PI7C9X760BCLE - 33Mbps I2C/SPI to UART Bridge | Diodes
MPN: PI7C9X760BCLE ✓ AktifPI7C9X760BCLE Genel Bakış
An I2C/SPI-to-UART bridge is an interface-controller IC that allows a host processor or another digital subsystem to communicate with a UART peripheral through a serial bus that the host already supports. In the electronic-component hierarchy, the PI7C9X760 belongs to interface controllers, interface ICs, and integrated circuits. This bridge architecture can reduce peripheral connection requirements in handheld, battery-operated, embedded, and cost-sensitive equipment.
Key features include support for both I2C and SPI host-side buses, one high-performance UART channel, operation at data rates up to 33 Mbps, and low operating and sleeping current. The manufacturer identifies up to eight programmable GPIO pins as an additional expansion capability. These features make the controller useful when a design must expose legacy UART equipment through a compact serial interface while retaining peripheral control connections.
The PI7C9X760BCLE is supplied in a 16-pin TSSOP package. Its small surface-mount format supports compact assemblies, while the tube packaging identified for this ordering code is intended for production handling through automated assembly equipment. Because the bridge is intended for space-constrained equipment, careful attention to interface levels, signal routing, clocking, and supply decoupling remains important during PCB implementation.
Typical applications include industrial serial gateways, handheld test and measurement equipment, battery-powered data loggers, embedded control systems, serial protocol adapters, and embedded service interfaces. In each case, the bridge can provide a defined path between I2C or SPI system buses and UART-compatible downstream equipment. Selection should include checking protocol support, baud-rate requirements, logic thresholds, pin mapping, and package compatibility against the host platform.
Design the PCB with short, continuous signal paths and place decoupling capacitance close to the device supply pins. Confirm the exact electrical limits, configuration method, clock requirements, and UART signaling details in the manufacturer datasheet before schematic release. The use of a known package footprint alone does not establish complete functional equivalence when replacing an existing bridge.
This product page combines the manufacturer's PI7C9X760 architecture information with package, ordering, sourcing, and practical interface-design guidance. It also distinguishes documented drop-in replacements from general cross-reference tools, helping engineers evaluate compatibility before committing to a board revision.

Handheld Data Loggers
The PI7C9X760BCLE fits handheld data loggers that must expose a UART-equipped sensor or radio through an I2C or SPI host processor. Its manufacturer-stated throughput of up to 33 Mbps provides margin for burst-oriented serial traffic, while low operating and sleeping current are central to its positioning for battery-operated equipment. The 16-pin TSSOP also helps conserve board area in compact enclosures. Use the bridge between the host serial interface and the peripheral UART, configure the protocol and baud rate in firmware, and verify the logic levels and sleep behavior against the system timing. The low-power suitability must be assessed in the complete logger because sensor activity, radio transmission, and host wake cycles can dominate the final battery life.
Önerilen
Industrial Serial Gateways
Industrial serial gateways often combine a modern processor with equipment that still exposes only UART. The PI7C9X760BCLE can provide the bridge between an I2C- or SPI-connected host and that legacy UART endpoint, with a supported rate of up to 33 Mbps. The 16-pin TSSOP package supports compact gateway designs where several conversion functions may share limited PCB space. Configuration should align the bridge clock, UART baud rate, framing, parity, and flow-control requirements with the connected equipment. Because industrial environments can include long cables and noisy neighboring circuits, the implementation must maintain clean signal routing, suitable termination, and compatible logic thresholds rather than relying on package dimensions alone to establish reliability.
Önerilen
Embedded Serial Adapters
The PI7C9X760BCLE is appropriate for embedded serial adapters that need to make a UART peripheral accessible from an I2C or SPI controller. Its dual host-side bus options allow the same bridge family to support different processor interfaces, while the single UART channel serves as the downstream endpoint. At data rates up to 33 Mbps, the device can accommodate demanding serial links, but the selected mode must remain within the detailed timing and operating limits in the manufacturer documentation. Designers should create a clear mapping between bus commands, GPIO functions, and UART frames, then include startup and sleep behavior in system testing to prevent stale or incomplete data when the host changes operating modes.

Battery-Powered Sensor Terminals
In a battery-powered sensor terminal, the PI7C9X760BCLE can connect an I2C or SPI host to a UART-based sensor, modem, or configuration interface. The manufacturer's emphasis on low operating and sleeping current makes the device appropriate for designs that spend substantial time between active transactions. Its 16-pin TSSOP footprint also leaves room for the power-management circuitry, sensor, and communications hardware in a compact board. To obtain the intended low-power benefit, firmware should avoid unnecessary bridge activity and use the documented sleeping configuration. Developers must also account for wake-up latency, clock stability, and the fact that the overall power budget also includes the host controller and connected wireless or sensor subsystem.

Test and Measurement Instruments
The PI7C9X760BCLE can serve as a protocol-conversion element in compact test and measurement instruments whose controller uses I2C or SPI but whose internal instrument or fixture uses UART. The bridge's stated throughput of up to 33 Mbps and support for up to eight programmable GPIO pins allow the design to combine high-speed data transfer with auxiliary control functions. The small TSSOP package is valuable in bench instruments where front-panel controls, display circuitry, and measurement channels already consume board area. Firmware should define stable UART framing and bus transactions to simplify diagnostics. Before layout release, verify the bridge's pin assignments, clock source, signal voltage domains, reset behavior, and any test points needed to diagnose communication failures.
Önerilen
Portable Communication Accessories
Portable communication accessories can use the PI7C9X760BCLE to connect a host processor to a UART-based modem, configuration port, or peripheral while keeping the external interface standardized. The controller's combination of I2C or SPI host connectivity and one UART channel makes it useful for accessories where the enclosure exposes limited connector space. Its low-current operating and sleeping characteristics suit portable equipment, and the 16-pin TSSOP package supports compact production assemblies. The implementation should define how the host selects the active bus, how commands map to UART frames, and how GPIO lines participate in modem control. Mechanical connector placement, cable protection, logic-level compatibility, and host firmware sequencing should be checked as part of the complete accessory design.

Tasarım Notları
Use the manufacturer package drawing to confirm the 16-pin TSSOP footprint, lead width, pitch, and board-outline clearance before PCB release. Place the device so that I2C, SPI, UART, clock, and power paths remain short, and route sensitive serial signals away from switching nodes. The 4.40 mm package width is known, but it should not be used alone to create the footprint because solder mask, paste, and land-pattern details must match the official drawing.
Assign the host interface, UART lines, clock, control signals, and programmable GPIO functions before laying out the board. Keep pull-up placement consistent with the final I2C topology and selected logic voltage, and avoid unnecessary stubs on high-speed UART routes. If any protocol signal crosses a board or cable boundary, incorporate the electrical protection and grounding strategy required by the complete system rather than treating the bridge's logic pins as protected I/O.
Confirm the bridge's supply range, operating current, sleeping current, and all pin voltage limits in the manufacturer datasheet before selecting the regulator and decoupling network. Place the required input and output capacitors at the pins specified by the reference circuit, using the shortest possible ground returns. A low-power design should measure both active and sleeping behavior with the real host firmware, since bus activity and peripheral wake cycles can change the total system load.
Do not treat a generic UART transceiver as a functional drop-in replacement for this bridge. Verify the 16-pin TSSOP pin map, I2C and SPI protocol behavior, UART configuration, clock source, GPIO multiplexing, supply requirements, and timing together. Also confirm that the BCLE ordering code corresponds to the required tube packaging and that the PCB assembly process matches the 96-piece tube format.
