AM1707BZKB4

The AM1707BZKB4 is a Sitara™ ARM microprocessor integrating a single ARM926EJ-S 32‑bit core running at 456 MHz in a 256‑ball BGA (17×17) package. It targets embedded microprocessor applications that require a high level of peripheral integration and multiple external memory interface options.

Designed for embedded and commercial systems, the device combines processing performance with a broad set of on‑chip interfaces – including Ethernet, USB 1.1/2.0 with integrated PHYs, MMC/SD, LCD controller and SDRAM controllers – to simplify system design and accelerate time to market.

Key Features

• Core and Performance  ARM926EJ‑S RISC core at 456 MHz with single‑cycle MAC and support for 32‑bit and 16‑bit (Thumb®) instruction sets.
• Memory Architecture  On‑chip memory and cache features from the AM17xx family include instruction and data caches and on‑chip RAM; external memory supported via SDRAM controllers and two external memory interfaces (EMIFA and EMIFB) for NOR/NAND and SDRAM devices.
• Connectivity and USB  Integrated connectivity includes a 10/100 Mbps Ethernet MAC and both USB 1.1 (OHCI host) and USB 2.0 OTG ports with integrated PHYs for host and client roles.
• Storage and Expansion  Multimedia Card (MMC)/Secure Digital (SD) and SDIO support for removable storage and expansion.
• Display and Audio  On‑chip LCD controller and multiple multichannel audio serial ports (McASPs) for display and audio subsystem integration.
• Real‑Time Subsystem (PRUSS)  Programmable Real‑Time Unit Subsystem with two independent PRU cores and dedicated instruction/data RAM per core for deterministic I/O and offloaded real‑time processing; PRUSS can be disabled via software to save power.
• DMA and Peripherals  Enhanced DMA controller (EDMA3) and multiple serial interfaces including I2C, SPI, UARTs, eHRPWMs, eCAP and general purpose timers to support diverse peripheral control and high‑throughput data movement.
• Package and Environment  256‑BGA (17×17) surface‑mount package with a commercial operating temperature range of 0 °C to 90 °C; RoHS compliant.

Typical Applications

• Industrial Control and Automation  Deterministic I/O via the PRUSS and extensive timer/PWM resources make the device suitable for motion control, real‑time sensor interfacing and factory automation controllers.
• Networking and Gateway Equipment  Integrated 10/100 Mbps Ethernet and USB 2.0 OTG support enable use in routers, gateways and networked peripherals requiring medium‑speed connectivity.
• Multimedia and HMI Terminals  LCD controller combined with McASPs and external SDRAM interfaces supports human‑machine interfaces, control panels and multimedia playback devices.
• Embedded Consumer and Commercial Devices  MMC/SD storage, multiple serial interfaces and comprehensive I/O make the device well suited for set‑top units, smart appliances and general embedded controllers.

Unique Advantages

• Highly integrated connectivity: Ethernet, dual USB PHYs and MMC/SD support reduce external components and simplify board design.
• Real‑time processing offload: PRUSS with dedicated RAM enables deterministic peripheral control without burdening the main ARM core.
• Flexible memory support: External memory interfaces (EMIFA/EMIFB) and SDRAM controllers provide options for scalable system memory and storage.
• Rich peripheral set: Multiple UARTs, SPI, I2C, McASPs, PWM and capture modules support diverse sensor, actuator and user‑interface requirements.
• Commercial temperature and RoHS compliance: Suitable for mainstream embedded deployments with environmental and regulatory considerations addressed.
