STMicroelectronics has developed a new memory with a unique ultra-fast recording feature for storing important data during unexpected events. Its uses will include recovering system data when a sudden power failure occurs, as well as ‘black-box’ recorders that help identify the causes of equipment failures or accidents.
A system using the M35B32 EEPROM is able to store a significant amount of vital information (2 Kbits) in less than one millisecond, and hence can react when the onset of a system failure or an accident is detected. In cases such as a power failure, this super-fast data storage can save the information needed to recover the system before the power supply voltage falls to an unusable level. Major applications for this high-speed memory include games, battery powered gadgets, utility meters, smart-grid equipment, industrial systems and medical devices.
Compared to alternative non-volatile memories, the M35B32 is about 40 times faster than a standard 32 Kbit EEPROM and matches the write speed of Flash. Consuming approximately one-tenth the energy of Flash, ST’s new memory allows designers to specify a voltage supply backup capacitor of one-tenth the size needed to operate the memory long enough to finish writing if system power is lost unexpectedly.
The M35B32 has a 32 Kbit capacity, which is divided into two sectors for event recording and regular system EEPROM. The sector sizes are user adjustable to suit various application requirements. The large page size of 256 Bytes allows a large amount of data to be written in a single page-write cycle and, when addressing the event recording sector, this information can be programmed in less than 1 ms. The chip is accessed via a standard SPI serial connection and so can be used as a direct replacement for standard SPI serial memories.
