Notes 1: Refer to “Chapter 12. CONNECTION WITH EXTERNAL DEVICES” for details about the functions and operation
of used pins when expanding a memory. Refer to “Chapter 15. ELECTRICAL CHARACTERISTICS” for timing
requirements.
2: Because the address bus width is used as maximum 24 bits when expanding a memory, strengthen the M37751’s
Vss line. (Refer to “Appendix 8. Examples of noise immunity improvement.”)
