ROHM began to supply non-volatile logic technology with the logic of calculation of IC samples

Semiconductor manufacturer ROHM Co., Ltd. (based in Kyoto), established the non-volatile logic IC technology, reliability, has started mass production stage. The use of non-volatile synchronous CMOS logic technology development of the 4 Pin calculation of non-volatile logic IC "BU70013TL". This product in June 2009 began to supply the sample (sample price: 500 yen), to collect the users evaluation, and AT89C2051-24SC datasheet and in October began to produce 200,000 of the scale of mass production. ROHM Co., Ltd. production will be the headquarters (Kyoto) to.

ROHM nonvolatile logic technology, the use of original stand-alone ROHM ferroelectric structure, so that the logic IC performance and AT89C2051-24SC price and reliability of non-fragile areas so register of non-volatile, has cut off the power supply can be maintained even if the data , after restart the power supply can continue to maintain the original state of the specialty. Although there are existing IC to cut off part of the power circuit power consumption of the method, but the circuit used for storing data can not be cut off the power for this non-volatile logic IC can be completely cut off the power, so standby power consumption zero.

ROHM successfully from May 2008 published in non-volatile logic technology, the continued further development of commercialization, mass production of the technology to ensure the production of the circuit when the reliability. In order to ensure the reliability of the ferroelectric structure components require specific reliability evaluation, however, install a dedicated circuit in the digital circuit, it will become the circuit area very large. The ROHM logical register in the nonvolatile transistor to install a number of characteristics evaluation of a simple circuit using the same time, using the original evaluation logic circuit debugging line, the development of the structure of ferroelectric components. As such, the circuit can control the minimum size, the structure of ferroelectric devices can also have specific reliability evaluation.

Use of this technology for electric meter or gas meter and AT89C2051-24SC suppliers and other measuring devices developed based on non-volatile logic 4 Pin calculated IC "BU70013TL", and has started to supply samples. As non-volatile logic technology at work, cut off the power but also to maintain the data, even if the circumstances when no backup battery power before the restart after the data value from the start of work is conducive to mechanical calculator, volume, exchange equipment .

In terms of power consumption, data storage calculated using an external EEPROM general IC, you need to write data in the EEPROM of each as 1mA, read out when 0.1mA (in EEPROM for the 1Kbit conditions) of the current. It takes time to write data, the power is cut off the data in the calculator can not continue to write in the EEPROM, the data will need to re-write. On the other hand, use of non-volatile ferroelectric IC logic element calculations, write or read data at the time only 0.01mA of current, and can write or read data at high speed, as long as the write-once after the power cut off Data on the line.

And because the default functions using 4bit parallel can also use the 4 pin non-volatile logic calculator.

Non-volatile logic technology to automatically cut off the power in standby, which can effectively reduce power consumption. Low-power embedded applications for IC technologies expand the portable device, white appliances, personal computers and other kinds of products.
