ISL8563IP - 3V-5.5V 250kbps RS-232 Interface | Renesas
MPN: ISL8563IP ✗ انتهى عمره الإنتاجيISL8563IP نظرة عامة
An RS-232 transceiver is an interface IC that converts logic-level digital signals into RS-232 voltage levels and converts received RS-232 signals back into logic-compatible levels. Within the broader semiconductor hierarchy, it belongs to the interface IC family, alongside line drivers, receivers, transceivers, and communications interface devices. The ISL8563IP specifically addresses systems that need bidirectional serial communication without using a 5V-only RS-232 implementation.
Three headline characteristics make the ISL8563IP useful in compact equipment. Its 3.0V-to-5.5V operating supply supports both 3.3V and 5V system rails. Its guaranteed 250kbps minimum data rate permits substantially faster communication than conventional low-speed serial links. Its 1uA operational supply current supports power-conscious portable equipment. The manufacturer datasheet also states that only four external 0.1uF capacitors are required, simplifying the surrounding analog and digital interface circuitry.
Technically, the device combines powered transmitters and receivers designed to meet EIA/TIA-562 and EIA/TIA-232 specifications. The dual-standard positioning is important because EIA/TIA-562 was developed for lower-voltage RS-232-compatible links, while EIA/TIA-232 describes conventional RS-232 electrical characteristics. The verified device description explicitly confirms operation at VCC = 3.0V, rather than requiring the 5V supply traditionally associated with classic RS-232 parts.
Typical uses include PDAs, palmtop computers, notebook computers, and other portable or compact systems with low-voltage RS-232 links. The ISL8563IP is also appropriate for point-to-point serial connections, equipment interfaces, and embedded control links where the system supply is 3.3V or 5V. Its 250kbps capability can shorten communication time when the connected equipment and protocol support that rate.
A key design consideration is that the external capacitors must be placed close to their associated device pins, and the board must maintain adequate separation between RS-232 driver outputs and receiver inputs to limit noise coupling. Designers should also verify that the connected equipment uses compatible signal levels and baud rates. The verified material does not expose the complete pin assignment, so the published package drawing should be consulted before PCB routing.
This product record combines verified electrical capabilities, sourcing information, availability data, and application guidance in one engineering-oriented reference. It also clearly distinguishes confirmed manufacturer specifications from unavailable details rather than estimating pin assignments, package dimensions, temperature limits, or lifecycle details.

التطبيقات النموذجية
ISL8563IP مناسب لـ 6 التطبيقs: Low-Voltage RS-232 Serial Links, PDA and Palmtop Equipment, Notebook and Laptop Peripherals, Portable Test and Measurement Devices, Embedded Equipment Configuration Ports, Industrial Controller Communication.
Low-Voltage RS-232 Serial Links
The ISL8563IP fits low-voltage RS-232 links because its 3.0V-to-5.5V supply range includes 3.3V systems while preserving EIA/TIA-562 and EIA/TIA-232 behavior down to 3.0V. A guaranteed 250kbps minimum data rate can reduce transfer time relative to slow serial interfaces. The device is used between a host UART and an external RS-232 port, with four external 0.1uF capacitors providing local high-frequency support.

PDA and Palmtop Equipment
The ISL8563IP was specifically targeted by the manufacturer toward PDAs and palmtop computers where low operational supply current and compact external support are important. Its 1uA operational supply current and 3.0V-to-5.5V operating range align with low-voltage portable platforms. The interface can connect a serial controller to an RS-232 accessory while requiring only four external 0.1uF capacitors according to the manufacturer data sheet.
موصى به
Notebook and Laptop Peripherals
The ISL8563IP is appropriate for notebook and laptop peripheral connections that rely on RS-232 and operate from a 3.3V or 5V internal rail. Its guaranteed 250kbps data rate is useful for legacy synchronization, configuration, or diagnostic links, while EIA/TIA-562 support extends compatibility to lower-voltage RS-232-style links. Designers still need to verify connector pinouts, cable length, signal polarity, and the baud rate supported by the attached peripheral.
موصى به
Portable Test and Measurement Devices
The ISL8563IP can support portable test and measurement equipment that needs a conventional RS-232 control port without requiring a dedicated 5V-only transceiver. Its 3.0V minimum supply supports low-voltage logic systems, and the 250kbps guarantee provides a defined minimum communications rate. In such equipment, the benefit is integration flexibility, although exact legacy-device compatibility and connector voltage levels must be checked against the target instrument.
موصى به
Embedded Equipment Configuration Ports
The ISL8563IP is usable for embedded configuration or service ports when the board uses a 3.3V control logic and must communicate through an RS-232 connector. Its EIA/TIA-562 capability is relevant for systems using reduced RS-232 voltage levels, while the 5.5V upper limit allows operation from a 5V rail. Engineers should confirm that the UART baud rate is at or below 250kbps and account for the four required external 0.1uF capacitors.
موصى به
Industrial Controller Communication
The ISL8563IP can be used in industrial controller boards that retain an RS-232 service or legacy equipment port while operating from a 3.3V or 5V rail. The guaranteed 250kbps rate and EIA/TIA-562/EIA/TIA-232 support provide defined interface criteria, but industrial qualification requirements are not stated in the verified sources. Review temperature, ESD, isolation, grounding, and EMC requirements separately before using the device in safety-critical or high-noise installations.

ملاحظات التصميم
Place the four required 0.1uF capacitors as close as practical to their associated ISL8563IP pins. Keep capacitor return paths short and continuous, avoid routing them beneath areas with high switching current, and use a common-ground reference that minimizes loop area. The exact capacitor connections must be confirmed against the complete manufacturer schematic because those connections were not exposed in the supplied excerpts.
Keep RS-232 driver outputs away from receiver inputs and other sensitive logic nets to reduce capacitive and inductive coupling. A 250kbps-capable interface still requires controlled return paths, especially near switching regulators, relays, clocks, or high-current motor lines. Preserve the EIA/TIA-562 and EIA/TIA-232 system topology recommended by the manufacturer rather than treating the transceiver as a generic UART buffer.
Do not assume that a generic RS-232 transceiver is a drop-in replacement. Confirm package dimensions, lead numbering, power pin locations, driver and receiver pin functions, external capacitor connections, and operating-voltage behavior. The verified ISL8563IP description specifically emphasizes operation down to VCC = 3.0V and compliance with both EIA/TIA-562 and EIA/TIA-232, so those requirements must be checked in any proposed substitute.
معلومات الامتثال
The verified manufacturer description confirms EIA/TIA-562 and EIA/TIA-232 electrical specifications. No verified RoHS, REACH, lead-free, halogen-free, or conflict-minerals statements were supplied; AEC-Q100 is treated as not applicable because this is an interface IC rather than an automotive-qualified device.
