Connect this signal to a 12 MHz series resonant, fundamental mode crystal and 22-33 pF capacitor to GND. Analog VCC. This signal provides power to the analog circuit. 3.3V power source Ground

10、Active high reset. Multiplexed pin whose function is selected by the “RXD0” bit of the PORTCCFG register. If RXD0=0, the pin is the bi-directional I/O port bit PC0. If RXD0 = 1 the pin is the active-high RXD0 from 8051 UART0, which provides data to the UART in all modes. Multiplexed pin whose functi

11、on is selected by the “TXD0” bit of the PORTCCFG register. If TXD0=0, the pin is the bi-directional I/O port bit PC1. If TXD0 = 1 the pin is the active-high TXD0 signal for 8051 UART0, which provides the output clcok in sync mode, and the output data in async mode. Multiplexed pin whose function is

12、selected by the “INT0” bit of the PORTCCFG register. If INT0=0, the pin is the bi-directional I/O port bit PC2. If INT0 = 1 the pin is the active-low 8051 INT0 interrupt input signal, which is either edge triggered (IT0=1) or level triggered (IT0=0). Multiplexed pin whose function is selected by the

13、 “INT1” bit of the PORTCCFG register. If INT1=0, the pin is the bi-directional I/O port bit PC3. If INT1 = 1 the pin is the active-low 8051 INT1 interrupt input signal, which is either edge triggered (IT1=1) or level triggered (IT1=0). Multiplexed pin whose function is selected by the “T0” bit of th

14、e PORTCCFG register. If T0=0, the pin is the bi-directional I/O port bit PC4. If T0 = 1 the pin is the active-high T0 signal for 8051 Timer 0, which provides the input to Timer 0 when C/T0 is 1. When C/T0 is 0, Timer0 does not use this bit. Multiplexed pin whose function is selected by the “T1” bit

15、of the PORTCCFG register. If T1=0, the pin is the bi-directional I/O port bit PC5. If T1 = 1 the pin is the active-high T1 signal from 8051 Timer 1, which provides the input to Timer 1 when C/T1 is 1. When C/T0 is 0, Timer1 does not use this bit. Multiplexed pin whose function is selected by the “WR

16、” bit of the PORTCCFG register. If WR=0, the pin is the bi-directional I/O port bit PC6. If WR = 1 the pin is the active-low write signal for external memory. Multiplexed pin whose function is selected by the “RD” bit of the PORTCCFG register. If RD=0, the pin is the bi-directional I/O port bit PC7.

17、 If RD = 1 the pin is the active-low read signal for external memory. 3.3V power source Ground -8- Pin No.Pin NameI/ODescription 24 31 32 33 34 35 36 37 38 39 40 41 42 43 44 D0 D7 BKPT VCC GND SDA SCL _ WAKEUP GND _ PA4/FWR _ PA5/FRD USBD- USBD+ _ DISCON VCC 8051 data bus. This bi-directiona bus is

18、high-impedance when inactive, input for bus reads, and output for bus writes. The data bus is also used to transfer data directly to and from internal EZ- _ USB FIFOS under control of the FRD and FWR strobes. D0-D7 are active only for external bus accesses, and are driven low in suspend. Breakpoint.

19、 This pin goes active (high) when the 8051 address bus matches the BPADDRH/L registers and breakpoints are enebled in the USBBAV register (BPEN=1). If the BPPULSE bit in the USBBAV register is HI, this signal pulses high for eight 24 MHz clocks. If the BPPULSE bit is LO, the signal remains high unti

20、l the 8051 clears the BREAK bit (by writing 1 to it) in the USBBAV register. 3.3V power source Ground I2C data. Connect to VCC with a 2.2 k resistor. I2C clock. Connect to VCC with a 2.2 k resistor. USBwakeup. If the 8051is unsuspend, a high to low edge on this pin starts up the oscillator and inter

21、rupts the 8051to allow it to exit the suspend mode. Ground Multiplexed pin whose function is selected by the “FWR” (Fast Write) bit of the PORTACFG register. If FWR=0, the pin is the bi-directional I/O port pin PA4. If FWR = 1 the pin is the write strobe for an external FIFO. Multiplexed pin whose f

22、unction is selected by the “FRD” (Fast Read) bit of the PORTACFG register. If FRD=0, the pin is the bi-directional I/O port pin PA5. If FRD = 1 the pin is the read strobe for an external FIFO. USB D - signal. Connect to the USB D - signal. USB D+ signal. Connect to the USB D + signal. Disconnect. Th

23、is signal drvives low when the 8051 sets the DISCON bit HI (USBCS3). When _ the DISCON bit is LO, the DISCON pin either drivers high or floats, depending on the state of the DISCOE bit (USBCS2). 3.3V power source I/O O O O I I/O I/O I/O I/O O I IC DESCRIPTION -1/1 (AN2136SC) -2/2 -9- MECHANICAL MAIN
