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  
usedbetweenVccandGNDforeacheightdevices. 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.
