What are the key features of MAX3228AEEWV+?

Dual RS-232/EIA-232 transceiver (2 drivers, 2 receivers) in a single IC for complete UART port implementation
Wide supply range from 2.5 V to 5.5 V, covering 3.3 V and 5 V system rails without a separate charge pump supply
Schmitt-trigger inputs for noise immunity on slow or noisy RS-232 signal lines
Compliant with EIA-232, TIA-232, V.24, and V.28 interface standards
Ultra-compact 30-ball UCSP (wafer-level CSP) package minimizing board footprint in space-critical designs
Internal charge pump generates RS-232 voltage levels from a single low-voltage supply
Pb-free RoHS-compliant construction suitable for regulated-market electronics

What is MAX3228AEEWV+ used for?

MAX3228AEEWV+ is used in portable handheld terminals, embedded industrial gateways, and compact data-acquisition modules that require RS-232 serial port connectivity from a low-voltage supply rail without a separate ±12 V rail. Its miniature UCSP footprint is particularly valuable in wearable instruments, space-constrained PCBs, and high-density multi-port serial interface cards where traditional SOIC or TSSOP transceivers would consume too much board area.

Frequently Asked Questions

Can MAX3228AEEWV+ operate from a 3.3 V supply, and does it generate RS-232 voltage levels internally?

Yes. MAX3228AEEWV+ operates from 2.5 V to 5.5 V, which includes 3.3 V single-supply systems. An internal charge pump generates the ±5 V to ±12 V RS-232 driver output levels from the low-voltage supply, eliminating the need for an external dual-supply or separate DC-DC converter. This allows direct RS-232 port implementation from a 3.3 V MCU rail.

How many RS-232 channels does MAX3228AEEWV+ provide, and is it sufficient for a standard UART port with handshaking?

MAX3228AEEWV+ integrates 2 drivers and 2 receivers, providing 2 transmit and 2 receive channels. This covers a basic RS-232 UART port using TX and RX lines, but does not include RTS/CTS hardware handshaking lines. For full RTS/CTS flow control, a 4-driver/4-receiver variant or a higher-channel transceiver would be needed.

What is the UCSP package size and pitch of MAX3228AEEWV+, and how does it compare to the SOIC-16 form factor?

MAX3228AEEWV+ uses a 30-ball UCSP (wafer-level CSP) package with approximately 1.5 mm x 2.5 mm body and 0.5 mm ball pitch, which is substantially smaller than a standard SOIC-16 footprint measuring 10 mm x 4 mm. The wafer-level package reduces PCB area by roughly 80% compared to SOIC, enabling RS-232 transceiver integration in extremely space-constrained portable designs.

What is the significance of Schmitt-trigger inputs on MAX3228AEEWV+ for legacy RS-232 cable or long-line installations?

Schmitt-trigger receiver inputs apply hysteresis of typically 0.5 V, which prevents false triggering caused by slow signal edges or noise on long RS-232 cables. RS-232 signals at cable ends can have rise times in the microsecond range due to capacitive loading, and without hysteresis, a standard CMOS comparator input would oscillate as the signal crosses the threshold. The Schmitt-trigger inputs ensure clean logic output transitions even at low baud rates over cables exceeding 15 meters.

What interface standards does MAX3228AEEWV+ support, and does it fit legacy RS-232 equipment using V.24 or V.28 definitions?

MAX3228AEEWV+ complies with EIA-232, TIA-232, V.24, and V.28 standards, all of which define the same electrical characteristics for serial data communication: driver output voltage of ±5 V to ±15 V, receiver threshold between ±3 V, and data rates up to 20 kbps at standard cable lengths. This broad standard coverage ensures interoperability with legacy industrial terminals, modems, and measurement instruments still using V.24 or V.28 serial ports.
