Description
The SC26C94A1A is a quad universal asynchronous receiver/transmitter (QUART) that combines four enhanced Philips Semiconductors industry-standard UARTs. It features an innovative interrupt scheme that minimizes host processor overhead. Built using Philips Semiconductors’ high-speed CMOS process, this component offers a combination of small die size, cost-efficiency, and low power consumption.
Specifications and Features
- New low overhead interrupt control
- Four Philips Semiconductors industry-standard UARTs
- Eight byte receive FIFO and eight byte transmit FIFO for each UART
- Programmable data format:
- 5 to 8 data bits plus parity
- Odd, even, no parity or force parity
- 1, 1.5 or 2 stop bits programmable in 1/16-bit increments
- Baud rate for the receiver and transmitter selectable from:
- 23 fixed rates: 50 to 230.4K baud Non-standard rates to 1.0M baud
- User-defined rates from the programmable counter/timer associated with each of two blocks
- External 1x or 16x clock
- Parity, framing, and overrun error detection
