Integrated Circuit  
Peripheral Interface Adapter (PIA),  
NMOS, 1MHz  
Description:  
The NTE6821 is a peripheral interface adapter (PIA) in a 40–Lead DIP type package capable of inter-  
facing 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. Each  
of the peripheral data lines can be programmed to act as an input or output, and each of the four con-  
trol/interrupt lines may be programmed for one of several control modes. This allows a high degree  
of flexibility in the over–all operation of the interface.  
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 Interrupt and Interrupt Disable Capability  
D CMOS Drive Capability on Side A Peripheral Lines  
D Two TTL Drive Capability on All A and B Side Buffers  
D TTL Compatible  
D Static Operation

Note 1. This device contains circuitry to protect the inputs against damage due to high static voltages  
or electric fields; however, it is advised that normal precautions be taken to avoid application  
of any voltage higher than maximum rated voltages to this high impedance.
