HT1622 -- RAM Mapping 32x8 LCD Controller
for I/O MCU |
|
| 概要 |
|
HT1622 is a peripheral device specially designed for
I/O type MCU used to expand the display capability.
The max. display segment of the device are 256
patterns (32x8). It also supports serial interface,
buzzer sound, watchdog timer or time base timer
functions. The HT1622 is a memory mapping and
multi-function LCD controller. The software
configuration feature of the HT1622 make it suitable
for multiple LCD applications including LCD modules
and display subsystems. Only three lines are
required for the interface between the host
controller and the HT1622. The HT162X series have
many kinds of products that match various
applications. |
