ST16C452IJ68PS-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C452IJ68PS-F is a dual universal asynchronous receiver and transmitter (DUART) manufactured by MaxLinear. It operates within a supply voltage range of 2.97V to 5.5V and supports data rates up to 1.5Mbps. The device integrates a single-byte FIFO for both transmit and receive channels. It features a configurable general-purpose input/output (GPIO), a bidirectional parallel printer port, and timer/counter capabilities. The component is housed in a 68-lead PLCC package with J-leads.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates two independent UART channels with one-byte FIFO buffers for each direction.
• Includes a bi-directional parallel port designed for printer interface applications.
• Provides configurable GPIO pins and integrated timer/counter functionality.
• Supports standard Intel and Motorola bus protocols for flexible system integration.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring serial communication

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

This component is listed as obsolete or no longer manufactured by the producer. Availability is restricted to existing stock or third-party distributors. Verify authenticity and condition carefully when sourcing from secondary markets. Ensure compatibility with legacy system requirements before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this part for designs requiring a combined DUART and parallel port solution in a compact PLCC package. Consider the single-byte FIFO limitation for high-throughput applications where larger buffers are needed. Verify that the 68-pin footprint matches the PCB layout constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The ST16C452 series belongs to MaxLinear's VLIO UART family, combining serial and parallel interfaces. This specific variant offers a dual UART configuration alongside a printer port, suitable for legacy interface preservation in modern embedded designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

As the product status is obsolete, direct substitutes may be limited. Check for pin-compatible alternatives from the same manufacturer's current portfolio or consider functional equivalents with similar FIFO depths and interface configurations.
