M27C4001 Summary description
1 Summary description
The M27C4001 is a 4 Mbit EPROM offered in the two ranges UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited for microprocessor systems requiring
large programs and is organised as 524,288 by 8 bits.
The FDIP32W (window ceramic frit-seal package) has a transparent lid which allows the
user to expose the chip to ultra viol et light to er ase the bit pattern. A ne w pattern can then be
written to the device by following the programming procedure.
For applications where the content is programmed only one time and erasure is not
required, the M27C4001 is off er ed in PDIP32 , PLCC32 an d TSOP32 ( 8 x 20 mm) p ac kages .
In order to meet environmental requirements, ST offers the M27C4001 in ECOPACK®
packages.
ECOPACK packages are Lead-free. The category of second Level Interconnect is marked
on the package and on the inner box label, in compliance with JEDEC Standard JESD97.
The maximum ratings related to soldering conditions are also marked on the inner box label.
ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com.

Device operation M27C4001
2 Device operation
The operating modes of the M27C4001 are listed in the Operating Modes table. A single
power supply is required in t he read mod e. All inputs are TTL levels except for V
on A9 for Electronic Signature.

obtain data at the outputs. Chip Enable (E

2.2 Standby Mode
The M27C4001 has a standby mode which reduces the supply curr ent from 30mA t o 100µA.
The M27C4001 is placed in the standby mode by applying a CMOS high signal to the E
input. When in the standby mo de, the ou tputs are in a high impedance stat e, indepe ndent of

2.3 Two Line Output Control
Because EPROMs are usually used in larger memory arrays, this product features a 2 line
control function which accommodates the use of multiple memory connection. The two line
control function allows:
a) the lowest possible memory power dissipation,
b) complete assurance that output bus contention will not occur.
For the most efficient use of these two control lines, E

2.4 System Considerations
The power switching characteristics of Advanced CMOS EPROMs require careful
decoupling of the devices. The supply current, I
, has three segments that are of interest to
CC
the system designer: the standby current le v el, the activ e cur rent le v el, a nd tran sient current
peaks that are produced by the f alling an d rising edges of E
. The magnitude of the tra nsient
current peaks is dependent on the capacitive and inductive loading of the device at the
output. The associated transient voltage peaks can be suppressed by complying with the
two line output control and by properly selected decoupling capacitors. It is recommended
that a 0.1µF ceramic capacitor be used on every de vice be tween V
and VSS. This should
CC
be a high frequency capacitor of low inherent inductance and should be placed as close to
the device as possible. In addition, a 4.7µF bulk electrolytic capacitor should be used
between V
and VSS for ev ery eight devices . The bulk capacitor sh ould be located near the
CC
power supply connection point. The purpose of the bulk capacitor is to o v ercome the v oltage
drop caused by the inductive effects of PCB traces.
2.5 Programming
When delivered (and after each erasur e f or UV EPR OM), all bits of t he M27C4001 are in the
'1' state. Data is introduced by selectively programming '0's into the desired bit locations.
Although only '0's will be programmed, both '1's and '0's can be present in the data word.
The only way to change a ' 0' to a '1' is by die exposure to ultraviolet light (UV EPROM). The
M27C4001 is in the programming mode when V

2.6 PRESTO II Programming Algorithm
PRESTO II Programming Algorithm allows the whole array to be programmed with a
guaranteed margin, in a typical time of 52.5 seconds. Programming with PRESTO II
consists of applying a sequence of 100µs program pulses to each byte until a correct verify
occurs (see Figure 5). During programming and verify oper ation, a MARGIN MODE circuit is
automatically activated in order to guarantee that each cell is programmed with enough
margin. No overprogram pulse is applied since the verify in MARGIN MODE provides the
necessary margin to each programmed cell.

Programming of multiple M27C4001s in parallel with different data is also easily
accomplished. Except for E

2.9 Electronic Signature
The Electronic Signature (ES) mode allows the reading out of a binary code from an
EPROM that will identify its manufacturer and type. This mode is intended for use by
programming equipment to automatically match the device to be programmed with its
corresponding programming algorithm. The ES mode is functional in the 25°C ± 5°C
ambient temperature range that is required when programming the M27C4001. To activate
the ES mode, the progr amm ing e qui pme nt must force 11.5V to 12.5V on address line A9 of
the M27C4001 with V
device outputs by toggling address line A0 from V
held at V
during Electronic Signature mode. Byte 0 (A0 = VIL) represents the manufacturer

2.10 Erasure operation (applies to UV EPROM)
The erasure characteristics of the M27 C4001 are such that erasure begins when the cells
are exposed to light with w a velen gths shorter than approximately 400 0 Å. It should be noted
that sunlight and some type of fluorescent lamps have wavelengths in the 3000-4000 Å
range. Data shows that constant exposure to room level fluorescent lighting could erase a
typical M27C4001 in about 3 years, while it would take approximately 1 week to cause
erasure when exposed t o direct sunlight. If the M27C4001 is to be e xposed to these types of
lighting conditions for extended periods of time, it is suggested that opaque labels be put
over the M27C4001 window to prevent unintentional erasure. The recommended erasure
procedure for the M27C4001 is exposure to short wave ultraviolet light which has
wavelength of 2537 Å. The integrated dose (i.e. UV intensity x exposure time) for erasure
should be a minimum of 15 W-sec/cm
15 to 20 minutes using an ultrav iolet lamp with 1200 0 µW/cm
should be placed within 2.5 cm (1 inch) of the lamp tubes during the erasure. Some lamps
have a filter on their tubes which should be removed before erasure.
