Rockbox mail archiveSubject: New cpu docsNew cpu docs
From: Björn Stenberg <bjorn_at_haxx.se>
Date: Fri, 21 Dec 2001 00:25:56 +0100 (CET) I found some updated documents on the SH-1 cpu and put them up on the docs page. I also noticed the "product line" table in section 1.2. It gives a few hints about the strange numbers printed on the CPU chips. Judging from the closest match I found in the table (HD6437034AVX12), HD6437034R14X probably means: - HD643: has masked ROM - 7034: is an SH-7034 AVX12 means: - A: Masked ROM? - V: 3.3V - X: Package typ TQFP (TFP-120) - 12: 2-12.5 MHz frequency range R14X is not listed in the product line. Guessing: - R: ??? - 14: 2-14 MHz freq range? - X: Package typ TQFP (TFP-120) Better guesses, anyone? /Björn Received on 2001-12-21 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
