• Manufacturer Part Number: M27C512-90XN6X
• Description: 512 Kbit 64Kb x8 UV EPROM and OTP EPROM
• Manufacturer: STMicroelectronics

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
temperature range that is required when program-
