Description
The SP3220ET is an IC chip designed as an RS-232 driver/receiver solution for portable and hand-held applications such as palmtop or notebook computers. This device features a charge-pump power supply with high efficiency that necessitates only 0.1µF capacitors for a 3.3V operation. With this charge pump, the SP3220ET is capable of providing true RS-232 performance from a single power supply in the range of +3.3V to +5.0V. It has a low-power shutdown mode where driver outputs and charge pumps are disabled, consuming less than 1µA of supply current.
Specifications and features
- Meets true RS-232 protocol operation from a +3.0V to +5.5V power supply.
- Minimum 120 Kbps data rate under full load.
- 1µA low-power shutdown with receivers active.
- Interoperable with RS-232 down to +2.7V power source.
- Pin-compatible with the MAX3221E device without the AUTO ON-LINE® feature.
- ESD specifications: +2kV human body model.
Application Scenarios
The SP3220ET chip solution is ideal for portable and hand-held applications, such as palmtop or notebook computers that require true RS-232 performance from a single power supply in the range of +3.3V to +5.0V.
