The AT27C256R-45PU is a 256 kbit (32k x 8) one-time programmable EPROM memory chip (OTP EPROM) that uses CMOS technology and comes in a 28-pin through-hole DIP package. The memory allows fast reading with an access time under 45 ns, eliminating the need for wait states in microprocessor systems.
In normal read mode, the component requires a single 5 V supply (ranging from 4.5 to 5.5 V). Current consumption is typically 8 mA in active mode and typically under 10 μA (up to 100 μA) in standby mode. To prevent bus contention, the device features two-line control (CE and OE).
The memory chip features CMOS- and TTL-compatible inputs and outputs, 2000 V ESD protection, an integrated product identification code, and a rapid programming algorithm with a typical speed of 100 μs per byte. The operating temperature range is -40 °C to +85 °C.
