Pin Description
Pin No.
Pin Name
I/O
Description
1~4 LED3~LED0
O
LED driver output ports. This is a CMOS output pin and maximum driving
current up to +20mA.
5
OSC
I Connected to an external resistor or an RC oscillator circuit.
6
DO
O
Data output pin, output serial data at falling edge of shift clock, starting from
the lower bit. This is N-ch open-drain output pin.
7
DI
I
Data input pin, input serial data at rising edge of shift clock, starting from the
lower bit.
8
CLK
I
Clock input pin. Reads serial data at the rising edge, and outputs data at the
falling edge.
9
CS
Initializes serial interface at the rising or falling edge of the HT16515. Then
I
it waits to receive a command. Data input after CS has fallen is processed,
current processing is stopped, and the serial interface is initialized. While
CS is high, CLK is ignored.
10, 11 Key0, Key1
I Key-in data input to these pins are latched at the end of the display cycle.
12, 44 VSS
¾ Negative power supply, ground
13, 43 VDD
¾ Positive power supply
14~29
Seg1/KS1~Seg16/KS16
O
High voltage output, segment output pins, dual function as key source. This
is PMOS open-drain and pull-low resistor output.
30
VEE
¾ VFD power supply
31~38
Seg17/Grid12~
Seg24/Grid5
O
High voltage output, these pins are selectable for segment or grid output.
This is PMOS open-drain and pull-low resistor output.
39~42 Grid4~Grid1
O
High voltage output, grids output pin. This is PMOS open-drain and pull-low
resistor output.
