AM1707BZKBD4

The AM1707BZKBD4 is a Sitara™ ARM926EJ-S microprocessor IC delivering a single 32-bit core at 456 MHz in a 256-ball BGA (17×17) package. Designed for embedded and industrial applications, it combines a high-performance ARM926EJ-S core with integrated peripherals and memory interfaces to support networked, real-time and HMI-centric designs.

With industrial-grade temperature range and a broad set of I/O including Ethernet, USB, LCD controller and SDRAM interfaces, the AM1707BZKBD4 targets embedded systems that require integration, deterministic I/O and robust connectivity.

Key Features

• Core — ARM926EJ-S single 32-bit core running at 456 MHz, supporting 32-bit and 16-bit (Thumb®) instruction sets and ARM Jazelle technology.
• Memory and Cache — 16 KB instruction cache and 16 KB data cache, with on-chip memory components including 8 KB vector table RAM and 64 KB of ROM; external SDRAM controller support is provided.
• External Memory Interfaces — Two external memory interfaces (EMIFA and EMIFB) supporting NOR/NAND and 16-bit or 32-bit SDRAM configurations with defined address spaces.
• Connectivity — Integrated 10/100 Mbps Ethernet MAC (EMAC) with RMII and MDIO management; MMC/SD and SDIO support for removable storage and host-port interface (HPI) with muxed 16-bit address/data bus.
• USB Subsystem — USB 2.0 OTG port with integrated PHY and USB 1.1 OHCI host with integrated PHY, supporting host and device roles and multiple endpoint types.
• Multimedia and Display — LCD controller for direct display interfacing and multimedia card (MMC)/Secure Digital (SD) support.
• Real-Time and Deterministic I/O — Programmable Real-Time Unit Subsystem (PRUSS) with two independent PRU cores, each with dedicated instruction and data RAM, for offloading real-time tasks.
• Peripherals and Timing — Multiple serial interfaces including I2C, three 16550-type UARTs, two SPI ports, three McASP audio serial ports, enhanced PWMs, eCAP modules, and timers including a 64-bit general-purpose timer and watchdog timer.
• DMA and System Control — Enhanced DMA controller (EDMA3) with multiple channels and system control coprocessors (CP15) to manage transfers and system-level functionality.
• Package and Environmental — 256-ball BGA (17×17) surface-mount package; industrial operating temperature range of –40°C to 90°C; RoHS compliant.

Typical Applications

• Industrial Control and Automation — Deterministic PRU cores, PWM and timer subsystems plus industrial temperature rating make it suitable for motor control, motion controllers and factory automation I/O.
• Networked Embedded Devices — Integrated 10/100 Ethernet MAC and USB OTG/host support enable gateway, router and connected sensor-node designs.
• Human-Machine Interfaces (HMI) — LCD controller and multimedia interfaces support display-driven user interfaces and control panels.
• Storage and Data Logging — MMC/SD and SDIO support together with HPI provide options for removable or high-bandwidth storage in embedded recorders and loggers.

Unique Advantages

• Highly Integrated Peripheral Set: On-chip Ethernet, USB (OTG and host), LCD controller, McASP audio ports and multiple serial interfaces reduce external components and PCB complexity.
• Deterministic Real-Time Offload: PRUSS with dedicated instruction and data RAM enables predictable, low-latency handling of time-critical tasks outside the main CPU.
• Flexible Memory Support: Dual external memory interfaces and SDRAM controller options accommodate various external memory configurations and performance needs.
• Industrial-Grade Reliability: –40°C to 90°C operating range and surface-mount 256-BGA package suited for extended-temperature embedded deployments.
• Rich DMA and System Control: Enhanced DMA (EDMA3) and system control coprocessors streamline high-throughput data movement and efficient system management.
• Power Management Capabilities: Standard power-management mechanisms and software-controllable PRUSS enable power-optimized operation where applicable.
