Ultra-low-power SRAM (ULP SRAM)#

ULP SRAM is used when the device input is in ultra-low-power mode. SiWG917 has different power domains that are explained in the datasheet. ULP implements multi-port SRAM memory.

Features:

  • Total 8 KB memory

  • Total memory divided into four 2K regions.

Base addresses for the four 2K banks are as follows (these are Bytewise addresses):

  • 1st 2K: 2406_0000

  • 2nd 2K: 2406_0800

  • 3rd 2K: 2406_1000

  • 4th 2K: 2406_1800
