PI7C9X1170ACLE

Controllers Overview

The PI7C9X1170ACLE is a single-channel full-duplex UART bridge controller manufactured by Diodes Incorporated. It converts I2C-bus or SPI protocols to RS-232/RS-485/RS-422 serial data. The device features 64-byte transmitter and receiver FIFOs, supports baud rates up to 16Mbit/s with a 4X sampling clock, and handles SPI clock speeds up to 33Mbit/s. It operates on a wide voltage range of 1.62V to 3.6V (1.8V, 2.5V, or 3.3V) and includes up to eight programmable GPIO pins. The internal register set is fully compatible with the industrial standard 16C450.

Controllers Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm package type and temperature range. The 'ACLE' designation corresponds to the TQFN-24 package variant. Confirm RoHS compliance and lead-free status requirements for your assembly process. Ensure the selected variant matches the required operating temperature range for your specific application environment.

Controllers Selection Notes

Select this component when a low-power, small-footprint UART bridge is needed for I2C or SPI interfaces. It is suitable for battery-operated devices due to its low standby current. Choose this part if backward compatibility with 16C450 software drivers is required. Consider the 33Mbps SPI speed and 16Mbit/s UART rate for high-performance serial communication needs in embedded systems.
