CP2108-B01-GM 개요
A USB-to-UART bridge is an interface IC that translates a USB host transaction into one or more UART signals for serial peripherals. This device belongs to the USB interface-controller and UART-interface hierarchy, with USB 2.0 full-speed connectivity, four serial channels, modem-control signals, and on-chip customization storage. The B01-GM ordering code identifies the manufacturer's device and package configuration; the manufacturer datasheet also identifies B01-GM as a revision marking.
The CP2108 includes four asynchronous UART data buses with full modem-control signals. Its on-chip EEPROM can customize the USB Vendor ID, Product ID, product description string, power descriptor, device release number, and interface strings. The USB product page identifies 16 digital I/O pins and a 9 x 9 mm QFN64 package. The manufacturer documentation describes the CP2108 as a USB 2.0-compliant device suitable for multiport serial-interface designs.
Because the device combines USB control, four UART channels, EEPROM customization, and digital I/O in one package, it can reduce the component count and PCB area of a four-port serial bridge. The integrated USB transceiver and oscillator simplify the host-side connection compared with a discrete USB implementation. Four UART ports allow equipment such as test systems, instrumentation, industrial controllers, and service equipment to expose multiple serial devices through one USB connection.
Typical system implementation places the CP2108 between a USB connector and four external serial ports. Board design must preserve the datasheet pin assignments, provide the required decoupling and power routing, and account for the exposed-pad thermal and electrical requirements of the QFN package. Host software must use a compatible CP210x USB-to-UART driver, while USB VID, PID, and product strings can be managed through the supported customization process described by the manufacturer.
The CP2108-B01-GM is useful when a product needs four UART channels, modem-control signals, digital I/O, and a compact USB interface. It is also suitable for legacy serial designs that need to migrate to USB without retaining a large collection of external interface components. Its key design tradeoff is integration versus firmware support: the device simplifies hardware, but the host must have compatible drivers and the firmware must handle four independent UART channels and any required custom USB identity.
This page summarizes the verified manufacturer and distributor references, the CP2108 family architecture, package information, and practical replacement considerations. Because the provided data does not expose every electrical limit, pin-level function, lifecycle statement, or current distributor price for the exact CP2108-B01-GM, those fields are marked as needed rather than estimated.

일반적인 애플리케이션
CP2108-B01-GM 적합 용도: 6 애플리케이션s: Industrial Serial Test Equipment, RS-232 to USB Migration, Multiport Instrumentation, Industrial Controller Gateway, USB-to-Serial Service Console, Legacy Peripheral Consolidation.
Industrial Serial Test Equipment
The CP2108-B01-GM is suited to industrial test equipment that must expose several serial-controlled instruments through one USB connection. Its four asynchronous UART data buses and full modem-control signals let a host manage four independent serial channels without four separate USB interface ICs. The 16 digital I/O pins can support peripheral status, fixture control, or trigger signaling when the system architecture requires them. A host driver must enumerate all four ports, and external RS-232 or RS-485 electrical transceivers remain necessary when the connected equipment uses those physical standards. The 9 mm x 9 mm QFN64 footprint helps reduce board area, but exposed-pad routing and four-channel signal integrity require careful layout.
추천
RS-232 to USB Migration
The CP2108-B01-GM provides a practical bridge for legacy RS-232 equipment that needs a USB host connection. Its USB 2.0 full-speed function controller and integrated transceiver reduce the host-side interface complexity, while four UART buses allow one board to consolidate multiple serial links. Each legacy port still needs the correct RS-232 voltage-level transceiver, wiring protection, and connector implementation. Firmware can present the four UARTs as separate COM ports or combine them into a proprietary transport, provided the host software and drivers are configured accordingly. The integrated EEPROM can also preserve product-specific USB identity during the migration.
