Lines: 22 Greetings... Has anyone on the net had any experience with a single-chip microcontroller that has approximately the specifications shown below? Here's what I need: - 8 bit CMOS, and with a clock frequency of ~ 3-5 MHz - 2 input bits, 4 output bits ( slightly more OK ) - a small amount of onboard RAM (< 32 bytes) - Pin count of <=24 (this is a must) - must have a version with EPROM or EEPROM (for prototyping) - must have a version with one-time user programmability (for low-volume production) - low cost (of course!) I seem to recall an ad for a few years back about a General Instrument microcontroller (PIC or something) that had only 18 pins, but I don't know if it is fast enough. Len -- ... LEONARD T.
