The official lifecycle stage is listed as current, but the NRND designation is the practical signal: secure last-time-buy quantities or identify a migration path before the LTB window closes.
The ARM Cortex-M3 core runs at 50 MHz. The 32 KB Flash and 8 KB SRAM (8K x 8) are sized for a single firmware image. Two 10-bit ADC channels handle basic analog feedback.
Texas Instruments still lists it as current, but the NRND flag means the end-of-life process has started. Existing production can continue, but new designs should use a replacement.
