P3A1604UK-ARD - Arduino Eval Board for 4-bit Level Translator | NXP
MPN： P3A1604UK-ARD ✓ 啟用中P3A1604UK-ARD 概覽
A dual-supply translating transceiver is an interface IC that allows digital signals referenced to one supply domain (for example a 1.2 V core rail) to communicate with devices in a second domain (for example a 3.3 V I/O rail). Within the signal-chain hierarchy, it belongs to the logic translator family under interface ICs, sitting between level shifters, bus switches, and buffers. The P3A1604UK's auto direction sensing removes the need for a direction-control pin, which simplifies firmware and avoids bus contention in bidirectional links.
Key features of the underlying device include four 1-bit input-output ports (A and B ports), an output enable input (OE), wide supply ranges of VCCA from 0.72 V to 1.98 V and VCCB from 1.62 V to 3.63 V, and support for emerging standards such as I3C alongside legacy I2C and SPI buses. The evaluation board maps these signals onto standard Arduino headers so that any Arduino-form-factor microcontroller board can drive the translator during bench evaluation.
Typical applications validated on this board include interfacing 1.2 V or 1.8 V microcontroller I/O banks to 3.3 V peripherals, translating I3C sensor buses in mobile and IoT designs, and level-shifting SPI flash or display interfaces. Engineers can use the board to verify timing, drive strength, and power sequencing before committing to a custom PCB footprint.
A key design consideration: because the translator is a dual-supply device, the evaluation setup should confirm correct VCCA/VCCB power-up order behavior and OE control with the target controller before tape-out. According to NXP product documentation, the P3A1604UK datasheet (24 pages, 449 kB PDF) covers the full electrical and switching characteristics needed for production design.
This page synthesizes distributor availability data, datasheet-derived specifications, and practical design notes not found on the manufacturer product page alone, providing a single citable reference for the P3A1604UK-ARD evaluation platform.

典型應用
P3A1604UK-ARD 適用於 6 應用s: I3C Sensor Bus Prototyping, Microcontroller Core-to-Peripheral Level Translation, SPI Interface Validation, I2C Bus Isolation Between Voltage Domains, IoT and Mobile Design Reference, Automotive and Industrial Sub-1V Interface Evaluation.
I3C Sensor Bus Prototyping
The P3A1604UK-ARD lets engineers prototype I3C sensor buses where the controller operates at 1.0 V to 1.2 V while legacy targets remain at 1.8 V or 3.3 V. The P3A1604UK's auto direction sensing translates the bidirectional I3C traffic - including both push-pull SDR messages and open-drain CCC broadcasts - without any DIR pin or firmware intervention. By stacking the board on an Arduino-form controller, engineers can validate in-band interrupts, dynamic addressing, and bus timing on a bench within minutes. The wide VCCA range down to 0.72 V covers next-generation sub-1 V process nodes. Quantified benefit: four channels translate two complete I3C buses (SDA/SCL pairs), enabling side-by-side controller and target domain tests on one board before committing to PCB layout.

