Pin DescriptionPad Name I/O Description
ROW0~ROW23 O Line drivers. These pins drive the LEDs.
ROW24/COM15~ ROW31/COM8 O Drive LED outputs or common outputs. Each COM pin is double bonded.
COM0~COM7 O Common outputs. Each COM pin is double bonded.
SYNC I/O
If the RC Master Mode or EXT CLK Master Mode command is programmed, the synchronous signal is output to SYN pin. If the Slave Mode command is programmed, the synchronous signal is input from SYN pin.
OSC I/O
If the RC Master Mode command is programmed, the system clock source is from on-chip RC oscillator and system clock is output to OSC pin. If the Slave Mode or EXT CLK Master Mode command is programmed, the system clock source is input from external clock via the OSC pin.
DATA I/O Serial data input or output with pull-high resistor
WR I WRITE clock input with pull-high resistor Data on the DATA lines are latched into the HT1632C on the rising edge of the WR signal.
RD IREAD clock input with pull-high resistor. The HT1632C RAM data is clocked out on the falling edge of the RD signal. The clocked out data will appear on the DATA line. The host controller can use the next rising edge to latch the clocked out data.
CS I
Chip select input with pull-high resistor When the CS line is high, the data and command read from or written to the HT1632C is disabled, and the serial interface circuit is also reset. If CS is low, the data and command transmission between the host controller and the HT1632C are all enabled.
VSS — Negative power supply, ground. In the PCB layout, all VSS pins should be connected to the GND plane.
VDD — Positive power supply. In the PCB layout, all VDD pins should be connected to the power plane.
