DESCRIPTION
The M27C801 is an 8 Mbit EPROM offered in the
two ranges UV (ultra violet erase) and OTP (one
time programmable). It is ideally suited for applications where fast turn-around and pattern experimentation are important requirements and is
organized as 1,048,576 by 8 bits.
The FDIP32W (window ceramic frit-seal package)
has 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 applications where the content is programmed
only one time and erasure is not required, the
M27C801 is offered in PDIP32, PLCC32 and
TSOP32 (8 x 20 mm) packages.

DEVICE OPERATION
The operating modes of the M27C801 are listed in
the Operating Modes table. A single power supply
is required in the read mode. All inputs are TTL
levels except for GVPP and 12V on A9 for Electronic Signature and Margin Mode Set or Reset.
Read Mode
The M27C801 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 ad-
4/16
dresses 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 t GLQV from the falling edge of G, assuming that
E has been low and the addresses have been stable for at least tAVQV-tGLQV.
Standby Mode
The M27C801 has a standby mode which reduces
the supply current from 35mA to 100µA.
The M27C801 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 GVPP input.

Two Line Output Control
Because EPROMs are usually used in larger
memory arrays, the 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
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
6/16
output control and by properly selected decoupling
capacitors. It is recommended that a 0.1µF ceramic capacitor be used on every device between V CC
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 (and after each erasure for UV
EPROM), all bits of the M27C801 are in the ’1’
state. Data is introduced by selectively programming ’0’s into the desired bit locations. Although
only ’0’ 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 M27C801 is in the programming mode when V PP input is at 12.75V and
E 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.

PRESTO IIB Programming Algorithm
PRESTO IIB Programming Algorithm allows the
whole array to be programmed with a guaranteed
margin, in a typical time of 52.5 seconds. This can
be achieved with STMicroelectronics M27C801
due to several design innovations to improve programming efficiency and to provide adequate margin for reliability. Before starting the programming
the internal MARGIN MODE circuit is set in order
to guarantee that each cell is programmed with
enough margin. Then a sequence of 50µs program pulses are applied to each byte until a correct verify occurs. No overprogram pulses are
applied since the verify in MARGIN MODE provides the necessary margin.
Program Inhibit
Programming of multiple M27C801s in parallel
with different data is also easily accomplished. Except for E, all like inputs including GVPP of the parallel M27C801 may be common. A TTL low level
pulse applied to a M27C801's E input, with VPP at
12.75V, will program that M27C801. A high level E
input inhibits the other M27C801s 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 G
at V IL. Data should be verified with tELQV after the
falling edge of E.
9/16
M27C801
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 M27C801. To activate the ES
mode, the programming equipment must force
11.5V to 12.5V on address line A9 of the
M27C801. 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 = V IL) represents the manufacturer code and byte 1 (A0 = V IH) the device
identifier code. For the STMicroelectronics
M27C801, these two identifier bytes are given in
Table 4 and can be read-out on outputs Q7 to Q0.
10/16
ERASURE OPERATION (applies to UV EPROM)
The erasure characteristics of the M27C801 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
M27C801 in about 3 years, while it would take approximately 1 week to cause erasure when exposed to direct sunlight. If the M27C801 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 M27C801 window to
prevent unintentional erasure. The recommended
erasure procedure for the M27C801 is exposure to
short wave ultraviolet light which has wavelength
2537 Å. The integrated dose (i.e. UV intensity x
exposure time) for erasure should be a minimum
of 30 W-sec/cm2. The erasure time with this dosage is approximately 30 to 40 minutes using an ultraviolet lamp with 12000 µW/cm 2 power rating.
The M27C801 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.
