DR021-0A 08/11/2001 IC41C16257/IC41C16257S IC41LV16257/IC41LV16257S .. 256K x 16 (4-MBIT) DYNAMIC RAM WITH FAST PAGE MODE Features - - - - - - - DESCRIPTION - - The ICSI IC41C16257 and the IC41LV16257 are 262,144 Fast access and cycle time x 16-bit high-performance CMOS Dynamic Random Access TTL patible inputs and outputs Memory. Fast Page Mode allows 512 random accesses Refresh Interval: 512 cycles/8 ms within a single row with access cycle time as short as 12 ns per 16-bit word. The Byte Write control, of upper and lower Refresh Mode: RAS-Only, CAS-before-RAS byte, makes these devices ideal for use in 16-, 32-bit wide (CBR), Hidden data bus systems. Self Refresh Mode: 512 cycles/64 ms (S version These Features make the IC41C16257 and the IC41LV16257 only) ideally suited for high band-width graphics, digital signal JEDEC standard pinout processing, high-performance puting systems, and peripheral applications. Single power supply: - 5V ± 10% (IC41C16257) The IC41C16257 and the IC41LV16257 are packaged in a 40-pin, 400mil SOJ and TSOP-2. - 3.3V ± 10% (IC41LV16257) Byte Write and Byte Read operation via KEY TIMING PARAMETERS two CAS Parameter -35 -50 -60 Unit Available in 40-pin SOJ and TSOP-2 Max.
