1.3.4 External Memory Connection
The ANTC782 has ANT-FS Client functionality embedded directly on the module This includes the over the air ANT-
FS protocol extension and the required file system utilities to manage stored data in non-volatile storage. This
allows the user to connect an EEPROM directly to the ANTC782 module. Raw files can be sent and managed by
the ANTC782 and downloaded over ANT-FS as desired. The diagram below depicts how to connect an external
EEPROM to the ANTC782. The connection is SPI. Please note that only EEPROM (not flash) is support.
The file system and ANT-FS protocol are managed by using an extended version of the ANT/Host serial protocol.
For complete details on how to use this protocol please consult the ANT document “FS_ANTFS Serial Message”.
The extended Host/ANT interface uses a 2 byte message id to identify FS and ANT-FS specific messages. The
packet structure is detailed below.
1.4 Mounting Guideline
Refer to the recommended footprint drawing in section 4. (the drawing is to be added)
To connect to M5IB type of the C7 module, the mating socket is Molex 52991-0208.
1.5 Reflow Guideline
ANTC7M4IB module is rated at moisture sensitive level 3 (MSL=3). To handle and Use these modules, please
follow the standard IPC/JEDEC J-STD-033B.1, “Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive
Surface Mount Devices”.
To reflow, it is recommended that the peak solder joint/pad temperatures NOT exceeding 240ºC. If possible, pre-
heat the assembly within the oven profile for ~30 seconds at ~150 ºC. Follow the solder paste manufacturer’s
recommendations, especially regarding temperature ramp rate and the time above liquidus.
1.6 Pick-n-Place
ANTC7M4IB module has the package option of 500 modules on a JEDEC standard 13” reel to facilitate machine
pick and place. Please refer to section 4 for tape and reel dimensions (the drawing is to be added).
