AT27C256R-70JU

The AT27C256R-70JU is a 262144-bit low-power high-performance one-time programmable Read-only Memory (OTP EPROM) IC organized as 32k by 8-bit. It requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 45ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. The scaled CMOS technology provides low active power consumption and fast programming. Power consumption is typically only 8mA in active mode and less than 10μA in standby mode. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention. With 32kB storage capability, allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. The AT27C256R has additional features to ensure high quality and efficient production use. The rapid programming algorithm reduces the time required to program the part and guarantees reliable programming.
