The invention provides a wafer-level one time programmable (OTP) chip test method and device. The method includes: according to a test program, performing testing on an OTP chip itself, the test program being burnt in advance in an OTP ROM of the OTP chip for use by a user; and ...
在这里，一次性可编程产品指的是内部的程序内存采用一次性可编程只读存储器（One Time Programmable Read Only Memory，OTPROM，简称OTP）的单片机。OTPROM之资料写入原理同EPROM，可利用编程烧录工具的高电压将资料编程写入。OTP产品为一次性可编程器件，标准产品的程序内存及代码选项区为全空，客户将应用程序代码烧录到...
OTP (One Time Programmable) is a type of memory of the single-chip microcomputer, which means one-time programmable: after the program is burned into the single-chip microcomputer, it cannot be changed and cleared again.Catalogues IntroductionIntroduction As embedded applications become more and ...

Kernel configuration You can manage the OTP driver support through the kernel configuration options: Freescale On-Chip OTP Memory Support(CONFIG_FSL_OTP) This option is enabled as built-in on the defaultConnectCore 6 SBC kernel configuration fileand gives you read-only access to the OTP bits. ...
For one-time programmable devices (such as Actel) the penalty is the price of one chip whilst for erasable devices (such as Xilinx) the devices can simply be reprogrammed. Hence the pressure to simulate 100% is not as great. For those devices that are reprogrammable this results in an ...
