supported by an ARM Cortex M0+ controller and accelerators for sample-rate conversion, matrix processing, data compaction, and power management circuitry (PMIC). The PMIC operates from a battery source (2.9- 4.5V) and generates the required voltages for the readout IC. It supports dynamic voltage scaling optimised for, but not limited to, low power and high performance applications , www.imec.b e
