TL16C752BTPTREP

TL16C752BTPTREP is Texas Instruments’ quad UART (four independent 16C550-compatible UARTs) used to add four serial ports to a microcontroller or processor system. Each UART supports the standard 16C550-style register set with its own baud-rate generator, data framing (8/N/1, parity options), and modem/status signals. The device provides hardware buffering and interrupt capability to reduce CPU load in multi-port serial applications. It typically interfaces to RS-232/RS-485 line drivers (external) or TTL-level serials, and uses a common control interface that is software-compatible with earlier 16C550 devices.
Common use cases include multi-port serial adapters, embedded systems, data loggers, and telecom/industrial equipment where multiple serial channels are needed in a single IC.
The suffixes PTREP indicate packaging: the device is provided in a reel/tape-and-reel format suitable for automated assembly (specific packaging details are in the datasheet). For exact electrical specs (clock requirements, FIFO sizes, interrupt mapping, timing), refer to the TL16C752B datasheet.

TL16C752BTPTREP is a dual UART device (two 16550‑compatible channels) with the following key features:
- Two independent UARTs, each 16550-compatible
- Independent baud-rate generators per channel
- 16-byte receive and transmit FIFOs on each channel
- Programmable data formats: 5–8 data bits, parity (None, Odd, Even, Mark, Space), 1–2 stop bits
- Data register access via the standard 16550-compatible register set (DLAB for baud divisor)
- Per-channel interrupts for RX, TX, and line status
- Hardware handshake support via RTS/CTS and modem control lines
- Software and hardware reset options
- Suitable for PCI/embedded serial I/O with common PC‑style serial software drivers
Note: For exact pinout, voltage, timing, and package details, consult the official TI datasheet.
