DP8224 Clock Generator and Driver
General Description
The DP8224is aclock generator/drivercontainedina stan-
dard, 16-pin dual-in-line package. The chip, whichis fabri-
cated using Schottky Bipolar technology, generates clocks
and timingforthe 8080A microcomputer family.
Includedinthe DP8224isan oscillator circuit thatis con-
trolledbyan external crystal, whichis selectedbythede-
signerto meeta varietyof system speed requirements. Also
includedinthechipare circuitsthat provide:a status strobe
forthe DP8228or DP8238 system controllers, power-onre-
setforthe 8080A microprocessor, and synchronizationof
the READY inputtothe 8080A.
Features Crystal-controlled oscillatorfor stable system operation Single chip clock generatorand driverfor 8080A micro-
processor Provides status strobefor DP8228or DP8238 system
controllers Provides power-on resetfor 8080A microprocessor Synchronizes READY inputto 8080A microprocessor Provides oscillator outputfor synchronizationof exter-
nal circuits Reduces system component count
