产品信息

The LC75806PT is 1/4 duty and 1/3 duty LCD display driver that can directly drive up to 304 segments and can control up to 9 general-purpose output ports. This product also incorporates a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring.

Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)
1/4 duty 1/3 bias and 1/3 duty 1/3 bias drive schemes can be controlled from serial data.
Capable of driving up to 304 segments using 1/4 duty and up to 231 segments using 1/3 duty.
Switching between key scan output and segment output can be controlled from serial data.
The key scan operation enabled/disabled state can be controlled from serial data.
Switching between segment output port and general-purpose output port can be controlled from serial data.
Switching between general-purpose output port, clock output port, and segment output port can be controlled from serial data.
(Up to 9 general-purpose output ports and up to one clock output port)
Serial data I/O supports 'computer control bus' format communication with the system controller. (Support 3.3 V and 5 V operation)
Sleep mode and all segments off functions that are controlled from serial data.
The frame frequency of the common and segment output waveforms can be controlled from serial data.
Switching between RC oscillator operating mode and external clock operationg mode can be controlled from serial data.
Direct display of display data without the use of a decoder provides high generality.
Built-in display contrast adjustment circuit.
Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
RES pin provided for forcibly initializing the IC internal circuits.
