DESCRIPTION
The M27C2001 is a high speed 2 Mbit EPROM of-
fered in the two ranges UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited
for microprocessor systems requiring large pro-
grams and is organised as 262,144 by 8 bits.
The FDIP32W (window ceramic frit-seal package)
and LCCC32W (leadless chip carrier package)
have a transparent lids which allow the user to ex-
pose the chip to ultraviolet light to erase the bit pat-
tern. 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.

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 program-
ming ’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 exposition to ultravio-
let 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 ad-
dress and data inputs are TTL. VCC is specified to
be 6.25V ±0.25V.
