VFD DRIVER : IC401 (V6313)
1. INTRODUCTION
With following functions, IC401 realizes the serial communication with MPEG (ES6629)
according to software.
CMOS Technology
Key Scanning (12 x 2 matrix)
8-step Dimming Circuit
Multi Display mode (10digit 16segment)
LED port supportable (5Ch, max 20mA)
I2C EPROM interface
POWER SW 1Port
2. INPUT/OUTPUT TERMINAL
INPUT : Receive VSTB, VCLK and VDAT from MPEG (ES6629) and scan key input at
voltage level.
OUTPUT : Output VDAT to MPEG (ES6629) and operate VFD.
With key value stored at EPROM by direct I2C communication, power control by
remote control signal is possible.
DESCRIPTION OF FRONT OPERATION
1. KEY SCAN & VFD DRIVER (V6313) INTERFACE
2. DESCRIPTION OF OPERATION
If a user presses a key while MPEG chip (ES6629) is scanning a key thru VFD Driver IC (V6313),
V6313 receives key input and if it inputs serially the received data to MPEG chip (ES6629), it
analyzes and proceed the command.
Operate the action according to an input command.
After EPROM reads and compares the remote control code received from IR remote control
sensor, power is controlled using PSW in case of KEY code.
