'Direct replacement for 16F84'

Hello comrads,

I was wondering if any of you could quickly answer a question for me; is there a
direct replacement for the 16F84? Excluding the EEPROM of course. From what I k
now the 16C54 and the 16C56 look promising. Am I wrong? Thanks in advance!

BEST Regards,
Steven

You can also check out the 16C61

The 16C54 and 56 are baseline devices, with a different instruction set to the
16F84.

The only other devices that have the same ROM/RAM configuration are the 16CR84,
which is only a masked device, I believe, and the 16C711. The 16C711 should
be fine, but you will need to disable the analog inputs.

It really depends on what you need - there are plenty of 18 pin chips, but they
have differing ROM/RAM sizes. If you can get away with less RAM or ROM, then oth
er
chips become possibilities.

Regards, Clyde

We use the 16c61, 16c711, 16c621, 16c622.  The last 2 parts have hardware
comparitors that you have to disable but have MUCH more RAM and code space
than an '84.  They are also cheaper.

The 16c5x parts are cheaper still but differ significantly.  You may have to
re-write some or all of your code work with them.

I guess you need the 16C556; it should be strictly compatible excluding
EEPROM, but has more RAM ;-)
In my country, the OTP version is only slightly cheaper than the F84 so I
would hesitate to replace (F84 is fine. I plan in all my applications with
F84 the ISP connector so I don't need to remove the IC when reprogram
[even not to dispose it as with OTP] ).
