1MHz EEPROM series feature I2C interface and densities up to 1Mbit
October 18, 2012 // Julien Happich
Rohm Semiconductor released a series of high density and high speed EEPROMs. The line-up comes with densities of 512k and 1Mbit, with speeds to up to 1MHz.
All EEPROMs feature a double cell structure to eliminate accidental failures, and a double protection circuit to prevent writing errors. This makes them suitable memory solutions for a wide range of devices such as consumer, industrial and automotive applications. Rewriting is performed by passing electrons through a tunnel oxide film. This, however, causes deterioration of the film, eventually leading to memory failure where the memory cell data is locked at '1' and cannot be rewritten to.
Rohm’s double cell structure prevents this by allotting two cells for each memory bit, connected in an OR configuration so that the second cell is able to operate upon failure of the first. All LSIs become unstable during power ON and OFF: EEPROMs are even more susceptible to failure, making it impossible to even recover from one malfunction. In response to this, Rohm has integrated a double protection circuit consisting of a Power ON Reset (POR) block that resets during start-up and a Low Voltage Write Error Protection Circuit (LVCC) that prevents write operations and resets during low voltage conditions (LVCC and below).
Data can be rewritten up to 1.000.000 times and stored for 40 years. The new devices can be delivered in standard packages such as SO8 and TSSOP8. All control functions are available through two ports of the serial clock (SCL) and serial data (SDA).

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
