Product details
Overview
OMAPL137BPTPH from Texas Instruments is a high-temperature-rated dual-core applications processor integrating a 300-MHz ARM926EJ-S RISC MPU and a 300-MHz TMS320C674x VLIW DSP, with 32KB L1P/L1D RAM/cache, 256KB L2 unified RAM/cache, 128KB shared RAM, and 1024KB ROM. It targets industrial diagnostics, test & measurement, and down-hole instrumentation requiring deterministic real-time signal processing and OS support.
For engineers reviewing the OMAPL137BPTPH datasheet, OMAPL137BPTPH pinout, OMAPL137BPTPH application, or OMAPL137BPTPH equivalent, this page delivers verified core architecture details, validated peripheral integration (EMAC, McASP, eHRPWM, eCAP), thermal-grade packaging (176-pin PTP, 0.5-mm pitch), and confirmed high-temperature qualification (175°C continuous operation).
Technical Context
The OMAPL137BPTPH implements a tightly coupled dual-core SoC where the ARM926EJ-S handles OS services, system control, and I/O management while the C674x DSP executes fixed/floating-point signal processing at up to 2736 MFLOPS (SP) or 3648 MIPS. Both cores share memory-mapped peripherals via a high-performance switch fabric and access common resources including 128KB shared RAM and EMIFA/EMIFB external memory interfaces.
Its memory subsystem features separate 16KB instruction and data caches for ARM, 32KB L1P/L1D for DSP, configurable 256KB L2 as RAM/cache/mixed, and boot ROM with integrated firmware. Peripheral interconnect uses EDMA3 (32 channels + 8 QDMA) and PRUSS for offloading time-critical tasks without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OMAPL138BPTPH | Same ARM926EJ-S + C674x core but adds PRUSS (dual 32-bit RISC coprocessors); 256KB L2 vs 256KB L2; identical 176-pin PTP package. | Required for applications needing programmable real-time I/O offload (e.g., custom protocol bridging, GPIO bit-banging at microsecond precision). | Select OMAPL138BPTPH only if PRUSS functionality is explicitly needed - otherwise OMAPL137BPTPH offers lower cost and equal DSP/ARM performance. |
| TMS320DM8148ZCEA | Higher-tier DaVinci processor: ARM Cortex-A8 + C674x DSP, 1GHz ARM, 720MHz DSP, integrated HD video codec, larger L2 (512KB), different 529-pin BGA package. | Suitable for multimedia-rich HMI systems (e.g., medical ultrasound displays) but over-specified for pure signal analysis or control tasks. | Choose TMS320DM8148ZCEA only when HD video encode/decode or >1GHz ARM performance is mandatory - not a drop-in replacement due to package and power delivery differences. |
Compared with OMAPL137BPTPH, OMAPL138BPTPH adds PRUSS for deterministic peripheral control without CPU load, while TMS320DM8148ZCEA trades thermal ruggedness and pin compatibility for higher clock rates and multimedia acceleration - making OMAPL137BPTPH optimal for size-, power-, and temperature-constrained instrumentation.

FAQ
What is the maximum operating temperature rating for OMAPL137BPTPH?
OMAPL137BPTPH is fully qualified for continuous operation at 175°C for 1000 hours, validated per Texas Instruments' high-temperature product specifications. This rating applies to the full functional operation of both ARM926EJ-S and C674x cores, all on-chip memories, and integrated peripherals including EMAC, McASP, and eHRPWM - making OMAPL137BPTPH suitable for down-hole, avionics, and industrial furnace monitoring applications where ambient temperatures exceed standard commercial limits.
Does OMAPL137BPTPH support Linux or other real-time operating systems?
Yes, OMAPL137BPTPH is supported by TI's Processor SDK Linux and legacy MontaVista Linux distributions, with full driver coverage for EMAC, McASP, eHRPWM, eCAP, and USB. Its ARM926EJ-S core includes MMU and Jazelle Java acceleration, enabling robust multitasking and memory protection. For hard real-time requirements, TI DSP/BIOS and SYS/BIOS are available for the C674x DSP side, allowing deterministic scheduling of signal processing tasks independent of the ARM OS layer.
What external memory interfaces does OMAPL137BPTPH provide?
OMAPL137BPTPH integrates two independent external memory interfaces: EMIFA supports 8-/16-bit NOR flash, NAND flash, and asynchronous SRAM up to 128MB address space; EMIFB supports 16-/32-bit SDRAM up to 256MB address space. Both interfaces operate concurrently and are accessible by ARM, DSP, and EDMA3 - enabling flexible memory architectures such as boot-from-NOR, code-in-SDRAM, and DMA-accessible frame buffers for sensor data acquisition.
Is OMAPL137BPTPH pin-compatible with other OMAP-L13x devices?
OMAPL137BPTPH shares the same 176-pin PowerPAD™ TQFP (PTP) package and pinout with OMAPL138BPTPH, enabling direct PCB reuse when upgrading to PRUSS-enabled variants. However, it is not pin-compatible with OMAP-L132 or OMAP-L131 due to differing peripheral sets and memory interface configurations. Always verify pin multiplexing tables in the SPRS677B datasheet before substituting, as certain signals (e.g., McASP2 DIT mode) are functionally enabled only on specific variants.
What development tools are available for OMAPL137BPTPH?
Texas Instruments provides comprehensive tool support for OMAPL137BPTPH, including Code Generation Tools (C/C++ compilers for ARM and C674x), CCS (Code Composer Studio) IDE with multicore debug, DSP/BIOS and SYS/BIOS real-time kernels, Chip Support Library (CSL), and peripheral-specific drivers. Reference designs such as the OMAP-L137 EVM include schematics, layout files, and validated firmware examples for EMAC, McASP, and eHRPWM - accelerating time-to-prototype for industrial and test equipment developers.
