AM1707CZKB4

The AM1707CZKB4 is a Sitara™ ARM-based microprocessor from Texas Instruments featuring a single ARM926EJ-S core running at 456 MHz. Designed for embedded applications, it delivers a balanced combination of CPU performance and an integrated peripheral set for connectivity, memory interfacing, and real-time control.

Its architecture and peripheral integration make it suitable for embedded systems that require Ethernet, USB, multimedia I/O and flexible external memory options, all in a compact 256-ball BGA package for surface-mount assembly.

Key Features

• Core and Performance  ARM926EJ-S 32-bit core running at 456 MHz with support for 32-bit and 16-bit (Thumb®) instructions and ARM Jazelle® technology.
• On-chip Memory and Caches  Includes 16 KB instruction cache, 16 KB data cache, 128 KB of on-chip RAM, 64 KB ROM and 8 KB of RAM for the vector table.
• Programmable Real-Time Subsystem (PRUSS)  Dedicated PRU subsystem with two PRU cores providing 4 KB instruction RAM per core and 512 bytes of data RAM per core for deterministic I/O and offloading real-time tasks.
• High-performance DMA  Enhanced DMA controller (EDMA3) with up to 32 independent DMA channels and multiple transfer controllers for low-latency data movement.
• Memory Interfaces  Two external memory interfaces (EMIFA and EMIFB) supporting NOR, NAND and 16-bit SDRAM configurations and a 16-bit SDRAM interface with up to a 256-MB address space.
• USB and Storage  USB 2.0 OTG port with integrated PHY and USB 1.1 OHCI host with integrated PHY; MMC/SD and SDIO host interfaces for removable storage.
• Networking and Connectivity  10/100 Mbps Ethernet MAC (EMAC) with RMII interface and MDIO for PHY management; I2C, SPI, three UARTs and multiple serial ports for peripheral connectivity.
• Audio and Display  Three multichannel audio serial ports (McASPs) with TDM/I2S support and an integrated LCD controller for display subsystems.
• Timers and PWM  Multiple general-purpose timers, watchdog timer, enhanced PWM modules and capture modules for control and timing functions.
• Debug and Power Features  Embedded ICE-RT for real-time debug and clock-gating features for power management.
• Package and Environmental  256-ball BGA (17 × 17 mm) surface-mount package; commercial-grade device with an operating temperature range of 0 °C to 90 °C and RoHS compliant.

Typical Applications

• Industrial Control  Real-time I/O, deterministic control and peripheral integration using PRUSS and EDMA for motor control, PLCs and factory automation subsystems.
• Embedded Networking Devices  Integrated 10/100 Ethernet and USB 2.0 OTG makes the device suitable for networked embedded gateways, controllers and field devices.
• Human-Machine Interfaces (HMI)  LCD controller and peripheral interfaces provide a platform for displays and user interfaces in appliances and instrumentation.
• Audio and Multimedia Interfaces  Multichannel audio serial ports and SD/MMC support enable designs for audio input/output and local storage in consumer and industrial products.

Unique Advantages

• Highly integrated peripheral set: Combines USB 2.0 OTG, USB 1.1 host, Ethernet MAC, MMC/SD, LCD controller and multiple serial interfaces to reduce external components and BOM complexity.
• Real-time I/O offload with PRUSS: Two PRU cores with dedicated instruction and data RAM allow deterministic processing and offloading of timing-critical tasks from the main CPU.
• Robust DMA and memory handling: EDMA3 with 32 channels and flexible EMIF support enables high-throughput transfers between peripherals and external memory.
• Compact surface-mount package: 256-ball BGA (17×17 mm) provides high pin density for complex systems while supporting standard surface-mount assembly processes.
• Commercial-grade and RoHS compliant: Rated for 0 °C to 90 °C operation and RoHS compliance for regulatory and manufacturing consistency.
