EM Microelectronic-Marin

EM Microelectronic has a design center at its headquarters in Marin, in the French speaking part of Switzerland near the city of Neuchâtel. In order to support its activities worldwide, EM has subsidiaries and additional design centers:

• EM Microelectronic - US Inc., located in Colorado Springs, Colorado (USA), is a subsidiary of EM Microelectronic which is aimed at serving North American customers.
• ASICentrum s.r.o.[2] is a design center located in Prague (Czech Republic). It is involved in the design of digital, analog and mixed-signal ICs.

V3021: Ultra Low Power 1-Bit 32 kHz real-time clock

EM Microelectronic specialises in the design and production of ultra low power, low voltage integrated circuits for battery-operated and field-powered applications in consumer, automotive and industrial products.[1] It has in-house semiconductor fabrication facilities and also uses external foundries.[1]

EM Microelectronic's products include RFID circuits, smart cards ICs, ultra-low power microcontrollers, power management, LCD drivers and displays, sensor and opto-electronic ICs, mixed-mode arrays and standard analog ICs. EM manufacture not only standard circuits and ASICs, but also systems and modules for applications such as access control, radio frequency identification, mobile phones, mass-market consumer appliances, alarm and security systems, utility and heating meters, sensor signal processing, controlling, car immobilization, electronic automotive subsystems and many more.

EM Microelectronic design and develop Bluetooth Low Energy products such as the EM9301.[3] EM is an associate member of the Bluetooth SIG and is contributing through several working group to improve global specification and expertise in ultra-low power design for Bluetooth low energy wireless technology.[4] EM Micro has also a proprietary link family of products with 1Mbits, 2Mbit/s and Long range solutions.

The popularity of EM Microelectronic's range of ~125 kHz RFID devices has led to product from other manufacturers being advertised as "EM4100 compatible" although this may simply mean that the active device embedded in the RFID tag/card is an EM Microelectronic product.
