FT 5000 EVB Hardware Details
5. Connect your external serial EEPROM or flash memory device to a compatible device
programmer. Echelon has tested the Aardvark™ I2C/SPI USB Host Adapter from TotalPhase™
(Part No. TP240141), with the 10-pin split cable from TotalPhase (Part No. TP240212), as one
method for creating this connection (for more information on this adapter, go to the TotalPhase
). The Aardvark has six signal lines:
two for the I
2
C interface (SDA and SCL), and four for the SPI interface (MOSI, MISO, SCL, and
SS).
The I
2
C/SPI interface used by the FT 5000 Smart Transceiver has some pins that are
multifunctional; therefore you must disconnect the external serial memory device using JP1 [see
External Serial Non-Volatile Memory Device Connection (JP1) for more information] and
program each memory device individually. After you disconnect the external serial memory
device, you can use flying leads provided by the 10-pin split cable to connect the Aardvark
programmer to the external serial EEPROM or flash device.
The following figures display the connections you need to make between the Aardvark
programmer and the external memory devices on the FT 5000 EVB for the in-circuit programming
over the SPI and I
2
C interfaces.
