Cortex-M3 MCU with 384 KB Flash and 80 MHz core
The 67 GPIOs are brought out to a 108-ball BGA package measuring 10x10 mm.
An internal oscillator is available, though an external crystal can be used for tighter timing.
Texas Instruments has marked this part as obsolete. For existing BOM lines, procurement will need to source from independent distributors or the surplus market. Each unit should be inspected for date-code consistency and marking integrity — the 108-BGA package can be re-marked, so physical verification (X-ray, decap) is advised for high-reliability builds.
