In my project i want to interface a GSM modem and 24c02C i.e EEPROM (I2C based)to microcontroller. so now i am not understanding whether can i use same Rx-Tx pins to interface microcontroller (89s52) to EEPROM and GSM modem as well?? if not then is there any other microcontroller of AT89cxx/AT89sxx family with 2 serial ports? and which will support embedded c and assembly too!
Don't use the word "serial ports" like that.
I2C is a serial interface. But a completely different type of serial interface than the UART you would use for interfacing with the GSM modem.
There are lots of chips that have both UART and I2C in hardware. You can implement a I2C master in software quite easily too.
What 8051 processor will not support "embedded c" or assembly?
No i didn't mean that.. They do!
I came across 89C51RE2. this microcontroller has 2 UARTs n it belongs to 8051 family too!
What you think about this microcontroller? Is it okay?
Is/are there any other microcontrollers which will satisfy my basic needs i.e.
1) 2 UART's 2) 8051 family
I want your opinion. Please recommend me.. I searched on "Parametric search" available on Keil.com..
try the paramedic search at nxp
okay! thank you:)
