10 / 108 page  CP2200/1 10 Rev. 1.0 5. Pinout and Package Definitions Table 4. CP2200/1 Pin Definitions Name Pin Numbers Type Description 48-pin 28-pin AV+ 5 3 Power In 3.1–3.6 V Analog Power Supply Voltage Input. AGND 4 2 Analog Ground VDD1 13 8 Power In 3.1–3.6 V Digital Power Supply Voltage Input. DGND1 14 9 Digital Ground VDD2 30 19 Power In 3.1–3.6 V Digital Power Supply Voltage Input. DGND2 31 20 Digital Ground RST 15 10 D I/O Device Reset. Open-drain output of internal POR and VDD monitor. An external source can initiate a system reset by driving this pin low for at least 15 µs. LINK 3* — D Out Link LED. Push-pull output driven high when valid 10BASE-T link pulses are detected (Link Good) and driven low when valid 10BASE-T link pulses are not detected (Link Fail). ACT 2* — D Out Activity LED. Push-pull output driven high for 50 ms when any packet is transmitted or received and driven low all other times. LA — 1* D Out Link or Activity LED. Push-pull output driven high when valid link pulses are detected (Link Good) and driven low otherwise (Link Fail). The output is toggled for each packet transmitted or received, then returns to its original state after 50 ms. XTAL1 46 28 A In Crystal Input. This pin is the return for the external oscillator driver. This pin can be overdriven by an external CMOS clock. XTAL2 45* 27* A Out Crystal Output. This pin is the excitation driver for a quartz crystal. TX+ 9 6 A Out 10BASE-T Transmit, Differential Output (Positive). TX– 10 7 A Out 10BASE-T Transmit, Differential Output (Negative). RX+ 7 5 A In 10BASE-T Receive, Differential Input (Positive). RX– 6 4 A In 10BASE-T Receive, Differential Input (Negative). MOTEN 43 26 D In Motorola Bus Format Enable. This pin should be tied directly to VDD for Motorola bus format or directly to GND for Intel bus format. MUXEN 44 — D In Multiplexed Bus Enable. This pin should be tied directly to VDD for multiplexed bus mode or directly to GND for non-multiplexed bus mode. INT 42 25 D Out Interrupt Service Request. This pin provides notification to the host. *Note: Pins can be left unconnected when not used. |
