MICROCHIP AT27C512R-70JU

The AT27C512R-70JU is a low-power high-performance 524288-bit One-Time Programmable Read-Only Memory (OTP EPROM) organized as 64K by 8-bit. It requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 70ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. The scaled CMOS technology provides high speed, lower active power consumption and significantly faster programming. Power consumption is typically only 8mA in active mode and less than 10µA in standby mode. The device features 2-line control (CE, OE) to give designers the flexibility to prevent bus contention. With 64K byte storage capability, the AT27C512R allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. The rapid programming algorithm reduces the time required to program the part and guarantees reliable programming.
