M11 - Mezzanine Card with 16-bit TTL I/O Interface

The M11 mezzanine card is a TTL I/O M-Module with 16 lines (Ports A and B) that can be used separately as two ports with 8 bits each or together as a 16-bit port. Control of the I/O lines is via the four handshake lines. Depending on the operation mode, the four handshake lines generate an interlocked handshake, a pulsed handshake, interrupt inputs or simple inputs.

The M11 is based on the M-Module ANSI mezzanine standard. It can be used as an I/O extension in any type of bus system, i.e. CPCI, VME oron any type of stand-alone SBC. Appropriate M-Module carrier cards in 3U, 6U and other formats are available from duagon or other manufacturers.
