ST op-amps

Mon, 28 Nov 2011 14:51:06 +0000

STMicroelectronics’ "ST op-amps" application allows you to select the appropriate operational amplifiers, comparators, high speed amplifiers and current sensing for your application using the product selector. Datasheets can be downloaded to provide more information about each parts.
The application provides additional information such as the most used schematics, compensation methods or package mechanical dimensions.

This application contains interactive schematics :
- inverting configuration
- non-inverting configuration
- low pass filter
- high pass filter
- differential configuration
- summing configuration
- comparator with hysteresis

Main features
- Op-amp product selector
- Comparator product selector
- High speed amplifier product selector
- Current sensing product selector
- Schematics library
- Interactive schematics
- Application notes
- Package mechanical drawings and data
- Links to ST website

Recent changes:
- New interactive schematics : low and high pass filters, differential and summing configurations, comparator with hysteresis
- Database update : New op-amp and comparator families have been added

NfcV-reader

Mon, 19 Nov 2012 23:19:30 +0000

The NfcV-reader is an NFC application for Android smart phone (NFC is mandatory to use it).

It allows to communicate with iso15693 products such as STMicroelectronics tags (LRIxx family) and Dual Interface EEPROM (M24LRxx family).

It also allows read and write NDEF message by using NFC features of Android OS. The NDEF message is a data format defined by NFC forum specification and offers interoperability of the different NFC devices.
NfcV-reader works with ISO/IEC 15693 and Dual Interface EEPROM contactless tag (Nfc-V on NFC forum).

Dual EE

Mon, 19 Nov 2012 23:25:19 +0000

The STMicroelectronics "Dual EE" application allows you to work with the M24LR64-R datalogger device*.
The application manage the NFC chip of the phone (read & write operations) in order to :
- Download data from the datalogger device*
- Save new settings to the datalogger device*

Main features :
- Start / Stop a temperature acquisition
- Download acquired temperatures from the datalogger device*
- Trace a graph of downloaded values (vertical & horizontal orientation)
- Display statistics (Max/Min/Avg Values - Histogram - etc…)
- Change settings (Frequency acquisition - Overwrite option)

If you don't have yet the datalogger device* you can :
- View a cover Flow presentation of the M24LR64-R product
- Access the STMicroelectronics website directly on the "Dual interface EEPROM" dedicated page.

datalogger device* : is an autonomous battery-powered datalogger able to record and store 64 Kbits of temperature data using the M24LR64-R Dual interface EEPROM (I2C and RF)

DatalogV3

Mon, 19 Nov 2012 23:25:19 +0000

This application allows your NFC phone to communicate with multi-sensor board “STEVAL-IPR002V1”.

It is able to :
- Download data from all of the sensors from the STEVAL-IPR002V1 board
- Display the sensor data on 6 different graphical curves

Main features :
- Start / Stop a sensor acquisition
- Download acquired data’s sensors from the STEVAL-IPR002V1 device
- Trace a graph of downloaded values (vertical & horizontal orientation)

The different kind of sensors is:
- Temperature Sensor
- Humidity Sensor
- Vibration
- Freefall
- Tamper
- Light

The STEVAL-IPR002V1 is an autonomous battery-powered datalogger able to record and store 64 Kbits of six different sensors data using the M24LR64-R Dual interface EEPROM (I2C and RF).

The M24LR64-R is a Dual Interface EEPROM which targets a wide range of applications such as industrial or medical equipment and consumer electronics. NFC compatible (ISO15693) and I2C serial communication are the two interfaces available with EEPROM”
