PRODUCTION DATA. TL16C750E SLLSF10 – DECEMBER 2019 TL16C750E UART with 128-Byte FIFO 1 1 Features 1 • Supports wide supply voltage range of 1.62 V to 5.5 V – 6 Mbps (48-MHz oscillator input clock) at 5 V and 3.3 V – 3 Mbps (48-MHz oscillator input clock) at 5 V and 3.3 V – 2 Mbps (32-MHz oscillator input clock) at 3.3 V – 1.5 Mbps (24-MHz oscillator input clock) at 2.5 V – 1 Mbps (16-MHz oscillator Input clock) at 1.8 V • Characterized for operation from –40°C to 105°C • 128-byte transmit or receive FIFO • 6-bit fractional baud rate divider • Software-selectable baud-rate generator • Programmable and selectable transmit and Receive FIFO Trigger Levels for DMA, interrupt generation, and software or hardware flow control • Software/Hardware flow control – Programmable Xon and Xoff characters with optional Xon any character – Programmable Auto-RTS and Auto-CTS- modem control functions (CTS, RTS, DSR, DTR, RI, and CD) • DMA signaling capability for both received and transmitted data • RS-485 mode support • Infrared data association (IrDA) capability • Programmable sleep mode • Programmable serial interface characteristics – 5, 6, 7, or 8-bit characters with 1, 1.5, or 2 stop bit generation – Even, odd, or no parity bit generation and detection • False start bit and line break detection • Internal test and loopback capabilities 2 Applications • Industrial computing • Communications equipment • White goods 3 Description The TL16C750E is a single universal asynchronous receiver transmitter (UART) with 128-byte FIFOs, fractional baud rate support, automatic hardware, software flow control and data rates up to 6 Mbps. The device offers enhanced features such as fractional baud rate and a transmission character control register (TCR) that stores received FIFO threshold level to start or stop transmission during hardware and software flow control automatically without intervention from the CPU. With the FIFO RDY register, the software gets the status of TXRDY or RXRDY, saving extra GPIO usage. On-chip status registers provide the user with error indications, operational status, and modem interface control. System interrupts may be tailored to meet user requirements. An internal loop-back capability allows onboard diagnostics. The TL16C750E incorporates the functionality of UART, the UART having its own register set and FIFO. This version includes the Alternate Function Register (AFR) and this is used to enable some extra functionality beyond the capabilities of the TL16C750 version. One addition is the IrDA mode, which supports Standard IrDA (SIR) mode with baud rates from 2400 to 115.2 kbps. The third addition is support for RS-485 bus drivers or transceivers by providing an output pin (DTRx) per channel, which is timed to keep the RS-485 driver enabled as long as transmit data is pending.
