5. The OP6800 also has one RS 485 serial channel and one CMOS serial channel The CMOS serial channel serves as the programming port All four serial ports operate in an asynchronous mode An asynchronous port can handle 7 or 8 data bits A 9th bit address scheme where an additional bit is sent to mark the first byte of a message is also supported Serial Port A the CMOS programming port can be oper ated alternately in the clocked serial mode In this mode a clock line synchronously clocks the data in or out Either of the two communicating devices can supply the clock The OP6800 boards typically use all four ports in the asynchronous serial mode Serial Ports B and C are used for RS 232 communication and Serial Port D is used for RS 485 commu nication The OP6800 uses an 11 0592 MHz crystal which is doubled to 22 1184 MHz At this frequency the OP6800 supports standard asynchronous baud rates up to a maximum of 230 400 bps 3 3 1 RS 232 The OP6800 RS 232 serial communication is supported by an RS 232 transceiver This transceiver provides the voltage output slew rate and input voltage immunity required to meet the RS 232 serial communication protocol Basically the chip translates the Rabbit 2000 s CMOS TTL signals to RS 232 signal levels Note that the polarity is reversed by an RS 232 circuit so that a 5 V input becomes approximately 10 V and O V is output as 10 V The RS 232 transceiver also provides the proper lin

R37 22 kQ Figure B 1 OP6800 Backup Battery Circuit The battery backup circuit serves three purposes e It reduces the battery voltage to the SRAM and to the real time clock thereby limiting the current consumed by the real time clock and lengthening the battery life e Jt ensures that current can flow only out of the battery to prevent charging the battery e A voltage VOSC is supplied to U6 which keeps the 32 768 kHz oscillator working when the voltage begins to drop VRAM and Vcc are nearly equal lt 100 mV typically 10 mV when power is supplied to the OP6800 60 MiniCom OP6800 B 2 2 Power to VRAM Switch The VRAM switch on the OP6800 module shown in Figure B 1 allows the battery backup to provide power when the external power goes off The switch provides an isola tion between Vcc and the battery when Vcc goes low This prevents the Vcc line from draining the battery VCC VRAM R33 A 00 Q5 FDV302P E 10 kQ R17 Q2 RESET Bik MMBT3904 Figure B 1 VRAM Switch Field effect transistor Q5 is needed to provide a very small voltage drop between Vcc and VRAM lt 100 mV typically 10 mV so that the board components powered by Vcc will not have a significantly different voltage than VRAM When the OP6800 is not in reset the RESET line will be high This turns on Q2 causing its collector to go low This turns on Q5 allowing VRAM to nearly equal Vcc
