In KL81 Reference manual (KL82P121M72SF0RM.pdf), section 4.1.2 (Page 77) states "

4.1.2 Flash memory sizes
The devices covered in this document contain:
• 1 block 128 KB of program flash consisting of 4 KB sectors"

while in the same reference manual, section 34.2.1.1 (page 710) states

" 34.2.1.1 Program Flash Memory Features
• Sector size of 2 KB
• Program flash protection scheme prevents accidental program or erase of stored data
• Program flash access control scheme prevents unauthorized access to selected code
segments
• Automated, built-in, program and erase algorithms with verify"

Which is the correct sector size I should refer to for KL81?

Hi Yi Yang,

It's the document error, the sector size should be 2KB, not 4KB.

Wish it helps you!

Have a great day,
Kerry
