1. DESCRIPTION
The S1D12304/12305 Series is a dot matrix LCD
controller driver for character display, and can display a
maximum of 48 characters, 4 user-defined characters,
and a maxi-mum of 48 symbols by means of 4-bit, 8-bit
or serial data sent from a microcomputer.
A built-in character generator ROM is prepared for 256
character types, and each character font consists of 5 × 7
dots. A user-defined character RAM for four characters
of 5 × 7 dots are incorporated, and a symbol register is
also incorporated. With these, it is possible to apply this
Series to display with a high degree of freedom. This
Series can operate handy units with a minimum power
consumption by means of its low power consumption
and sleep mode.
S1D12304, and 12305 depending on the duty of use and
the number of display columns.
2. FEATURES

48 characters + 4 user-defined characters + 48 sym-
bols
• CG ROM (for up to 256 characters), CG RAM (4
characters), and symbol register (48 symbols)
• Number of display columns × number of lines
(12 columns + 2 segment for signal) × 4 lines + 48
symbols: S1D12304
(12 columns + 2 segment for signal) × 2 lines + 48
symbols: S1D12305
• CR oscillation circuit (on-chip C and R)
