CHAPTER 1 OVERVIEW
1.3 Differences among Products
This section describes the differences among the 4 products in the MB89950/950A
series and lists points to note in product selection.
■ Differences among products and points to note for product selection
●
Current consumption
• In the case of the MB89PV950, add the current consumed by the EPROM, which is connected to the top
socket.
• When operated at low speed, the product with a one-time PROM (OTPROM) or an EPROM will
consume more current than the product with mask ROM. However the current consumption in sleep/
stop mode, is the same.
For more information about the package, see Section 1.6 "Package Dimensions".
• For more information about the current consumption, see the electrical characteristics in the Data Sheet.
●
Mask options
Functions that can be selected as options and how to designate these options vary from product to product.
Before using, check Appendix C, "Mask Options".
Take particular care on the following points:
• In the MB89951A and MB89953A, the number of common and segment outputs is specified by Data
Release Form.
• Options are fixed on the MB89PV950. (See Appendix C, "Mask Options")
