Rockwell R6500/1 family
The R6500/1 is a 6502 , ROM (2K) 64 bytes RAM ,4×8 bit I/O, a 16 bit timer with I/O pin.
The ROM contents are factory mask-programmed, not programmable by the user.
This makes it a standalone microcomputer, no extra RAM/ROM or decode logic required.
There are no external address lines or data lines, the 6502 is all internal except the interrupt lines and clock.
Rockwell R6500/1EC
To develop applications with the R6500/1 Rockwell developed the R6500/1EC. This IC has the same pins as the R6500/1 but adds address and data lines and relies on an external ROM.
