| 24LC21A Description | | The 24LC21A is a 128 x 8-bit dual-mode Serial Electrically Erasable PROM designed to meet the plug-and-play requirements of today’s advanced monitors. The 24LC21A represents a simple, low-cost route to meeting the stringent standards for monitor identification since it completely implements both the DDCI™ and DDC2™ operating modes, including recovery to DDC1, as defined by the Video Electronics Standards Association. The 24LC21A, which is pin and function compatible with 24LC21, features a 2-wire serial interface bus (I2C™ compatible), both commercial and industrial temperature ranges, ESD protection > 4000V, and a wide voltage range (2.5V to 5.5V). The 24LC21A is available in standard 8-pin PDIP and SOIC packages. | | 24LC21A Vendor | | Microchip | | 24LC21A Categories | | | 24LC21A Datasheet and Application Notes | | | Parameter | Value | | Smart Card Support | No | | Max.
