Product Summary
The MC6821P peripheral interface adapter(PIA) provides the universal means of interfacing peripheral equipment to the M6800 family of microprocessors. The MC6821P 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
MC6821P absolute maximum ratings: (1)supply voltage: -0.3 to +7.0 V; (2)input voltage: -0.3 to +7.0 V; (3)operating temperature range: -40 to +85 ℃; (4)storage temperature range: -55 to +150 ℃.
Features
MC6821P features: (1)8-bit bidirectional data bus for communication with the MPU; (2)two bidirectional 8-bit buses for interface to peripherals; (3)two programmable control registers; (4)two programmable data direction registers; (5)four individually-controlled interrupt input lines; two usable as peripheral control outputs; (6)handshake control logic for input and output peripheral operation; (7)high-impedance three-state and direct transistor drive peripheral lines; (8)program controlled interrupt and interrupt disable capability; (9)CMOS drive capability on side A peripheral lines; (10)two TTL drive capability on all A and B side buffers; (11)TTL-compatible; (12)static operation.
