数据手册.pdfEPROM（一次性可编程），Atmel### EPROM OTP（一次性可编程）这些 EPROM（可擦除可编程只读存储器）设备包含相同的芯片，并用与其 UV 可擦除同类产品相同的方法进行编程。 但是，由于封装不包含窗口，它们不可擦除且不可重新编程。
Description
The AT27C080 chip is a low-power, high-performance 8,388,608-bit one-time programmable read only memory OTP EPROM organized as 1M by 8 bits. The AT27C080 requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 90 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems.
