On-Board Programming

The M27C516 can be directly programmed in the

application circuit. See the relevant Application

Note AN620.

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 correspondingprogramming algorithm. The

ES mode is functional in the 25

°C ± 5°C ambient

temperature range that is required when program-

ming the M27C516. To activate the ES mode, the

programming equipmentmust force 11.5V to 12.5V

on address line A9 of the M27C516.

Two identifier bytes may then be sequenced from

the device outputs by toggling address line A0 from

STMicroelectronics M27C516, these two identifier

bytes are given in Table 4 and can be read-out on

outputs Q0 to Q7.
