» Introduction
The I-7188 series controllers are 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-7188 series controller, you reduce the time from design to market introduction, cut development costs,
minimize technical risks, and deliver a more reliable product.
I-7188 is a first generation product while the I-7188XA, I-7188XB and I-7188XC are all secondgeneration products.
The major differences are communication ports, digital I/O port, and user defined I/O pins. Except I-7188, all I-7188XA/XB/XC support an I/O expansion bus.
» I/O Expansion Bus and Expansion Board
The I-7188XA, I-7188XB and I-7188XC support 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. Our I/O expansion boards offer features in addition to those provided by the I-7188XA/XB/XC embedded controller.
Expansion board can increase controller’s I/Os and memory storage capabilities. The integrated
modular design of the expansion board allows a fast, easy, and flexible way of
upgrading our controller’s capability. Each I/O expanison bus supports one
expansion board.
