SP3227EEY-L/TR

Drivers, Receivers, Transceivers Overview

The SP3227EEY-L/TR is a single-driver, single-receiver RS-232 transceiver from MaxLinear. It operates on a +3.0V to +5.5V supply and supports data rates up to 1 Mbps. The device features Auto On-line® Plus technology for automatic low-power shutdown upon inactivity. It includes an integrated charge pump requiring four external capacitors and provides ±15kV ESD protection on I/O pins. The component is housed in a 16-pin TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Auto On-line® Plus automatically manages power states by entering low-power shutdown during idle periods and waking instantly upon signal activity without software intervention.
• Integrated regulated charge pump generates stable RS-232 voltage levels from a single low-voltage power supply using minimal external capacitance.
• High-speed data transmission capability of 1 Mbps with driver slew rates not limited for rapid transitions.

Drivers, Receivers, Transceivers Applications

• Diagnostic and serial ports on embedded applications
• Handheld test equipment
• PC-related peripherals and equipment
• Battery-powered equipment
• Point-of-sale equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) and 'Y' denotes the TSSOP-16 package configuration. Confirm RoHS compliance status through official manufacturer documentation or distributor specifications prior to finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a single full-duplex channel is required for high-speed communication at 1 Mbps. Ensure the design accommodates the 16-pin TSSOP footprint and utilizes the recommended 0.1μF charge pump capacitors for optimal performance within the specified voltage range.

Drivers, Receivers, Transceivers Part Context

This component belongs to the SP3224E-SP3227E series of 3.0V to 5.5V RS-232 transceivers. It serves as a drop-in replacement for legacy devices such as the MAX3227 and ICL3227, offering enhanced power efficiency through proprietary Auto On-line® Plus circuitry while maintaining standard RS-232 compatibility.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed direct substitutes include MAX3227 and ICL3227. These components share identical pinouts and functional specifications, allowing for straightforward integration into existing designs requiring single-channel high-speed RS-232 connectivity.

Drivers, Receivers, Transceivers FAQ

How does the Auto On-line® Plus feature function?

It automatically detects idle conditions lasting more than 30 seconds to enter a low-power shutdown state, drawing only 1µA. It wakes up immediately upon detecting any signal transition on the receiver or driver inputs.

What is the maximum data rate supported by the SP3227E?

The SP3227E supports a maximum data rate of 1 Mbps under loaded conditions (3kΩ parallel with 250pF).

Does the device provide ESD protection?

Yes, the RS-232 I/O pins are protected against electrostatic discharge up to ±15 kV according to the Human Body Model.
