5 / 29 page áç áç áç áç ST16C2450 REV. 4.0.0 2.97V TO 5.5V DUART 5 Pin type: I=Input, O=Output, IO= Input/output, OD=Output Open Drain. DSRB# 25 20 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# 21 16 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# 26 21 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. OP2B# 15 9 O Output Port 2 Channel B - The output state is defined by the user and through the software setting of MCR[3]. INTB is set to the active mode and OP2B# output to a logic 0 when MCR[3] is set to a logic 1. INTB is set to the three state mode and OP2B# to a logic 1 when MCR[3] is set to a logic 0. This output should not be used as a general output else it will disturb the INTB output functionality. If it is not used, leave it uncon- nected. ANCILLARY SIGNALS XTAL1 18 13 I Crystal or external clock input. XTAL2 19 14 O Crystal or buffered clock output. RESET 39 36 I Reset (active high) - A longer than 40 ns logic 1 pulse on this pin will reset the internal registers and all outputs. The UART transmitter out- put will be held at logic 1, the receiver input will be ignored and outputs are reset during reset period. VCC 44 42 Pwr 2.97V to 5.5V power supply. All inputs are 5V tolerant for devices with top marking of "A2 YYWW" and newer. GND 22 17 Pwr Power supply common, ground. N.C. 1, 12, 23, 34 6, 12, 18, 24, 25, 31, 37, 43 - No Connection. These pins are open, but typically, should be con- nected to GND for good design practice. Pin Description NAME 44-PLCC PIN # 48-TQFP PIN # TYPE DESCRIPTION |
