5 / 51 page MB89550A Series 5 s s s s DIFFERENCES AMONG PRODUCTS AND PRECAUTIONS FOR MODEL SELECTION • Package and Model Combinations Note : Compatible with all options (-201/202/203) . • Memory Space • When evaluating chips using piggyback evaluators etc., please take note of the differences among products before making the evaluation. • Current Consumption • When operating at low speed, one-time PROM and EPROM products will consume more current than mask ROM products. However, the current consumption in sleep/stop modes is the same. • For specific details about each package, see "s PACKAGE DIMENSIONS". • For details about power consumption, see "s ELECTRICAL CHARACTERISTICS" . • Mask Options • The available options, and methods of using options, differ according to the model. Be sure to confirm the options from the "s MASK OPTIONS" section. • LCD Drive Step-up Power Circuit The MB89550A series is available with or without the step-up circuit option as a mask option. • Power Supply Path The models in the MB89550A series have two power supply pins, VCC1 and VCC2, with power supply paths that differ according to the model. • Oscillator Startup and Power-on Reset On the MB89PV550A and MB89P558A, oscillator startup and power-on reset are applied at the rise of the VCC2 input. On the MB89558A and MB89557A, oscillator startup and power-on reset are applied at the rise of the VCC1 input.
