7.3.8 Voltage Reference (VREF)

The voltage reference (VREF) produces a fixed (constant) voltage, providing references to the analog comparators and external circuitry. The TPLD1201-Q1 has a voltage reference macro-cell to provide references to the two analog comparators. This macro-cell can supply a user selection of fixed voltage references, /2, /3 and /4 reference off of the VCC power supply to the device, and externally supplied voltage references from the VREF Analog Input (shared with IO4). The macro-cell also has the option to output a reference voltage on the VREF Analog Output (shared with IO7).

If VCC/2, VCC/3, and VCC/4 are not used at VREF select, they can be disabled to reduce power consumption.

Force bandgap on keeps the bandgap on while the chip is powered.

Output active buffer parameter enables the active output buffer on VREF.
