SP3222EUEA-L

Drivers, Receivers, Transceivers Overview

The SP3222EUEA-L is a full-duplex RS-232 transceiver manufactured by MaxLinear, designed for portable and handheld applications. It operates on a single power supply ranging from +3.0V to +5.5V and features two drivers and two receivers. The device supports data rates up to 1 Mbps with a propagation delay of 0.15 µs. It includes a low-power shutdown mode reducing supply current to under 1 µA. ESD protection exceeds ±15 kV per human model and IEC standards. The component is housed in a 20-pin SSOP package and functions within an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Intelligent AUTO ON-LINE circuitry automatically wakes the device from microamp shutdown without external control signals.
• Regulated charge pump generates stable RS-232 voltage levels regardless of VCC variations using minimal external capacitance.
• Enhanced electrostatic discharge tolerance provides robust protection against high-voltage static events.

Drivers, Receivers, Transceivers Applications

• Portable computers and notebook systems
• Handheld devices and palmtop computers
• Industrial equipment requiring low-power serial communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix EA indicates the SSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected distributor provides traceable components to maintain quality assurance standards for embedded interface designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed 1 Mbps transmission within a compact surface-mount footprint. The integrated intelligent wake-up feature simplifies power management schemes compared to standard shutdown pins. Verify that the 20-pin SSOP layout fits the target PCB constraints before finalizing the bill of materials.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3222E/SP3232E series of true 3.0V to 5.5V RS-232 transceivers. The series is engineered to deliver full RS-232 performance from low-voltage single supplies. The EU designation typically denotes the high-speed 1 Mbps capability variant within the broader family.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include other SP3222 variants with different packages or speed ratings. Verify electrical parameters such as data rate and shutdown current when cross-referencing with generic RS-232 transceivers from other manufacturers.

Drivers, Receivers, Transceivers FAQ

How does the AUTO ON-LINE feature function?

The internal circuitry detects incoming signal activity and automatically transitions the device out of the low-power shutdown state, eliminating the need for a dedicated wake-up pin.

What is the minimum capacitor requirement for the charge pump?

The device requires only 0.1µF capacitors for the charge pump operation when powered by a 3.3V supply, minimizing external component count.

Does the shutdown mode disable the receivers?

In the standard low-power shutdown mode, the receivers remain active while the drivers and charge pump are disabled, allowing the device to detect wake-up signals.
