Missing SRAM layout of LPC546xx 136KB RAM version in doc

LPC546XX has 136KB RAM and 256KB flash version, but I cannot find the 136KB SRAM memory map in the reference manual, which all describe RAM as 200KB.

My question is which is the SRAM layout for 136KB RAM version of LPC546xx (e.g. LPC54605J256ET180)?

Hi,

SRAM banks starts from 0x20000000 with size 0x18000(96K)

SRAMX starts from 0x4000000 with size 0x8000(32K)

USB RAM starts from 0x40100000 with size 0x2000 (8K)

 

Sum - 136KB

 


Have a great day,
Sol
