Description
The IDT7MMV4101 is a three megabit static RAM constructed on an
multilayer laminate substrate using three 3.3V, 128K x 8 (IDT71V124)
static RAMS encapsulated in a Ball Grid Array (BGA).
The IDT7MMV4101 is packaged in a plastic BGA. The BGA configu-
ration allows 119 leads to be placed on a package 14mm by 22mm. At a
maximum of 3.5mm high, this low-profile surface mount package is ideal
for ultra dense systems.
All inputs and outputs of the IDT7MMV4101 are LVTTL compatible and
operate from a single 3.3V supply. Full asynchronous circuitry requires
no clocks or refresh for operation and provides equal access and cycle
times for ease of use.
