Hi,

in the data-sheet of the SLG46880 there is no information on programming the NVM part over the I2C. I could only see page write/erase times on page 14/353.

Could you provide us more information?

正式,这部分不能公关ogrammed over I²C, but seehttps://www.eevblog.com/forum/microcontrollers/using-greenpak-configura…

The data-sheet, page 34, 4 User Programmability states:

  • The SLG46880/81 is a user programmable device with a one time programmable (OTP) memory array that is used to configure the 12 state ASM, logic, and Mixed-Signal circuits.

So how to burn this OTP.

We are already using I2C in devel mode.

Hi,

Thanks for reaching out. To burn the OTP memory, we set PIN5 higher than 5.5V

Kind Regards

Hi Shivani,

so PIN5 is set to ~6 V, and then the usual i2c write sequence will do the job, so writing 2 x 256 bytes to both banks, one after another?
