Description

MAX3233EEWP is Maxim’s RS-232 transceiver kit (an evaluation board) built around the MAX3233 family. It provides two RS-232 drivers and two RS-232 receivers, so you can connect a microcontroller or UART to a PC/modem-style RS-232 port and vice versa. The device converts TTL/CMOS logic levels to RS-232 voltage levels and back, enabling serial communication over RS-232.
Operates from a single supply (roughly 3.0–5.5 V) and uses an on-chip charge pump to generate the required RS-232 voltages from that supply. External charge-pump capacitors are required per the datasheet. The EEWP suffix indicates an Evaluation Kit, so the board includes connectors and cables to test the transceivers and prototype RS-232 links easily.
Typical use cases: interface a microcontroller’s UART to a PC RS-232 port, developers’ debugging tools, or RS-232 links in embedded systems. It’s a compact, low‑power solution for converting TTL serial to RS-232 in a single-supply package.

Features

Here are the key features of the MAX3233EEWP (RS-232 transceiver) and its evaluation board:
- Dual RS-232 transceiver: 2 drivers and 2 receivers (TX/RX channels)
- Single-supply operation: 3.0 V to 5.5 V (typical 3.3 V)
- On-chip charge pump: generates RS-232 voltages from a single supply
- RS-232 level outputs: typically ±6 V swing
- TTL/CMOS inputs: logic-compatible with Vcc
- Data rate: up to about 250 kbps (RS-232 signaling)
- External pump capacitors: requires four 0.1 µF capacitors (C1–C4)
- ESD/robustness on RS-232 lines
- Small package (typical for MAX3233 family) and RoHS Pb-free
- Evaluation board features: DB9 RS-232 connector, voltage/power options, header pins for easy interfacing, plug-and-play for quick testing
Note: Exact temperature range and some electrical specs may vary by revision; check the datasheet for the precise variant you have.

Package

8-pin Small Outline package (SO-8), RoHS lead‑free.

Pinout

- Pin count: 20 pins (EEWP package)
- Function: Triple RS-232 transceiver. Provides three independent transmitter channels and three independent receiver channels (TTL/CMOS side: T1in, T2in, T3in and R1out, R2out, R3out; RS-232 side: T1out, T2out, T3out and R1in, R2in, R3in). Uses an onboard charge-pump with external capacitors (C1+, C1−, C2+, C2−) to generate ±RS-232 voltages from a single supply (Vcc, GND).

Manufacturer

Manufacturer: Maxim Integrated.
What kind of company: An American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits; Maxim was acquired by Analog Devices in 2021 and now operates as part of Analog Devices.

Application

RS-232 serial interface for 3.3V embedded systems. Applications include microcontrollers/SBCs, modems, printers, POS terminals, data-acquisition and measurement equipment, industrial control/automation gear, network/telecom equipment, and portable/battery-powered devices requiring a compact, low-power RS-232 transceiver.

Equivalent

Equivalent RS-232 transceivers (2 Tx/2 Rx with charge pump, 3–5.5 V) to MAX3233EEWP include:
- TI SP3232E/SP3232
- STMicroelectronics ST3232/ST3232E
- Analog Devices ADM232/ADM232A
These provide similar functionality; verify pinout/package and voltage range in datasheets. Also, MAX3232/ MAX3233 variants from Maxim are direct relatives.
