5 / 51 page  PRELIMINARY XR16V2752 5 REV. P1.0.0 HIGH PERFORMANCE DUART WITH 64-BYTE FIFO Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain. RTSB# 13 23 O UART channel B Request-to-Send (active low) or general purpose output. This port must be asserted prior to using auto RTS flow control, see EFR[6], MCR[1], FCTR[1:0], EMSR[5:4] and IER[6]. For auto RS485 half- duplex direction control, see FCTR[3] and EMSR[3]. CTSB# 17 28 I UART channel B Clear-to-Send (active low) or general purpose input. It can be used for auto CTS flow control, see EFR[7], and IER[7]. This input should be connected to VCC when not used. DTRB# - 27 O UART channel B Data-Terminal-Ready (active low) or general purpose output. If this pin is not used, leave it unconnected. DSRB# - 29 I UART channel B Data-Set-Ready (active low) or general purpose input. This input should be connected to VCC when not used. This input has no effect on the UART. CDB# - 30 I UART channel B Carrier-Detect (active low) or general purpose input. This input should be connected to VCC when not used. This input has no effect on the UART. RIB# - 31 I UART channel B Ring-Indicator (active low) or general purpose input. This input should be connected to VCC when not used. This input has no effect on the UART. MFB# - 19 O Multi-Function Output Channel B. This output pin can function as the OP2B#, BAUDOUTB#, or RXRDYB# pin. One of these output signal func- tions can be selected by the user programmable bits 1-2 of the Alternate Function Register (AFR). These signal functions are described as follows: 1) OP2B# - When OP2B# (active low) is selected, the MF# pin is LOW when MCR bit-3 is set HIGH (see MCR bit-3). MCR bit-3 defaults to a logic 0 condition after a reset or power-up. 2) BAUDOUTB# - When BAUDOUTB# function is selected, the 16X Baud rate clock output is available at this pin. 3) RXRDYB# - RXRDYB# (active low) is intended for monitoring DMA data transfers. See Table 2 for more details. ANCILLARY SIGNALS XTAL1 4 11 I Crystal or external clock input. Caution: this input is not 5V tolerant. XTAL2 5 13 O Crystal or buffered clock output. RESET 12 21 I Reset (active high) - A longer than 40 ns HIGH pulse on this pin will reset the internal registers and all outputs. The UART transmitter output will be held HIGH, the receiver input will be ignored and outputs are reset during reset period (see Table 16). VCC 26 44, 33 Pwr 2.25 to 3.6V power supply. All input pins, except XTAL1, are 5V tolerant. GND 20 22, 12 Pwr Power supply common, ground. NC 18, 19 - - No Connect. Pin Description NAME 32-QFN PIN # 44-PLCC PIN # TYPE DESCRIPTION |
