Connection point for 0.1 µF Capacitor. CBYP2 11 0.1 µF Reference Bypass Capacitor for DAC2. Connection point for 0.1 µF Capacitor. CBYP3 6 0.1 µF Reference Bypass Capacitor for DAC3. Connection point for 0.1 µF Capacitor. CBYP4 3 0.1 µF Reference Bypass Capacitor for DAC4. Connection point for 0.1 µF Capacitor. RREF1 18 1210 Ohm Current Setting Resistor. Connection point for external current setting resistor for DAC1. The resistor is connected between RREF1 and GND. Output video levels are inversely proportional to the value of RREF1. RREF2 13 1210 Ohm Current Setting Resistor. Connection point for external current setting resistor for DAC2. The resistor is connected between RREF2 and GND. Output video levels are inversely proportional to the value of RREF2. RREF3 8 1210 Ohm Current Setting Resistor. Connection point for external current setting resistor for DAC3. The resistor is connected between RREF3 and GND. Output video levels are inversely proportional to the value of RREF3. RREF4 99 1210 Ohm Current Setting Resistor. Connection point for external current setting resistor for DAC4. The resistor is connected between RREF4 and GND. Output video levels are inversely proportional to the value of RREF4. VREF 98 1.235 V Voltage Reference Input. External voltage reference input, internal voltage reference output, nominally 1.235V. MPU INTERFACE (13 pins) A[1:0]/SA[1:0] 61, 62 TTL When SER (HIGH), OLUT/control/pointer address. When SER (LOW), SA[1:0] of serial chip address SA[6:0]. CS/SCL 59 TTL/R-BUS When SER (HIGH), microprocessor port clock. When SER (LOW), serial bus clock. D[7:0] 63–70 TTL Bi-directional Data Bus. RW/SDA 60 TTL/R-BUS When SER (HIGH), read/write control. When SER (LOW), serial bus bi-directional data. SER 58 TTL Microprocessor Select. When LOW, the serial interface is enabled. When HIGH, the parallel interface is enabled. POWER & GROUND (17 pins) AGND 4, 9, 14, 100 0.0V Analog ground DGND 26, 40, 53, 71, 97 0.0V Digital ground VDD 39, 54, 72, 96 +5.0V Digital positive power supply VDDA 1, 7, 12, 17 +5.0V Analog positive power supply Pin Definitions (continued) Pin Name Pin Number Value Description |
