ꢀGeneral Description

The AD7312 is a VFD (Vacuum Fluorescent Display) controller/driver with STANDBY controller. It is driven

on a 1/4 to 1/11 duty factor (include key scan). It consists of 5 segment output lines, 6 segment/key scan

output lines, 6 grid output lines, 5 segment/grid output drive lines, 2 LED output ports, a display memory, a

control circuit, and a key scan circuit. In addition, it includes 2 input ports, RMIN and SKEY, RMIN receives

the signal form the STANDBY-KEY of remote sensor, SKEY can be controlled by an external switch. Both of

them and STANBY SCAN-KEY can control the output level (High) of PSV port to realize the STANDBY

function. To leave the standby mode, we can use the 2 remote WAKE_UP-KEY, 3 WAKE_UP SCAN-KEY,

remote STANDBY-KEY, STANDBY-KEY and STANDBY SCAN-KEY to control the output level (Low) of PSV

port to realize the Wake Up function. Serial data is input to the AD7312 through a four-line serial interface.
