Summary description
Summary description
The M27W101 is a low voltage 1 Mbit EPROM offered in 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 organized as 131,072 by 8 bits.
The M27W101 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 M27W101 is offered in PDIP32, PLCC32 and TSOP32 (8 x 20 mm) packages.
In order to meet environmental requirements, ST offers the M27W101 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 M27W101 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 (tAVQV) is equal to the delay from E to output (tELQV). Data is
available at the output after a delay of tGLQV from the falling edge of G, assuming that E has
been low and the addresses have been stable for at least tAVQV-tGLQV.
2.2
Standby mode
The M27W101 has a standby mode which reduces the supply current from 15mA to 15µA
with low voltage operation VCC ≤ 3.6V, see Read Mode DC Characteristics table for details.
The M27W101 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.
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:
8/23
●
the lowest possible memory power dissipation,
●
complete assurance that output bus contention will not occur.
M27W101
Device description
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, ICC, has three segments that are of interest to
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 VCC and VSS. This should
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 VCC and VSS for every eight devices. The bulk capacitor should be located near the
power 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 M27W101 has been designed to be fully compatible with the M27C1001 and has the
same electronic signature. As a result the M27W101 can be programmed as the M27C1001
on the same programming equipment applying 12.75V on VPP and 6.25V on VCC using the
same PRESTO II algorithm. When delivered (and after each ‘1’s erasure for UV EPROM), all
bits of the M27W101 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 M27W101 is in the programming mode when VPP input is
at 12.75V, E is at VIL and P is pulsed to VIL. The data to be programmed is applied to 8 bits
in parallel to the data output pins. The levels required for the address and data inputs are
TTL. VCC is specified to be 6.25V ± 0.25V.
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 13 seconds. Programming with Presto II involves in
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 VCC much higher than 3.6V,
provides necessary margin to each programmed cell.

2.7
Program Inhibit
Programming of multiple M27W101s in parallel with different data is also easily
accomplished. Except for E, all like inputs including G of the parallel M27W101 may be
common. A TTL low level pulse applied to a M27W101's P input, with E low and VPP at
12.75V, will program that M27W101. A high level E input inhibits the other M27W101s from
being programmed.
2.8
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 VIL, P at VIH, VPP at
12.75V and VCC at 6.25V.
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 M27W101. To activate
the ES mode, the programming equipment must force 11.5V to 12.5V on address line A9 of
the M27W101, with VPP = VCC = 5V. 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 Electronic Signature mode.
10/23
M27W101
Device description
Byte 0 (A0 = VIL) represents the manufacturer code and byte 1 (A0 = VIH) the device
identifier code. For the STMicroelectronics M27W101, these two identifier bytes are given in
Table Table 3 and can be read-out on outputs Q7 to Q0.
Note that the M27W101 and M27C1001 have the same identifier byte.

Erasure operation (applies to UV EPROM)
The erasure characteristics of the M27W101 is 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. Research shows that constant exposure to room level fluorescent lighting could
erase a typical M27W101 in about 3 years, while it would take approximately 1 week to
cause erasure when exposed to direct sunlight. If the M27W101 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 M27W101 window to prevent unintentional erasure. The recommended
erasure procedure for the M27W101 is exposure to short wave ultraviolet light which has a
wavelength of 2537 Å. The integrated dose (i.e. UV intensity x exposure time) for erasure
should be a minimum of 15 W-sec/cm2. The erasure time with this dosage is approximately
15 to 20 minutes using an ultraviolet lamp with 12000 µW/cm2 power rating. The M27W101
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.
