New SPI & I2C Applications for the Promira Serial Platform
SPI Active - Level 3 Application
The all-new architecture of the SPI Active - Level 3 Application running on the Promira™ Serial Platform provides even faster programming speeds, superior performance, more slave select lines and additional GPIOs.
The Promira Serial Platform with the SPI Active – Level 3 Application supports all multi-I/O SPI devices. Each data transfer burst in Quad I/O mode at 80 MHz is 40x faster compared to the Aardvark™ I2C/SPI Host Adapter. And, there are now 8 available chip selects versus 1 with the Aardvark adapter and 3 with the Cheetah™ SPI Host Adapter.
Updated features include:
Protocols Supported: Single, Dual and Quad I/O SPI
Master Clock Speed: up to 80 MHz
Slave Clock Speed: up to 20 MHz
Chip/Slave Select Lines: 8
Software configurable Slave Select (SS) polarity in master mode
Slave Response: up to 256 bytes per response, variable word length
Multi I/O Memory Programing: EEPROM, Flash, other SPI memory
GPIO(s): up to 16
Voltage Levels: 0.9-3.45, 5 V
Target Power: 2 independent supplies, 1 programmable (0.9-3.45 V), 1 switchable (3.3-5 V), 100 mA each
Connection Types: High Speed USB, Ethernet 10/100/1000
Not to be out done by SPI, Total Phase has also announced the release of yet another I2C Application for the Promira platform – the I2C Active - Level 2 Application.
This new application offers High Speed (HS) mode allowing I2C data transfer 4x faster per burst compared to the Aardvark adapter. The application auto selects to High Speed mode based upon the requested transmit frequency, works with memory, sensor and data conversion products. The latest features include:
Master Clock Speed: up to 3.4 MHz
Slave Clock Speed: up to 3.4 MHz
Slave Response: up to 256 bytes per unique response
No inter-byte delays
HS Memory Programing: EEPROM, other I2C memory
GPIO(s): up to 12
Voltage Levels: 0.9-3.45, 5 V
Target Power: 2 independent supplies, 1 programmable (0.9-3.45 V), 1 switchable (3.3-5 V), 100 mA each
Connection Types: High Speed USB, Ethernet 10/100/1000
