CMOS IC
LC8953
General-Purpose 68000 MPU
Peripheral Interface IC
PUPPET (Programmable Universal Peripheral/Port Expansion uniT)
Overview
There are many application systems using the 68000 chip
as their MPU (Main Processing Unit). It is common to them
that designing the peripheral circuits such as address de-
coders, interrupt controllers, serial interface and DMA (Di-
rect Memory Access) has become a time-consuming task.
As a result, each of the application systems requires a larger
board size, which makes it very expensive.
In addition, 68000 family peripherals are highly advanced
functional ICs. The application system designer finds it dif-
ficult to use them in small- and medium-sized application
products in terms of cost as well as functional complexity.
The LC8953 (Programmable Universal Peripheral/Port
Expansion uniT) has optimized on-chip control circuits
enabling the 68000 MPU to control the LC8951 (RCHIP)
and LC8955. Use of the optimized control circuits allows
the user to easily build up CD-ROM and CD-I systems
which offer excellent performance in terms of space and
cost.
