Replacement EEPROM

[Jeffrey D Angus]

The TI TBP18SA030 is a 16 pin fusible link PROM.
32 X 8 bits.

Anybody got some suggestions on what I can use for a replacement?
The SN74S188 is supposed to be the same, but that doesn't solve
my problem.

I'm looking for something along the lines of 27C64 or such.
I don't mind making up a 16 -> 28 pin adapter.

Thanks
Jeff

it looks like still make it in extended temp rage in a ceramic case as
JBP18S030MJ. I wonder who still uses these or what they're fixing
with them.

Make me rich and I'll send you the official bipolar PROM bag phone
programmer. Are you programming an MCX-90/100? There's also a
Standard low-band radio I have buried somewhere that uses this bipolar
PROM. You might ask on the Batlabs forum.

Well, just about any PAL with five inputs and eight outputs...

It's for a onesie? Maybe 28F64 would be easier than 27C64 to
program... neither is going to be as fast as the TBP18SA030
(about 30 ns, I think).

 

The Control Signal Corporation (CSC) of Denver, CO used this PROM (U1) in their model CWID-50B and -51B
Automatic Station Identifiers with FCC licensed Land Mobile or Amateur Radio Repeaters.
The PROM held the Morse Code (CW) message -- typically FCC license callsign.

The original 16-pin TTL PROM (32 x 8) -- TBP18SA030 -- is obsolete (no longer production) and the 1970s programmers are rare to find.
You can DIY Build an adapter to allow the usage of the more readily available 27Cxxx / 28Cxxx series EPROMS.
The CSC CWID-50B manual walks you through what each bit on the PROM is used for.
