GENERAL DESCRIPTION
The Z08617 KEYBOARD CONTROLLER is a member of the Z8® single-chip microCONTROLLER family with 4 Kbytes of ROM. The device is housed in a 40-pin DIP package, and is manufactured in NMOS technology. The Z08617 microCONTROLLER offers fast execution, efficient use of memory, sophisticated interrupt, input/output bit manipulation capabilities, and easy hardware/soft ware system expansion along with low cost and low power consumption.
The Z08617 architecture is characterized by a flexible I/O scheme, an efficient register, I/O, and a number of ancillary features that are useful in many industrial and advanced scientific applications.
For applications which demand powerful I/O capabilities, the Z08617 provides 32 pins dedicated to input and output. These lines are grouped into four ports, each port consists of 8 lines, and are configurable under software control to provide timing, status signals, and serial or parallel I/O ports.
The Z08617 offers low EMI emission which is achieved by means of several modifications in the output drivers and clock circuitry of the device.
There are two basic address spaces which are available to support this wide range of configurations: Program Memory and 124 General-Purpose Registers.

Description : CMOS SINGLE-COMPONENT 8-BIT KEYBOARD CONTROLLER

CMOS SINGLE-COMPONENT 8-BIT KEYBOARD CONTROLLER

Part Name(s) : KBD42W11
SMSC
SMSC -> Microchip
Description : KEYBOARD CONTROLLER

GENERAL DESCRIPTION
The KBD42W11 KEYBOARD CONTROLLER is programmed to support the IBM® compatible personal computer KEYBOARD serial interface. The KEYBOARD CONTROLLER receives serial data from the KEYBOARD, checks the parity of the data, translates the scan code, and presents the data to the system as a byte of data in its output buffer. The CONTROLLER will interrupt the system when data is placed in its output buffer. The byte of data will be sent to the KEYBOARD serially with an odd parity bit automatically inserted. The KEYBOARD is required to acknowledge all data transmissions. No transmission should be sent to the KEYBOARD until acknowledgment is received for the previous byte sent.

FEATURES
• Supports IBM PC and Compatible System Designs
• Runs Much Faster Than Traditional KEYBOARD CONTROLLERs
• Host interface Compatible with Traditional KEYBOARD CONTROLLER
• 6 MHz – 12 MHz Operating Frequency
• Communicates with KEYBOARD Directly
• High-reliability CMOS Technology
• 40 Pin DIP and 44 Pin PLCC Package
