2. Power Supply System
2.1 Summary
The MSM64P164 (OTP chip) is manufactured using EPROM process for the N-well that is
different from the P-well CMOS structure of the mask ROM of MSM64164 (mask ROM chip).
Because of this, the polarity of the power supply system is completely reversed when
compared to the mask ROM chip. 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 the MSM64164 and the MSM64P164.
