SC16C652B
5 V, 3.3 V and 2.5 V dual UART, 5 Mbit/s (max.), with
32-byte FIFOs and infrared (IrDA) encoder/decoder
Rev. 03 鈥?10 December 2004
Product data
1. Description
The SC16C652B 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 Mbit/s. The SC16C652B is pin compatible with the SC16C2550. It will
power-up to be functionally equivalent to the 16C2450. The SC16C652B provides
enhanced UART functions with 32-byte FIFOs, modem control interface, DMA mode
data transfer, and IrDA encoder/decoder. 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鏗乧
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 SC16C652B operates at 5 V, 3.3 V and 2.5 V and the Industrial temperature
range, and is available in plastic LQFP48 and very small (Micro-UART) HVQFN32
packages.
