Product Comparison

The Texas Instruments LM3S818-IQN50-C2 is a robust ARM Cortex-M3-based microcontroller designed for precision industrial and embedded applications. As part of TI's legacy Stellaris LM3S800 series, this MCU combines performance, reliability, and versatile connectivity in a compact 50-pin QFN package.

Key Features

High-Efficiency Core: Built around a 50 MHz ARM Cortex-M3 processor, the LM3S818 delivers rapid execution for real-time control tasks.
Memory Configuration:
- 64 KB Flash for firmware storage.
- 16 KB SRAM for dynamic data handling.
Industrial-Grade Peripherals:
- Analog Integration: 6-channel, 10-bit ADC for sensor interfacing.
- Communication Interfaces: Dual UART, SPI, and I²C modules for seamless device networking.
- PWM & Timers: 4x 32-bit timers and PWM outputs for motor control and signal generation.
Robust Design: Operates across -40°C to +85°C, ideal for harsh environments.

Target Applications

The LM3S818-IQN50-C2 excels in systems requiring precise timing and connectivity:

Industrial Automation: PLCs, motor controllers, and sensor hubs.
Consumer Electronics: Smart appliances and IoT edge devices.
Legacy Upgrades: Cost-effective refresh for older Stellaris-based designs.

Development Ecosystem

TI supports the LM3S818 with:

Software Tools: Code Composer Studio (CCS), Keil, and IAR for code development.
Libraries: StellarisWare® drivers for rapid peripheral configuration.
Debugging: JTAG/SWD interfaces for real-time troubleshooting.

Migration Considerations

While TI now prioritizes the Tiva TM4C series (e.g., TM4C123GH6PM) for newer projects, the LM3S818 remains viable for maintenance or budget-focused designs. Engineers transitioning to modern platforms can leverage TivaWare™ libraries for code compatibility.

Why Choose the LM3S818-IQN50-C2?
With its balanced mix of processing power, memory, and industrial durability, the LM3S818-IQN50-C2 is a proven solution for embedded developers prioritizing reliability and cost efficiency. For datasheets and design resources, visit TI's official product page.
