TP280121) is a high-speed USB to SPI adapter, capable of communicating at over 40 MHz. It was specifically designed to communicate with SPI Flash memories, and is used to develop, debug and program systems that use them.<\/p>\n<p>Connected to a computer, the Cheetah acts as an <strong>SPI master<\/strong>. Its pipelined architecture allows gapless shifting, and its transaction queue maximizes throughput. You stay in control of timing, with precise delays you can insert yourself.<\/p>\n<p>Several free software tools come with it, depending on use: Flash Center for memory programming, Control Center Serial for exchanges, and an API to integrate the adapter into your own tools.<\/p>\n<h2>Highlights<\/h2>\n<ul>\n<li><strong>High speed:<\/strong> SPI master up to 40+ MHz.<\/li>\n<li><strong>Optimized throughput:<\/strong> transaction queuing and pipelined architecture for gapless shifting.<\/li>\n<li><strong>Controlled timing:<\/strong> precise, user-insertable delays.<\/li>\n<li><strong>Multiple devices:<\/strong> up to 3 slave selects.<\/li>\n<li><strong>Programming:<\/strong> Flash and EEPROM memories, in-system or stand-alone.<\/li>\n<\/ul>\n<h2>Technical specifications<\/h2>\n<ul>\n<li><strong>Manufacturer reference:<\/strong> TP280121<\/li>\n<li><strong>Rate:<\/strong> SPI master from 0.1 MHz to 40+ MHz<\/li>\n<li><strong>Host interface:<\/strong> USB 2.0, Standard-B receptacle<\/li>\n<li><strong>Target-side connector:<\/strong> 2 x 5 female IDC, 2.54 mm pitch<\/li>\n<li><strong>Target-side cable:<\/strong> 10-pin ribbon cable, 1.27 mm pitch, 25.4 mm long<\/li>\n<li><strong>SPI pinout:<\/strong> SS2 (1), SS3 (3), MISO (5), SCLK (7), MOSI (8), SS1 (9)<\/li>\n<li><strong>Power supply :<\/strong> GND (2, 10), NC\/+5 V (4, 6)<\/li>\n<li><strong>Electrical characteristics:<\/strong> target power +5 V, 25 mA max; signals 3.3 V, 10 mA<\/li>\n<li><strong>Operating temperature :<\/strong> 10 to 35 \u00b0C<\/li>\n<li><strong>Dimensions :<\/strong> 55.6 x 22.2 x 89 mm<\/li>\n<li><strong>Weight :<\/strong> 64 g<\/li>\n<li><strong>Standards and quality:<\/strong> CE, RoHS; ISO 9001, ISO 13485, AS9100C certified manufacturing; made in the USA<\/li>\n<\/ul>\n<h2>Supported software and systems<\/h2>\n<ul>\n<li><strong>Software to download:<\/strong> Flash Center, Control Center Serial, Cheetah Software API, Cheetah LabVIEW driver, USB drivers (required on Windows and Linux)<\/li>\n<li><strong>Operating systems:<\/strong> Windows 7, 10, 11 and later; Linux (Red Hat, SuSE, Ubuntu, Fedora); macOS 13 and later<\/li>\n<li><strong>Analysis computer, minimum configuration:<\/strong> Intel or AMD processor at 2 GHz or faster, 1 GB RAM (32-bit) or 2 GB (64-bit), 2 GB disk space, full-speed USB port, 1024 x 768 display or higher<\/li>\n<\/ul>\n<h2>Use cases<\/h2>\n<ul>\n<li><strong>SPI memory programming:<\/strong> writing Flash and EEPROM, on or off the board.<\/li>\n<li><strong>Embedded development:<\/strong> simulating an SPI master to test a device.<\/li>\n<li><strong>Test benches:<\/strong> automating SPI exchanges with the API.<\/li>\n<\/ul>\n<h2>Compatibility and what you need to know<\/h2>\n<p>The Cheetah works as an SPI master: it does not support I2C and does not serve as a bus analyzer. To observe traffic without intervening, look instead at the<a href=\"https:\/\/monraspberry.com\/en\/product\/total-phase-beagle-i2c-spi\/\">Beagle I2C\/SPI analyzer<\/a> (ref. TP320121). Signals are 3.3 V: check that this suits your target.<\/p>\n<h2>Box contents<\/h2>\n<ul>\n<li>1 Cheetah SPI Host Adapter<\/li>\n<li>1 USB-A to USB-B cable, 6 ft (about 1.8 m)<\/li>\n<\/ul>\n<p>Manufacturer warranty: one year.

It handles I2C and SPI, but in SPI it stops at 8 MHz as a master. The Cheetah is dedicated to SPI and exceeds 40 MHz.<\/p>\n<h3>Does the Cheetah analyze SPI traffic?<\/h3>\n<p>No, it controls the bus as a master. To observe without intervening, you need an analyzer such as the <a href=\"https:\/\/monraspberry.com\/en\/product\/total-phase-beagle-i2c-spi\/\">Beagle I2C\/SPI<\/a>.<\/p>\n<h3>Can I install the software on a Raspberry Pi?<\/h3>\n<p>Total Phase specifies a computer with an Intel or AMD processor as the minimum configuration and does not list the Raspberry Pi among supported systems.
