DESCRIPTION
The M27W202 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 131,072 by
16 bits.
The M27W202 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 FDIP40W (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 PDIP40, PLCC44 and
TSOP40 (10 x 14 mm) packages.

DEVICE OPERATION
The operating modes of the M27W202 are listed in
the Operating Modes table. A single power supply
is required in the read mode. All inputs are TTL
levels except for VPP and 12V on A9 for Electronic
Signature.
Read Mode
The M27W202 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
4/15
(tAVQV) is equal to the delay from E to output
(tELQV). Data is available at the output after a delay
of tOE from the falling edge of G, assuming that E
has been low and the addresses have been stable
for at least tAVQV-t GLQV.
Standby Mode
The M27W202 has a standby mode which reduces the supply current from 15mA to 15µA with low
voltage operation VCC â 3.6V, see Read Mode DC
Characteristics table for details.
The M27W202 is placed in the standby mode by
applying a TTL high signal to the E input. When in
the standby mode, the outputs are in a high impedance state, independent of the G input.

Two Line Output Control
Because OTP 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 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.
System Considerations
The power switching characteristics of Advanced
CMOS EPROMs require careful decoupling of the
devices. The supply current, I CC, 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
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.

Programming
When delivered, all bits of the M27W202 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
M27W202 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 16 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.

PRESTO II Programming Algorithm
PRESTO II Programming Algorithm allows programming of the whole array with a guaranteed
margin, in a typical time of 13 seconds. Programming with PRESTO II consists of applying a sequence of 100 µs program pulses to each word
until a correct verify occurs (see Figure 7). 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 CC much
higher than 3.6V, provides necessary margin to
each programmed cell.
Program Inhibit
Programming of multiple M27W202s in parallel
with different data is also easily accomplished. Except for E, all like inputs including G of the parallel
M27W202 may be common. A TTL low level pulse
applied to a M27W202’s P input, with E low and
VPP at 12.75V, will program that M27W202. A high
level E input inhibits the other M27W202s 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 VIL, P at VIH, VPP at 12.75V and VCC at
6.25V.
M27W202
On-Board Programming
The M27W202 can be directly programmed in the
application circuit. See the relevant Application
Note AN620.
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 M27W202. To activate the ES
mode, the programming equipment must force
11.5V to 12.5V on address line A9 of the
M27W202 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 V IL during
Electronic Signature mode. Byte 0 (A0 = VIL) represents the manufacturer code and byte 1
(A0 = VIH) the device identifier code. For the
STMicroelectronics M27W202, these two identifier
bytes are given in Table 4 and can be read-out on
outputs Q7 to Q0.
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 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 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.