Microcontroller Core-to-Peripheral Level Translation
Modern microcontrollers run core logic at 1.1 V to 1.2 V while external flash, displays, and sensors still require 1.8 V or 3.3 V signaling. The P3A1604UK-ARD demonstrates how the P3A1604UK bridges these domains with VCCA from 0.72 V to 1.98 V and VCCB from 1.62 V to 3.63 V. Engineers wire the four A/B ports to the MCU's low-voltage SPI or GPIO bank and the B side to a 3.3 V peripheral, then verify drive strength, propagation delay, and power sequencing on the bench. The output enable input permits safe tri-stating during MCU reset. Quantified benefit: validating translation behavior on the eval board avoids PCB respins caused by mis-sequenced dual-rail designs, a frequent source of latch-up in mixed-voltage systems.
推薦
SPI Interface Validation
SPI is a push-pull, controller-driven bus, and the P3A1604UK-ARD allows SPI clock and data lines to be translated between a low-voltage controller and a 3.3 V target such as flash memory or an SD card interface. According to NXP, the board supports SPI connections in both controller and target roles. Because SPI clock integrity is timing-critical, engineers can use the evaluation board with an oscilloscope to measure channel-to-channel skew and rise/fall times across the translator at the target system clock rate. Quantified benefit: the 4-bit width covers a full SPI 4-wire link (SCLK, MOSI, MISO, CS) in a single device, so one P3A1604UK replaces the two single/dual-channel translators a discrete design would otherwise require.
推薦
I2C Bus Isolation Between Voltage Domains
I2C buses frequently mix a 1.8 V main controller with 3.3 V EEPROMs, RTCs, and sensors. The P3A1604UK-ARD demonstrates level translation on both SDA and SCL using two of the four A/B channels, leaving two channels spare for interrupt or enable signals in the same domains. The P3A1604UK's auto direction sensing handles I2C's open-drain bidirectional traffic natively - the controller never arbitrates direction, and clock stretching passes through correctly. Engineers can verify pull-up sizing on each domain independently, since each side references its own supply (VCCA or VCCB). Quantified benefit: the OE input allows the entire bus to be released during controller reset, preventing partial-address glitches that lock up slave devices in multi-controller I2C systems.
推薦
IoT and Mobile Design Reference
Battery-powered IoT and mobile products concentrate multiple voltage domains - a 0.9 V to 1.2 V application processor domain, a 1.8 V memory domain, and 3.3 V sensor or radio domains. The P3A1604UK-ARD serves as a reference bench setup for these systems, proving that the P3A1604UK maintains signal integrity across the full VCCA range of 0.72 V to 1.98 V, including brownout regions where batteries sag. Engineers can emulate battery droop with a bench supply and observe translator behavior at the VCCA minimum. Quantified benefit: confirming operation down to 0.72 V on the evaluation board derisks end-of-discharge behavior in portable designs, where many level shifters lose specified performance and communications errors appear only in the field.
推薦
Automotive and Industrial Sub-1V Interface Evaluation
Automotive MCUs and industrial SoCs increasingly run on sub-1 V core processes while communicating with 3.3 V transceivers, and NXP's own SPC5 and S12 families illustrate the domain-mixing challenge the P3A1604UK-ARD helps solve. Engineers evaluating next-generation interface cards can use the board to characterize translator behavior with realistic bus loading - longer traces, connector stubs, and ESD protection capacitance - before finalizing a production footprint. The wide VCCB range up to 3.63 V tolerates 24 V-system transients clamped to 3.3 V rails with margin. Quantified benefit: bench data captured through the evaluation board (propagation delay versus load capacitance, VCCA undervoltage behavior) feeds directly into timing budgets for the production schematic.

設計說明
The P3A1604UK is a dual-supply device: VCCA (0.72 V to 1.98 V) and VCCB (1.62 V to 3.63 V) must both be present for valid translation. When using the P3A1604UK-ARD, power the A-side domain from a bench supply or the host Arduino's low-voltage rail and the B-side from a 3.3 V rail, and verify power-up sequencing behavior on the evaluation board before designing the production power tree. The OE input should be held low until both rails are stable to prevent undefined output levels during startup.
For I3C and I2C evaluation, size pull-up resistors independently on each side of the translator: the A-side pull-ups tie to VCCA and the B-side pull-ups tie to VCCB. During evaluation with the P3A1604UK-ARD, start with approximately 2.2 kOhm to 4.7 kOhm pull-ups on a 100 kHz-400 kHz I2C bus and reduce resistance only as needed for rise-time compliance at higher speeds. Observe both domains with a scope to confirm the auto direction sensing switches cleanly on open-drain transitions.
Do not confuse the evaluation board with the IC: production designs must reference the P3A1604UK datasheet (24-page PDF from NXP) for the device pinout - documented as transparent top view, terminal side down - and full electrical characteristics. A frequent mistake is copying the eval board's wiring into a schematic without honoring the IC's actual pin arrangement. Also remember that only 4 bits are available: an SPI link consumes all four channels, while an I2C link leaves two channels for interrupts or additional signals.
