First serial EEPROMs to support VESA E-EDID 1.3
27 March 2002, DSP, Micros & Memory

Microchip has released the first serial EEPROM device to meet the VESA E-EDID 1.3 Standard for PC monitors, projectors and flat panel displays. The new 24LC22A and 24LCS22A serial EEPROMs offer manufacturers simple, cost-effective alternatives for plug-and-play applications in high-end displays. With a 256 x 8-bit dual-mode serial EEPROM, they implement both DDC1 and DDC2 operating modes. Additional features include an I2C compatible 2-wire serial interface and wide operating range 2,5 - 5,5 V. They come packaged in standard 8-lead PDIP and SOIC. Microchip's 24LCXXB and 24AAXX series serial EEPROMs now also have an additional SOT-23 package option 72% smaller than 8-lead SOIC devices. These 5-lead SOT-23 I2C range were designed using PMOS Electrically Erasable Cell process technology. Ranging in densities from 128 bits through 16 Kb, they operate down to 2,5 V, have active current of 1 mA and standby current of 1 µA (24AAXX supports operation down to 1,8 V).
