4.5.1

General purpose I/O (GPIO) DC parameters

Table 22 shows DC parameters for GPIO pads. The parameters in Table 22 are guaranteed per the

operating ranges in Table 9, unless otherwise noted.

4.5.2

DDR I/O DC electrical characteristics

The DDR I/O pads support DDR3/DDR3L, LPDDR2, and LPDDR3 operational modes. The DDR

Memory Controller (DDRMC) is designed to be compatible with JEDEC-compliant SDRAMs. The

DDRC supports the following memory types:

•

DDR3 SDRAM compliant to JESD79-3E DDR3 JEDEC standard release July, 2010

•

LPDDR2 SDRAM compliant to JESD209-2B LPDDR2 JEDEC standard release June, 2009

•

LPDDR3 SDRAM compliant to JESD209-3B LPDDR3 JEDEC standard release August, 2013
