DESCRIPTION
The M27V320 is a low voltage 32 Mbit EPROM of-
fered in the OTP range (one time programmable).
It is ideally suited for microprocessor systems re-
quiring large data or program storage. It is organ-
ised as either 4 MWords of 8 bit or 2 MWords of 16
bit. The pin-out is compatible with the 32 Mbit
Mask ROM.
The M27V320 is offered in SO44 and TSOP48
(12 x 20 mm) packages.

Two Line Output Control
Because EPROMs are usually used in larger
memory arrays, this product features a 2 line con-
trol function which accommodates the use of mul-
tiple 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 prima-
ry device selecting function, while GVPP 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 deselect-
ed 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
supplies to the devices. The supply current ICC
has three segments of importance to the system
designer: the standby current, the active current
and the transient 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 outputs. The associated transient
voltage peaks can be suppressed by complying
with the two line output control and by properly se-
lected decoupling capacitors. It is recommended
that a 0.1µF ceramic capacitor is used on every
device between VCC and VSS. This should be a
high frequency type of low inherent inductance
and should be placed as close as possible to the
device. In addition, a 4.7µF electrolytic capacitor
should be used between VCC and VSS for every
eight devices. This capacitor should be mounted
near the power supply connection point. The pur-
pose of this capacitor is to overcome the voltage
drop caused by the inductive effects of PCB trac-
es.

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 am-
bient temperature range that is required when pro-
gramming the M27V320. To activate the ES mode,
the programming equipment must force 11.5V to
12.5V on address line A9 of the M27V320, with
VPP = VCC = 5V. Two identifier bytes may then be
sequenced from the device outputs by toggling ad-
dress line A0 from VIL to VIH. All other address
lines must be held at VIL during Electronic Signa-
ture mode.
Byte 0 (A0 = VIL) represents the manufacturer
code and byte 1 (A0 = VIH) the device identifier
code. For the STMicroelectronics M27V320, these
two identifier bytes are given in Table 4 and can be
read-out on outputs Q7 to Q0.
