Sanyo LC8953 Specifications
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

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 decoders, interrupt controllers, serial interface and DMA (Direct 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 difficult 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
