IS41C16105C IS41LV16105C 1Mx16 16MbDRAMWITHFASTPAGEMODE FEBRUARY2012 FEATURES DESCRIPTION TTL compatible inputs and outputs tristate I/O The ISSI IS41C16105C and IS41LV16105C are 1,048,576 x 16-bit high-performance CMOS Dynamic Random Access Refresh Interval: Memories. Fast Page Mode allows 1,024 random accesses 1,024 cycles/16 ms within a single row with access cycle time as short as 20 ns per 16-bit word. It is asynchronous, as it does not require a Refresh Mode: clock signal input to synchronize commands and I/O. RAS-Only, CAS-before-RAS (CBR), and Hidden These features make the IS41C16105C and IS41LV16105C JEDEC standard pinout ideally suited for high-bandwidth graphics, digital signal Single power supply: processing, high-performance computing systems, and 5V 10% (IS41C16105C) peripheral applications that run without a clock to synchronize 3.3V 10% (IS41LV16105C) with the DRAM. The IS41C/LV16105C is packaged in a 42-pin 400-mil SOJ Byte Write and Byte Read operation via two CAS and 400-mil 50/44-pin TSOP (Type II). o o Industrial Temperature Range -40 C to 85 C KEYTIMINGPARAMETERS Parameter -50 Unit Max.
