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
bient temperature range that is required when pro-
gramming the M27C320. To activate the ES
mode, the programming equipment must force
5 C am-
11.5V to 12.5V on address line A9 of the
M27C320, with V
bytes may then be sequenced from the device out-
puts by toggling address line A0 from V
other address lines must be held at V
Electronic Signature mode.
Byte 0 (A0 = V
code and byte 1 (A0 = V
code. For the STMicroelectronics M27C320, these
two identifier bytes are given in Table 4 and can be
read-out on outputs Q7 to Q0.
