General Description
SC16312 is a VFD (Vacuum Fluorescent Display) controller driver that is driven on a 1/4 to 1/11
duty factor. It consists of 11 segment output lines, 6 grid output lines, 5 segment/grid output drives,4 LED
output ports, a control circuit, a display memory, and a key scancircuit.
Serial data inputs to the SC16312 through a three-line serial interface. This VFD controller/driver is
ideal as a peripheral device for an MCU.

Dimming Control
SC16312 porvides 8-step dimmer function on display by controlling the 3-bit binary command code.
The full pulse width of grid signal is divides into 16 uniform sections by PWM(pulse width
modulation )technology.
The 16 uniform sections available form 8 steps dimmer via 3-bit binary code. The 8-step dimmer
includes 1/16, 2/16, 4/16, 10/16, 11/16, 12/16, 13/16, and 14/16. The 1/16 pulse width indicates minimum
lightness. The 14/16 pulse width represents maximum lightness. The 14/16 pulse width represents
maximum lightness. (Refer to the display control command).
Key matrix and key-input data storage RAM
The key matrix scans the series key states at each level of the key strobe signal
(S0/K0~S5/K5)output of the :SC16312. The key strobe signal outputs are time-multiplexed signals from
S0/K0~S5/K5. The states of inputs K0~K3 are sampled by strobe signal S0/K0~S5/K5 and latched into
the register.
The key matrix is made up of a 6x4 matrix, as shown below.
Detail
The data of each key is stored as illustrated below. And is read with the read command, starting form
the least significant bit.
