Cheapest 8-bit micro in SOIC case

It should have internal oscillator, 8-bit timer and external interrupt
possibility and at least 1kb of code memory. 32 bytes of RAM are enough.
ROM parts are not an option (FLASH, OTP, EEROM are OK).
Quantity is 50k+

Any ideas?

attiny11 probably cheapest - not sure if it has int osc.
Also look at PIC10F series.

There must be something in the Philips LPC900 series that meets the bill.

The minimum number of I/O required is an important and unstated
parameter.

I forgot that - 6 I/O pins (SOIC8 case).

With all the micros available today. ( mot, micrchip, TI, atmel )

Why are you asking for someone else to do you the job your paid for ??

Each micro has its best points and its not so best points.

Either give more information or do your own homework.

What's the point of a news group if it isn't to exchange information?

The usual suspects, include :
  Atmel (esp Tiny11),
  Fairchild ACE family,
  Gencore { OTP So8, but probably over-resourced)
  Microchip (down to SOT23-6),
  Motorola,
  Philips (SO8 & also smaller MLF10),
  STm ( IIRC )
  Zilog

  Price depends on what part of the profit/loss cycle the
suppliers are on....
