PI7C9X762CLE - 33Mbps Dual UART Bridge | Diodes
料号： PI7C9X762CLE ✓ 量产中PI7C9X762CLE 概述
An I2C/SPI-to-UART bridge is an interface controller within the broader interface IC category. I2C and SPI use clocked, host-oriented buses, while UART provides independent asynchronous serial channels. A bridge controller allows a host processor to configure, monitor, and exchange data with UART-connected sensors, displays, modems, or industrial equipment without implementing every low-level protocol conversion in host firmware. The PI7C9X762 therefore belongs to the serial-interface-controller and embedded communication-controller hierarchy.
The PI7C9X762 family provides dual-channel UART bridging, operation up to 33 Mbps, and as many as eight programmable GPIO pins. According to the Diodes Incorporated product page, the controller is designed around low operating and sleeping current, making it suitable for compact, cost-sensitive equipment. Its small TSSOP-28 package also supports space-constrained PCB layouts where a larger bridge or discrete level-shifting circuitry would be inconvenient.
The manufacturer describes the PI7C9X762 as an I2C-bus/SPI to dual-channel high-performance UART bridge controller. This architecture allows the host-side I2C or SPI connection to coexist with two UART channels in one package. The exact electrical limits, register map, operating-voltage range, and pin-level signal assignments are not included in the supplied verified excerpts, so engineers should consult the manufacturer datasheet before finalizing a board or power design.
Typical uses include industrial data acquisition, handheld test equipment, programmable serial adapters, embedded control panels, and battery-operated instruments. In these systems, the bridge can manage UART traffic while the host processor communicates through I2C or SPI. The dual-channel architecture may reduce external UART component count, while the maximum stated data rate of 33 Mbps supports communication well above common low-speed serial-console rates.
Design planning should account for protocol-specific level translation, signal integrity, device configuration, and firmware ownership of the bridge registers. The manufacturer indicates low operating and sleeping current, but the supplied data does not publish exact current values. Confirm supply voltage, absolute maximum ratings, UART logic levels, reset requirements, and all 28 pin assignments in the official datasheet before production release.
This product record combines the manufacturer description with verified distributor pricing, package, and order information. It also distinguishes verified PI7C9X762CLE availability from related ordering codes and unverified substitutes, helping engineers make sourcing and design decisions without relying on incomplete cross-reference listings.

Industrial Serial Data Acquisition
The PI7C9X762CLE is suitable for an industrial acquisition controller that gathers data from two UART-connected instruments while the main processor communicates over I2C or SPI. Its dual-channel UART architecture reduces the number of separate bridge devices, and the verified maximum data rate of 33 Mbps provides substantial throughput margin. Up to eight programmable GPIO pins can support equipment-enable, status, alarm, or isolation-control functions. The bridge is normally placed close to the instrument connectors, with separate routing for each UART channel and careful grounding to reduce noise pickup. Before deployment, verify the operating-temperature range, supply limits, UART electrical levels, and all 28 TSSOP-28 pin assignments against the manufacturer datasheet.
推荐
Handheld Programmable Test Instrument
The PI7C9X762CLE fits a handheld tester that exposes legacy serial equipment through a compact controller board. A host processor can use I2C or SPI to configure the bridge and access two UART channels, while the verified 33 Mbps capability covers fast data transfers and avoids forcing a lower-rate host interface onto a high-throughput design. The TSSOP-28 package conserves board area, and the manufacturer's description of low operating and sleeping current supports battery-operated form factors. Exact current consumption is not stated in the supplied excerpts, so engineers must obtain those values before estimating battery life. Firmware should also verify UART framing, parity, baud-rate configuration, and bus ownership during hot-plug or reconnect conditions.
推荐
Battery-Operated Field Sensor Interface
PI7C9X762CLE can bridge a host processor to two UART-based field sensors in battery-operated monitoring equipment. Its I2C or SPI host connection is useful when the central controller already uses a clocked bus, while two dedicated UART channels support devices with independent serial protocols. Diodes Incorporated identifies low operating and sleeping current as family characteristics, making power-conscious design feasible, although exact current values are not present in the verified excerpts. Use the lowest appropriate communication rate when energy use dominates, disable unused channels if the device supports that mode, and isolate sensor grounds where long external cables introduce noise. Confirm the missing electrical specifications and register-controlled shutdown behavior in the official datasheet.
