6520 PERIPHERAL ADAPTER
DESCRIPTION
The 6520 Peripheral Adapter is designed to solve a broad range of peripheral control problems in
the implementation of microcomputer systems. This device allows a very effective trade-off between
software and hardware by providing significant capability and flexibility in a low cost chip. When
coupled with the power and speed of the 6500 family of microprocessors, the 6520 allows
implementation of very complex systems at a minimum overall cost.
Control of peripheral devices is handled primarily through two 8-bit bi-directional ports. Each of
these lines can be programmed to act as either an input or an output. In addition, four peripheral
control/interrupt input lines are provided. These lines can be used to interrupt the processor or for
"hand-shaking" data between the processor and a peripheral device.
FEATURES
• High performance replacement for Motorola/AMI
/MOSTEK/Hitachi peripheral adapter.
• N channel, depletion load technology, single +5V supply.
6520
• Completely Static and TTL compatible.
• CMOS compatible peripheral control lines.
• Fully automatic "hand-shake" allows very positive control
of data transfers between processor and
peripheral devices.
