SC16C652
Datasheet
General description
The SC16C652 is a 2 channel Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data and vice versa. The UART can handle serial data rates up to 5 Mbits/s. The SC16C652 is pin compatible with the SC16C2550. It will power-up to be functionally equivalent to the 16C2450. The SC16C652 provides enhanced UART functions with 32-byte FIFOs, modem control interface, DMA mode data transfer. The DMA mode data transfer is controlled by the FIFO trigger levels and the TXRDY and RXRDY signals. On-board status registers provide the user with error indications and operational status. System interrupts and modem control features may be tailored by software to meet specific user requirements. An internal loop-back capability allows on-board diagnostics. Independent programmable baud rate generators are provided to select transmit and receive baud rates.
The SC16C652 operates at 5 V, 3.3 V and 2.5 V and the Industrial temperature range, and is available in a plastic LQFP48 package.
