5 / 26 page – 5 – CXA3031Q Pin No. Symbol Pin voltage Equivalent circuit Description 21 HEAD 1B — 22 HEAD 1A — 23 HEAD 0B — 24 HEAD 0A — 25 WCLD 26 WCMD 27 WCHD 5V when XWG = High 3.8V when XWG = Low 28 IESET 29 D.GND — 30 ERA0 — 31 ERA1 — Magnetic head input/output connections. Connect the recording/playback magnetic head to these pins, and connect the center tap to VCC. When the logical voltage for Pin 7 (XS1) is Low, the HEAD1 system is active; when the logical voltage is High, the HEAD0 system is active. 1M write current setting resistor connection. Connect the write current setting resistor RWLD between this pin and VCC to set the write current. 1.6M write current setting resistor connection. Connect the write current setting resistor RWMD between this pin and VCC to set the write current. 2M write current setting resistor connection. Connect the write current setting resistor RWHD between this pin and VCC to set the write current. Erase current setting resistor connection. Connect the erase current setting resistor RE between this pin and VCC to set the erase current. Digital system GND connection. Erase current connection for the HEAD0 system. Erase current connection for the HEAD1 system. A.GND 21 22 23 24 VCC A.GND 1.2V 147 147 147 25 26 27 VCC A.GND 1.2V 147 28 VCC A.GND 30 31 5V when XEG = High 3.8V when XEG = Low |
