... OTP (one time programmable ideally suited for microprocessor systems and is orga- nized as 32,768 by 8 bits. The M27W256 operates in the read mode with a supply voltage as low as 3V. The decrease in op- erating power allows either a reduction of the size of the battery or an increase in the time between battery recharges ...
