Programming
When delivered (and after each erasure for UV
EPROM), all bits of the M27C64A are in the “1”
state. Data is introduced by selectively program-
ming ”0s” into the desired bit locations. Although
only “0s” will be programmed, both “1s” and “0s”
can be present in the data word. The only way to
change a “0” to a ”1” is by die exposition to ultra-
violet light (UV EPROM). The M27C64A is in the
programming mode when Vpp input is at 12.5V, and
E and P are at TTL-low. The data to be programmed
is applied 8 bits in parallel to the data output pins.
The levels required for the address and data inputs
are TTL. VCC is specified to be 6V
± 0.25V.
High Speed Programming
The high speed programming algorithm, described
in the flowchart, rapidly programs the M27C64A
using an efficient and reliable method, particularly
suited to the production programming environ-
ment. An individual device will take around1 minute
to program.
Program Inhibit
Programming of multiple M27C64A in parallel with
different data is also easily accomplished. Except
for E, all like inputs including G of the parallel
M27C64A may be common. A TTL low level pulse
applied to a M27C64A E input, with P low and VPP
