GENERAL DESCRIPTION

The MSM6562B-xx controls a character type dot matrix LCD in combination with an 8-bit or 4- bit microcontroller.

The MSM6562B-xx can control a display of up to 40 characters. With the display data serial transfer function, the MSM6562B-xx, when used in combination with the character extension IC (MSM5259), can control a maximum of 80 characters.

FEATURES

• Easy interface with an 8-bit or 4-bit microcontroller.

• Dot matrix LCD controller driver for 5 x 7 dots font or 5 x 10 dots font.

• Automatic power ON reset.

• 16 COMMON signal drivers and 100 SEGMENT signal drivers are built in.

• Can control up to 80 characters when used in combination with MSM5259.

• Built-in character generator ROM for 160 characters with 5 x 7 dots font and 32 characters with 5 x 10 dots font.

• Character patterns can be programmed by CG RAM. (5 x 8 dots font: 8 kinds, 5 x 11 dots font: 4 kinds)

• 1/8 duty (1 line; 5 x 7 dots + cursor), 1/11 duty (1 line; 5 x 10 dots + cursor), or 1/16 duty (2 lines; 5 x 7 dots + cursor) selectable.

• Built-in RC oscillation circuit by an external resistor or an internal resistor.

• Built-in bias dividing resistors for LCD driving.

• Built-in contrast adjusting circuit.

• Bidirectional transfer available on segment output.

• Aluminum pad chip (Product name: MSM6562B-xx)
