OTP Memory in FXSL9xxxx Dual Channel Intertial Sensor

[akilaawantha]

I'm referring the data sheet of the FXLS9xxxx Dual channel inertial sensor. There is chapter called Functional description (Chapter 11) which explain the memory of the sensor. It contents something called Memory Type codes which is like a key to identify the type of the registers that we are looking at. It is as follows

Memory Type Codes
R - Readable Register with No OTP
F – User Readable Register with OTP
UF0 – One Time User Programmable OTP Location Region 0
UF1 – One Time User Programmable OTP Location Region 1
UF2 – One Time User Programmable OTP Location Region 2
R/W – User Writable Register

I'm new to these kinda stuff. Can someone explain what are the meaning of those memory code (Specially like F - User Readable Register with OTP).

Thanks

Hi Akila,

These codes are used to describe the characteristics of different memory locations or registers within the FXLS9xxxx. Let's break down what each code means

R - Readable Register with No OTP:

This type of register is readable, meaning you can retrieve data from it. It does not have OTP (One-Time Programmable) capabilities. OTP means that the register's value can only be programmed once and cannot be changed after that.

F - User Readable Register with OTP:

This register is readable, like the "R" type. It also has OTP capabilities, which means it can be programmed, but once programmed, its value becomes permanent and cannot be changed.

UF0, UF1, UF2 - One Time User Programmable OTP Location Regions 0, 1, 2:

These are registers that are part of different One-Time User Programmable OTP regions.

R/W - User Writable Register:

This type of register is both readable and writable by the user. You can read data from it, and you can also write new data into it as needed.

BR, Tomas

It is much appreciated that you answered my question. Now all are clear. I'll ask related question if I get confusion about this. Thank you very much.
