Description
The AT27C516 is a low-power, high performance 524,288 bit one-time programma-
ble read only memory (OTP EPROM) organized 32K by 16 bits. It requires only one
5V power supply in normal read mode operation. Any word can be accessed in less
than 45 ns, eliminating the need for speed reducing WAIT states. The by-16 organi-
zation make this part ideal for high-performance 16 and 32 bit microprocessor sys-
tems.

Notes: 1. VCC must be applied simultaneously or before VPP
and removed simultaneously or after VPP.
2. This parameter is only sampled and is not 100%
tested. Output Float is defined as the point where
data is no longer driven — see timing diagram.
3. Program Pulse width tolerance is 50 µsec ± 5%.
Rapid Programming Algorithm
A 50 µs PGM pulse width is used to program. The address
is set to the first location. VCC is raised to 6.5V and VPP is
raised to 13.0V. Each address is first programmed with
one 50 µs PGM pulse without verification. Then a verifica-
tion / reprogramming loop is executed for each address.
In the event a word fails to pass verification, up to 10 suc-
cessive 50 µs pulses are applied with a verification after
each pulse. If the word fails to verify after 10 pulses have
been applied, the part is considered failed. After the word
verifies properly, the next address is selected until all have
been checked. VPP is then lowered to 5.0V and VCC to
5.0V. All words are read again and compared with the
original data to determine if the device passes or fails.
