Texas Instruments OMAP5910GGZG1

Overview

OMAP5910GGZG1 from Texas Instruments is a dual-core system-on-chip integrating a 16-bit TMS320C55x DSP core and a TI-enhanced ARM925T RISC processor, operating at up to 200 MHz (MPU) and 100 MHz (DSP), with integrated SDRAM controller, LCD controller, USB host/function, and McBSP peripherals. It targets handheld multimedia terminals requiring real-time video decode, voice processing, and display control.

For engineers reviewing the OMAP5910GGZG1 datasheet, OMAP5910GGZG1 pinout, OMAP5910GGZG1 application, or OMAP5910GGZG1 equivalent, key selection considerations include dual-core interprocessor communication via mailbox registers and shared memory, 16-bit SDRAM interface timing compliance, LCD panel timing support for STN/TFT, and USB 1.1 transceiver integration with dedicated DP/DM pins.

Technical Context

The OMAP5910GGZG1 implements tightly coupled MPU and DSP subsystems sharing memory interfaces and peripherals via MPUI and Traffic Controller. Its clock architecture includes independent PLLs for MPU (up to 200 MHz) and DSP (up to 100 MHz), with base oscillator options of 12 MHz or 13 MHz and a separate 32-kHz RTC crystal input.

System-level features include hardware accelerators for DCT/iDCT, motion estimation, and pixel interpolation-dedicated to JPEG/MPEG-4 video processing-and a configurable 16-bit external memory interface supporting SDRAM, Flash, and SRAM with programmable wait states and burst modes.

FAQ

What is the maximum supported SDRAM density for OMAP5910GGZG1?

The OMAP5910GGZG1 EMIFF interface supports up to 128 MB of 16-bit SDRAM, configured via programmable row/column address bits and bank selection. This limit arises from the 25-bit address bus width and internal memory controller architecture documented in Section 3.11 of SPRS197D. The OMAP5910GGZG1 does not support DDR or LPDDR memory types.

Does OMAP5910GGZG1 support USB device mode with host negotiation (OTG)?

No, the OMAP5910GGZG1 implements separate USB host controller and USB function peripheral blocks but lacks USB On-The-Go (OTG) support. It cannot dynamically switch roles or manage ID pin detection. The USB.DP and USB.DM pins are fixed for either host or function operation based on software configuration, as specified in Section 3.6.2 and 3.6.3 of SPRS197D.

Can the OMAP5910GGZG1's DSP core execute code from external SDRAM?

Yes, the OMAP5910GGZG1 DSP core can execute code from external SDRAM when the MMU is enabled and appropriate memory mapping is configured via the DSP MMU registers. Section 3.4 of SPRS197D confirms managed external memory access, though performance-critical code is typically loaded into on-chip DARAM or SARAM for deterministic timing.

What is the purpose of the FUNC_MUX_CTRL_B register in OMAP5910GGZG1?

FUNC_MUX_CTRL_B register (address FFFE:C008) configures multiplexed pin functions for peripherals including the internal oscillator control. As revised in SPRS197D page 126, it determines whether OSC1_OUT is enabled or left unconnected when the internal oscillator is disabled - a critical setting for external clock source integration.

How does the OMAP5910GGZG1 handle power sequencing between CVDD and VDD_IO rails?

The OMAP5910GGZG1 requires CVDD (core) to be ramped before VDD_IO (I/O) during power-up, and CVDD must remain active until VDD_IO is fully discharged during power-down. This sequencing is enforced by internal power-on-reset circuitry and documented in Section 5.14 of SPRS197D to prevent latch-up or undefined I/O states.
