    \$\begingroup\$ Which component are you asking about? or do you mean the whole board? If the whole board, there's a big hint on the label. Just identify the serial pins, hook up a terminal, and ask it. \$\endgroup\$ May 30, 2016 at 13:18

It's an older type of small microcomputer with program stored in battery-backed RAM. It has a serial interface and an 8-bit 8051-core processor.

Not very amazing these days. It has a static 32K x 8 RAM. You can probably talk to it via that 2x5 port on the lower right-hand side by the MAX232. Probably powered via the grey terminal block.
