PLEASE

I need the most suitable real time clock for my 8052 chip. I want it to have an easy interface, and NOT serial, but parallel.

I did not cope with RTC's before, so please, I need your help urgently. I also would like if it has everythign built in (crystal , batter).

I dont want to buy a microprocessor with built in RTC, I just want an external RTC, and I want it to be VERY compatible with the 8052.

Please, help.
Thanks
