IS61C64AH General Description

The ICSI IS61C64AH is a very high-speed, low power, 8192-word by 8-bit static RAM. It is fabricated using ICSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields access times as fast as 15 ns with low power consumption.

When CE1 is HIGH or CE2 is LOW (deselected), the device assumes a standby mode at which the power dissipation can be reduced down to 250 W (typical) with CMOS input levels.

Easy memory expansion is provided by using two Chip Enable inputs, CE1 and CE2. The active LOW Write Enable (WE) controls both writing and reading of the memory.

The IS61C64AH is packaged in the JEDEC standard 28-pin, 300mil SOJ and 330mil SOP.

IS61C64AH Maximum Ratings

Symbol	Parameter	Value	Unit
V_TERM	Terminal Voltage with Respect to GND	0.5 to +7.0	V
T_BIAS	Temperature Under Bias	55 to +125	°C
T_STG	Storage Temperature	65 to +150	°C
P_T	Power Dissipation	1.0	W
I_OUT	DC Output Current (LOW)	20	mA

Notes: 1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

IS61C64AH Features

• High-speed access time: 15, 20, 25 ns
• Automatic power-down when chip is deselected
• CMOS low power operation - 450 mW (typical) operating - 250 W (typical) standby
• TTL compatible interface levels
• Single 5V power supply
• Fully static operation: no clock or refresh required
• Three state outputs
• Two Chip Enables (CE1 and CE2) for simple memory expansion
