overwhelmed by chips,

[PICMAN]

i need drop in replacement for pic16f84a,
with internal 20 mhz res, i need it to have same pinout as pic16f84a, in dip , same or more memory at low cost

[PICMAN]

looks like my choice of :
16f88
16f819

[PICMAN]

any sugestions on preferably an 18 pin led driver, with higher curent restraints thn 16f84? perhaps to run a lil transistor matrix of 16f84 or f88 might be easier eh

[Melanie]

Also try 16F628A.

[PICMAN]

ty will order a few of those as well

[kenpo]

just make sure to get the 20mhz version of the 16f628.

No panic ...

Our guy was looking for 20 Mhz INTERNAL Oscillators ... on other lists too !!!

There's no such thing as a 20MHz INTERNAL OSCILLATOR. You will need an external xtal or resonator for that speed.

yeh i was confused, kept reading spec sheets, and thinking there WAS 20 mhz internal, only to find out it doesnt exzist, that what i was reading to say internal 20 mhz, was infact 8 mhz, at best, question was posted on *2* boards, as i posted one, waited got no answer and had an order going to ship, and needed to know asap, i dont quite understand acetronics post here, but melanie ty vm, i dont kinow how i over looked where it said internal 8 mhz up to 20 mhz ext, but i woulda been quite unhappy if i had spent all my part $ on chips i thought iliminated xtrnl xtals, landed up geting only 6 chips, and 8 resanators, AND was able to identify 4 8 and 20 mhz chips threw various tips on both boards, both offerd invaluable info, to aid me in making my first chip / parts order, fyi the problem wasnt the cost of chips but rather shiping, so it came down to one chance to get it right, and i relized i messed up after i made the original order, leaving me 8 hrs to rectify it b4 it shiped,
thnx again for all the usefull replies, every thing worked out because of it
