3 / 223 page  OMAP-L137 www.ti.com SPRS563F – SEPTEMBER 2008 – REVISED FEBRUARY 2013 1.2 Description The OMAP-L137 is a low-power applications processor based on an ARM926EJ-S™ and a C674x DSP core. It consumes significantly lower power than other members of the TMS320C6000™ platform of DSPs. The OMAP-L137 enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and high processing performance life through the maximum flexibility of a fully integrated mixed processor solution. The dual-core architecture of the OMAP-L137 provides benefits of both DSP and Reduced Instruction Set Computer (RISC) technologies, incorporating a high-performance TMS320C674x DSP core and an ARM926EJ-S core. The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously. The ARM core has a coprocessor 15 (CP15), protection module, and Data and program Memory Management Units (MMUs) with table look-aside buffers. It has separate 16K-byte instruction and 16K- byte data caches. Both are four-way associative with virtual index virtual tag (VIVT). The ARM core also has a 8KB RAM (Vector Table) and 64KB ROM. The OMAP-L137 DSP core uses a two-level cache-based architecture. The Level 1 program cache (L1P) is a 32KB direct mapped cache and the Level 1 data cache (L1D) is a 32KB 2-way set-associative cache. The Level 2 program cache (L2P) consists of a 256KB memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two. Although the DSP L2 is accessible by ARM and other hosts in the system, an additional 128KB RAM shared memory is available for use by other hosts without affecting DSP performance. The peripheral set includes: a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output (MDIO) module; two inter-integrated circuit (I2C) bus interfaces; 3 multichannel audio serial ports (McASP) with 16/12/4 serializers and FIFO buffers; 2 64-bit general-purpose timers each configurable (one configurable as watchdog); a configurable 16-bit host port interface (HPI) ; up to 8 banks of 16 pins of general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; 3 UART interfaces (one with RTS and CTS); 3 enhanced high-resolution pulse width modulator (eHRPWM) peripherals; 3 32-bit enhanced capture (eCAP) module peripherals which can be configured as 3 capture inputs or 3 auxiliary pulse width modulator (APWM) outputs; 2 32-bit enhanced quadrature pulse (eQEP) peripherals; and 2 external memory interfaces: an asynchronous and SDRAM external memory interface (EMIFA) for slower memories or peripherals, and a higher speed memory interface (EMIFB) for SDRAM. The Ethernet Media Access Controller (EMAC) provides an efficient interface between the OMAP-L137 and the network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode. Additionally an Management Data Input/Output (MDIO) interface is available for PHY configuration. The HPI, I2C, SPI, USB1.1 and USB2.0 ports allow the OMAP-L137 to easily control peripheral devices and/or communicate with host processors. The rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. For details on each of the peripherals, see the related sections later in this document and the associated peripheral reference guides. The OMAP-L137 has a complete set of development tools for both the ARM and DSP. These include C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into source code execution.
