LSPM 2
LSPM 2 is a single-chip solution with 32 input/output bits. It processes all bus communication autonomously. An
additional microprocessor and firmware are not required. The compact MQFP casing with 80 pins makes it ideal for
applications with low space requirements.
FOCSI
This ASIC functions as an expansion to the existing PROFIBUS ASICs. The FOCSI module (Fiber Optic Controller
from Siemens) ensures proper electrical conditioning and transfer of the received/sent optical signal. To inject the signal
into a fiber-optic conductor, apart from FOCSI, the appropriate optical transmitter and receiver will be required. FOCSI
can be used with the PROFIBUS DP ASICs described above.
