Aspeed Ast2500 Datasheet New May 2026
If you have an AST2500 on your bench and it isn't working, the "new" datasheet likely has the answer.
The original datasheet claimed H.264 encoding. The new datasheet reveals support for multi-stream compression . You can now encode one stream for KVM (low bandwidth) and another for local recording simultaneously. The register set for VE_OFFSET_CTRL has been expanded to handle two logical channels.
Does the new datasheet hint at an AST2500+? Indirectly, yes. ASPEED has confirmed via the new datasheet's "Ordering Information" section that the (active) and AST2500L-A2 (industrial temp) are the final silicon steppings. No A3 is expected. aspeed ast2500 datasheet new
The "new" AST2500 datasheet is interesting because it frequently references the AST2600. Here is how the chips differ according to the latest comparative tables:
A warning to those searching for "aspeed ast2500 datasheet new": Many third-party "datasheet aggregate" sites host revision 1.01 from 2016 masquerading as new documents. If you have an AST2500 on your bench
"SPI flash corruption during Write Protect toggle." Solution (New Sheet): The new timing diagram shows that the WP# pin has a 10ns minimum hold time after CS# rises. Most legacy drivers set 0ns; this causes corruption in high-temperature environments.
The AST2500 includes an ECC-enabled SPI flash controller. However, the original documentation was ambiguous. The new revision provides explicit code examples for initializing ECC regions for the boot loader. Failure to follow the "new" sequence results in a 30% chance of boot failure after power cycling due to "Flash Uncorrectable Error" flags. You can now encode one stream for KVM
