Description: The HT1632C is a memory mapping LED display controller/driver, which can select a number of ROW and commons. These are 32 ROW & 8 Commons and 24 ROW & 16 Commons. The device supports 16-gradation LEDs for each out line using PWM control with software instructions. A serial interface is conveniently provided for the command mode and data mode.
Only three or four lines are required for the interface between the host controller and the HT1632C.
The display can be extended by cascading the HT1632C for wider applications.
