What are the key features of LM3S1608-IBZ50-A2T?

  • 32-bit ARM Cortex-M3 core at up to 8.192 MHz
  • 128 KB on-chip flash program memory
  • 52 general-purpose I/O lines
  • On-chip ADC for analog signal acquisition
  • Boundary scan (JTAG) for automated board test
  • 108-ball PBGA package (S-PBGA-B108)
  • Industrial temperature range operation

What is LM3S1608-IBZ50-A2T used for?

The LM3S1608-IBZ50-A2T serves industrial control panels, remote terminal units, and sensor-gateway designs where a compact 32-bit ARM Cortex-M3 MCU with 52 I/O lines and an integrated ADC reduces external analog front-end component count. Its industrial temperature rating ensures reliable operation in factory automation and building management systems exposed to wide thermal variations. The BGA form factor makes it suitable for high-density embedded boards where through-hole or LQFP placement is impractical.

Frequently Asked Questions

How much flash memory and how many I/O lines does the LM3S1608-IBZ50-A2T offer?

The LM3S1608-IBZ50-A2T provides 128 KB of on-chip flash program memory and 52 general-purpose I/O lines, giving embedded designers ample program storage and peripheral connectivity for sensor-interface and control applications in a compact 108-ball BGA package.

Does the LM3S1608-IBZ50-A2T include boundary scan, and how does that benefit board-level testing?

Yes, the device supports JTAG boundary scan, enabling automated interconnect testing on assembled PCBs to quickly identify open or shorted nets without physical probe access, which is particularly valuable for densely routed 108-ball BGA boards in industrial production environments.

For which industrial sensor or control applications is the LM3S1608-IBZ50-A2T a strong match?

This MCU suits remote terminal units, building automation controllers, and industrial sensor gateways requiring a 32-bit ARM Cortex-M3 processor at 8.192 MHz with an on-chip ADC for direct analog sensor acquisition across 52 I/O channels under industrial temperature conditions.

What package does the LM3S1608-IBZ50-A2T use, and what assembly consideration should designers be aware of?

The device uses a 108-ball plastic BGA package (JESD-30 code S-PBGA-B108), which demands reflow soldering with controlled paste volume and X-ray or AOI inspection after assembly, unlike leaded packages; however, it delivers a significantly smaller PCB footprint than equivalent LQFP or DIP options for the same pin count.
