80 MHz Cortex-M3 with 384 KB flash
The LM3S2U93-IBZ80-A1T: The core supply operates from 1.235 V to 1.365 V, a narrow window that demands a regulated rail — not a direct battery.
Industrial temperature and package constraints
The 108-LFBGA (body 10x10 mm, ball pitch 0.80 mm typical for this package class) demands multilayer PCB routing; a two-layer board cannot fan out all 108 balls without blind vias. On-chip peripherals include a 16-channel 10-bit ADC, DMA controller, PWM, watchdog timer, and a brown-out detect/POR circuit that monitors the 1.235 V–1.365 V core rail.
Obsolete — sourcing through surplus channels
Texas Instruments has marked the LM3S2U93-IBZ80-A1T as obsolete. No official successor order code is recorded in the lifecycle documentation.
