CS82C52 概述
A UART is a serial communication interface that converts parallel data from a controller into a framed serial stream and converts received serial data back into parallel data. The CS82C52 combines this UART function with a programmable baud-rate generator, placing transmit timing, receive timing, and serial-channel control in one CMOS interface IC. This integration reduces the number of external timing components compared with a UART implemented from separate logic.
The verified material describes the CS82C52 as a high-performance programmable UART and BRG on a single chip. Its programmable architecture makes it suitable for systems in which the communication rate must be selected by the host controller or fixed through configuration logic. The RS232 classification identifies the electrical-interface class used by the associated UART function, while the actual board-level signal levels still depend on the transceiver and system design.
Typical uses include embedded serial controllers, legacy industrial control equipment, peripheral interfaces, and communications systems that require a dedicated UART channel. The 28-pin PLCC package provides a defined leaded surface-mount footprint, allowing the part to be used where a compact, inspectable package is preferable to a fine-pitch package. The available data does not provide complete electrical timing tables, supply-voltage limits, or all pin-level details, so those specifications require confirmation from the manufacturer datasheet.
For replacement work, engineers should verify the exact package, pin assignments, electrical limits, timing, temperature grade, and software-visible register behavior before approving a substitute. The device is an older CMOS interface component, so lifecycle status and sourcing should be confirmed at the time of procurement. Pricing and inventory are also time-sensitive and should be checked against current distributor records.

典型应用
CS82C52 适用于 6 应用s: Embedded Serial Controller Interface, Legacy Industrial Control Communication, Peripheral Communication Port, Legacy Test and Measurement Equipment, RS-232 Point-to-Point Data Links, Legacy Data Acquisition Interface.
Embedded Serial Controller Interface
The CS82C52 fits legacy embedded controllers that need a dedicated asynchronous serial channel instead of a software-emulated UART. Its verified description identifies programmable UART and baud-rate-generator functions on one CMOS chip, allowing the controller to use a hardware-assisted serial interface for command exchange or peripheral communication. The 28-pin PLCC package provides a defined leaded footprint for systems designed around this legacy interface family. Before layout release, verify the complete pinout, supply limits, logic levels, timing, and any required external RS232 transceiver; those details are not fully present in the supplied verified data.
推荐
Legacy Industrial Control Communication
The CS82C52 can be used in older industrial-control equipment where a dedicated UART and baud-rate generator simplifies serial communication between a controller and a peripheral. The verified Intersil description confirms programmable UART and BRG functionality, while the distributor listing identifies a one-channel RS232 UART IC in a 28-PLCC package. A complete legacy system may require level conversion, isolation, and careful signal grounding. Verify timing, reset behavior, and electrical limits in the manufacturer documentation before adapting it to a new controller; the supplied data does not provide those detailed values.
推荐
Peripheral Communication Port
The CS82C52 is appropriate for a peripheral subsystem that needs an independent asynchronous serial port for status, configuration, or control data. Its integrated baud-rate generator helps centralize the timing function, which is useful when the host controller has limited serial resources or when deterministic baud-rate programming is required by the original system. The 28-pin PLCC package is suitable for a board design explicitly intended for that footprint. The CS82C52 does not by itself specify the external line standard, so an appropriate transceiver, connector, and protection network must be added after reviewing the actual electrical requirements.
推荐
Legacy Test and Measurement Equipment
The CS82C52 can support a serial control or data port in legacy test and measurement equipment where a hardware UART is preferable to bit-banged serial transmission. The verified device description confirms programmable UART and baud-rate-generator operation, and the 28-PLCC package is identified by the distributor listing. In an instrument, the UART timing must remain compatible with the existing controller software and the external communications standard. Verify supply voltage, electrical timing, reset behavior, and package pin assignments from the manufacturer datasheet before production use.
推荐
RS-232 Point-to-Point Data Links
The CS82C52 can form the logical UART portion of a point-to-point RS-232 communications link when paired with an appropriate line transceiver. The verified distributor description classifies the CS82C52 as an RS232 UART IC, while the device description confirms programmable UART and BRG functionality. The UART handles framing and serial timing; the transceiver handles voltage conversion and line protection. Because the complete electrical timing and logic-level information is not included in the supplied data, engineers must confirm compatibility with the selected MAX232-family or other transceiver before releasing the circuit.
推荐
Legacy Data Acquisition Interface
The CS82C52 may be used as a serial control interface for a legacy data-acquisition subsystem that predates modern USB or network communication. Its programmable baud-rate generator can provide a dedicated timing source for communicating with measurement hardware, a controller board, or a service port. The 28-pin PLCC package means the mechanical design is constrained to that footprint, so replacement or modernization should be treated as a deliberate PCB decision. Verify whether the associated system expects RS-232, another physical standard, or a proprietary voltage-level interface, and confirm all pin and timing details from the authoritative datasheet.

关键差异点

- Dedicated one-channel serial interface （对比 Software-emulated serial port)
- Defined 28-pin PLCC mechanical format （对比 Generic modern UART with a different footprint)
设计说明
Treat the CS82C52 as a UART/BRG logic device rather than as a complete RS-232 physical layer. Confirm whether the existing board includes a separate line driver, receiver, protection network, or connector. A logic-level UART and an RS-232 transceiver have different voltage domains, so removing or bypassing the transceiver can damage the device. Use the manufacturer pinout and interface schematic before changing the board.
The verified distributor record identifies a 28-PLCC package measuring 11.51 mm by 11.51 mm. Before PCB assembly or replacement, compare the land pattern, pin numbering, orientation mark, and exposed or thermal features against the actual package drawing. Do not infer the footprint from the family name because related 82C52 variants may use PLCC, CLCC, CERDIP, or other package forms.
The available temperature data distinguishes CS82C52, IS82C52, and MD82C52/B variants, so the exact ordering suffix must be checked before using the part in an industrial or extended-temperature design. The supplied material does not provide full electrical-limit or timing tables. Validate the selected suffix against the complete manufacturer datasheet rather than treating the family-level temperature entries as universal specifications.
合规信息
The supplied verified data does not state RoHS, REACH, halogen-free, conflict-minerals, or AEC-Q100 status. The component is an older CMOS interface IC, but compliance cannot be inferred from its category or manufacturer.
