The TMS570xxxx6 microcontroller has two different supply levels required. These are nominally 3.3V and 1.5V.
- 3.3V supplies:
- Min required = 3.0V, Max allowed = 3.6V
- VCCIO: Supply for the I/Os
- VCCP: Supply for the flash pump
- VCCAD: Supply for the on-chip Analog-to-Digital Converter (ADC)
- ADREFHI: High reference voltage for the ADC
- 1.5V supply:
- Min required = 1.35V, Max allowed = 1.65V
- VCC: Supply for the microcontroller core logic and RAM blocks
The external supply regulators must also monitor these supplies and assert power-on reset to the micro whenever any of the supply goes out of regulation.
The full electrical requirements for these supplies are specified in the TMS570LS datasheet at TMS570LS20216/20206/10216/10206/10116/10106 16/32-Bit RISC Flash Microcontroller page 64.
