Controlling 2 serial ports from PC with 8051

[ginnyykw]

Hi, I would like to control 2 serial ports from PC with 8051.

Which MCU can I choose to achieve it?

Thx~

u can check Cygnal Microcontrollers series

having same 8051 Architecture with enhanced Peripherals

2 serial ports atmel

Use ATmega128 with 2 hardware serial ports or any AVR with 1 hardware and 1 software serial port.

2 serial ports 8051

Thanks for your advice.

However, I would like to use 8051 to achieve it.

Is there any suggestions?

how to have two serial ports on 8051

Hi,
So you want an 8051 MCU with 2 UART's. There are many types of this sort of MCU's. You can look e.g. on this DS83C520 **broken link removed**. It has 2 lines Rx and Tx.
If you would like more help ask

microcontroller that has 2 serial ports

DALLAS MICRO DS89C430 ALSO HAS 2 PORTS, FLASH MEMORY AND SERIAL BOOTSTRAP LOADER
MANY OTHER 8051 SERIES

There are 2 devices from NXP, the LPC952 and the LPC954 that come with 2 UARTs.
THe core is a 2-cycle 8051 core and the internal oscillator is good enough for your UARTs, no need for an external oscillator.

8051 using 2 serial port

Cygnal 8051 sure is the best 8051 except the price and sample. They do have good silicon design, references and support.

2 serial ports microcontroller

what about using a simple tristate buffer than going for microcontroller with two Uarts. 74244 is enough for this, but there should be one master controller (either pc or uc) to do this

microcontroller with 2 serial port

Hi,

Can anyone elaborate more one adding tri-state buffer on interfacing 2 serial ports?

Thanks in advanced~~
