Data Sheet

2. Description

The IA82510 is an asynchronous serial controller that provides a CPU interface to one transmit

and one receive channel. It is Form, Fit, and Function compatible with the Intel 82510.

Configuration registers are used to control the serial channel, interrupts, and modes of operation.

The CPU controls this device via address and data lines with read/write control. The CPU also

uses this interface to read and write data to receive and transmit data through the serial channel.

FIFOs and various serial modes can be used to help off-load the CPU from transmitting and

receiving data. An interrupt line provides an indication to the CPU that the device requires

servicing. The device can be configured for 8250A/16450 compatibility. See Figure 2,

Functional Block Diagram.
