1.4 Main Components
1 XYLINX-XC95144XL-
10TQG144C.
(M/B-U1)
It’s a 3.3V CPLD targeted for high-performance, low-voltage application in leading-
edge communications and computing system.
2 Motor Driver L6258EX.
(M/B-U5)
It’s a dual full bridge for motor control application realized in BCD technology, with
the capability of driver both winding of a bipolar stepper motor or bi-directional
control two DC motor.
3 RS232 Drv AX3232.
(M/B-U18)
It’s a device consists of two line driver, two receiver, and a dual change-pump circuit
with +-15kv ESD protection pin to pin.
