µPD6464A,6465

CHARACTER PATTERN DATA

The only difference between the

µPD6464ACS-001 and µPD6464AGT-101 is the package. The character

patterns in the character ROMs of both the models are the same. The same applies to the

µPD6465CS-001

and the

µPD6465GT-101. Both the µPD6464ACS-001 and µPD6464AGT-101 can display 128 types of

alphanumeric characters and character patterns such as Kanji, Hiragana, and Katakana. The

µPD6465CS-001

and

µPD6465GT-101 can display 256 types of them.

The contents of the character ROM (character design) can be changed by mask code option. However, the

characters at addresses 7EH and 7FH (

µPD6464A)/FEH and FFH (µPD6465) are fixed to [Display Off Data] and

[2-byte contiguous command end code], respectively, and no character patterns can be set to these addresses.

Although 10H (

µPD6464A)/6FH (µPD6465) (Blank Data) and 7EH (µPD6464A)/FEH (µPD6465) (Display Off

Data) of the NEC’s standard model are represented in the same manner in the page showing the character

patterns (i.e., these are shown as characters without dots), they have the following differences:

You cannot specify Display Off Data for addresses other than 7EH (

µPD6464A)/FEH (µPD6465) when using

a mask option.

Blank Data, however, can be specified at any address from 00H to 7DH (

µPD6464A)/FDH

(

µPD6465) (address 7FH (µPD6464A)/FFH (µPD6465) cannot be used because it contains the end code for

second-byte continuous input).

The character patterns of the

µPD6464ACS-001 and GT-101/µPD6465CS-001 and GT-101 (NEC’s standard

models) are shown on the following pages.
