M27C2001
Summary description
The M27C2001 is a high speed 2 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 262,144 by 8 bits.
The FDIP32W (window ceramic frit-seal package) has a transparent lids which allow 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 M27C2001 is offered in PDIP32, PLCC32 and TSOP32 (8 x 20 mm) packages.
In order to meet environmental requirements, ST offers the M27C2001 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.

Device operation
Device operation
The operating modes of the M27C2001 are listed in the Table 2. A single power supply is
required in the read mode. All inputs are TTL levels except for V PP and 12V on A9 for
Electronic Signature.
2.1
Read Mode
The M27C2001 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 (tAVQV) is equal to the delay from E to output (tELQV). Data is
available at the output after a delay of tGLQV from the falling edge of G, assuming that E has
been low and the addresses have been stable for at least tAVQV-t GLQV.
2.2
Standby Mode
The M27C2001 has a standby mode which reduces the supply current from 30mA to 100µA.
The M27C2001 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 G input.
2.3
Two Line Output Control
Because EPROM devices 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.
2.4
System Considerations
The power switching characteristics of Advanced CMOS EPROMs require careful
decoupling of the devices. The supply current, ICC, 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 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
8/25
Device operation
M27C2001
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 V CC 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.
2.5
Programming
When delivered (and after each erasure for UV EPROM), all bits of the M27C2001 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 only way to change a '0' to a '1' is by die exposure to ultraviolet light (UV EPROM). The
M27C2001 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 8 bits in parallel to the data output
pins. The levels required for the address and data inputs are TTL. V CC is specified to be
6.25 ± 0.25V.
2.6
PRESTO II Programming Algorithm
PRESTO II Programming Algorithm allows the whole array to be programmed with a
guaranteed margin, in a typical time of 26.5 seconds. Programming with PRESTO II
consists of applying a sequence of 100µs program pulses to each byte until a correct verify
occurs (see Figure 5). 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 provides the
necessary margin to each programmed cell.

Device operation
Program Inhibit
Programming of multiple M27C2001s in parallel with different data is also easily
accomplished. Except for E, all like inputs including G of the parallel M27C2001 may be
common. A TTL low level pulse applied to a M27C2001's P input, with E low and VPP at
12.75V, will program that M27C2001. A high level E input inhibits the other M27C2001s from
being programmed.
2.8
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.
2.9
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 ± 5°C ambient
temperature range that is required when programming the M27C2001. To activate the ES
mode, the programming equipment must force 11.5 to 12.5V on address line A9 of the
M27C2001 with V PP = VCC = 5V. Two identifier bytes may then be sequenced from the
device outputs by toggling address line A0 from VIL to V IH. All other address lines must be
held at VIL during Electronic Signature mode. Byte 0 (A0 = VIL) represents the manufacturer
code and byte 1 (A0 = VIH) the device identifier code. For the STMicroelectronics
M27C2001, these two identifier bytes are given in Table 3 and can be read-out on outputs
Q7 to Q0.
2.10
Erasure operation (applies to UV EPROM)
The erasure characteristics of the M27C2001 are such that erasure begins when the cells
are exposed to light with wavelengths shorter than approximately 4000Å. It should be noted
that sunlight and some type of fluorescent lamps have wavelengths in the 3000-4000Å
range. Data shows that constant exposure to room level fluorescent lighting could erase a
typical M27C2001 in about 3 years, while it would take approximately 1 week to cause
erasure when exposed to direct sunlight. If the M27C2001 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 M27C2001 window to prevent unintentional erasure. The recommended erasure
procedure for the M27C2001 is exposure to short wave ultraviolet light which has
wavelength of 2537Å. The integrated dose (i.e. UV intensity x exposure time) for erasure
should be a minimum of 15W-s/cm2. The erasure time with this dosage is approximately 15
to 20 minutes using an ultraviolet lamp with 12000µW/cm2 power rating. The M27C2001
should be placed within 2.5cm (1 inch) of the lamp tubes during the erasure. Some lamps
have a filter on their tubes which should be removed before erasure.
