Overview
The XR68C92IVTR-F is a dual-channel UART interface integrated circuit manufactured by MaxLinear, Inc. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data rates up to 1 Mb/s. The device features an 8-byte transmit and receive FIFO for each channel and utilizes a Motorola bus interface. It is housed in a 44-pin PLCC package with J-leads (PLCC-44) and is designed for surface-mount installation. The component functions as a serial I/O controller compatible with CMOS logic levels.
Feature Summary
- Dual independent UART channels with dedicated 8-byte FIFOs
- Motorola bus interface compatibility
- Low power operation with support for 3.3V and 5V supplies
Applications
- Industrial control systems requiring serial communication
- Embedded systems with multiple asynchronous serial ports
- Telecommunications equipment interfaces
Procurement Notes
Verify the specific suffix IVTR against official MaxLinear documentation to confirm pinout and electrical characteristics match design requirements. Confirm end-of-life status and availability through authorized distributors. Ensure RoHS compliance documentation is obtained prior to procurement.
Selection Notes
Select this component when dual UART functionality with FIFO buffering is required in a compact PLCC package. Verify that the system clock frequency supports the desired baud rate generation. Ensure the operating temperature range meets the application environment specifications.
Part Context
This part belongs to the XR68C192 series of VLIO UARTs from MaxLinear. It is functionally similar to other variants like the XR68C92CV-F but differs in packaging and potentially temperature grade. The IVTR suffix typically indicates a tape and reel packaging format for automated assembly.
Replacement Considerations
Check for direct pin-compatible replacements within the XR68C92 family. Verify if the XR68C92CV-F or XR68C92CJTR-F can substitute based on package and temperature requirements. Consult MaxLinear for current recommended alternatives.
