I need a replacement for Philips 87C550 device that has become obsolete.

My aplication specifications:

- code size : 4 KBytes
- RAM size : 128 Bytes
- Timer used : T0 - 8 bit autoreload
- AD converter: 1 - 8 bit used
- WDOG timer : used
- CPU speed : 16 MHz standard (CLK/12)

If you know a direct replacement or similar and cost effective please let me know.

Thank you! Franc
