Texas Instruments TMS320DM8167SCYG

Overview

TMS320DM8167SCYG from Texas Instruments is a high-performance DaVinci digital media processor integrating an ARM Cortex-A8 RISC CPU (up to 1.2 GHz), a C674x floating-point DSP core (up to 1 GHz), and three HDVICP2 video coprocessors. It delivers up to 8000 MIPS and 6000 MFLOPS, supports dual DDR2/DDR3 interfaces (up to DDR3-1600), and targets real-time HD video infrastructure applications including transcoding and security systems.

For engineers reviewing the TMS320DM8167SCYG datasheet, TMS320DM8167SCYG pinout, TMS320DM8167SCYG application, or TMS320DM8167SCYG equivalent, key selection criteria include HDVICP2 count, absence of SGX530 graphics, DDR3-1600 support, PCIe 2.0 x2 lane capability, and dual Gigabit Ethernet MACs with GMII/MDIO.

Technical Context

The TMS320DM8167SCYG implements a heterogeneous dual-core architecture: the ARM Cortex-A8 handles OS execution, peripheral control, and system management using 32KB I-cache, 32KB D-cache, and 256KB L2 cache, while the C674x DSP executes computationally intensive video/audio algorithms with IEEE 754 SP/DP floating-point support and VLIW parallelism. Both cores share access to 512KB on-chip RAM and are coordinated via a System MMU for unified memory mapping.

Its media subsystem centers on three independent HDVICP2 engines-each capable of 1080p60 H.264 encode or decode-and the HDVPSS, which manages dual 165-MHz HD capture/display channels, HDMI 1.3 transmitter with HDCP, and simultaneous SD/HD analog output. The device lacks the SGX530 3D engine found only in the DM8168 variant.

FAQ

What is the maximum operating frequency of the ARM Cortex-A8 core in the TMS320DM8167SCYG?

The TMS320DM8167SCYG ARM Cortex-A8 core operates at up to 1.20 GHz, as confirmed in the SPRS614F datasheet revision March 2015. This frequency enables robust Linux kernel execution and real-time scheduling for multi-threaded video pipeline tasks. The TMS320DM8167SCYG achieves this speed under specified thermal and voltage conditions (CVDD = 0.85–1.05 V) with SmartReflex Level 2 power management active.

Does the TMS320DM8167SCYG include the SGX530 graphics engine?

No, the TMS320DM8167SCYG does not include the SGX530 3D graphics engine. According to Table 3-1 in the SPRS614F datasheet, SGX530 is available only on the TMS320DM8168 device. The TMS320DM8167SCYG shares identical ARM, DSP, HDVICP2, DDR, and peripheral specifications with the DM8168 but omits SGX530 to reduce cost and power consumption.

How many HDVICP2 video coprocessors are integrated into the TMS320DM8167SCYG?

The TMS320DM8167SCYG integrates three HDVICP2 high-definition video and imaging coprocessors, as explicitly stated in Section 1.1 Features and Figure 1-1 of the SPRS614F datasheet. Each HDVICP2 engine supports independent 1080p60 H.264 encode or decode, enabling concurrent multi-stream video processing without loading the ARM or DSP cores.

What memory technologies does the TMS320DM8167SCYG support via its integrated controllers?

The TMS320DM8167SCYG supports DDR2-800 and DDR3-1600 via dual 32-bit interfaces, plus asynchronous NOR/NAND Flash, SRAM, and pseudo-SRAM through its General-Purpose Memory Controller (GPMC). The DDR3 interface supports up to 2GB total address space with dynamic memory manager (DMM) optimization for tiled 2D block access-critical for video frame buffering in the TMS320DM8167SCYG.

Is the TMS320DM8167SCYG pin-compatible with other devices in the DM816x family?

Yes, the TMS320DM8167SCYG is pin-compatible with TMS320DM8168CYG and TMS320DM8165CYG, all using the identical FCBGA-1031 (25 mm × 25 mm) package. Pin assignments, power domains, and peripheral signal mappings are fully aligned across the family, enabling hardware reuse and migration paths-though functionality like SGX530 (DM8168) or HDVICP2 count (DM8165 = 2) differs per variant.
