Description
The AT27C1024 is a low-power, high-performance 1,048,576 bit one-time program-
mable read only memory (OTP EPROM) organized 64K 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
organization make this part ideal for high-performance 16- and 32-bit microprocessor
systems.

1. VCC must be applied simultaneously or before VPP, and removed simultaneously or after VPP.
2. VPP may be connected directly to VCC, except during programming. The supply current would then be the sum of ICC and
IPP.

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 100 µsec ± 5%.
