I have need of a single chip that let me to measure time (hours and
minutes in 24hh format), temperature (in °C) and alternatively
display it, to a 4-LED display.
Which IC do you suggest to use?
Thanks in advance

Don't know of a singe IC, but very easy to do with a BasicStamp
uController, a clock(PCF8583) & a temp sensor(DS1620).

some sort of microcontroller, there may be free source code out there on the
web.

use one with atleast 14 I/O pins if you can multiplex the display, you'll
need 30 or more if not.

What do they use in cheap clocks? It may be easier to go backward from
that than to build from scratch if he only wants one. Some clock chips
do support temperature, even if the clock it is in doesn't.
