SC16C652BIBS,151

SC16C652BIBS,151 is a 2-channel universal asynchronous receiver and transmitter with 32-byte FIFOs and an infrared encoder/decoder. It is used for serial data communications. Its principal function is to convert parallel data into serial data and vice versa. It can handle serial data rates up to 5Mbit/s. The SC16C652B is pin-compatible with the SC16C2550. It will power up to be functionally equivalent to the 16C2450. It 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 active low TXRDY and active low 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.

• 5V tolerant on input only pins, Up to 5Mbit/s data rate at 5V and 3.3V, and 3Mbit/s at 2.5V
• 32-byte transmit FIFO to reduce the bandwidth requirement of the external CPU
• 32-byte receive FIFO with error flags to reduce the bandwidth requirement of the external CPU
• Independent transmit and receive UART control, supports IrDA version 1.0 (115.2kbit/s), sleep mode
• Automatic software (Xon/Xoff) and hardware (active low RTS/active low CTS) flow control
• Programmable Xon/Xoff characters, software selectable baud rate generator
• Standard modem interface or infrared IrDA encoder/decoder interface
• Standard asynchronous error and framing bits (start, stop, and parity overrun break)
• Transmit, receive, line status, and data set interrupts independently controlled
• HVQFN32 package, ambient temperature range from -40 to +85°C
