MAX3108EWA+T

Overview

The MAX3108EWA+T is a universal asynchronous receiver-transmitter (UART) featuring 128-word receive and transmit FIFOs. It operates from a supply voltage of 1.71V to 3.6V with a maximum baud rate of 24Mbps. The device supports SPI interfaces up to 26MHz and I2C Fast Mode Plus up to 1MHz. Supply current is 500µA max, reducing to 35µA in shutdown mode. It includes an integrated PLL, fractional baud-rate generator, four GPIOs, and IrDA encoder/decoder. The component is housed in a 25-bump WLP package measuring 2.1mm x 2.1mm and is specified for temperatures from -40°C to +85°C.

Feature Summary

• Integrated phase-locked loop and fractional baud-rate generator for high-resolution programming

• Point-of-sale systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm lead-free status and temperature range compliance. Ensure that the package dimensions and pinout match the design requirements before finalizing procurement. Cross-reference the datasheet revision date to ensure all electrical characteristics are current.

Selection Notes

Select this component when a small form factor UART is required for low-power portable applications. Verify that the system clock frequency aligns with the internal PLL capabilities for the desired baud rate. Confirm that the available GPIO count meets the interface requirements and that the operating voltage range matches the target power supply rails.

Part Context

This part belongs to the MAX3108 family of serial interface controllers. It is designed as a register-compatible alternative to previous generations like the MAX3107. The device integrates standard UART functionality with modern serial bus interfaces, targeting space-constrained embedded designs requiring reliable data transmission.

Replacement Considerations

The MAX3107 is documented as a register-compatible predecessor. Verify pinout compatibility and feature parity before substitution. No other direct replacement part numbers are confirmed in the provided source material.
