7 / 15 page N567KXXX Publication Release Date: Feb. 2014 - 7 - Revision A12 4. PIN DESCRIPTION PIN NAME I/O FUNCTION /RESET In IC reset input with an internal pull-up resistor, low active. OSCIN I Main-clock oscillation input for X ’tal mode. Build-in ROSC by mask option. OSCOUT O Main-clock oscillation output for X ’tal. IP00~IP07 In General input port with pull-high selection. Each input pin can be programmed to generate interrupt request and used to release IC from STOP mode. It is provided in N567K240~K330 only. BP00~BP07 I/O General input/output pins. When used as output pin, it can be open –drain or CMOS type and it can sink 25mA for high-current applications. When used as input pin, there may have a pull-high option and generate interrupt request to release IC from STOP mode. When BP07 is used as output pin, it can be the IR transmission carrier for IR applications. Only for N567K240/280/330. BP00/02/04 can be set as 3-pin H/W PWM output with 64-level resolution. They can be paired with BP01/03/05 (also H/W PWM output) respectively with same or opposite phase of output waveform. BP10~BP17 I/O General input/output pins. When used as output pin, it can be open –drain or CMOS type. When used as input pin, there may have a pull-high option and generate interrupt request to release IC from STOP mode. When serial interface management (SIM) is enabled, and set memory type as W55F/W551C, BP10~12 are used to be an interface with the external memory, W55Fxx or W551Cxxx. If set memory to SPI flash, BP10~13 are used to be an interface. BP20~BP27 I/O General input/output pins. When used as output pin, it can be open –drain or CMOS type. When used as input pin, there may have a pull-high option and generate interrupt request to release IC from STOP mode. PWM+/DAC O PWM driver positive output or Current type DAC output PWM- O PWM driver negative output VDD Power Positive power supply for uP and peripherals. VSS Power Negative power supply for uP and peripherals. VDD_SPK Power Positive power supply for speaker driver. VSS_SPK Power Negative power supply for speaker driver. VDD_SIM Power Positive power supply for serial interface Management (SIM) BP10~13 Only providing in N567K240~N567K330. For non-SIM application, it should be connect to VDD to keep normal standby current. VDD_OSC Power Positive power supply for oscillator. Only providing in N567K240~N567K330. It must be connected to VDD. VSS_OSC Power Negative power supply for oscillator. Only providing in N567K240~N567K330. This pad must be connected to VSS. |
