Rated for simple slave applications, it manages up to 32 I/O bytes and supports automatic baud-rate detection up to 12 Mbit/s, the top speed for PROFIBUS DP. The 0.35 W power draw at 5 VDC and the -40 to 75 °C operating range mean it fits into compact, passively-cooled slave nodes without a heatsink, even on a warm backplane. ## Physical package and integration constraints Housed in an 80-pin MQFP with a 4 cm² footprint, the LSPM 2 is a surface-mount ASIC that reflows onto the slave-node PCB — no socket, no separate firmware load (scope of firmware: not necessary). Supplied in tray-boxes of 330 pieces, this is a production-volume part; for prototype or repair quantities, confirm the BOM position count before committing. No official successor or pin-compatible cross-reference is listed — the part is the designated slave controller for this generation of SIMATIC S5/S7 DP nodes.","metaTitle":"Siemens 6ES7195-0BA21-0XA0 ASIC LSPM 2, PROFIBUS DP Slave","metaDescription":"Siemens 6ES7195-0BA21-0XA0 ASIC LSPM 2 for PROFIBUS DP slave applications.
