SC6800H2-240G - Brand New SPREADTRUM IC Chips
-
Description
The SC6800H2-240G is a quad universal asynchronous receiver/transmitter (QUART) that combines four enhanced Philips Semiconductors industry-standard UARTs with an innovative interrupt scheme to minimize host processor overhead. It is designed using Philips Semiconductors' high-speed CMOS process, offering a small die size, low cost, 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
