Description : Video Decoder and SYSTEM CONTROLLER (with JTAG) View

INTRODUCTION
The Video Decoder and SYSTEM CONTROLLER with JTAG (VDSC/JTAG) is a CMOS device integrating a 680X0 family SYSTEM CONTROLLER and video graphics decoder, see Figure 1–1 below.
The MCD212 is a programmable, multi–scan video device that can function as either a master or a slave. It is functionally equivalent to the MCD211 with the addition of JTAG testing. The MCD212 is a drop–in replacement for the MCD211 if the JTAG functionality is not required. It can directly drive up to 5M bytes1 of memory and provides chip–select signals for SYSTEM ROM and peripherals. The on–chip DRAM CONTROLLER can support up to 4M bytes DRAM and controls access to the unspecialized SYSTEM or Video DRAM. The CPU can access any memory location, even during active video display lines, thereby boosting SYSTEM performance.

Description : SYSTEM CONTROLLER and Bus Driver View

General Description
The DP8228/DP8228M, DP8238/DP8238M are SYSTEM CONTROLLER/bus drivers contained in a standard, 28-pin dual in-line package. The chip, which is fabricated using Schottky Bipolar technology, generates all the read and write control signals required to directly interface the memory and input/output components of the 8080A microcomputer family. The chip also provides drive and isolation for the bidirectional data bus of the 8080A microprocessor. Data bus isolation enables the use of slower memory and input/output components in a SYSTEM, and provides for enhanced SYSTEM noise immunity.

Features
Single chip SYSTEM CONTROLLER and bus driver for 8080A Microcomputer SYSTEMs
Allows use of multibyte CALL instructions for Interrupt Acknowledge
Provides user-selected single-level interrupt vector(RST 7)
Provides isolation of data bus
Supports a wide variety of SYSTEM bus structures
Reduces SYSTEM component count
DP8238/DP8238M provides advanced Input/Output Write and Memory Write control signals for large SYSTEM timing control
