Summary description
The M27W201 is a low voltage 2 Mbit EPROM offered in the two range UV (ultra violet
erase) and OTP (one time programmable). It is ideally suited for microprocessor systems
requiring large data or program storage and is organised as 262,144 by 8 bits.
The M27W201 operates in the read mode with a supply voltage as low as 2.7V at –40 to
85°C temperature range. The decrease in operating power allows either a reduction of the
size of the battery or an increase in the time between battery recharges.
The FDIP32W (window ceramic frit-seal package) has a transparent lid which allows the
user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be
written to the device by following the programming procedure.
For application where the content is programmed only one time and erasure is not required,
the M27W201 is offered in PDIP32, PLCC32 and TSOP32 (8 x 20mm and 8 x 14mm)
packages.
In order to meet environmental requirements, ST offers the M27W201 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.

2.1
Read mode
The M27W201 has two control functions, both of which must be logically active in order to
obtain data at the outputs. Chip Enable (E) is the power control and should be used for
device selection. Output Enable (G) is the output control and should be used to gate data to
the output pins, independent of device selection. Assuming that the addresses are stable,
the address access time (t
) is equal to the delay from E to output (t
). Data is
AVQV
ELQV
available at the output after a delay of t
from the falling edge of G, assuming that E has
GLQV
been low and the addresses have been stable for at least t
-t
.
AVQV GLQV
2.2
Standby mode
The M27W201 has a standby mode which reduces the supply current from 15mA to 15µA
with low voltage operation V ≤ 3.6V, see Read Mode DC Characteristics table for
CC
details.The M27W201 is placed in the standby mode by applying a CMOS high signal to the
E input. When in the standby mode, the outputs are in a high impedance state, independent
of the G input.

Device Description
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:
■
■
the lowest possible memory power dissipation,
complete assurance that output bus contention will not occur.
For the most efficient use of these two control lines, E should be decoded and used as the
primary device selecting function, while G should be made a common connection to all
devices in the array and connected to the READ line from the system control bus. This
ensures that all deselected memory devices are in their low power standby mode and that
the output pins are only active when data is required from a particular memory device.
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 level, the active current level, and transient current
peaks that are produced by the falling and rising edges of E. The magnitude of the transient
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 device between V and V . This should be a
CC
SS
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 V for every eight devices. The bulk capacitor should be located near the power
CC
SS
supply connection point. The purpose of the bulk capacitor is to overcome the voltage drop
caused by the inductive effects of PCB traces.
2.5
Programming
The M27W201 has been designed to be fully compatible with the M27C2001 and has the
same electronic signature. As a result the M27W201 can be programmed as the M27C2001
on the same programming equipment applying 12.75V on V and 6.25V on V by the use
PP
CC
of the same PRESTO II algorithm.
When delivered (and after each ‘1’s erasure for UV EPROM), all bits of the M27W201 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
M27W201 is in the programming mode when V input is at 12.75V, E is at V and P is
PP
IL
pulsed to V . The data to be programmed is applied to 8 bits in parallel to the data output
IL
pins. The levels required for the address and data inputs are TTL. V is specified to be
CC
6.25V ± 0.25V.

Presto II programming algorithm
Presto II Programming Algorithm allows the whole array to be programmed with a
guaranteed margin, in a typical time of 26.5 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 operation, 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 at V much higher than 3.6V,
CC
provides the necessary margin to each programmed cell.

Program Inhibit
Programming of multiple M27W201s in parallel with different data is also easily
accomplished. Except for E, all like inputs including G of the parallel M27W201 may be
common. A TTL low level pulse applied to a M27W201's P input, with E low and V at
12.75V, will program that M27W201. A high level E input inhibits the other M27W201s from
being programmed.

Program Verify
A verify (read) should be performed on the programmed bits to determine that they were
correctly programmed. The verify is accomplished with E and G at V , P at V , V at

Device Description

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 M27W201. To activate
the ES mode, the programming equipment must force 11.5V to 12.5V on address line A9 of
the M27W201 with V = V = 5V. Two identifier bytes may then be sequenced from the
PP
CC
device outputs by toggling address line A0 from V to V . All other address lines must be
IL
IH
held at V during Electronic Signature mode. Byte 0 (A0 = V ) repres ents the manufacturer
IL
IL
code and byte 1 (A0 = V ) the device identifier code. For the STMicroelectronics
IH
M27W201, these two identifier bytes are given in Table 3 and can be read-out on outputs Q7
to Q0. Note that the M27W201 and M27C2001 have the same identifier byte.

Erasure operation (applies to UV EPROM)
The erasure characteristics of the M27W201 are such that erasure begins when the cells
are exposed to light with wavelengths shorter than approximately 4000 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 M27W201 in about 3 years, while it would take approximately 1 week to cause
erasure when exposed to direct sunlight. If the M27W201 is to be exposed to these types of
lighting conditions for extended periods of time, it is suggested that opaque labels be put
over the M27W201 window to prevent unintentional erasure. The recommended erasure
procedure for the M27W201 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
2
minimum of 15 W-sec/cm . The erasure time with this dosage is approximately 15 to 20
2
minutes using an ultraviolet lamp with 12000 µW/cm power rating. The M27W201 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.
