AM1707CZKB3

The AM1707CZKB3 is a Sitara AM17xx series microprocessor from Texas Instruments featuring a single ARM926EJ‑S 32‑bit core running at 375 MHz in a 256‑ball BGA (17×17) package. It targets embedded applications where integrated connectivity and memory interfaces are required alongside real‑time control capability.

On‑chip peripherals and subsystem integration — including USB 2.0 and 1.1 with PHYs, a 10/100 Mbps Ethernet MAC, LCD controller, SDRAM interfaces and MMC/SD support — deliver a compact solution for embedded designs that need both application processing and system I/O integration.

Key Features

• Core and Performance  Single ARM926EJ‑S 32‑bit RISC core at 375 MHz with support for 32‑bit and 16‑bit (Thumb) instructions, single‑cycle MAC, Jazelle technology and Embedded ICE‑RT for real‑time debug.
• Memory and Cache  On‑chip memory resources include instruction and data caching (16 KB instruction cache, 16 KB data cache per datasheet), 128 KB of RAM and 64 KB of ROM; additional small RAM regions for vector tables and PRU cores are provided in the subsystem.
• External Memory Interfaces  Two external memory interfaces (EMIFA and EMIFB) with support for NOR and NAND flash, plus SDRAM controllers supporting 16‑bit and 32‑bit configurations and multi‑MB address spaces.
• Connectivity  Integrated USB interfaces (one USB 2.0 with PHY and one USB 1.1 with PHY), and a 10/100 Mbps Ethernet MAC with RMII and MDIO management for networked embedded systems.
• Display and Multimedia  Integrated LCD controller and multimedia peripherals including MMC/SD/SDIO support and three multichannel audio serial ports (McASPs) for audio and display applications.
• Real‑Time and DMA Subsystems  Programmable Real‑Time Unit Subsystem (PRUSS) with two PRU cores for offloading low‑latency I/O tasks, and an Enhanced DMA controller (EDMA3) with numerous channels and transfer controllers to move data efficiently.
• Timers, PWM and Capture  Comprehensive timing peripherals including general‑purpose 64‑bit timers, watchdog timer, enhanced PWMs (eHRPWMs) and enhanced capture (eCAP) modules for control and measurement tasks.
• Package, Mounting and Environmental  256‑ball BGA (17×17) surface‑mount package, commercial grade with an operating temperature range of 0 °C to 90 °C and RoHS compliance.
• Standard System Interfaces  Industry interfaces such as I2C, UARTs (three 16550‑type), SPIs and McASPs provide connectivity to sensors, peripherals and host interfaces.

Typical Applications

• Embedded Networking  Networked devices that require 10/100 Mbps Ethernet and on‑board processing for protocol handling and data aggregation.
• Human‑Machine Interfaces  Systems that combine an LCD user interface with USB connectivity and on‑board storage (MMC/SD) for interactive displays and control panels.
• Industrial and Real‑Time Control  Control applications leveraging the PRU subsystem, PWM modules and rich timer set for deterministic I/O and motor or process control tasks.
• Multimedia and Storage‑Enabled Devices  Products that require audio interfaces (McASP), MMC/SD storage, and on‑chip DMA to handle streaming and media transfer efficiently.

Unique Advantages

• Highly integrated peripheral set: USB 2.0/1.1 with PHYs, Ethernet MAC, LCD controller, SD/MMC and multiple serial interfaces reduce external component count and PCB complexity.
• Real‑time offload with PRU subsystem: Two dedicated PRU cores enable low‑latency I/O processing and deterministic control independent of the main ARM core, improving system responsiveness.
• Flexible memory connectivity: Dual external memory interfaces and support for multiple SDRAM widths and flash types let designers choose memory configurations to match capacity and performance needs.
• Robust DMA and data movement: Enhanced DMA controller with many channels and configurable transfer controllers minimizes CPU overhead for high‑bandwidth data paths.
• Complete peripheral set for embedded designs: Timers, PWMs, UARTs, SPIs, I2C and audio ports provide the I/O needed for a wide variety of embedded applications without extensive add‑on circuitry.
• Commercial‑grade, RoHS‑compliant package: 256‑BGA surface‑mount package with 0 °C to 90 °C operating range simplifies integration into mainstream embedded products while meeting environmental directives.
