A5 Dec 29, 2003 Features - Multiple display modes (16-segment & 12-digit to 24-segment & 4-digit) - Key scanning (16 x 2 matrix) - Dimming circuit (eight steps) - High-voltage output ( V EE (max) = VDD – 35V ) - 4 channel LED ports - No external resistors necessary for driver outputs (P-ch open-drain + pull-down resistor output) - Serial interface (CLK, STB, D IN, DOUT) - Package: 44-pin plastic QFP and LQFP General Description The AD6315 is a VFD (Vacuum Fluorescent Display or fluorescent Indicator Panel) driver that is driven on a 1/4- to 1/12- duty factor. It consists of 16 segments and 4 grids output lines, 8 segments / grid output driving lines, a display memory, a control circuit, and a key scan circuit. Serial data is input to the AD6315 through a 3-wire serial interface. This VFD driver is ideal as a peripheral device for a single-chip microcomputer.

1/4- to 1/12 Duty VFD Controller/Driver Anachip Corp. www.anachip.com.tw Rev. A5 Dec 29, 2003 Pin Descriptions Symbol Name No. Description DIN Data input 7 Input serial data at rising edge of shift clock, starting from the low order bit. DOUT Data output 6 Output serial data at the falling edge of the shift clock, starting from low order bit. This is N-ch open-drain output pin. STB Strobe 9 Initializes serial interface at the rising or falling edge of the AD6315. It then waits for reception of a command. Data input after STB falling is processed as a command. While command data is processed, current processing is stopped, and the serial interface is initialized. While STB is high, CLK is ignored. CLK Clock input 8 Reads serial data at the rising edge, and outputs data at the falling edge. OSC Oscillator pin 5 Connect resistor in between this pin and Vss to set up the oscillation frequency.

The data of bits after the 5th bit are ignored. b3 b2 b1 b0 LSBMSB Don't care LED1 LED2 LED3 LED4 Note: On power application, all the LED ports are “L” output. (4) Commands Commands set the display mode and status of the VFD driver. The first 1 byte input to the AD6315 through the DIN pin after the STB pin has fallen is regarded as a command. If STB is set high while commands/data are tr ansmitted, serial communication is initialized, and the commands/data being transmitted are invalid (however, the commands/data previously transmitted remain valid).

A5 Dec 29, 2003 (Ⅰ) Display mode setting commands These commands initialize the AD6315 and select the number of segments and the number of grids (1/4- to 1/12- duty, 16 segments to 24 segments). When these commands are executed, the display is forcibly turned off, and key scanning is also stopped. To resume display, the display command “ON” must be executed. If the same mode is selected, however, nothing happens. b2 b1 b0 LSBMSB Don't care Display mode settings 0000: 4digits 24segments 0001: 5digits 23segments 0010: 6digits 22segments 0011: 7digits 21segments 0100: 8digits 20segments 0101: 9digits 19segments 0110: 10digits 18segments 0111: 11digits 17segments 1xxx : 12digits 16segments Note: On power application, the 12-digit, 16-segment mode is selected.
