Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM MPU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3892CCYGA120 | No SGX530 graphics engine; identical CPU, memory, and peripheral configuration otherwise | Not suitable for GPU-accelerated UI or video composition; lower thermal envelope and BOM cost | Select when 2D GUI or headless operation suffices and graphics acceleration is unnecessary |
| AM4379BZDNA100 | Newer 1-GHz ARM Cortex-A9 core, PRU-ICSS for real-time I/O, no HDMI or SGX530; supports industrial temp range | Better real-time determinism and extended temperature support; lacks HDMI output and 3D graphics | Prefer for deterministic industrial control with EtherCAT/PROFINET, where HDMI and GPU are not required |
Compared with AM3892CCYGA120, AM3894CCYGA120 adds critical 3D graphics and HDMI 1.3 output for rich visual interfaces; versus AM4379BZDNA100, it trades PRU-based real-time I/O and extended temperature for higher clock speed, mature HDMI/HDCP stack, and proven SGX530 driver ecosystem.

FAQ
What is the maximum operating frequency of the AM3894CCYGA120 CPU core?
The AM3894CCYGA120 features an ARM Cortex-A8 core rated for up to 1.20 GHz under specified thermal and voltage conditions. This frequency is confirmed in the SPRS681G datasheet revision March 2015 and applies to the CYG package variant. Operation above 1.20 GHz is not supported or characterized. The AM3894CCYGA120 achieves this speed using adaptive voltage scaling managed by SmartReflex Level 2 circuitry.
Does the AM3894CCYGA120 include an integrated graphics processing unit?
Yes, the AM3894CCYGA120 integrates the PowerVR SGX530 3D graphics engine - delivering up to 30 million triangles per second and supporting OpenGL ES 1.1/2.0, OpenVG 1.1, and Direct3D Mobile. This GPU is exclusive to the AM3894 variant; the AM3892 does not include it. The AM3894CCYGA120 uses the SGX530 to accelerate UI rendering, video compositing, and 2D/3D graphics workloads offloaded from the Cortex-A8 CPU.
What package type and ball count does the AM3894CCYGA120 use?
The AM3894CCYGA120 is packaged in a 1031-ball Fine-Pitch Chip Array Ball Grid Array (FCBGA) with dimensions of 25.0 mm × 25.0 mm and a 0.65-mm ball pitch. It employs Via Channel™ technology to enable 0.8-mm PCB trace routing, reducing layer count and cost. This package is identical across all AM3894CYG variants, including AM3894CCYGA120, and is documented in TI's SPRS681G datasheet Section 11.1.
Can the AM3894CCYGA120 operate as a PCIe root complex?
Yes, the AM3894CCYGA120 supports PCIe 2.0 in configurable root complex or endpoint mode. Its single PCIe port operates with two 5.0 GT/s lanes and includes an integrated PHY. In root complex mode, the AM3894CCYGA120 can enumerate and manage downstream devices such as FPGAs, NVMe SSDs, or network controllers - a capability verified in TI's AM389x Technical Reference Manual and used in reference designs like the AM3894 EVM.
What video output interfaces are supported by the AM3894CCYGA120?
The AM3894CCYGA120 supports multiple video outputs via its HDVPSS: analog SD/HD composite and component (YPbPr), digital HDMI 1.3 with HDCP encryption (up to 165-MHz pixel clock), and three programmable graphics layers. HDMI output is fully integrated with PHY and supports 1080p60 resolution. The AM3894CCYGA120 does not support DisplayPort or MIPI DSI; HDMI and analog DACs are its sole standardized video output paths.
