IC 27C512-12 EPROM 512K-Bit 120ns UV EPROM
IC 27C512-12 EPROM 512K-Bit 120ns UV EPROM, 512 Kbit (64K x8) UV EPROM The M27C512 is a 512 Kbit UV (ultra violet erase) EPROM. It is ideally suited for applications where fast turn-around and pattern experimentation are important requirements and is organized as 65536 by 8 bits. The FDIP28W (window ceramic frit-seal package) has transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programming procedure. Features 5V A 10% supply voltage in read operation Access time: 120 ns Low power "CMOS" consumption: Active current 30 mA Standby current 100 AmicroA Programming voltage: 12.75 V A 0.25 V Programming time around 6 s. Electronic Signature Manufacturer code: 20h Device code: 3Dh
