PI7C9X760ACLE

Pb Lead-free Green A Product Line of Diodes Incorporated PI7C9X760 I2C-Bus/SPI to UART Bridge Controller with 64 bytes of TX/RX FIFOs Features Features The DIODES PI7C9X760 is a I2C-bus/SPI to a single-channel high performance UART bridge controller. It offers data rates up to 33Mbps and guarantees low operating and sleeping current. The PI7C9X760 also has up to 8 additional programmable general purpose I/O [GPIO] pins. The device comes in very small TSSOP24 packages, which makes it ideally suitable for cost efficient, handheld, battery operated applications. These UART bridges provide protocol conversion from I2C -bus or SPI to RS232/RS-485/RS-422 and are fully bidirectional. The PI7C9X760 supports SPI clock speeds up to 33Mbps and IrDA SIR up to 1.152Mbit/s. The PI7C9X760’s internal register set is backward-compatible with the widely used and widely popular 16C450 UART. The PI7C9X760 also provides additional advanced features such as auto hardware and software flow control, automatic RS-485 support, support for fractional baud rates and software reset. This allows the software to reset the UART at any moment, independent of the hardware reset signal. This allows the software to reset the UART at any moment, independent of the hardware reset signal. y Single channel full-duplex UART y Support I2C-bus or SPI interface y 64 bytes FIFO (transmitter and receiver) y Fully compatible with industrial standard 16C450 and equivalent y Baud Rates up to 16Mbit/s in 4X sampling clock rate y Programmable character formatting à 5-bit, 6-bit, 7-bit or 8-bit character à Even, odd, or no parity à 1, 1.5, or 2 stop bits y Programmable Receive and Transmit FIFO trigger levels y Special character detection y Internal Loopback mode y Line break generation and detection Flow Control y Support hardware flow control using RTS/CTS y Support software flow control with programmable Xon/Xoff characters y Programmable single or double Xon/Xoff characters Interface Control y Automatic RS-485 slave address detection y RS-485 driver direction control via RTS signal y RS-485 driver direction control inversion y Built-in IrDA encoder and decoder interface y Supports IrDA SIR with speeds up to 115.2kbit/s (optional 1.152Mbps) y Up to eight user programmable GPIO pins y Software reset Others y Low standby current at 3.3V y Wide operation voltage (1.8V, 2.5V or 3.3V) y Industrial and commercial temperature ranges I2C Interface y Compliant with I2C-bus fast speed y Support slave mode only y Crystal oscillator (up to 24MHz) or external clock (up to 64MHz) input SPI Interface y Support 33 Mbit/s maximum SPI clock speed y Support SPI mode 0 (slave mode only) y Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) y Halogen and Antimony Free. “Green” Device (Note 3) y For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/104/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/ y Packaging (Pb-free & Green): à 16-contact, TSSOP (L) à 24-contact, TSSOP (L) à 24-contact, TQFN (ZD) Application(s) y Industrial Computing y Automation y Factory Process Control y Mobile Computing y Embedded Applications y Battery Operated Devices y Networking Notes:       1.
