OTP (one time programmable) micro-controller

摘要

An OTP (One Time Programmable) micro-controller having a high-data/low-data switching unit adapted to separate input data into high-data and low-data for transmission to an EPROM (erasable programmable read only memory), so that input data of bit number greater than the number of data input/output pins of the micro-controller can be positively write in the EPROM at one time.
