Description

The PIA-3312 forms the durable, performand core of many embedded control applications. The module is highly integrated due to the INTEL 386EX system that combines chipset and CPU. This combination results in better performance, a longer life and less power consumption. The module supports the DOS operating system.

With the integration of chipset and CPU, space is left for an onboard Flash/ROM disk and two COM ports that support either RS-232 or RS-485.
