In modern electronic devices, drivers, receivers, and transceivers are crucial interface components for data transmission and reception. Among them, the ICL3221ECVZ-T, an RS-232 transceiver produced by Intersil (now part of Renesas Electronics), boasts various advanced features and specifications, finding widespread application in personal digital assistants (PDAs), handheld computers, laptops, and other low-power devices. This article will delve into the key specifications and characteristics of the ICL3221ECVZ-T.
Key Specifications
Supply Voltage:
Minimum Supply Voltage: 3V
Maximum Supply Voltage: 5.5V
Nominal Supply Voltage: 3.15V
The ICL3221ECVZ-T supports a wide range of supply voltages, from 3V to 5.5V, enabling compatibility with various power systems, including 3.3V and 5V systems.
Operating Temperature:
Minimum Operating Temperature: 0°C
Maximum Operating Temperature: 70°C
The device can operate normally within a temperature range of 0°C to 70°C, suitable for various environmental conditions.
Package:
Package Type: TSSOP-16
Package Size: Small outline, thin, reduced pitch
The TSSOP-16 package allows the ICL3221ECVZ-T to occupy minimal space on the board, facilitating space savings on the circuit board.
Data Rate:
Maximum Data Rate: 250kbps
Even under the worst load conditions, the device guarantees a data rate of 250kbps, meeting the needs of most low-speed data transmission.
Pins:
Number of Pins: 16
Pin Form: GULL WING
Pin Pitch: 0.6500mm
Pin Coating: MATTE TIN
The 16 pins provide abundant interface options, and the GULL WING pin form allows the device to be mounted using surface-mount technology, enhancing production efficiency.
Main Characteristics
ESD Protection:
Offers ±15kV ESD protection (compliant with IEC61000-4-2 standard)
The ICL3221ECVZ-T provides up to ±15kV of electrostatic discharge (ESD) protection on the emitter outputs and receiver inputs (RS-232 pins), enhancing system reliability.
Low Power Consumption:
Standby Current: 1μA
The device reduces the standby current to 1μA through an efficient on-chip charge pump and manual and automatic power-down functions (except for ICL3232E), thereby lowering the overall system power consumption.
Automatic Power-Down Function:
When connected peripheral devices are turned off or the RS-232 cable is removed, the automatic power-down function turns off the on-chip power supply and driver circuits, further conserving system power.
Compatibility:
Fully compatible with 3.3V systems, mixed 3.3V and 5.0V systems, and 5.0V systems
Compliant with EIA/TIA-232 and V.28/V.24 specifications
The ICL3221ECVZ-T not only supports multiple voltage systems but also complies with industry standards, ensuring compatibility and reliability with existing systems.
Small Package:
The use of a small outline package and low-value capacitors further saves circuit board space.
Noise Immunity:
The receiver features hysteresis, enhancing immunity to noise and stabilizing data transmission.
Replacement Products:
Directly replaces MAX3221E, MAX3222E, MAX3223E, MAX3232E, MAX3241E, MAX3243E, and SP3243E equivalents.
The ICL3221ECVZ-T offers a pin-compatible, low-power alternative to these products, simplifying design and production processes.
Application Areas:
PDAs, handheld computers, laptops, and other low-power devices
These devices have stringent requirements for low power consumption and minimal standby power, making the ICL3221ECVZ-T an ideal choice to meet these needs.
Conclusion
The ICL3221ECVZ-T is a powerful, low-power RS-232 transceiver with a wide supply voltage range, high data rate, robust ESD protection, automatic power-down functionality, and compatibility with multiple systems. Its small package and noise immunity make it an excellent choice for PDAs, handheld computers, laptops, and other low-power devices. By providing stable data transmission and efficient power management, the ICL3221ECVZ-T enhances the overall performance and reliability of systems, meeting the dual demands of high performance and low power consumption in modern electronic devices.
