Key Features
Voltage translation 1.2V to 3.3V logic levels
I2C speeds up to 800 kHz supported
SPI and MDIO speeds up to 20 MHz
Optional target device power supply included
Dual target connectors for flexible connections
External breakout headers for custom interfacing
Compatible with all Total Phase instruments
Overview
The board supports I2C communication up to 800 kHz and SPI/MDIO signalling up to 20 MHz, making it suitable for both development and production testing environments. Engineers can optionally supply power to downstream devices at the selected voltage level, eliminating the need for separate power supplies in many applications.
The Level Shifter Board includes dual target connectors, external breakout headers, and configurable voltage selection via jumper settings. Compatible with all Total Phase serial interface tools, this accessory extends the reach of your test equipment to modern low-voltage embedded systems.

Why Engineers Choose The Total Phase Level Shifter Board (TP240610)
Multi-voltage Compatibility
Enables Total Phase tools to work with 1.2V, 1.5V, 1.8V, 2.5V, 3.0V and 3.3V devices seamlessly
Integrated Power Supply
Optional 50mA power output eliminates need for separate target device power supplies
High-Speed Performance
Maintains signal integrity up to 800kHz I2C and 20MHz SPI/MDIO with minimal propagation delay
The Level-Shifter Board allows to your perform level shifting for I2C, SPI, and MDIO signals and supports voltage levels of 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, and 3.3V. It can be used to supply power to downstream devices and transfers I2C signals at a speed of 800 kHz and SPI and MDIO signal at speeds of 20 MHz.
The board has two connectors for connecting to the target interface and two additional connectors to connect an Aardvark™/Cheetah™ Host Adapter and a Beagle™ Protocol Analyser. The board needs to be powered at the Host/Analyser interface by a 5V power supply. This is normally supplied by the Host Adapter or Analyser. The Target interface is powered either from the Target interface itself or from the Host end via a set of jumper selectable voltages.
Engineer Q&A
10 questionsQuestions and Answers
-
Is the Level Shifter Board Bidirectional?
Yes, the board provides true bidirectional level translation, allowing signals to flow in both directions between the Total Phase instrument and target device without requiring direction control pins. -
What Cables Are Included with the Level Shifter Board?
The board comes with a 6-inch 10-pin ribbon cable, a 1.5-inch 10-pin ribbon cable and three configuration jumpers. -
Can I Use the Level Shifter Board as a Signal Pass-through Without Voltage Translation?
Yes, by setting the voltage jumper to 3.3V, the board can pass signals through without level translation whilst still providing signal buffering and isolation. -
What Is the Minimum Voltage Level the Board Can Translate To?
The Level Shifter Board can translate down to 1.2V logic levels, which suits low-power microcontrollers and embedded systems. -
Does the Level Shifter Board Require External Power?
No. The board is powered from the connected Total Phase instrument via the target power feature, which must be enabled in the software. -
Which Total Phase Instruments Are Compatible with the Level Shifter Board?
The Level Shifter Board works with all Total Phase I2C and SPI tools, including:
- Aardvark I2C/SPI Host Adapter
- Beagle I2C/SPI Protocol Analyzer
- Cheetah SPI Host Adapter
- Promira Serial Platform with appropriate applications
-
What Voltage Levels Can the Level Shifter Board Translate To?
The board supports translation to 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, and 3.3V logic levels. Voltage selection is configured via jumper settings or by using the target device's own power supply. -
Can the Level Shifter Board Provide Power to Target Devices?
Yes. The on-board regulator can supply up to 50mA at the selected voltage, enough to power small devices such as flash memory chips or sensors directly. -
What Are the Maximum Communication Speeds Supported?
The Level Shifter Board supports I2C communication up to 800 kHz and SPI/MDIO signalling up to 20 MHz. Actual speeds may vary depending on target device specifications and cable lengths. -
How Do I Connect Multiple Target Devices to the Level Shifter Board?
The board provides two cross-connected target connectors (TARGET1 and TARGET2) plus external breakout headers. Multiple I2C devices can share the same bus, whilst SPI devices require separate chip select lines.
