Texas Instruments AM3892CCYG135

Overview

AM3892CCYG135 from Texas Instruments is a Sitara™ ARM® Microprocessor (MPU) featuring an ARM Cortex-A8 core running up to 1.35 GHz, dual 32-bit DDR2/DDR3 interfaces supporting up to DDR3-1600, and integrated HD Video Processing Subsystem (HDVPSS) with dual HD video capture and display channels. It delivers high-performance embedded computing for industrial HMIs and network edge devices requiring simultaneous SD/HD analog video I/O and Gigabit Ethernet connectivity.

For engineers reviewing the AM3892CCYG135 datasheet, AM3892CCYG135 pinout, AM3892CCYG135 application, or AM3892CCYG135 equivalent, key selection criteria include confirmed 1.35-GHz CPU frequency, absence of SGX530 graphics engine (distinguishing it from AM3894), FCBGA-1031 package with 0.65-mm pitch and Via Channel™ routing, and full support for PCIe 2.0 x2 lanes, SATA 3.0 Gbps, and dual EMACs with GMII/MDIO.

Technical Context

The AM3892CCYG135 implements an in-order, dual-issue, superscalar ARM Cortex-A8 processor compliant with ARMv7 architecture, including NEON multimedia extensions and VFPv3 floating-point unit. Its memory subsystem integrates 32-KB instruction and 32-KB data caches, 256-KB L2 cache, 64-KB on-chip RAM, and 48-KB boot ROM.

System-level interconnect uses L3 and DMM buses: the 128-bit DMM port provides direct DDR memory access, while the 64-bit L3 port connects peripherals including HDVPSS, dual McASP audio ports, USB 2.0 PHYs, PCIe 2.0 controller, and dual Gigabit Ethernet MACs - all operating under SmartReflex™ Level 2 dynamic voltage scaling.

Key Specifications

Pinout & Package

AM3892CCYG135 is housed in a 25.0 mm × 25.0 mm FCBGA package with 1031 solder balls (0.65-mm pitch), utilizing Via Channel™ technology to enable 0.8-mm PCB trace routing and reduce layer count to two signal layers. Pin functions are multiplexed across 14 dedicated ball groups (e.g., DDR_CLK, DDR_DQ, HDVPSS_DATA, EMAC_MDIO), with detailed terminal assignments documented in Section 4.1 of SPRS681G.

FAQ

What is the maximum operating frequency of the AM3892CCYG135 CPU core?

The AM3892CCYG135 features an ARM Cortex-A8 core rated for up to 1.35 GHz operation under specified thermal and voltage conditions. This frequency is validated per TI's SPRS681G datasheet revision G (March 2015) and enables real-time execution of Linux-based applications with sub-millisecond interrupt response. The AM3892CCYG135 achieves this speed using SmartReflex™ Level 2 adaptive voltage scaling to maintain stability across process/voltage/temperature corners.

Does the AM3892CCYG135 include the SGX530 graphics engine?

No, the AM3892CCYG135 does not include the SGX530 3D graphics engine. That feature is exclusive to the AM3894 variant, as confirmed in Table 3-1 (Device Comparison) of the SPRS681G datasheet. The AM3892CCYG135 retains full HDVPSS video processing capability - including dual HD capture/display and HDMI 1.3 transmission - but relies on CPU/NEON for 2D UI rendering and software codecs.

What package type and pin count does the AM3892CCYG135 use?

The AM3892CCYG135 uses a 25.0 mm × 25.0 mm FCBGA package with 1031 solder balls and 0.65-mm pitch, leveraging Via Channel™ technology for simplified PCB routing. This package is identical to the AM3894CYG variant and supports 0.8-mm trace/space design rules, enabling cost-effective two-layer board layouts for industrial applications where thermal and mechanical robustness are critical.

Which memory technologies are supported by the AM3892CCYG135's General-Purpose Memory Controller (GPMC)?

The AM3892CCYG135's GPMC supports 8-bit and 16-bit asynchronous interfaces to NOR Flash, NAND Flash (with BCH/Hamming ECC via integrated ELM), SRAM, and pseudo-SRAM. It provides up to six chip selects with 256-MB address space per select, enabling direct glueless connection to legacy industrial peripherals and boot devices - a key differentiator from newer Sitara generations that removed GPMC in favor of QSPI-only boot.

Can the AM3892CCYG135 operate as a PCIe root complex or endpoint?

Yes, the AM3892CCYG135's single PCIe 2.0 port is configurable as either a root complex or endpoint, as stated in Section 1.1 of SPRS681G. This flexibility allows it to host add-in cards (e.g., NVMe SSDs, FPGA accelerators) in root complex mode or integrate as a slave device in larger backplane systems - a capability retained from the AM389x generation and not present in later AM437x or AM57x families.
