1 Actual system bus speed may vary as a function of capacitance.
2 The quoted values are intra-byte speeds. Please refer to the datasheet for timing restrictions.
3 Customers have successfully over-clocked the Cheetah SPI adapter to 50 MHz.
4 Actual SPI capture performance is dependent on CPU speed and SPI bus throughput. 24 MHz SPI capture has been tested for typical applications (e.g., captures of a few hundred SPI packets). Depending on user configuration, the maximum achievable capture throughput for continuous streaming applications may be less than 24 MHz.
5 Refers to SPI Active Mode, not SPI Analysis.
6 Available for Active use, coming soon to Analysis Applications.

FAQ

Flash programming in production can be slow, reducing efficiency in large-scale manufacturing. The Cheetah SPI Host Adapter and the Promira Serial Platform support higher SPI clock speeds—up to 40 MHz and 80 MHz respectively—accelerating data transfer during large memory writes. Our host adapters also can perform gang programming for high-volume programming applications. Learn more: Programming Flash Memory on Production Line.
SPI timing issues, such as bit misalignment or unexpected delays, can cause communication failures or data corruption. The Beagle I2C/SPI Protocol Analyzer with Data Center Software provides a Timing pane that overlays bit-level diagrams of the MOSI and MISO lines. When a Transaction record is selected, both lines appear overlapped, allowing you to visually inspect timing relationships between transmitted and received data at the bit level with nanosecond precision. Learn more: Viewing SPI Timing Details using a Protocol Analyzer.
The Promira Serial Platform, when configured with the appropriate licensed applications, provides support for Dual and Quad SPI (QSPI) programming. Paired with our Flash Center Software, which includes native support for a wide range of QSPI chips from major manufacturers, you can easily program, read, verify, and erase memory devices in just a few steps. Follow the steps here.
The Promira Serial Platform features built-in voltage level shifting, making it easy to interface with SPI memory devices that operate at lower voltages. Users can seamlessly select voltage levels ranging from 0.9 V to 3.45 V, ensuring compatibility with a wide range of lower voltage devices without needing external level shifters. Learn more about the Promira platform’s native support for level-shifting.
During development, validating both SPI master and slave device behavior is crucial for reliable communication. Host adapters like the Promira Serial Platform and Aardvark I2C/SPI Host Adapter are invaluable tools because they can emulate SPI masters—sending controlled commands to test SPI slave devices—or emulate SPI slaves to validate master operations using single slave responses. For even deeper debugging, the Beagle I2C/SPI Protocol Analyzer captures timing and byte-level data exchanges, helping pinpoint where communication issues occur. Learn more about using these tools to validate SPI devices during development.
When using Total Phase tools like Control Center Serial Software or Flash Center Software for active SPI communication, you can configure the SPI mode (0 through 3) to set the appropriate clock polarity and phase for your device. These settings determine how and when data is captured and propagated relative to the clock signal, ensuring compatibility with your device’s SPI timing requirements. In addition to SPI mode, the software allows you to set the bit order—choosing whether the most significant bit (MSB) or least significant bit (LSB) is transmitted first—and to define the polarity of the slave select (SS) line, which is typically set to active low. Together, these options provide the flexibility needed to match the communication settings specified in your device’s datasheet. Find out more here.
Using the Aardvark I2C/SPI Host Adapter, Cheetah SPI Host Adapter, or Promira Serial Platform with Flash Center Software, you can easily program a single sector by loading a file that targets only that sector. Flash Center will erase, program, and verify just the specified area, leaving the rest of the memory untouched. Learn more about this process here:Programming a Single Sector of an SPI Flash.
Reading the Device ID is a common way to verify that an SPI flash chip is properly connected and responding. With a Total Phase SPI host adapter and Control Center Software/API, you can send a standard Read Identification command based on the Flash chip’s datasheet. The chip will respond with a series of bytes identifying the manufacturer and device type. Find out how to do the steps here.
For engineers needing to program firmware or other data onto flash chips—whether in-system or on the production line—Total Phase’s line of host adapters, paired with Flash Center Software or the API for custom applications, enable fast and efficient read, write, verify, and erase operations in just seconds. Find the right host adapter for your programming requirements in our Guide to Fast Serial Flash and EEPROM Programming.
Remote control of SPI systems is essential for distributed teams and automated testing setups. The Promira Serial Platform's Ethernet connectivity enables engineers to program and test devices over a network, providing seamless remote access and control. Learn more about the Remote Capabilities of the Promira Serial Platform Using Ethernet.
If you need to automate SPI system validation and regression testing, a host adapter like the Promira Serial Platform can send predefined command sequences via batch scripting. It supports command queueing—up to 127 queues with 255 commands each—and can run them synchronously or asynchronously through the Promira Software API, enabling efficient, repeatable testing after hardware or firmware updates, as well as stress testing and full system validation. Learn more here: How to Automate SPI System Validation and Regression Testing in Embedded Systems.
