PMIC
i.MX6UL/i.MX6ULL SODIMM SOM supports
NXP’s
PF3001 PMIC for On-SOM power management. The PF3001 is a
Power Management Integrated Circuit (PMIC) designed specifically for always ON application with the NXP
i.MX6UL/i.MX6ULL application processors. Also i.MX6UL/i.MX6ULL SODIMM SOM can optionally support
NXP’s
PF3000 PMIC which supports Low power and Standby operation too.
The PF3001 PMIC provides all required power to i.MX6UL/i.MX6ULL CPU and all On SOM peripherals. This PMIC
supports up to three buck converters, six linear regulators, RTC supply and coin-cell charger. i.MX6UL/i.MX6ULL
CPU’s
I2C1 interface is used for PMIC programming. I2C address for PMIC is 0x08.
2.5
Memory
2.5.1
DDR3L SDRAM
i.MX6UL/i.MX6ULL SODIMM SOM by default supports 256MB DDR3L RAM memory in 16bit mode. To support this, it
uses one 256MB DDR3L SDRAM IC. This device operates at 1.35V voltage level. DDR3L IC is physically located on
topside of the SODIMM SOM. The RAM size can be expandable up to maximum of 1GB.
2.5.2
NAND Flash
The i.MX6UL/i.MX6ULL SODIMM SOM supports 256MB NAND Flash as default boot device. This is connected to GPMI
controller of the i.MX6UL/i.MX6ULL CPU and operates at 3.3 Voltage level. The NAND flash memory is physically
located on topside of the SODIMM SOM. The NAND Flash size is expandable.
