SAN FRANCISCO—STMicroelectronics NV Thursday (June 9) claimed a new memory density record, launching what it described as the first 2-Mbit serial EEPROM chip for write-intensive applications.
ST (Geneva) said the M95M02 allows designers to replace multiple EEPROMs with a single device and improve parameter management on printed-circuit-boards. This breakthrough will help save build costs and board size for consumer and industrial applications, such as TVs and monitors, flat panels, set-top boxes, printers, smart meters and equipment used in medical applications, according to the company.
The M95M02 provides ultra-high-density storage in the same package outline as lower density alternatives, ST said. It also has the same connections and an industry-standard SPI high-speed serial interface, allowing use as a direct replacement or upgrade in established system designs, according to the company.
The M95M02 can be operated at voltages as low as 1.8V and has a standby mode drawing less than 5uA, making it ideal for use in low-power or battery-operated equipment, according to ST. Additionally, the SPI interface enables fast communication at up to 5 MHz at 2.5 V, the company said.
A second new 2-Mbit device from ST, the M24M02, communicates via an industry-standard I2C high-speed interface, operating up to 1 MHz, ST said.
Both devices, built on ST's proprietary EEPROM process technology, are available in the SO8N package, allowing full footprint compatibility with lower equivalent memory densities, ST said.
The two new serial ICs join ST's EEPROM portfolio, which includes the M95 series (SPI) and M24 series (I2C), offering densities from 1 kbit to 1 Mbit, T said. The 2-Mbit density M95M02 and M24M02 in the SO8N package are sampling now, priced at $1.80 for 1,000 units, the company said. Alternative pricing options are available for larger quantities, the company said.
