This macro-cell is an ultra low consumption Power Management Unit (PMU) core designed for LFoundry 0.15µm LF150 CMOS technology STD (Standard) and LP (Low Power) process. The circuit has 2 LDO voltage regulators, internal voltage and current references, built-in power-on-reset and oscillator, and an 8-bit low power and low frequency ADC for general purpose voltage monitoring. Internal blocks are programmable via 3-pin serial digital interface providing high IP flexibility. The core is easily retargeted to any other CMOS technology with R-poly devices.
