Aspeed Ast2500 | Datasheet [2021]

: Co-Processor (ARM7) for background management tasks, lowering primary CPU utilization. Memory Support and Interfaces

The AST2500 contains a but not a PHY (Physical Layer Transceiver). The datasheet specifies:

Features integrated Gigabit Ethernet , USB, SD/MMC, SPI, and I2C controllers for robust input/output handling. Aspeed Ast2500 Datasheet

When you search for the "Aspeed AST2500 Datasheet," you are likely looking for either the Hardware Reference Manual (pinout/electrical) or the Technical Reference Manual (register level). Aspeed distinguishes these strictly. Most engineers need the Hardware one for board schematics.

Understanding the technical specifications, architectural layout, and hardware interfaces in the AST2500 datasheet is essential for hardware engineers, firmware developers (working with OpenBMC or AMI MegaRAC), and systems architects. 1. Architectural Overview and Core Processor When you search for the "Aspeed AST2500 Datasheet,"

According to Section 7.2 of the datasheet, 3.3V must ramp last.

Features an 800MHz ARM11 (specifically ARM1176JZS) CPU. feature-rich Linux-based BMC firmware (e.g.

: Addresses up to 1 GB of RAM to support modern, feature-rich Linux-based BMC firmware (e.g., OpenBMC).

The chip acts as a bridge between the host system and the peripheral management ecosystem.
