GENERAL DESCRIPTION
The MX27C2000 is a 5V only, 2M-bit, One Time
Programmable Read Only Memory. It is organized as
256K words by 8 bits per word, operates from a single +
5 volt supply, has a static standby mode, and features
fast single address location programming. All program-
ming signals are TTL levels, requiring a single pulse. For
programming outside from the system, existing EPROM
programmers may be used. The MX27C2000 supports
a intelligent fast programming algorithm which can result
in programming time of less than one minute.
This EPROM is packaged in industry standard 32 pin
dual-in-line packages, 32 lead SOP, 32 lead PLCC and
32 lead TSOP (I) packages.

TWO-LINE OUTPUT CONTROL FUNCTION
To accommodate multiple memory connections, a two-
line control function is provided to allow for:
1. Low memory power dissipation,
2. Assurance that output bus contention will not
occur.
It is recommended that CE be decoded and used as the
primary device-selecting function, while OE be made a
common connection to all devices in the array and
connected to the READ line from the system control bus.
This assures that all deselected memory devices are in
their low-power standby mode and that the output pins are
only active when data is desired from a particular memory
device.
SYSTEM CONSIDERATIONS
During the switch between active and standby
conditions, transient current peaks are produced on the
rising and falling edges of Chip Enable. The magnitude
of these transient current peaks is dependent on the
output capacitance loading of the device. At a minimum,
a 0.1 uF ceramic capacitor (high frequency, low inherent
inductance) should be used on each device between Vcc
and GND to minimize transient effects. In addition, to
overcome the voltage drop caused by the inductive
effects of the printed circuit board traces on EPROM
arrays, a 4.7 uF bulk electrolytic capacitor should be
used between VCC and GND for each eight devices. The
location of the capacitor should be close to where the
power supply is connected to the array.
