Description
The AT27C400 is a low-power, high-performance 4,194,304-bit one-time programma-
ble read only memory (OTP EPROM) organized as either 256K by 16 or 512K by 8
bits. It requires a single 5V power supply in normal read mode operation. Any word
can be accessed in less than 70 ns, eliminating the need for speed-reducing WAIT
states. The by-16 organization makes this part ideal for high-performance 16- and 32-
bit microprocessor systems.

Notes: 1. The Input Timing Reference is 0.8V for VIL and 2.0V for VIH.
2. tOE and tDFP are characteristics of the device but mist be accomodated by the programmer.
3. When programming the AT27C400, a 0.1 µF capacitor is required across VPP and ground to suppress spurious voltage
transients.
