M27V512 512 Kbit (64Kb x8) Low Voltage UV EPROM and OTP EPROM is a low voltage 512 Kbit EPROM offered in the two ranges UV (ultra viloet erase) and OTP (one time programmable) by TOSHIBA. It is ideally suited for microprocessor systems and is orga- nized as 65,536 by 8 bits. The M27V512 operates in the read mode with a supply voltage as low as 3V.
The M27V512 is a low‑voltage 512 Kbit EPROM offered in UV‑erase and OTP versions, suitable for microprocessor systems. It is available in FDIP28W, PDIP28, PLCC32 and TSOP28 packages, with a transparent lid for UV erasing.
Key features include a 3 V to 3.6 V read voltage range, 100 ns fast access time, active current of 10 mA at 5 MHz, standby current as low as 10 µA, and a programming voltage of 12.75 V ± 0.25 V. Detailed pin‑out tables, electrical characteristics, and programming procedures are provided.
