■ DESCRIPTION
The SED1560 series is a single-chip LCD driver for dot-matrix liquid crystal displays. It accepts serial or 8-bit
parallel display data directly from a microprocessor and stores data in an on-chip 166 × 65-bit RAM.
The SED1560 features 167 common and segment outputs to drive either a 65 × 102-pixel display (4 rows × 6
columns with 16 × 16-pixel characters) or a 33 × 134-pixel display (2 rows × 8 columns with 16 × 16-pixel
characters) or a 17 × 150-pixel display (1 row × 9 columns with 16 × 16 characters). In addition, two SED1560s
can be connected together to drive a 65 × 268-pixel graphics display panel.
The SED 1560 series can read and write RAM data with the minimum current consumption as it does not require
any external operation clock. Also, it has a built-in LCD power supply featuring the very low current consumption
and, therefore, the display system of a high-performance but handy instrument can be realized by use of the
minimum current consumption and LSI chip configuration.
The SED 1560 Series has the SED1560, SED1561 and SED1562 available according to the duty.
