Overview of OMAP-L138 C6000 DSP+ARM Processor
The datasheet presents details about the OMAP-L138 C6000 DSP+ARM Processor, a highly integrated System on Chip (SoC) designed by Texas Instruments. It combines a Dual-Core structure, with both a 375-and 456-MHz ARM9-based MPU (ARM926EJ-S Core) and a C674x DSP, supporting a mix of 32- and 16-Bit Thumb instructions as well as DSP Instruction Extensions.
Key Features and Performance
The OMAP-L138 includes an ARM926EJ-S Core leveraging Jazelle technology for enhanced Java acceleration and an Embedded ICE-RT for real-time debugging. It boasts a Single-Cycle MAC and ARM Thumb-2 and ARM9 Memory Architecture, along with 16KB Instruction and Data Caches. Significantly, the C674x DSP extends processing capabilities with a VLIW architecture, enabling up to 3648 MIPS and 2746 MFLOPS. It has 256KB of L2 Unified Mapped RAM/Cache and supports IEEE single and double precision floating-point formats.
Memory and Interfaces
For memory interfacing, the OMAP-L138 offers multiple options including 16-Bit DDR2 and mDDR SDRAM with sizable address spaces. Its broad interface support features UART modules with FIFO, oversampling options, an LCD controller, SPIs, MMC/SD interfaces, I2C Bus, HPI and a flexible PRUSS with two Independent PRU cores. The subsystems support a standard power-management mechanism as well.
Connectivity and Multimedia Support
The processor facilitates diverse connectivity options such as USB 1.1 OHCI with integrated PHY, a USB 2.0 OTG port, and also contains hardware for Ethernet, including support for IEEE 802.3 protocols and both MII/RMII interfaces. In addition to these standard communication interfaces, it includes a Video Port Interface, a Universal Parallel Port for high-speed data exchange, and a SATA controller compatible with SATA II speeds.
Audio, Video and Peripheral Support
The device is well-suited for multimedia applications with a Multichannel Audio Serial Port and Multichannel Buffered Serial Ports supporting multiple audio formats. The Video Port Interface provides for both capturing and display capabilities with support for standard definition. An array of peripherals like enhanced High-Resolution PWMs, Capture modules, General-Purpose Timers, and a Real-Time Clock enhance utility in a variety of applications.
Packaging and Power
The OMAP-L138 is offered in two variants of Pb-Free Plastic Ball Grid Array packages, differentiated by ball pitch size. Various temperature ranges are supported to cater to diverse environmental requirements.