추천
Multiport Instrumentation
Instrumentation systems often need several low-speed control and measurement links close to the host computer. The CP2108-B01-GM can provide four UART channels in one compact interface IC, reducing USB bridge count and simplifying host-side enumeration. Full modem-control signals are useful when a connected instrument uses request-to-send, clear-to-send, or other handshake lines. The 16 digital I/O pins can provide additional discrete control where the instrument needs trigger or status signals. Because the CP2108 handles USB enumeration and UART conversion rather than analog measurement, the analog front end and instrumentation-specific interface electronics must still be designed separately.
추천
Industrial Controller Gateway
The CP2108-B01-GM can form the serial side of an industrial controller gateway connected to a USB host such as a gateway computer, test station, or service console. Four UART buses allow multiple downstream controllers or sensors to share one USB interface, while the integrated EEPROM supports product-specific USB descriptors. The device is useful when a legacy controller ecosystem already uses UART rather than Ethernet or a modern high-speed fieldbus. Firmware must implement routing, timeout handling, and error recovery for each channel. If the external links are RS-485, isolated transceivers, termination, protection, and grounding must be added according to the target network design.
추천
USB-to-Serial Service Console
A service console or configuration tool can use the CP2108-B01-GM to connect a host computer to four serial targets. The USB 2.0 full-speed interface is suitable for configuration, logging, and control traffic rather than high-throughput storage transfers. The four channels can connect to separate boards, sensors, or service ports, and full modem-control signals can support legacy handshaking. The device's integrated EEPROM helps maintain product identity across different service-console variants. A robust implementation should expose port selection clearly, handle simultaneous channel activity, and provide OS driver support for predictable enumeration. External transceiver selection depends on whether each target uses RS-232, RS-485, or another electrical interface.
추천
Legacy Peripheral Consolidation
The CP2108-B01-GM can consolidate several legacy peripheral interfaces into one USB-connected board. A single package contains the USB controller, transceiver, oscillator, EEPROM, four UARTs, and digital I/O, reducing the number of separate bridge components. This is useful when a product has retained multiple serial peripherals but wants a single USB cable to a modern host. The board designer must allocate pins and routing for all four channels, verify the package's exposed-pad requirements, and provide the correct external line drivers. EEPROM customization can distinguish the product from generic CP2108-based adapters. Software should validate channel status and serial settings before attempting a connection.

- Compact QFN64 implementation (vs CP2108-B03-GM)
설계 노트
Route the four UART channels and associated modem-control signals according to the manufacturer pinout and recommended layout. Keep USB differential routing short, controlled, and away from noisy UART outputs where practical. The verified data identifies a 9 mm x 9 mm 64-pin QFN package, but exact pin names, exposed-pad connections, and recommended land pattern must be taken from the official CP2108 datasheet before layout release.
The supplied data does not state the CP2108-B01-GM supply-voltage range or absolute maximum ratings. Do not infer power-rail values from the USB or UART interface descriptions. Confirm the electrical limits, decoupling requirements, and power-sequencing requirements in the official Silicon Labs datasheet, then validate startup and shutdown behavior across all four UART ports.
A same-package replacement is not automatically a functional replacement. The B01, B02, and B03 revisions may differ in USB descriptors, VID/PID, EEPROM customization, or revision-related behavior. The supplied cross-reference data identifies candidates, but it does not provide a complete exact-variant electrical comparison. Verify the manufacturer revision information, pinout, EEPROM contents, driver behavior, and production supply status before substitution.
The CP2108-B01-GM is an interface IC rather than a power semiconductor, so a Safe Operating Area chart is not applicable. Thermal design should still account for the QFN exposed pad and the actual package land pattern. The supplied data does not include junction-temperature limits or package thermal resistance; use the manufacturer package information for a validated thermal layout rather than estimating those values from device function.
규정 준수 정보
The supplied search data does not provide verified compliance statements for the exact CP2108-B01-GM. AEC-Q100 is not applicable because this is an interface IC rather than an automotive-qualified power or mixed-signal component. Check the current manufacturer product documentation for RoHS, REACH, lead-free, halogen-free, and conflict-minerals status.
