CHAPTER 2 POWER SUPPLY SYSTEM
2.1
Overview
MSM64P155 (OTP version) is manufactured using EPROM process for the N-well that
is different from the P-well CMOS structure of the mask ROM of MSM64155A (mask
ROM). Because of this, the polarity of the power supply system is completely reversed
when compared to the mask ROM. In addition, note that the names of the power supply
pins have also been changed.
Table 2-1 shows a table of the power supply pin functions and Table 2-2 shows the
differences between MSM64155A and MSM64P155.
