Powerful and Versatile Controller

The I-7188XA(D) is for industry applications and can be used to replace PC or PLC devices in harsh environments. The I-7188XA controller is designed for palm-size embedded systems that require high reliability, PC-compatibility, and compactness at a reasonable price.

The controllers can be integrated into an OEM product as a processor core component. By building your product around I-7188XA controller, you reduce the time from design to market introduction, cut development costs, minimize technical risks, and deliver a more reliable product.

Depending on the type of embedded firmware programs that are being developed, and which I/O Expansion Board, the I-7188XA(D) can be used as a single versatile controller.

I/O Expansion Bus and Expansion Board

The I-7188XA supports an I/O expansion bus.

The I/O expansion bus can be used to implement various I/O functions such as D/I, D/O, A/D, D/A, Timer/Counter, UART, flash memory, battery backup SRAM, AsicKey & other I/O functions. Nearly all kinds of I/O functions can be implemented by this bus. 

The integrated modular design of the expansion board allows a fast, easy, and flexible way of upgrading our controller's capability.
