Sanyo LC8953 Specifications
Ordering number:ENN3411B
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 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 smalland 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.
