I'm currently using a 16F84 on my application, but
need more ram and more data EEPROM space. I'm new to the
microchip controller line. I can't seem to find an upward
path to more RAM and more EEPROM space without having my
pin count go through the roof.
Anybody have a suggestion what chip I should look at?
I recommend 16CE625. Has 128 byte EEPROM, and more data EEPROM.
Unfortunately, the EEPROM is an on-board I2C one but I have already used
it.
I hope this helps.

I guess I'm off in the weeds trying to make the
93AA86 (serial eeprom) disappear from the circuit.
my code is basicly 16 identical processes, each interpreting
a simple byte stream (don't panic, they don't have to
go very fast).
To avoid re-engineering the whole thing, I think
I'll leave the 95AA86 and move to one of the 16C???
series.
Thanks everybody for the help.

The question is, how much more? There's the 16F628 coming, but not here yet,
with 2k program Flash, 128 bytes data EEPROM and 228 bytes RAM. Bonus is
an on-chip UART and 3 timers vs. the F84's one.

I gave up on getting the data EEPROM onto the chip, and
went to an external serial EEPROM (93LC86 if you're interested)
