Atmel AT27C512R-45JU
512K (64K x 8) One-time programmable, read-only memory

Description
The Atmel® AT27C512R is a low power, high performance, 524,288-bit OTP (One-Time-Programmable-Only-Read-Only Memory) EPROM organized as 64K by 8 bits. It requires only a 5V power supply in normal read mode. Each byte can be accessed in less than 70ns, eliminating the need for speed-reducing WAIT states in high performance microprocessor systems. Atmel-scaled CMOS technology offers 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 AT27C512R is available in a choice of JEDEC-approved PDIP and PLCC packages that are industry standard and one-time programmable (OTP). All devices feature two-line control (CE, OE) to give designers the flexibility to avoid bus conflicts. With a memory capacity of 64K bytes, the AT27C512R enables reliable firmware storage and system access without the delays of mass storage media. The AT27C512R has additional features to ensure high quality and efficient production use. The fast programming algorithm reduces the time required to program the component and guarantees reliable programming. The programming time is typically only 100µs/byte. The integrated product identification code electronically identifies the component and the manufacturer. This feature is used by industry standard programmers to select the correct programming algorithms and voltages.
