Behavioural mixed-signal modelMT41K256M16TW-107mt41k256m16tw
DDR3L SDRAM 4 Gbit (MT41K256M16TW)
DDR3L SDRAM, 4 Gbit (512 MB), 16 bit wide, 1.35 V, DDR3-1866 grade, 96-ball FBGA. Memory of an application processor (STM32MP1: DDR controller at 533 MHz). Address, bank and command lines must reach the matching balls; data bits may be swapped inside a byte lane and the lanes swapped. VDD and VDDQ 1.35 V, VREFCA / VREFDQ at VDDQ/2, ZQ with 240 Ω 1 % to GND. Symbol in two units: data, address / power.
