ICSI IS61LV6424 64k x 24 high-speed cmos static ram with 3.3v supply Datasheet

IS61LV6424
64K x 24 HIGH-SPEED CMOS STATIC RAM
WITH 3.3V SUPPLY
FEATURES
• High-speed access time: 9, 10, 12, 15 ns
• CMOS low power operation
— 594 mW (max.) operating @ 9 ns
— 36 mW (max.) CMOS standby
• TTL compatible interface levels
• Single 3.3V power supply
• Fully static operation: no clock or refresh
required
• Three state outputs
• Available in 100-pin LQFP
DESCRIPTION
The ICSI IS61LV6424 is a high-speed, static RAM organized
as 65,536 words by 24 bits. It is fabricated using ICSI's highperformance CMOS technology. This highly reliable process
coupled with innovative circuit design techniques, yields access times as fast as 9 ns with low power consumption.
When CE1 is HIGH and CE2 is LOW (deselected), the device
assumes a standby mode at which the power dissipation can
be reduced down with CMOS input levels.
Easy memory expansion is provided by using Chip Enable and
Output Enable inputs, CE1, CE2, and OE. The active LOW
Write Enable (WE) controls both writing and reading of the
memory.
The IS61LV6424 is packaged in the JEDEC standard
100-pin 14*20*1.4mm LQFP.

Notes:
1. Test conditions assume signal transition times of 2 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V
and output loading specified in Figure 1.
2. Tested with the load in Figure 2. Transition is measured ±200 mV from steady-state voltage. Not 100% tested.

Notes:
1. Test conditions assume signal transition times of 2 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V
and output loading specified in Figure 1.
2. Tested with the load in Figure 2. Transition is measured ±200 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of CE1, LOW, CE2 HIGH and WE LOW. All signals must be in valid states
to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced
to the rising or falling edge of the signal that terminates the write.
