I2C/SPI Exerciser and Protocol Analyzer

I2C Protocol Analyzer and SPI Protocol Analyzer (PGY-I2C/SPI-EX-PD) are the Protocol Analyzers with multiple features to capture and debug communication between host and design under test. PGY-I2C/SPI-EX-PD is the leading instrument that enables the design and test engineers to test the respective I2C or SPI designs for its specifications by configuring the PGY-I2C/SPI-EX-PD as Master/Slave, generating I2C/SPI traffic and decoding the I2C/SPI protocol decode packets


I2C/SPI Exerciser and Protocol Analyzer

I2C is a two-wire interface to connect low speed devices like micro-controllers, EEPROM’s, A/D & D/A converters, I/O interfaces, and other small peripherals in embedded systems. I2C bus is used by many IC’s and is simple to implement. Any microcontroller can communicate with I2C buses. I2C bus can communicate in slow devices and can also use high speed modes to transfer large amounts of data.

SPI is one of the widely used interfaces between micro-controller and peripheral IC’s such as sensors, ADC’s, DAC’s, shift registers, SRAM, and others. SPI is synchronous, full-duplex master-slave based interface. Both master and slave can transmit data at the same time. The SPI interface can be a 3 wire or 4-wire.

PGY-I2C/SPI-EX-PD is the leading instrument that enables the design and test engineers to test the respective I2C or SPI designs for its specifications by configuring PGY-I2C/SPI-EX-PD as master/slave, generating I2C/SPI traffic and decoding I2C/SPI Protocol decode packets.
