EV80C196KB Microcontroller Evaluation Board User's Manual
HARDWARE OVERVIEW OF THE EV80C196KB BOARD
The EV80C196KB Microcontroller Evaluation board is delivered with an 8OC196KB,
8 K-words and 8 K-bytes of user code/data memory, a UART for host communica-
tions and analog-input filtering with a precision voltage reference. Also included is
programmable chip-select, bus-width and wait-state-counter logic which allows you
to custom tailor the board to look like your own system. The board's physical dimen-
sions are 6 l/2" x 7 3/4" with an overall height of 3W. There are six main sections
to the EV80C196KB board: Processor, Memory, Host Interface, Digital I/O, Analog
Inputs and Decoding.

Processor
The Intel@)80C196KB is a 16-bit embedded microcontroller. Being a member of the
MCW-96 family, the 8OC196KB uses the same powerful instruction set and the
same architecture as the existing MCS-96 products. The 8OC196KB is an enhanced
CMOS version of the 8097BH. Its enhancements include up/down and capture
modes on Timer2, multiplyin
nearly twice as fast, Hold/Ho d Acknowledge logic, and power-down and idle modes
9
speeds almost 3 times as fast, overall execution
to save power. For more information, please refer to the 1989 "16-Bit Embedded
Controller Handbook," Intel Corporation order number 270646-001 and the
8OC196KB Datasheet order number 270634-001.
Memory
There are five 28-pin memory sockets provided on the EV80C196KB board: Ul , U6,
U8, U13 and U14. The sockets are designed to support byte-wide, JEDEC-pinout,
memory devices of various types and sizes, i.e. 8K x 8 SRAM or 16K x 8 EPROM.
Ul and U8, U6 and U13 are connected as two 16-bit memory banks and U14 is
connected as an 8-bit memory bank.
