How to Drive 272 LEDs With AT89C51 or DS89C410 for Digital Clock Project?

hello guys i want to make a digital clock using RTC in which each segment contains 66 leds and total 4 segments and extra 8 leds for dots ..... i wanna do this with at89c51 or ds89c410 but i dont know that how to interface these bulk of leds to single board and to glow them at a time ....... how to maintain current and voltage reqirements of all leds ?? since uptill now i had interfaced only 2 leds to 8051 ....so please help me tel me all alternatives to do that !! plzzzz suggest any resourses any idea ,,,,

Check the TM1638 chip. Got it working on a row of 8 7-segment display and can put on/off each segment, point, and even dim the segments in 8 steps.
You can daisy-chain these chips, up to 6 pieces.

An example, in Dutch on www.pa0kn.nl

but the resource you have suggested to deal work with TM1638 chip,,,,,,, from where i can find every thing about this chip,??

Lots of datasheets of the TM1638 but they are all in Chinese. But I have found an English datasheet for the TM1628 which has the same command-structure.

With one TM1638 you can drive 64 LEDs and even dim them. You can daisy chain 6 of them.

can you send me that datasheet in english;;;;;; plz.. email: dharmik33(_at_)gmail.com
thanks
