512K X 16 Bit Low Voltage Super RAMTM
Features
n Operating voltage: 2.7V to 3.1V
n Access times: 70 ns (max.)
n Current:
n All inputs and outputs are directly TTL-compatible
n Common I/O using three-state output
n Industrial operating temperature range: -25°C to +85°C
for -I
A64S9316 series: Operating: 35mA (max.)
Power Down Standby: 10mA (max.)
n Available in 48-ball Mini BGA (6X8) package.
n Fully SRAM compatible operation
n Full static operation, no clock or refreshing required
General Description
The A64S9316 is a low operating current 8,388,608-bit
Super RAM organized as 524,288 words by 16 bits and
operates on low power supply voltage from 2.7V to 3.1V.
It is built using AMIC’s high performance CMOS DRAM
process.
Inputs and three-state outputs are TTL compatible and allow
for direct interfacing with common system bus structures.
The chip enable input is provided for POWER-DOWN,
device enable. Two byte enable inputs and an output enable
input are included for easy interfacing.
Using hidden refresh technique, the A64S9316 provides
a 100% compatible asynchronous interface.
This A64S9316 is suited for low power application such as
mobile phone and PDA or other battery-operated handheld
device.

Initialization
The A64S9316 is initialized in the power-on sequence according to the following.
1. To stabilize internal circuits, after turning on the power, a 350ms or longer wait time must precede any signal toggling.
2. After the wait time, it can be normal operation.

Notes: 1. Following power application, make CE2 and CE1 high level during the wait time interval.
2. After power on sequence, the normal operating CE2 must keep at high.

Avoid Timing
Following figures are show you an abnormal timing which
is not supported on Super RAM and their solution.
At normal operation, if your system have a timing which
sustain invalid states over 10ms at normal mode like
Figure 1. There are some guide line for proper operation
of Super RAM.
When your system have multiple invalid address signal
shorter than tRC on the timing which showed in Figure 1,
Super RAM need toggle the CE1 to “high” about “tRC”
(Figure 2).
