Hello everyone,
From asktexas@ti.com I received email I should post this question on the e2e forum so that multiple people could help with this problem.
We have an customer that has a battery powered tracking device(GPS + motion). This device stores its tracking information on an onboard, non-removable (internal) micro-sd card. This tracking device also has an mini-USB port.
These trackers need to be read-out using the mini-usb port on the tracking device. The current tracker has a very slow download speed of the files onboard the SD card inside the tracking device. This slow speed is caused by the microcontroller that is in between the USB port and the micro-SD card. Speed is now several kilobytes/sec. Data goes from SD to MCU to USB now.
We need to improve this download speed without changing the current microcontroller.
Basically, when we download the files from the SD-card, we need to bypass the bottleneck that is caused by the microcontroller. We want to achieve USB2.0 speeds with the new design.
What I could find real quick online was an obsolete part from Maxim Integrated. https://www.maximintegrated.com/en/products/interface/MAX14500.html/tb_tab0
Im not sure if it would work out with that part, but it shows the solution we need.
Does Texas Instruments have a solution to solve this problem? Or can someone help me in the right direction?
Kind regards,
Marc
