AT27LV512A数据手册集成电路（IC）的存储器规格书PDF

描述 Description

The Microchip AT27LV512Ais a high-performance, low-power, low-voltage 512-Kbit One Time Programmable EPROMorganized as 64-Kbit x 8. Requiring a single power supply in the range of 3.0Vto 3.6V in normal read mode operation any byte canbe accessed in less than 90 ns. With typical power consumption of only 18 mW at5 MHz and VCC =3.3V, the AT27LV512A consumes less than one-fifth the power of a standard, 5VEPROM. Standby mode supply current is typically less than 1 μA at 3.3V,making it ideal for fast, portable systems using battery power..
