Aspeed Ast2500 Datasheet New Fixed 【Mobile】

The AST2500 features an advanced on-chip PCIe 2D VGA controller. This gives server systems reliable local display capabilities without the added cost and power consumption of a standalone VGA add-on card. Memory Upgrades and System Performance

: Features a dual-core ARM Cortex A7 and advanced 28nm process for improved security (Secure Boot/TrustZone). AST2700 Series

Up to 16-channel 10-bit ADCs track system voltages and temperatures with high precision.

Up to 8 Pulse Width Modulation (PWM) channels for dynamic, closed-loop fan speed control based on thermal profiles. 5. Software and Firmware Ecosystem aspeed ast2500 datasheet new

Dedicate an unbroken ground reference plane directly beneath the AST2500 to shield the analog-to-digital converters (ADCs) from digital switching noise. 5. Firmware Compatibility: OpenBMC and Beyond

Faster speeds when mounting remote ISOs or disk images for OS deployment and server provisioning. I/O Flexibility and Connectivity

The SoC integrates a PCIe graphics-enabled hardware engine capable of local display output and high-performance remote KVM (Keyboard, Video, Mouse) redirection. The AST2500 features an advanced on-chip PCIe 2D

: Features an 800MHz ARM11 processor, providing the computational overhead needed for modern advanced BMC tasks.

Specific I/O highlights detailed in the specifications include:

Acts as the modern LPC replacement interface to communicate with Intel, AMD, and ARM host processors. AST2700 Series Up to 16-channel 10-bit ADCs track

: Incorporates full Error-Correction Code (ECC) options to prevent data corruption within the management stack without incurring additional external component costs. Integrated 2D Graphics and Remote Presence (iKVM)

Multiple independent PWM (Pulse Width Modulation) outputs for precise cooling profiles.

The primary 800 MHz ARM1176JZ-S core handles all BMC management functions, including IPMI command processing, web server hosting (typically a lightweight HTTP/HTTPS stack), KVM session management, and sensor polling. The memory subsystem supports both and DDR4 SDRAM with a 16-bit data width, allowing up to 1GB of addressable memory. This is augmented by 36KB of internal SRAM for low-latency, critical-path code execution.
