5 / 52 page  2001-2013 Microchip Technology Inc. Preliminary DS21690B-page 5 MCP2155 TABLE 1-2: PIN DESCRIPTION Pin Name Pin Number Pin Type Buffer Type Description PDIP SOIC SSOP BAUD0 1 1 1 I ST BAUD1:BAUD0 specify the baud rate of the device. For more information see Section 2.5.1. TXIR 2 2 2 O — Asynchronous transmit to Infrared transceiver. RXIR 3 3 3 I ST Asynchronous receive from Infrared transceiver. RESET 4 4 4 I ST Resets the device. VSS 5 5 5, 6 — P Ground reference for logic and I/O pins. EN 6 6 7 I TTL Device enable. 1 = Device is enabled 0 = Device is disabled (low power) TX 7 7 8 I TTL Asynchronous receive; from Host Controller UART. RX 8 8 9 O — Asynchronous transmit; to Host Controller UART. RI 9 9 10 I TTL Ring Indicator. The state of this bit is communicated to the IrDA Primary Device. 1 = No Ring Indicate Present 0 = Ring Indicate Present DSR 10 10 11 O — Data Set Ready. Indicates that the MCP2155 has established a valid link with a Primary Device. This signal is locally emulated and not related to the DTR bit of the IrDA Primary Device. 1 = An IR link has not been established (No IR Link) 0 = An IR link has been established (IR Link) DTR 11 11 12 I TTL Data Terminal Ready. Indicates that the Embedded device con- nected to the MCP2155 is ready for IR data. The state of this bit is communicated to the IrDA Primary Device, via the irDA bit car- ried by IrCOMM. 1 = Embedded device not ready 0 = Embedded device ready At device power-up, this signal is used with RTS to enter device ID programming. 1= Enter Device ID programming mode (if RTS is cleared) 0= Do not enter Device ID programming mode CTS 12 12 13 O — Clear to Send. Indicates that the MCP2155 is ready to receive data form the Host Controller. This signal is locally emulated and not related to the CTS/RTS bit of the IrDA Primary Device. 1 = Host Controller should not send data 0 = Host Controller may send data RTS 13 13 14 I TTL Request to Send. Indicates that the Host Controller is ready to receive data from the MCP2155. This signal is locally emulated and not related to the CTS/RTS bit of the IrDA Primary Device. 1 = Host Controller not ready to receive data 0 = Host Controller ready to receive data At device power-up, this signal is used with CTS to enter device ID programming. 1= Do not enter Device ID programming mode 0= Enter Device ID programming mode (if DTR is set) VDD 14 14 15, 16 — P Positive supply for logic and I/O pins. OSC2 15 15 17 O — Oscillator crystal output. OSC1/CLKIN 16 16 18 I CMOS Oscillator crystal input/external clock source input. Legend: TTL = TTL compatible input ST = Schmitt Trigger input with CMOS levels I = Input O = Output P = Power CMOS = CMOS compatible input 21690B.book Page 5 Thursday, January 10, 2013 1:06 PM |
