Patent ID: 8755745

Claim:
A Microsystem comprising a semiconductor base die made of dual-mode functional blocks that can be used either in a Bluetooth Low Energy-compliant or Zigbee/IEEE 802.15.4-compliant mode with: a microcontroller and associated non-transitory RAM memories, a programmable and non-programmable non-transitory program memory-ROM and Flash-like, a power management unit and voltage regulators, a conditioning and acquisition block for the processing and digitization of signals coming from one or several sensors as well as a cognitive and reconfigurable transceiver, wherein the radio receive chain of the cognitive and reconfigurable transceiver is made of several functional blocks whose technical characteristics can be dynamically adjusted by a Radio-Reconfigurator Entity in function of RF propagation and interference level conditions, with: a low noise amplifier/LNA adjustable in terms of gain, linearity and noise figure; a pass-band filter and low-pass filters adjustable in terms of roll-off factor/sharpness and bandwidth; an analog to digital converter/ADC adjustable in terms of resolution and sampling frequency; and further comprising one or more semiconductor dies, integrated vertically and horizontally with the base die, with: a complerrientary semiconductor die implementing the remaining functional blocks for the realization of a complete Zigbee/IEEE 802. 15.4-compliant solution with: a IEEE 802.15.4-compliant hardware accelerator for the processing of time-sensitive data and a programmable and non-programmable non-transitory program memory-ROM and Flash-like-that contains the whole Zigbee/IEEE 802.15.4-compliant software stack, a sensor die implementing a MEMS (Micro-Electro-Mechanical Systems) sensor, and a power die implementing an energy scavenger and energy conditioning/storage, and a passives die implementing RLC components (resistances, inductances capacitors . . . ).
