1. General description
2. Features
The SC16C852L is a 1.8 V, low power, dual 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 SC16C852L is pin compatible with the SC16C652B. SC16C852L
can be programmed to operate in extended mode (see
advanced UART features are available. The SC16C852L UART provides enhanced UART
functions with 128-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 specific user requirements. An internal
loopback capability allows on-board diagnostics. Independent programmable baud rate
generators are provided to select transmit and receive baud rates.
The SC16C852L with Intel (16 mode) or Motorola (68 mode) bus host interface operates
at 1.8 V and is available in plastic LQFP48, TFBGA36 and very small (Micro-UART)
HVQFN32 packages.
