The LM3S6110-IBZ25-A2: At 25 MHz, this is not a high-throughput DSP or graphics controller; it is a control-oriented MCU for moderate-speed data acquisition, protocol parsing, and real-time I/O management.
The 108-BGA package measures 10x10 mm.
The LM3S6110-IBZ25-A2 is officially marked obsolete. No last-time-buy window or successor part number is recorded in the lifecycle data.
There is no direct pin-compatible or drop-in replacement recorded for the LM3S6110-IBZ25-A2. A redesign would typically move to a current TI Cortex-M3 or Cortex-M4 family with Ethernet, such as the TM4C129x or MSP432E series, but this involves a new PCB layout and firmware migration. For legacy repairs, the only option is to source the exact obsolete part through independent distribution.
