9 / 41 page  GPC3XXXAx/Bx/Cx/Dx © Generalplus Technology Inc. Proprietary & Confidential 9 Aug. 28, 2017 Version: 2.3 6.3. Signal Descriptions for GPC3010A/3010C PIN NAME TYPE DESCRIPTION IO Port IOA[7：0] I/O IOA[7：0] is a bi-directional I/O port, can be software programmed as wakeup I/O. 1Mohm || 100Kohm feedback pull low resistor IOA7 shares its pad with IR output. IOA1 shares its pad with external clock input. IOA0 shares its pad with external interrupt input. IOA[2：1] shares its pad with feedback function. IOB[7：0] I/O IOB[7：0] is a bi-directional I/O port, can be software programmed as wakeup I/O. 1Mohm || 100Kohm feedback pull low resistor. IOB[3：0] shares its pad with 256-level PWM output, high sink current. Power & Ground PAD VDD_REGOUT O Regulator output VREF I Reference voltage of analog circuit, must be connected to VDD_REGOUT VDD_REGIN P Power supply regulator voltage input VSS G Ground reference PVDD P PWM driver power, can be greater than or equal to VDD_REGIN PVSS G PWM driver ground reference Others RESB I System reset input, low active (with pull high) NC I Please DON’T bond NC pin (only for GPC3010A). OSC I Frequency control pin for external oscillator, with resistor to VDD_REGIN (only for GPC3010C). TEST I Test pin input, high active (with pull low), and p lease DON’T bond the TEST pin. AUDP, AUDN O PWM output Total: 27 Pins Legend: I = Input O = Output P = Power G = Ground Note1: To ensure that the IC functions properly, please bond all of VDD and VSS pins. Note2: PVDD can be greater than or equal to VDD_REGIN. Note3: Please DON’T bond TEST pin. Note4: NC pin is only for GPC3010A, and p lease DON’T bond NC pin. Note5: OSC pin is only for GPC3010C. |
