6509 MICROPROCESSOR WITH MEMORY MANAGEMENT
DESCRIPTION
The 6509 is a low -cost m icroprocessor capable of solving a broad range of sm all-system s and
memory managem ent problems at m inimum cost to the user.
A m em ory m anagem ent system allows for up to One M ega-Byte of m em ory for ease in down loading
languages, operating systems or other data.
The Three-State sixteen-bit Address Bus allows Direct Memory Accessing (DMA) and m ulti
processor systems sharing a com m on memory while the Four-bit Extended Address Register allows for
up to one Mega-byte of data storage.
The internal processor architecture is identical to the Com m odore Sem iconductor Group 6502 to
provide software compatibility.
