Yes it might be. The only differences are the pin 1 marking and the die cap size

It's an HP designed chip. The top number, 1820-2884, is an HP replacement number. The second number, 1AA6-6104, is an actual HP part number. I have no idea what is it, but I don't think it's from 290x family.

The article mentions a 1AA6-6004 but no (1AA6-6104) or did I miss something. |

| Quote: | 8-22. PHI CHIP U20. The acronym "PHI" stands for Processor to HP-IB
Interface. This chip is a self-contained microcontroller that adapts a wide
variety of microprocessor chips to the HP-IB bus. Some of the general
characteristics of the PHI chip are: (1) data is sent at the rate of the
slowest listener (up to one megabyte per second), (2) data transfer is
asynchronous, ajid (3) more than one peripheral device can accept data
simultaneously. To ensure that the transfer of data is accomplished in am
orderly manner, a set of three "handshake" signals are used: Data Valid (DAV) ,
Ready for Data (RFD), and Data Accepted (DAC). These three handshake signals
ensure: (1) that each listener is ready to accept data, (2) that the data on
the data bus in valid, eind (3) that the data has been accepted by all
listeners. |
