IC with inbuilt counter and memory

Other Parts Discussed in Thread: MSP430FR2100

Hi ,

we want to develop small circuit which will store temperature data and number of autoclavable cycle.

is there any simple IC which has inbuilt counter and memory which will count autoclavable cycle and store in memory. using thermistor  and voltage divider we are going to calculate temperature and is it possible to store temperature data.

Regards,

Sayali

    Hi Sayali,

    TI does not offer a dedicated device that performs these functions, but our low-cost, low-power MSP430 family of 16-bit FRAM microcontrollers are perfectly suited for this type of application.

    The MSP430FR2100 is a good place to start.  It has an 8-channel, 10-bit ADC so it can measure the thermistor, calcualte the temperature and store the temperature and cycle information in its FRAM memory, which is a non-volatile memory.

    Because this is a microcontroller you will need to write some code and program this device to perform the ADC measurements and store data to FRAM.

    To develop the code you can use our Code Composer Studio, which is free.

    I would also recommend starting with one of our LaunchPad kits so you can prototype and develop some of your code before designing your own PCB.  The MSP430FR2311 Launchpad is a good one to use, since the code you develop on this device will run on the the MSP430FR2100.  You don't need a programming tool because the Launchpad has one on the PCB.

    The MSP430FR2100 is ~$0.25 in 1k quantity.

    Thanks Dennis ,
    I will check this controller. is there any IC specific to only counter and store data.
