SECTION 1
INTRODUCTION
SUMMARY
The Rockwell R650011 microcomputer is a complete 8-bit com-
puter fabricated on a single chip using 'an N-channel silicon gate
MaS process. The R650011 complements an established and
growing line of R6500 products and has a wide range of microcom-
puter applications.
The R6500/1 consists of an R6502 Central Processing Unit (CPU).
2048 bytes of Read Only Memory (ROM). 64 bytes of Random
Access Memory (RAM) and interface circuitry for peripheral
devices.
The innovative architecture and the demonstrated high perfor-
mance of the R6502 CPU. as well as instruction simplicity. results
in system cost-effectiveness and a wide range of computational
power. These features make the R650011 a leading candidate for
microcomputer applications.
To facilitate system and program development for the R6500/1.
Rockwell has developed a 64-pin R6500/1E Emulator device, as
well as a pin-compatible R6500l1EB Backpack Emulator device.
For more information. refer to the data sheets for the R6500l1E
(Order No. D51S) and the R6500l1EB (Order No. D60).
This product description is for the reader familiar with the R6502
CPU hardware and programming capabilities. A detailed descrip-
tion of the R6502 CPU hardware is included in the R6500
Microcomputer System Hardware Manual (Document Order
No. 201). A description of the instruction capabilities of the R6502
CPU is contained in the R6500 Microcomputer Systems Program-
ming Manual (Document Order No. 202).
