Product Summary
The HD6321FP is designed as peripheral interface adapter which provides the universal means of interfacing peripheral equipment to the HD6800 microprocessing unit (MPU). This HD6321FP is capable of interfacing the MPU to peripherals through two 8-bit bidirectional peripheral data buses and four control lines. No external logic is required for interfacing to most peripheral devices.
Parametrics
HD6321FP absolute maximum ratings: (1)supply voltage: -0.3 to +7.0 V; (2)input voltage: -0.3 to +7.0 V; (3)maximum output current: 10 mA; (4)maximum total output current: 100 mA; (5)operating temperature: -20 to +75 ℃; (6)storage temperature: -55 to +150 ℃.
Features
HD6321FP features: (1)two bidirectional 8-bit peripheral data bus for interface to peripheral devices; (2)two programmable control, data direction registers; (3)four individually controller interrupt input lines, two usable peripheral control outputs; (4)handshake control logic for input and output peripheral operation; (5)high impedance 3-state and direct transistor drive peripheral lines; (6)two TTL drive capability on any A and B side buffers.
