AM1707CZKBA3

The AM1707CZKBA3 is a Sitara AM17xx series microprocessor from Texas Instruments featuring a single ARM926EJ-S 32‑bit core running at 375 MHz. It integrates a broad set of peripherals and memory interfaces for embedded applications, targeted at industrial designs requiring robust temperature range and on‑chip connectivity.

With integrated USB, Ethernet, SD/MMC support, LCD controller and real‑time subsystem capabilities, the AM1707CZKBA3 delivers a compact, highly integrated MPU option in a 256‑ball BGA package for embedded system designers.

Key Features

• Processor Core ARM926EJ‑S single 32‑bit core at 375 MHz providing deterministic RISC processing for control and application tasks.
• Memory Subsystem On‑chip memories include 16 KB instruction cache, 16 KB data cache, 128 KB RAM, 64 KB ROM and 8 KB vector table RAM; supports external SDRAM via EMIFA/EMIFB for expanded address space.
• High‑performance I/O and Interfaces Integrated USB 2.0 OTG with PHY and USB 1.1 OHCI host with PHY, plus 10/100 Mbps Ethernet MAC (RMII) for wired networking.
• Storage and Display Multimedia Card (MMC)/Secure Digital (SD) support and an LCD controller for user‑interface and storage connectivity.
• Real‑Time Subsystem (PRUSS) Programmable Real‑Time Unit Subsystem with two PRU cores for low‑latency, deterministic I/O and offloaded real‑time tasks.
• Peripheral Set Includes multiple UARTs (16550‑type), I2C, SPI, McASP audio serial ports, enhanced PWM, eCAP modules, and enhanced DMA channels for flexible peripheral control.
• Robust Industrial Grade Industrial temperature operation from −40 °C to 105 °C and RoHS compliant, supplied in a 256‑BGA (17×17) surface‑mount package.

Typical Applications

• Industrial Control Deterministic processing and PRU real‑time I/O support precise control, timing and communication tasks in industrial automation systems.
• Human‑Machine Interfaces (HMIs) Integrated LCD controller, USB and SD/MMC support enable compact HMI designs with local storage and peripheral connectivity.
• Embedded Networking 10/100 Mbps Ethernet and USB 2.0 OTG provide connectivity for networked embedded devices and remote management.

Unique Advantages

• Integrated Connectivity: On‑chip USB (1.1 and 2.0) and Ethernet MAC reduce external components and simplify board design.
• Real‑time Offload: PRUSS with two PRU cores enables offloading of timing‑sensitive tasks from the main CPU for lower latency and deterministic behavior.
• Compact, High‑I/O Package: 256‑ball BGA (17×17) package packs extensive I/O and memory interfaces into a small footprint for space‑constrained designs.
• Industrial Reliability: Specified operation from −40 °C to 105 °C supports deployment in demanding industrial environments.
• Rich Peripheral Set: Multiple UARTs, SPI, I2C, McASP, PWM and DMA channels enable diverse sensor, actuator and communication integrations without complex external logic.
