3 / 34 page 2010 Microchip Technology Inc. DS22228A-page 3 MCP2200 1.0 FUNCTIONAL DESCRIPTION The MCP2200 is a USB-to-UART serial converter which enables USB connectivity in applications that have a UART interface. The device reduces external components by integrating the USB termination resistors. The MCP2200 also has 256 bytes of integrated user EEPROM. The MCP2200 has eight general purpose input/output pins. Four pins have alternate functions to indicate USB and communication status. See Table 1-1 and Section 1.6 “GPIO Module” for details about the pin functions. TABLE 1-1: PINOUT DESCRIPTION Pin Name SSOP, SOIC QFN Pin Type Standard Function Alternate Function GP0/SSPND 16 13 I/O General purpose I/O USB suspend status pin (refer to Section 1.6.1.1 “SSPND Pin Function” ) GP1/USBCFG 15 12 I/O General purpose I/O USB configuration status pin (refer to Section 1.6.1.2 “USB- CFG Pin Function” ) GP2 14 11 I/O General purpose I/O GP3 9 6 I/O General purpose I/O GP4 8 5 I/O General purpose I/O GP5 7 4 I/O General purpose I/O GP6/RxLED 6 3 I/O General purpose I/O USB receive activity LED output (refer to Section 1.6.1.3 “RxLED Pin Function (IN Mes- sage)” ) GP7/TxLED 5 2 I/O General purpose I/O USB transmit activity LED output (refer to Section 1.6.1.4 “TxLED Pin Function (OUT Message)” ) RST 4 1 I Reset input must be externally biased CTS 13 10 I Hardware flow control “Clear to Send” input signal RX 12 9 I USART RX input RTS 11 8 O Hardware flow control “Request to Send” output signal TX 10 7 O USART TX output VDD 118 P Power VSS 20 17 P Ground OSC1 2 19 I Oscillator input OSC2 3 20 O Oscillator output D+ 19 16 I/O USB D+ D- 18 15 I/O USB D- VUSB 17 14 P USB power pin (internally connected to 3.3V). Should be locally bypassed with a high quality ceramic capacitor. EP — 21 — Exposed Thermal Pad (EP). Do not electrically connect, or connect to VSS. |
