The TMS320F28026DATR: 60MHz C28x core, 32KB Flash, 6K x 16 RAM, 38-TSSOP package, 20 GPIOs, 7-channel 12-bit ADC, PWM, SCI, SPI, I²C.
60MHz clock rate on the C28x core. Internal oscillator trims the BOM.
That means no further factory orders — no last-time-buy window to catch. The 38-TSSOP package and 1.71V–1.995V core supply are specific enough that a drop-in replacement is not trivial; the closest pin-compatible alternative within the same Piccolo family is the TMS320F28027, which bumps Flash to 64KB and adds a few more PWM channels, but the pinout matches the 38-pin TSSOP footprint. If your design already has code space headroom, the F28027 is the migration path.
Temperature grade and supply rail
The core supply is tight: 1.71V to 1.995V. That means a separate 1.8V rail (or a 3.3V-to-1.8V LDO) is required; the I/O bank runs from the same 1.8V supply, so level translation is needed if the peripherals talk to 3.3V logic.
