Product details
Overview
AM3703CUSD100 from Texas Instruments is a Sitara™ ARM® Cortex™-A8 microprocessor operating at up to 1 GHz with adaptive core voltage (0.9–1.2 V), integrated 256-KB L2 cache, POWERVR SGX graphics accelerator (AM3715 only - not present in AM3703), and support for SDRAM, NAND/NOR flash, and MMC/SD via GPMC and SDRC controllers. It targets embedded human-machine interface and industrial control applications requiring real-time OS support including Linux and Android.
For engineers reviewing the AM3703CUSD100 datasheet, AM3703CUSD100 pinout, AM3703CUSD100 application, or AM3703CUSD100 equivalent, key selection considerations include its 423-pin s-PBGA (CUS) package, absence of POWERVR SGX (vs. AM3715), 188 GPIOs with multiplexing, SmartReflex™ power management, and compatibility with OMAP™3 architecture for legacy migration paths.
Technical Context
The AM3703 implements an in-order, dual-issue, superscalar ARMv7-A architecture with TrustZone® security extensions, Thumb®-2 instruction set, and NEON™ SIMD coprocessor. It integrates dedicated subsystems including a 32-channel SDMA controller, three high-speed I²C controllers, five McBSP audio interfaces (two with sidetone), and four McSPI ports.
Its memory subsystem includes a 16-/32-bit SDRAM controller (SDRC) supporting up to 1 GB address space, a general-purpose memory controller (GPMC) with eight chip-selects and glueless NAND/NOR/SRAM interfacing, and on-chip 64-KB SRAM plus 32-KB ROM. The device uses 45-nm CMOS process technology and supports dynamic voltage and frequency scaling (DVFS) via SmartReflex™ AVS.

FAQ
What is the maximum operating frequency of the AM3703CUSD100?
The AM3703CUSD100 operates at up to 1 GHz under specified thermal and voltage conditions. Its adaptive core voltage range (0.9 V to 1.2 V) allows dynamic frequency scaling via SmartReflex™ AVS to balance performance and power. This 1-GHz capability is confirmed in the SPRS616F datasheet revision August 2011, Table 6-1, and applies specifically to the AM3703CUSD100 variant in the CUS package.
Does the AM3703CUSD100 include the POWERVR SGX graphics accelerator?
No, the AM3703CUSD100 does not include the POWERVR SGX graphics accelerator. That feature is exclusive to the AM3715 variant. The AM3703CUSD100 shares the same ARM Cortex-A8 core, memory subsystem, and peripheral set but omits the SGX block - reducing die size, power consumption, and cost while maintaining full software compatibility with AM3715 for non-GPU workloads.
Which package type does the AM3703CUSD100 use, and what are its key mechanical features?
The AM3703CUSD100 uses the 423-pin s-PBGA-N423 (CUS) package with 0.65-mm ball pitch. It has no top-side balls, supports Package-on-Package (POP) memory stacking, and is qualified for extended temperature operation (−40°C to +105°C). Mechanical dimensions and solder mask specifications are defined in Section 7 of the SPRS616F datasheet.
How many general-purpose I/O pins does the AM3703CUSD100 provide, and how are they configured?
The AM3703CUSD100 provides up to 188 general-purpose I/O pins, all multiplexed with alternate peripheral functions (e.g., UART, I²C, McBSP, McSPI). Pin configuration is controlled via register-based pad control modules, allowing runtime reassignment. Specific pin assignments for the CUS package are detailed in Tables 2-3 and Figures 2-5/2-14 through 2-17 of the SPRS616F datasheet.
What memory interfaces are supported by the AM3703CUSD100 for boot and runtime operation?
The AM3703CUSD100 supports boot from NAND flash (with on-die ECC), NOR flash, OneNAND, and MMC/SD via its General Purpose Memory Controller (GPMC) and Multimedia Card interface. For runtime memory, it integrates a 32-bit SDRAM controller (SDRC) supporting LPDDR/DDR2 up to 1 GB address space, plus 64-KB on-chip SRAM and 32-KB ROM for initial boot code execution.
