M27C1001 Summary description
1 Summary description
The M27C1001 is a 1 Mbit EPROM offered in the two ranges: UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited for microprocessor systems requiring
large programs and is organized as 131,072 words of 8 bits.
The FDIP32W (window ceramic frit-seal package) has a transparent lid that ena bles the
user to expose the chip to ultra viol et light to er ase the bit pattern. A ne w 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 M27C1001 is off er ed in PDIP32 , PLCC32 an d TSOP32 ( 8 x 20 mm) p ac kages .
In order to meet environmental requirements, ST offers the M27C1001 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.

2.2 Standby mode
The M27C1001 has a standby mode which reduces th e supply current from 30mA to 100µA.
The M27C1001 is placed in the standby mode by applying a CMOS high signal to the E
input. When in the standby mo de, the ou tputs are in a high impedance stat e, indepe ndent 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:
● the lowest possible memory power dissipation,
● complete assurance that output bus contention will not occur.
For the most efficient use of these two control lines, E
