Product details
Overview
AM3703CBP from Texas Instruments is a Sitara™ ARM® Cortex™-A8 microprocessor operating up to 1 GHz with adaptive core voltage (0.9–1.2 V), integrated 256KB L2 cache, POWERVR SGX graphics accelerator (AM3715 only - not present in AM3703), and support for SDRAM, NAND/NOR flash, and multimedia interfaces including McBSP, McSPI, USB OTG/Host, and camera ISP. It targets embedded human-machine interface and industrial control applications requiring high-performance Linux or Android execution.
For engineers reviewing the AM3703CBP datasheet, AM3703CBP pinout, AM3703CBP application, or AM3703CBP equivalent, key selection considerations include its 515-pin s-PBGA (CBP) package, absence of POWERVR SGX (vs. AM3715), 45-nm process node, SmartReflex™ AVS power management, and compatibility with OMAP™3 architecture for legacy migration paths.
Technical Context
The AM3703CBP implements an in-order, dual-issue, superscalar ARMv7-A architecture with TrustZone® security extensions, Thumb®-2 instruction set, and NEON™ SIMD coprocessor. Its memory subsystem includes 32KB L1 instruction and data caches (4-way set-associative), 256KB unified L2 cache, 64KB on-chip SRAM, and 32KB ROM.
Peripheral integration centers on a hierarchical L3/L4 interconnect supporting concurrent access to SDRC (SDRAM controller), GPMC (general-purpose memory controller), multiple McBSP audio ports with SIDETONE, HDQ/1-Wire, four UARTs (one with IrDA), three I²C controllers, five McBSPs, four McSPI ports, and dual USB subsystems (OTG + multiport host) with ULPI or serial PHY interface options.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3715CBP | Includes POWERVR SGX graphics accelerator; otherwise identical pinout, package, and peripheral set | Required for OpenGL ES 2.0-accelerated UIs or video composition; unnecessary for headless or basic GUI use cases | Select AM3715CBP only when GPU acceleration is mandatory; AM3703CBP reduces BOM cost where graphics are software-rendered or absent |
| AM3358BZCZ100 | ARM Cortex-A8 at 1 GHz, but single-core only, no NEON, no SGX, smaller 324-pin package, lacks McBSP SIDETONE and dual USB subsystems | Better suited for cost-optimized, lower-I/O industrial gateways; lacks camera ISP and advanced audio features of AM3703 | Choose AM3358BZCZ100 for simpler, lower-power applications where camera/video/audio are not required |
Compared with AM3715CBP, AM3703CBP removes the SGX GPU to reduce cost and power, making it ideal for non-graphic-intensive HMI; versus AM3358BZCZ100, it offers richer multimedia I/O and higher peripheral concurrency at the expense of larger footprint and higher complexity.

FAQ
What distinguishes AM3703CBP from AM3715CBP?
The AM3703CBP omits the POWERVR SGX graphics accelerator present in the AM3715CBP, resulting in lower power consumption, reduced thermal output, and lower unit cost. Both share identical pinout, package (CBP), core architecture (Cortex-A8), memory subsystem, and peripheral set - making AM3703CBP ideal for applications where GPU acceleration is unnecessary, such as headless controllers or software-rendered UIs.
Does AM3703CBP support camera interfaces?
Yes, the AM3703CBP integrates a dedicated Camera Image Signal Processor (ISP) supporting parallel CMOS/CCD sensors with BT.601/BT.656 digital YCbCr 4:2:2 (8-/10-bit) input, hardware resize (1/4× to 4×), and temporal dithering. This enables direct connection to image sensors without external video decoders, reducing system complexity and BOM count.
What power management features does AM3703CBP include?
The AM3703CBP implements SmartReflex™ Adaptive Voltage Scaling (AVS) with dynamic voltage and frequency scaling (DVFS), allowing real-time adjustment of core voltage (0.9–1.2 V) and clock frequency (300–1000 MHz) based on workload and junction temperature. This minimizes active power without compromising deterministic performance in thermally constrained environments.
Is AM3703CBP pin-compatible with OMAP3 processors?
Yes, the AM3703CBP is fully backward compatible with OMAP™3 architecture at the pin, software, and peripheral level. Its documentation explicitly states compatibility with previous Cortex-A8 Sitara and OMAP processors, enabling drop-in replacement in existing designs targeting OMAP3530 or OMAP3630 - provided power delivery and thermal design accommodate the 45-nm process characteristics.
What operating systems are supported on AM3703CBP?
Texas Instruments provides full software support for AM3703CBP with Linux (including mainline kernel patches), Android (Gingerbread through KitKat), and Windows Embedded CE - all available free of charge. TI's Processor SDK includes BSPs, drivers, graphics libraries (OpenGL ES 1.1), and development tools validated specifically for AM3703CBP hardware configurations.
