Product details
Overview
AM1707DZKB3 from Texas Instruments is a 375-MHz ARM926EJ-S™ microprocessor in a 256-ball PBGA (ZKB) package, featuring 128KB on-chip RAM, dual USB ports (USB 2.0 OTG + USB 1.1 OHCI), 10/100 Mbps Ethernet MAC with RMII, and three McASP audio interfaces. It targets industrial automation and portable data terminals requiring real-time OS support and mixed-signal peripheral integration.
For engineers reviewing the AM1707DZKB3 datasheet, AM1707DZKB3 pinout, AM1707DZKB3 application, or AM1707DZKB3 equivalent, this page delivers verified core frequency, memory subsystem layout, peripheral register mapping, thermal specifications for ZKB packaging, and validated alternative microprocessors for ARM9-based embedded control designs.
Technical Context
The AM1707DZKB3 implements an ARMv5TEJ-compliant 32-bit RISC core with separate 16KB instruction and 16KB data caches, MMU support, and Embedded Trace Buffer (ETB). Its clock architecture includes dual PLLs-one for CPU (375 MHz at 1.2 V) and one for peripherals-managed by a Power/Sleep Controller (PSC) with domain-level clock gating.
Peripheral interconnect uses AHB and APB buses with dedicated EDMA3 controller (32 channels + 8 QDMA), enabling zero-copy transfers between McASP FIFOs, EMAC buffers, and external SDRAM via EMIFB (16-/32-bit, 256 MB address space) or NAND/NOR/SDRAM via EMIFA (128 MB).

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM9-based microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM1808BZKN | 456-MHz ARM926EJ-S, same ZKN package but 361-ball BGA; adds SATA controller and security accelerator | Targeted at higher-throughput storage gateways and secure boot applications | Select when >375-MHz performance, SATA, or cryptographic acceleration is required |
| OMAP-L138BZWT | ARM9 + C674x DSP dual-core; 375-MHz ARM + 375-MHz DSP; same 361-ball BGA but different pinout and power sequencing | Optimized for audio analytics, voice recognition, and real-time signal processing | Select when DSP-intensive algorithms (e.g., FFT, filtering) must run alongside ARM applications |
Compared with AM1707DZKB3, AM1808BZKN offers higher CPU frequency and added peripherals in a larger package, while OMAP-L138BZWT trades pure ARM throughput for heterogeneous compute capability-neither is pin-compatible, but both share toolchain and peripheral driver compatibility within TI's ARM9 ecosystem.

FAQ
What is the maximum operating frequency of the AM1707DZKB3 and under what voltage condition?
The AM1707DZKB3 operates at a maximum frequency of 375 MHz when supplied with a 1.2-V core voltage (VDD_CORE). This rating is specified for commercial and industrial temperature ranges and is validated in the SPRS637E datasheet revision. The device also supports lower-frequency operation (e.g., 300 MHz or 266 MHz) at reduced voltage for power-constrained deployments. AM1707DZKB3 does not support the 456-MHz mode, which requires 1.3-V core voltage and is reserved for higher-grade variants like AM1707DZKBA.
Does the AM1707DZKB3 include on-chip memory sufficient to run a lightweight Linux kernel without external SDRAM?
No, the AM1707DZKB3 includes 128KB of on-chip RAM and 64KB of ROM, which is insufficient for loading and executing a standard Linux kernel and root filesystem. External memory is required: EMIFB supports 16-/32-bit SDRAM up to 256 MB, and EMIFA supports NAND/NOR flash for boot code storage. AM1707DZKB3 relies on external SDRAM for runtime execution, with on-chip RAM typically used for boot ROM, cache, or critical real-time buffers.
How many USB interfaces does the AM1707DZKB3 support, and what are their compliance levels?
The AM1707DZKB3 integrates two fully independent USB interfaces: USB0 is a USB 2.0 On-The-Go (OTG) controller compliant with high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) modes, including integrated PHY; USB1 is a USB 1.1 Open Host Controller Interface (OHCI) host controller compliant with full-speed (12 Mbps) only, also with integrated PHY. Both interfaces are electrically isolated and require separate 1.2-V analog supplies (USB0_VDDA12 and USB1_VDDA12). AM1707DZKB3 does not support USB 3.x or SuperSpeed.
Can the AM1707DZKB3 directly interface with an LCD panel, and what display capabilities does it support?
Yes, the AM1707DZKB3 includes a dedicated LCD controller supporting passive and active matrix panels with RGB, YUV, and serial interface outputs. It handles resolutions up to VGA (640×480) with 16- or 24-bit color depth, programmable pixel clocks, and hardware cursor overlay. The controller supports both synchronous and asynchronous modes and integrates DMA for frame buffer transfers. AM1707DZKB3 does not include HDMI or MIPI DSI transmitters; external bridge ICs are required for modern digital displays.
What debugging interfaces are available on the AM1707DZKB3, and are they accessible via standard JTAG?
The AM1707DZKB3 provides IEEE 1149.1 JTAG (TCK/TMS/TDI/TDO/TRST) for boundary-scan and core debug, plus an Embedded Trace Buffer (ETB) with 4KB memory for instruction and data trace capture. Debugging is supported via ARM CoreSight-compliant tools using the JTAG interface; no SWD or cJTAG is implemented. The ETB connects internally to the ARM926EJ-S ETM but lacks a routed trace port-trace data must be read through JTAG. AM1707DZKB3 also supports Embedded ICE-RT for real-time breakpoint and watchpoint control during active execution.
