The W83C42 keyboard controller is programmed to support the IBM compatible personal computer keyboard serial interface. It enables popular programs such as AutoCAD, Microsoft Windoes 3.1, NOVELL, and other programs to run much faster. Also, it is available in 40-pin DIP package.
Here are some features about it: (1)supports IBM PC/AT 386DX/SX and 486DX/SX system designs; (2)runs much faster than traditional keyboard controllers; (3)host interface compatible wih traditional keyboard controller; (4)communicates with keyboard directly; (5)high-reliablility CMOS technology.
What comes next is about its absolute maximum ratings: (1)ambient operating temperature: 0 to 85 ; (2)storage temperature: -65 to 150 ; (3)supply voltage to ground potential: -0.3 V to 7.0 V; (4)applied input/output voltage: -0.3 V to 7.0 V; (5)power dissipation: 50 mW. Then is the electrical characteristics(TA=0 to 70 , VDD=5 V ±5%): (1)power supply: 4.75 V min, 5.0 V typ and 5.25 V max; (2)high level voltage for TTL min.I/P: 2.0 V min and VDD max; (3)low level voltage for TTL max.I/P: -0.3 V min and 0.8 V max; (4)I/P leakage current: -10 A min and 10 A max; (5)O/P sink current: 4 mA min; (6)O/P load capacity: 15 pF min and 50 pF max.
The W83C43 is a keyboard controller designed to provide the functions needed to interface a CPU to a keyboard or to a PS/2 mouse. The W83C43 can be used with IBM®-compatible personal computers or PS/2-based systems. The controller receives serial data from the keyboard or PS/2 mouse, checks the parity of the data, and presents the data to the system as a byte of data in its output buffer. The controller will interrupt the system when data are placed in its output buffer. The keyboard and PS/2 mouse are required to acknowledge all data transmissions. No transmission should be sent to the keyboard or PS/2 mouse until acknowledge is received for the previous byte sent.
This fast keyboard controller can improve the performance of IBM PC/AT® 386™ DX/SX and 486™ DX/SX machines and their compatibles. Hardwire methodology is used in this controller instead of software implementation, as in the traditional 8042 keyboard BIOS. With full hardware implementation, this enables the keyboard controller to respond instantly to all commands sent from the keyboard and PS/2 mouse to the CPU BIOS.
The keyboard controller enables popular programs such as AutoCAD®, Microsoft® Windows™3.1, NOVELL®, and other programs to run much faster.
