General Description

: The NTE6821 is a peripheral interface adapter (PIA) in a 40–Lead DIP type package capable of interfacing the Microprocessing Unit (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.

The functional configuration of the PIA is programmed by the MPU during system initialization.

Key Features

  • D 8.
  • Bit Bidirectional Data Bus for Communication with the MPU D Two Bidirectional 8.
  • Bit Buses for Interface to Peripherals D Two Programmed Control Registers D Two Programmed Data Direction Registers D Four Individually.
  • Controlled Interrupt Input Lines; Two Usable as Peripheral Control Outputs D Handshake Control Logic for Input and Output Peripheral Operation D High.
  • Impedance 3.
  • State and Direct Transistor Drive Peripheral Lines D Program Controlled Inter.
