RF transceiver boosts in-building performance
Available now from ZMD is the company's second-generation ZMD44102 RF transceiver integrated circuit and starter kits.
The ZMD21013 suits consumer, medical and industrial products requiring multiple sensors.
Sample devices benefiting from the MUSic family include wearable monitors for assessing blood pressure, glucose, heart rate levels; consumer devices using altimeters, barometers and navigation functions; and industrial instruments like scales and flow and pressure monitors.
Other suitable applications include products where highest precision and lowest power consumption are essential qualities.
The ZMD21013 incorporates a sophisticated analogue front-end, including a programmable gain amplifier, a 16bit Delta-Sigma-ADC and a power-saving analogue sampling architecture.
With its high level of integration and smart power architecture, the ZMD21013 can dramatically reduce the average overall bill of materials and power consumption of an entire sensor-based system.
The result is an average power consumption of 25 to 30uW during normal operations and less than 1uW in idle mode.
Beyond the common signal measurement mode, the ZMD21013 supports an additional temperature measurement mode and an auto-zero mode, which allows monitoring of long-term stability drifts and offsets for compensation and correction purposes.
The ZMD21013 application-specific standard product (ASSP) contains an on-chip clock generator and a 16x8bit EEPROM to store nonvolatile configuration data, calibration coefficients and an optional user-programmable identification.
An SPI-compatible serial interface connects the ZMD21013 to the customer's specific external microcontroller or digital signal processor.
The ZMD21013 can be ordered for consumer temperature ranges from 0 to +70C as well as for industrial temperature ranges from -25 to +85C.
The ZMD21013 will be available as engineering samples in the first quarter of this year and will be available in quantities in the second quarter.
The devices are available in TSSOP20 (4.4 x 4.6mm) packages.
