Overview
The XR88C192CJTR-F is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data rates up to 230.4 kbps. The device features 16-byte transmit and receive FIFOs for each channel, enhancing throughput efficiency. It is housed in a 44-pin PLCC package with J-leads, designed for surface-mount installation. The component functions across an industrial temperature range from 0°C to +70°C and includes internal oscillators and timers/counters.
Feature Summary
- Dual UART channels with independent 16-byte FIFO buffers
- Supports Motorola and Intel bus compatibility modes
- Integrated internal oscillator and programmable timer/counters
- Configurable GPIO pins for system flexibility
Applications
- Industrial communication systems requiring reliable serial data transfer
- Embedded controllers needing multiple asynchronous serial interfaces
- Motorola or Intel bus-compatible legacy system integration
Procurement Notes
This component is officially discontinued and no longer in production. Verification should focus on historical datasheets and discontinuation notices rather than current availability. Sourcing requires checking authorized distributors for remaining stock or evaluating qualified replacement parts that match the electrical and pinout specifications.
Selection Notes
Select this part only if specific compatibility with Motorola or Intel bus protocols is required alongside dual UART functionality. The 44-pin PLCC package necessitates appropriate PCB footprint design. Engineers must account for the discontinued status when planning long-term production runs and ensure alternative components are validated for form, fit, and function.
Part Context
The XR88C192 series belongs to MaxLinear's VLIO UART family, providing high-performance serial communication solutions. This specific variant utilizes the PLCC package format, distinguishing it from LQFP or SOIC versions within the same functional family. It serves as a bridge between parallel microprocessor buses and asynchronous serial devices.
Replacement Considerations
Verify pin-to-pin compatibility with other XR88C192 variants such as XR88C192CV-F or XR88C192CJ-F. Ensure the substitute maintains the 44-pin PLCC package and 16-byte FIFO architecture. Cross-reference datasheets for any differences in operating voltage ranges or temperature specifications.
