Lead-free Green PRODUCT BRIEF PI7C9X762Q Automotive I2C-Bus/SPI to UART Bridge Controller with 64 Bytes of TX/RX FIFOs Description Features
y The PI7C9X762Q is a I2C-bus/SPI to a dual-channel high per- AEC-Q100 Grade 2 Compliant y formance UART bridge control er. It offers data rates up to Dual channel full-duplex UART y Supports I2C-bus or SPI interface 33Mbps and guarantees low operating and sleeping current. y 64 bytes FIFO (transmitter and receiver) The PI7C9X762Q also has up to 8 additional programmable y Fully compatible with industrial standard 16C450 and equivalent general purpose I/O [GPIO] pins. The device comes in very y Baud Rates up to 16Mbit/s in 4X sampling clock rate small TQFN32 packages, which makes it ideal y suitable for y Programmable character formatting cost efficient, handheld, battery operated applications. These à 5-bit, 6-bit, 7-bit or 8-bit character UART bridges provide protocol conversion from I2C -bus or à Even, odd, or no parity SPI to RS-232/RS-485/RS-422 and are ful y bidirectional. à 1, 1.5, or 2 stop bits y The PI7C9X762Q supports SPI clock speeds up to 33Mbps Programmable Receive and Transmit FIFO trigger levels y and IrDA SIR up to 1.152Mbit/s. Special character detection y Internal Loopback mode The PI7C9X762Q’s internal register set is backward-compat- y Line break generation and detection ible with the widely used and widely popular 16C450 UART.
Flow Control
The PI7C9X762Q also provides additional advanced features y Supports hardware flow control using RTS/CTS such as auto hardware and software flow control, automatic y Supports software flow control with programmable Xon/Xoff RS-485 support, support for fractional baud rates and soft- characters ware reset. This al ows the software to reset the UART at any y Programmable single or double Xon/Xoff characters moment, independent of the hardware reset signal.
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
Application(s)
y Built-in IrDA encoder and decoder interface y y Telematics Supports IrDA SIR with speeds up to 115.2kbit/s (optional 1.152Mbps) y ADAS y Up to eight user programmable GPIO pins y Smart Cockpits y Software reset y Zonal Gateways
