    | Partname: | AT27C400 |  | Description: | 4-Megabit 256K x 16 or 512K x 8 OTP EPROM |  | Manufacturer: | Atmel Corporation |  | Datasheet: | PDF (184K). Click here to download *)
 |  | The AT27C400 is a low-power, high-performance 4,194,304-bit one-time programmable 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 32bit microprocessor systems. PDIP Top View |  |  Click here to download AT27C400 Datasheet*)
