DESCRIPTION
The LH1594/LH1595 are LCD drivers with a built-in character ROM suitable for driving small scale dotmatrix LCD panels, and which are capable of being directly connected to the bus line of a microcomputer. The 8-bit parallel or serial data transferred from a microcomputer is used to
generate LCD drive signals for displaying characters. Incorporating a character ROM which has font characters configured in the format of 5 x 8 dots and a character RAM which allows the user to define characters, the LH1594/LH1595 provide a higher freedom of display. Since the LH1594/LH1595 have 80 output pins for a segment drive circuit and 17 output pins for a common drive circuit in a single chip, a display system for 16 characters x 2 lines can be implemented easily. The LH1594/LH1595 enable an LCD system for battery-operated, handcarrying information equipment by securing lower power consumption and wider operating voltage
range.

LZ0P3817 - 1/4-type Built-in Lens Color CMOS Image Sensor with 350 k Pixels

■Description
IR2E51Y incorporates white LED driver with auto brightness control.
This IC is equipped with charge pump DC/DC converter.
Input voltage is boosted into CPO by a charge pump circuit.
This IC maintains high efficiency since the charge pump circuit automatically selects 1x or 1.5x charge pump mode depending on input voltage and load.
It contains 4 white LED drivers to drive the main-LCD backlight, 2 white LED drivers for sub-LCD backlight and RGB-LED drivers.
All LED are connected in parallel.
With peripheral ambient light sensor, this IC automatically adjusts white LED brightness to ambient brightness.
This IC supports I2C-Bus interface.
This product is optimum for use as the backlight white LED driver IC for cellular phone and PDA applications, etc.