推荐
Programmable Serial Adapter
The PI7C9X762CLE is appropriate for a programmable serial adapter designed to bridge a modern host bus to one or two UART peripherals. Its verified 33 Mbps maximum data rate supports high-throughput transfers, and the 28-pin TSSOP package keeps the converter compact enough for enclosure-mounted or embedded adapter boards. The host firmware can select I2C or SPI for the processor side and configure UART behavior on the peripheral side, reducing the need for discrete level-conversion or framing hardware. Include proper RS-232 or RS-485 transceiver stages when required rather than connecting external balanced lines directly to logic-level UART pins. Validate signal levels, timing margins, and pinout against the manufacturer documentation before fabrication.
推荐
Embedded Equipment Control Panel
The PI7C9X762CLE can serve as the serial gateway in an embedded control panel that connects a touchscreen or controller to UART-based front-panel modules. Two UART channels allow separate communication paths for a display and a keypad or peripheral, while the I2C/SPI host interface avoids dedicating multiple processor pins. The available GPIO count can supplement panel-control functions, and the TSSOP-28 package preserves board area in compact enclosures. Firmware should define ownership and timeouts for each channel to prevent one slow peripheral from blocking the other. Because the supplied verified excerpts do not provide logic-level thresholds, timing specifications, or the complete pin table, those details must be checked in the manufacturer datasheet before final interface and grounding decisions.
推荐
Communication Adapter for Peripheral Equipment
PI7C9X762CLE is suitable for communication adapters that let an embedded processor reach legacy or specialized UART peripherals through an I2C or SPI link. Its two-channel arrangement supports simultaneous or multiplexed serial connections, and the 33 Mbps maximum rate covers demanding transfer tasks. The compact TSSOP-28 package simplifies integration between a main processor board and a daughterboard containing legacy connectors. Engineers should add the correct line-driver or receiver for RS-232, RS-485, or other physical layers, because the bridge controller manages protocol and framing rather than every external electrical interface. Validate signal termination, isolation, connector protection, and the manufacturer-defined timing constraints before production.

设计说明
Place the PI7C9X762CLE close to the host controller and keep the I2C or SPI routing away from UART receive paths, especially when the bridge supports rates up to 33 Mbps. Route the two UART channels separately to their connectors, use a continuous ground reference, and place required bypass capacitors at the device supply and ground pins. The verified excerpts do not specify the recommended capacitor values or pin assignments, so obtain those details from the manufacturer datasheet before finalizing the layout.
Do not route external UART signals directly from the bridge unless the connector standard and logic levels match the device. Add the appropriate RS-232, RS-485, or other physical-layer transceiver where required, and account for termination, biasing, isolation, and ESD protection in the connector path. Use controlled-impedance routing or short differential connections as appropriate, and keep return paths continuous. The supplied data confirms UART operation to 33 Mbps but does not provide edge-rate or timing tolerances, which must be checked before high-speed signal tuning.
Avoid treating PI7C9X762CLEX or any generic cross-reference result as a drop-in substitute without confirming the suffix definition, package orientation, pin map, electrical limits, and firmware register compatibility. The verified results identify PI7C9X762CLE in a 50-piece tube and list PI7C9X762CLEX separately, but they do not establish that the two are packaging-only variants. Also do not infer that the bridge provides RS-232 or RS-485 physical-layer conversion; it is a UART protocol bridge, and the correct external transceiver remains necessary.
Calculate power availability from the manufacturer datasheet because the verified excerpts describe low operating and sleeping current but provide no numeric current, voltage, or absolute-maximum ratings. Confirm the supported supply range, startup behavior, and sleep-state current before sizing the host rail and battery budget. If multiple rails or sequencing are involved, use a power architecture that keeps every bridge pin within its specified limits during reset and power transitions. Treat the 33 Mbps communication rating as a performance limit, not evidence that the device can operate from an unverified voltage range.
合规信息
The supplied verified excerpts do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable to this interface controller because no automotive qualification is stated.
