• Manufacturer Part Number: S1D15715
• Description: Liquid Crystal Display =lcd Driver
• Manufacturer: Epson Electronics America, Inc.

1. DESCRIPTION
S1D15715 Series is a single-chip liquid crystal display (=LCD) driver for dot matrix LCDs that can be
connected directly to a microprocessor (=MPU) bus.
It accepts 8-bit parallel or serial display data from a MPU, stores it in an on-chip display data RAM (=DDRAM),
and generates a LCD drive signal independent of the MPU clock.
The use of the on-chip DDRAM of 33×102 bits and a one-to-one correspondence between LCD panel pixel dots
and on-chip DDRAM bits offer high flexibility in graphic display.
The S1D15715 is equipped with 17 circuits of common output and 102 circuits of segment output, and displays
in 17×102 dots. The S1D15716 is equipped with 9 circuits of common output and 102 circuits of segment
output, and displays in 9×102 dots. The S1D15717 is equipped with 33 circuits of common output and 102
circuits of segment output, and displays in33×102 dots.
S1D15715 series can perform reading and writing of the display data RAM with minimum power consumption
since it does not require external operation clock. Moreover, since the series is equipped with
low-power-consumption and highly efficient LCD driver power supply and display clock CR oscillation circuit,
it is suited for display system of the high-performance handy device and in-vehicle device.
