Overview
The SP3232EEN-L is a high-performance RS-232 transceiver produced by MaxLinear, Inc. This device is part of the SP3232E series, designed to meet the true EIA/TIA-232-F standards from a single power supply ranging from +3.0 V to +5.5 V. It is particularly suited for portable or hand-held applications such as notebook or palmtop computers due to its low power consumption and compact package.
The SP3232EEN-L features MaxLinear’s proprietary on-board charge pump circuitry, which generates the necessary RS-232 voltage levels from a single power supply, making it ideal for 3.3V-only systems, mixed 3.3V to 5.5V systems, or 5.0V-only systems.
