HT1623 -- RAM Mapping 48x8 LCD Controller
for I/O MCU |
|
| 概要 |
|
THT1623 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 384 patterns (48x8). It also supports serial
interface, buzzer sound, watchdog timer or time base
timer functions. The HT1623 is a memory mapping and
multi-function LCD controller. The software
configuration feature of the HT1623 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 HT1623. The HT162X series have
many kinds of products that match various
applications.. |
