SC16C652
Dual UART with 32 bytes of transmit and receive FIFOs
Rev. 04 鈥?20 June 2003
Product data
1. 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 speci铿乧 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.
