WiZ232-A

Multifunctional Serial Interface IC

Technical Specifications

Serial Interface:

High speed serial port interface from 9600 to 230400 baud.

Serial Port Connection:

Three wire connection (Rx,Tx,GND)

Digital Lines

29 digital I/O arranged into three 8 bit general purpose ports (PA, PB, PC) and a 5 bit I/O port (PD). Each pin individually configurable as input or output. SPI port (PS) also available.

A/D Sampling rate:

 20 to 2,500 samples/sec.

PWM

Pulse rate from 15 Hz to 15 kHz with variable duty cycle. 24 bit output pulse counter up to 16 million.

Resistance:

500 Ohms to 10 MOhms

Capacitance:

100pF to 10µF

Period

Measurement of period from 65µS to 100mS. Minimum signal frequency 10 Hz, maximum 15 KHz. On-board pulse clipper allows use with AC signals from 500 mV rms to 5 V rms.

Stepper Control

Step speeds from 16 steps/sec to 8,500 steps/sec. Linear acceleration and deceleration between 0 to 255 steps/sec2. 24 bit position/stepping register. 4 output signals (pulse, direction, pause, trigger) for full (biphasic and monophasic) and half step modes. Steps to go feature between 1 to 8 million steps.
