Diodes Incorporated Lead-free Green PRODUCT BRIEF PI7C9X762Q Automotive I2C-Bus/SPI to UART Bridge Controller with 64 Bytes of TX/RX FIFOs
Description Features The PI7C9X762Q is a I2C-bus/SPI to a dual-channel high performance UART bridge controller. It offers data rates up to
33Mbps and guarantees low operating and sleeping current.
The PI7C9X762Q also has up to 8 additional programmable
general purpose I/O [GPIO] pins. The device comes in very
small TQFN32 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 RS-232/RS-485/RS-422 and are fully bidirectional.
The PI7C9X762Q supports SPI clock speeds up to 33Mbps
and IrDA SIR up to 1.152Mbit/s.
The PI7C9X762Q's internal register set is backward-compatible with the widely used and widely popular 16C450 UART.
The PI7C9X762Q 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. y AEC-Q100 Grade 2 Compliant
y Dual channel full-duplex UART
y Supports 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 …
