PI7C9X760BBLE - I2C/SPI to UART Bridge | Diodes Incorporated
料号： PI7C9X760BBLE ✓ 量产中PI7C9X760BBLE 概述
The PI7C9X760BBLE belongs to the interface-controller product class. Interface ICs sit within the broader integrated-circuit hierarchy and provide the hardware boundary between processors, sensors, transceivers, and communication equipment. A bridge such as this device is useful when a system already uses I2C or SPI on one side but requires a UART interface for a module, debugger, display, sensor, or communication peripheral on the other side.
Diodes Incorporated describes the PI7C9X760BBLE as an I2C/SPI-to-UART bridge controller. The related PI7C9X760BBLEX listing identifies the same device family in a 16-TSSOP package, while the related PI7C9X760BCLE listing identifies a TSSOP-16 variant. The verified component information confirms the controller function, industrial temperature grade, gull-wing terminal form, 16 terminals, and TSSOP package code. Detailed electrical timing, supply-voltage, and current-limit values require confirmation from the manufacturer datasheet before final circuit release.
Typical uses include industrial instrumentation, embedded control boards, test equipment, and communication adapters where a processor bus must connect to a UART peripheral. Because the bridge is intended for serial protocol translation, the host interface, UART logic levels, baud-rate behavior, and electrical standards should be checked against the specific system requirements. The 16-TSSOP format is suitable for compact surface-mount assemblies but requires careful layout around the fine-pitch leads and adequate soldering clearance.
Design work should begin with the manufacturer datasheet, including the pin-description table, recommended operating conditions, timing diagrams, and application circuit. The exact pin assignments cannot be reproduced from the product listings alone. Confirm the device's supply requirements, interface voltage levels, reset or enable behavior, and supported baud-rate range before selecting decoupling, pull-up, and level-shifting components.
This page provides practical engineering context for the PI7C9X760BBLE, including its bridge role, package identity, sourcing links, and the key design checks that should be completed before PCB release.

典型应用
PI7C9X760BBLE 适用于 6 应用s: Embedded Serial Protocol Adapters, Industrial Sensor and Module Interfaces, Test and Measurement Equipment, IoT Gateway Boards, Communications Equipment, Programming and Debug Adapters.
Embedded Serial Protocol Adapters
The PI7C9X760BBLE fits embedded boards that expose I2C or SPI to a processor while needing to connect a UART peripheral. Its I2C/SPI-to-UART bridge role reduces the need for a host controller to emulate a second serial protocol in software. The TSSOP-16 package also keeps the conversion circuit compact. Before schematic release, confirm the supported host rates, UART baud range, logic thresholds, and exact pin functions in the manufacturer datasheet.
推荐
Industrial Sensor and Module Interfaces
The PI7C9X760BBLE is appropriate for industrial control assemblies where sensors or radio modules use UART but the controller board communicates through I2C or SPI. Its industrial temperature-grade classification supports use in industrial equipment, subject to confirmation of the exact operating-temperature limits. The bridge can centralize protocol conversion, while external level translation may still be required when the UART side operates at non-TTL voltage levels.
推荐
Test and Measurement Equipment
The PI7C9X760BBLE can connect a tester controller that uses I2C or SPI to an instrument peripheral with a UART interface. This arrangement simplifies firmware organization by keeping each bus transaction in its natural protocol. In a bench instrument, connector protection, ground strategy, and UART voltage levels should be reviewed carefully. Confirm timing margins and maximum supported rates before using the bridge in a synchronized measurement path.
推荐
IoT Gateway Boards
PI7C9X760BBLE-based designs can bridge a low-speed processor bus to a UART-connected cellular, positioning, or configuration module in an IoT gateway. The 16-TSSOP package is useful where board area is constrained and where a dedicated protocol-conversion IC is preferable to software emulation. The design must still account for module supply voltage, boot timing, signal levels, and the maximum UART data rate supported by both devices.
推荐
Communications Equipment
The PI7C9X760BBLE is suitable for communication subsystems that need a UART connection to a module while the host processor uses I2C or SPI. It can reduce connector count on densely populated control boards and separate protocol-specific handling from the main application processor. For production equipment, validate the bridge against the module's electrical interface, including voltage levels, ground reference, baud rate, and any hardware flow-control requirements.
推荐
Programming and Debug Adapters
The PI7C9X760BBLE can assist compact programming or debug adapters that accept commands through I2C or SPI from a supervisory controller and present a UART endpoint to a target device. This can organize a multi-protocol debug accessory around one small bridge package. Firmware designers should use the datasheet timing diagrams to establish command framing, timeout behavior, and reset sequencing before the adapter is connected to production targets.

设计说明
Route I2C, SPI, and UART signals as short, controlled-impedance traces where appropriate, and keep the bridge close to the processor or connector that drives the relevant bus. Confirm the TSSOP-16 land pattern, pin-one orientation, and courtyard clearance against the manufacturer package drawing. Provide a continuous ground reference beneath and around the device, while avoiding long stubs on high-rate SPI or UART nets.
Assign the bridge's supply pins and decoupling requirements from the manufacturer recommended application circuit. Place the local bypass capacitor at the supply and ground pins with a short current-loop path, then reserve additional filtering only if the host rail contains significant switching ripple. Do not select the external capacitor value or operating voltage until the datasheet supply range and stability guidance are confirmed.
Do not treat the suffix variants as interchangeable without checking the ordering table. Confirm whether the selected order code changes tape-and-reel format, lead finish, or device revision, and verify every numbered TSSOP terminal from the pin-description table. Also confirm whether the UART interface requires external level translation or flow control; the bridge function alone does not guarantee compatibility with RS-232 or RS-485 voltage levels.
Establish protocol timing from the manufacturer timing diagrams, including setup and hold requirements for I2C and SPI transactions and the relationship between host commands and UART output. If either serial interface operates at a high rate, minimize discontinuities, provide a solid return path, and avoid placing test points or stubs adjacent to clock and data nets. Use an oscilloscope or protocol analyzer during hardware bring-up to verify framing and setup times.
