M27V320
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 am-
bient temperature range that is required when pro-
gramming the M27V320. To activate the ES mode,
the programming equipment must force 11.5V to
12.5V on address line A9 of the M27V320, with
V
PP
= V
CC
= 5V. Two identifier bytes may then be
sequenced from the device outputs by toggling ad-
dress line A0 from V
IL
to V
IH
. All other address
lines must be held at V
IL
during Electronic Signa-
ture mode.
Byte 0 (A0 = V
IL
) represents the manufacturer
code and byte 1 (A0 = V
IH
) the device identifier
code. For the STMicroelectronics M27V320, these
two identifier bytes are given in Table 4 and can be
read-out on outputs Q7 to Q0.
