AT27C256R数据手册集成电路（IC）的存储器规格书PDF

描述 Description

The Microchip AT27C256R is a low-power, high-performance 256-KbitOne Time Programmable EPROM organized as 32-Kbit x 8. Requiring a single 5Vpower supply, in normal read mode operation typical power consumption is only 8mA in active mode and less than 10 μA in standby mode. Any byte can be accessedin less than 45 ns, eliminating the need for speed reducing WAIT states onhigh-performance microprocessor systems.
