SCC2698BC1A84,512

The SCC2698B Enhanced Octal Universal Asynchronous Receiver/Transmitter (Octal UART) by NXP Semiconductors is a single-chip MOS-LSI communications device providing eight full-duplex asynchronous receiver/transmitter channels in a single package. Fabricated with CMOS technology, it offers high density and low power consumption.

This Octal UART supports programmable data formats including 5 to 8 data bits plus parity, with options for odd, even, no parity, or force parity. It can be configured for 1, 1.5, or 2 stop bits. The operating speed for each receiver and transmitter can be selected independently from 26 fixed baud rates (50 to 38.4K baud) or user-defined rates via a programmable counter/timer or external clock inputs. Error detection for parity, framing, and overrun is included, along with false start bit detection and line break detection/generation.

Designed for surface mounting, the SCC2698BC1A84,512 comes in an 84-PLCC package. It operates from a single +5V power supply and is fully TTL compatible. Features include configurable GPIO, an internal oscillator, and timer/counter capabilities. It also supports auto flow control and modem control.

This device is an upwardly compatible version of the 2698A Octal UART, offering enhancements such as receiver ready or FIFO full status outputs and transmitter empty status outputs for each channel on 16 multipurpose I/O pins. The multipurpose pins provide DMA and modem control.
