Texas Instruments OMAP5910GGZG2

Overview

OMAP5910GGZG2 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 192 KB on-chip SRAM, SDRAM interface support, and integrated LCD controller for STN/TFT panels. It targets handheld multimedia terminals requiring real-time signal processing and application-level control.

For engineers reviewing the OMAP5910GGZG2 datasheet, OMAP5910GGZG2 pinout, OMAP5910GGZG2 application, or OMAP5910GGZG2 equivalent, key selection considerations include dual-core interprocessor communication via mailbox registers and shared memory, 16-bit SDRAM interface timing compliance, USB host/function peripheral integration, and McBSP-based audio codec interfacing capability.

Technical Context

The OMAP5910GGZG2 implements tightly coupled MPU and DSP subsystems sharing peripherals including USB, McBSP, I²C, and LCD controller. The MPU runs ARM925T with MMU support, while the DSP executes C55x instructions optimized for low-power audio/video algorithms.

System clocking uses dual oscillators: a 32-kHz crystal for RTC and a 12/13-MHz base oscillator feeding PLLs to generate core clocks. Power management supports multiple sleep modes with configurable wake-up sources including STAT_VAL/WKUP and real-time clock alarms.

FAQ

What is the maximum supported SDRAM capacity for OMAP5910GGZG2?

The OMAP5910GGZG2 supports up to 128 MB of external SDRAM via its 16-bit EMIFF interface. This limit arises from the 27-bit address bus width (A0–A26) and standard SDRAM addressing conventions. Designers must configure EMIFF timing parameters per Section 5.8.2 of SPRS197D to ensure reliable operation at target clock rates.

Does OMAP5910GGZG2 support USB device mode with standard HID class drivers?

Yes, OMAP5910GGZG2 supports USB 1.1 function (device) mode and can implement HID class functionality using its integrated USB peripheral. However, full HID descriptor handling and enumeration require firmware-level driver development - the hardware provides the PHY and endpoint control logic but no built-in class stack.

How does the OMAP5910GGZG2 handle interprocessor interrupts between ARM925T and C55x cores?

The OMAP5910GGZG2 uses dedicated mailbox registers and level-sensitive interrupt lines mapped to both MPU and DSP interrupt controllers. Writing to a mailbox register asserts an interrupt on the target core; the interrupt vector and handler must be configured separately in each core's firmware per Sections 3.12.1 and 3.17 of SPRS197D.

Can OMAP5910GGZG2 drive a 480×640 TFT LCD panel directly?

Yes, OMAP5910GGZG2's integrated LCD controller supports 480×640 resolution in TFT mode using programmable timing registers (e.g., LCD_TIMING1/2). However, pixel clock generation depends on PLL configuration - designers must verify that the selected base oscillator (12/13 MHz) and PLL settings yield a stable pixel clock within panel specifications per Section 5.12.

What are the power supply requirements for OMAP5910GGZG2 core and I/O rails?

OMAP5910GGZG2 requires separate 1.6–1.8 V for CVDD (core) and 3.0–3.6 V for DVDD (I/O), with strict sequencing: CVDD must ramp before DVDD and remain active during DVDD transitions. Section 3.14.1 of SPRS197D specifies decoupling capacitor values (e.g., 10 µF bulk + 0.1 µF ceramic per power ball) and noise isolation techniques for stable operation.
