Summary description
Summary description
The M27C160 is a 16-Mbit EPROM offered in two ranges UV (Ultraviolet Erase) and OTP
(One-Time Programmable). It is ideally suited for microprocessor systems requiring large
data or program storage and is organized as either 2 Mbit words of 8 bits or 1 Mbit word of
16 bits. The pin-out is compatible with a 16-Mbit Mask ROM.
The FDIP42W (window ceramic frit-seal package) has a transparent lid which enables the
user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be
written rapidly to the device by following the programming procedure.
For applications where the content is programmed only one time and erasure is not
required, the M27C160 is offered in PDIP42, SDIP42, PLCC44 and SO44 packages.
In order to meet environmental requirements, ST offers the M27C160 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.

2.1
Read mode
The M27C160 has two organisations, Word-wide and Byte-wide. The organisation is
selected by the signal level on the BYTEVPP pin. When BYTEVPP is at VIH the Word-wide
organisation is selected and the Q15A–1 pin is used for Q15 Data Output. When the
BYTEVPP pin is at VIL the Byte-wide organisation is selected and the Q15A–1 pin is used for
the Address Input A–1. When the memory is logically regarded as 16 bit wide, but read in
the Byte-wide organisation, then with A–1 at VIL the lower 8 bits of the 16 bit data are
selected and with A–1 at VIH the upper 8 bits of the 16 bit data are selected.
The M27C160 has two control functions, both of which must be logically active in order to
obtain data at the outputs. In addition the Word-wide or Byte- wide organisation must be
selected.
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-tGLQV.
2.2
Standby mode
The M27C160 has a standby mode which reduces the active current from 50mA to 100µA.
The M27C160 is placed in the standby mode by applying a CMOS high signal to the E input.
8/26
M27C160
Device description
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 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 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 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 selected 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 purpose of
this 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 M27C160 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
M27C160 is in the programming mode when VPP input is at 12.5V, G is at VIH and E is
pulsed to VIL. The data to be programmed is applied to 16 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.
2.6
Presto III programming algorithm
The Presto III Programming Algorithm allows the whole array to be programed with a
guaranteed margin in a typical time of 52.5 seconds. Programming with Presto III consists of
9/26
Device description
M27C160
applying a sequence of 50µs program pulses to each word until a correct verify occurs (see
Figure 5). During programing and verify operation a Margin mode circuit is automatically
activated to guarantee that each cell is programed with enough margin. No overprogram
pulse is applied since the verify in Margin mode provides the necessary margin to each
programmed cell.

2.7
Program Inhibit
Programming of multiple M27C160s in parallel with different data is also easily
accomplished. Except for E, all like inputs including G of the parallel M27C160 may be
common. A TTL low level pulse applied to a M27C160's E input and VPP at 12.5V, will
program that M27C160. A high level E input inhibits the other M27C160s 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 at VIH and G at VIL, VPP at 12.5V
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°C ± 5°C
10/26
M27C160
Device description
ambient temperature range that is required when programming the M27C160. To activate
the ES mode, the programming equipment must force 11.5V to 12.5V on address line A9 of
the M27C160, with VPP = VCC = 5V. 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 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 M27C160,
these two identifier bytes are given in Table 3 and can be read-out on outputs Q7 to Q0.

Erasure operation (applies to UV EPROM)
The erasure characteristics of the M27C160 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 M27C160 in about 3 years, while it would take approximately 1 week to
cause erasure when exposed to direct sunlight. If the M27C160 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 M27C160 window to prevent unintentional erasure. The recommended
erasure procedure for M27C160 is exposure to short wave ultraviolet light which has a
wavelength of 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/cm2 power rating. The M27C160
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.
