Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM1808BZKD4 | 456-MHz ARM926EJ-S, 128KB SRAM, identical ZKB package but rated for extended temperature range (–40°C to 105°C) | Preferred for automotive or outdoor industrial deployments requiring higher thermal margin | Select when operating ambient exceeds 85°C or long-term reliability at elevated junction temperatures is required |
| AM3352BZCZD60 | ARM Cortex-A8 core at 600 MHz, 128KB L2 cache, PRU-ICSS instead of PRUSS, different pinout and memory map | Targets higher-performance Linux applications with richer graphics and multimedia support | Choose only if migrating to Cortex-A architecture and redesigning PCB/layout; not pin-compatible with AM1707DZKBD4 |
Compared with AM1808BZKD4, AM1707DZKBD4 offers lower power consumption at 375 MHz and commercial/industrial thermal grade; compared with AM3352BZCZD60, it provides proven ARM9 deterministic latency and simpler migration path from legacy ARM9 designs - but lacks Cortex-A8 performance and modern peripheral sets.

FAQ
What is the maximum guaranteed operating frequency of the AM1707DZKBD4?
The AM1707DZKBD4 is specified for 375 MHz operation at 1.2 V core voltage across commercial and industrial temperature ranges. This frequency is production-validated per TI's SPRS637E datasheet and supported by the on-chip PLL and power management subsystem. Higher frequencies (e.g., 456 MHz) require 1.3 V and apply only to other variants like AM1707DZKBD5, not the DZKBD4 suffix.
Does the AM1707DZKBD4 include an integrated Ethernet PHY?
No, the AM1707DZKBD4 integrates only the Ethernet MAC (EMAC) with RMII interface and MDIO management port. An external PHY chip (e.g., DP83848) must be used for physical layer signaling. The device does not contain an embedded analog PHY - unlike its USB controllers, which integrate full PHY functionality for both USB0 and USB1.
Can the AM1707DZKBD4 run Linux operating systems?
Yes, the AM1707DZKBD4 supports Linux distributions including TI's Processor SDK Linux and community-supported Ångström. Its ARM926EJ-S core with MMU, 128KB SRAM, and 16KB caches meets minimum requirements for lightweight Linux kernels and user-space applications targeting industrial HMI and gateway use cases.
What is the function of the PRUSS in the AM1707DZKBD4?
The Programmable Real-Time Unit Subsystem (PRUSS) in the AM1707DZKBD4 consists of two independent 32-bit PRU cores, each with 4KB instruction RAM and 512 bytes data RAM. It handles time-critical I/O tasks - such as bit-banged protocols, encoder counting, or PWM waveform generation - freeing the ARM9 core for higher-level application logic and OS services.
Is the AM1707DZKBD4 pin-compatible with other AM17xx variants?
Yes, all AM17xx devices in the ZKB package (including AM1705, AM1707, and AM1708) share identical 256-ball BGA pinouts and mechanical footprint. However, peripheral enablement and signal multiplexing differ per variant - for example, AM1707DZKBD4 enables all three McASP ports and dual USB, while AM1705 may disable certain modules. Always verify signal mapping in the specific device's datasheet.
