- DMA controller: Reduces CPU load by handling data transfers, improving system efficiency.
- Low 1.8V operation: Enables battery-powered designs with reduced power consumption.
- 128KB flash / 32KB RAM: Sufficient memory for protocol stacks and data buffering.
- Comprehensive protection features: Brown-out detect, POR, and WDT ensure robust operation in harsh environments.
Industrial Ethernet Gateways
The ARM7 core at 55MHz, combined with DMA, handles TCP/IP protocol stacks efficiently. The 128KB flash stores firmware and web pages.
Medical Monitoring Devices
Low 1.8V operation reduces power consumption for portable devices. The 32KB RAM buffers sensor data, while the WDT ensures continuous operation.
Building Automation Controllers
With 100 I/O pins in a TFBGA package, it interfaces with multiple sensors and actuators. The brown-out detector prevents erratic behavior during power dips.
Point-of-Sale Terminals
The DMA accelerates data transfer between UART and memory, improving transaction speed. The POR ensures reliable boot-up.
Robotics Control Boards
PWM outputs control servo motors, while the ARM7 core executes complex motion algorithms. The 1.65V minimum voltage allows operation from a single Li-ion cell.
Smart Grid Meters
The 128KB flash stores calibration and tariff data. The brown-out reset protects against power line transients, and the -40°C to 85°C range suits outdoor installations.
