LPDDR

Low Power Double Data Rate memory (LPDDR) is also called Mobile DDR (MDDR). This form of memory operates at 1.8 volts as opposed to the more traditional 2.5 volts and is commonly used in portable electronics. As with all DDR memory, the double data rate is achieved by transferring data on both clock edges of the device. The following table describes LPDDR in relation to interfacing with the OMAP3530 device.

Supported devices	Any JEDEC 209 compliant device
Supported Size	Up to 1 Gigabyte
Max Clock Speed	266 MHz* (see note 1)
Device Count	1 or 2* (see note 2)
Data Width (bits)	16 or 32

Note 1: Higher speed grades are supported due to inherent JEDEC LPDDR backwards compatibility
Note 2: 1 x16 LPDDR device is used for 16 bit LPDDR memory system. 1x32 or 2x16 LPDDR devices are used for a 32 bit LPDDR memory system.
