Dot Matrix High Duty LCD Driver
q 100 Output q 1/64 to 1/300 in display duty q CMOS High Voltage Resistant Process s OVERVIEW
The SED1670 is a 100 output low-power resistance common (row) driver which is suitable for driving a very high capacity dotmatrix LCD panels upto a duty ratio of 1/300. It is intended to be used in conjunction with the SED1640D or SED1606D as a pair. Since the SED1670 is so designed to drive LCDs over a wide range of voltages, and also the maximum potential V0 of its LCD drive bias voltages is isolated from VDD to allow the LCD driving bias voltages to be externally generated optionally with a high accuracy, it can cope with a wide range of LCD panels. Owing to its pad layout which can minimize its PC boards mounting space in addition to its selectable bidirectional driver output sequence and as many as 100 LCD output segments of high pressure resistance and low output impedance, it is possible to obtain the highest driver working efficiency for the 1/200 duty panel. And the SED1670 can display 65 x 132 panel when used as a common driver of RAM buit-in driver, SED1531.

> > > > Notes: 1. The voltage of V0, V1 and V4 must always satisfy the condition of VDD = V0 = V1 = V4 = V5. 2. Floating of the logic system power during while the LCD drive system power is applied, or exceeding VSS = -2.6 V or more can cause permanent damage to the LSI. Functional operation under these conditions is not implied. Care should be taken to the power supply sequence especially in the system power ON or OFF.
