PRELIMINARY INFORMATION
OCTOBER 2014
16Mb LOW VOLTAGE,
ULTRA LOW POWER PSEUDO CMOS STATIC RAM
DESCRIPTION
The ISSI IS66WV1M16EALL and IS66/67WV1M16EBLL are
Features
High-Speed access time :
- 70ns ( IS66WV1M16EALL )
- 55ns (IS66/67WV1M16EBLL )
CMOS Lower Power Operation
high-speed,16M bit static RAMs organized as 1M words by
16 bits. It is fabricated using ISSI’s high performance CMOS
technology.
This highly reliable process coupled with innovative circuit
design techniques, yields high-performance and low power
consumption devices.
Single Power Supply
VDD =1.7V~1.95V( IS66WV1M16EALL )
When CS1# is HIGH (deselected) or when CS2 is LOW
(deselected), the device assumes a standby mode at which
the power dissipation can be reduced down with CMOS input
levels.
VDD =2.5V~3.6V (IS66/67WV1M16EBLL )
Three State Outputs
Easy memory expansion is provided by using Chip Enable and
Output Enable inputs. The active LOW Write Enable (WE#)
controls both writing and reading of the memory. A data byte
allows Upper Byte (UB#) and Lower Byte (LB#) access.
Data Control for Upper and Lower bytes
Lead-free Available
The IS66WV1M16 EALL and IS66/67WV1M16EBLL are
packaged in the JEDEC standard 48-ball mini BGA
(6mm x 8mm). The device is also available for die sales.

POWER UP INITIALIZATION
IS66WV1M16EALL and IS66/67WV1M16EBLL include an on-chip voltage sensor used to launch the power-up
initialization process. When VDD reaches a stable level at or above the VDD (min) the device will require 50μs
to complete its self-initialization process. During the initialization period, CS1# should remain HIGH. When initialize-
ation is complete, the device is ready for normal operation.

Notes:
1. Test conditions and output loading are specified in the AC Test Conditions and AC Test Loads (Figure 1) on page 5.
2. The internal write time is defined by the overlap of CS1#, UB#, LB# and WE# LOW, CS2 HIGH . All signals must be
in valid states to initiate a Write, but anyone can go inactive to terminate Write. The Data Input Setup and Hold timing are
referenced to the rising or falling edge of the signals that terminates the Write.
3. Tested with the load in Figure 2. Transition is measured ±100 mV from steady-state voltage. Not 100% tested.
4. tPWE > tHzWE + tSD when OE# is LOW.
5. Chip Select Active Time (both CS1# LOW and CS2 HIGH) must not be longer than tCMS of 15 us.

Notes:
1. PSRAM uses DRAM cell which needs a REFRESH action periodically to retain the information. This REFRESH
action is performed only when the device is not selected (Chip Select Pins are Disabled). A hidden REFRESH action
has to be executed by the device at least once every 15 μs of tCSM.
2. Figure 3a shows a timing example in which consecutive READ cycles for more than 15 us . This timing should be
avoided for proper REFRESH operation.
REFRESH operation can begin only during Chip Select pins are Disabled (CS1# is High and CS2 is Low ) for more than 5ns.
Example on how to avoid tCSM violation in Figure 3a is shown in Figure 3b.
3. Figure 4a shows a timing example in which a single WRITE operation is maintained for a period greater than 15 μs.
Since a proper REFRESH action cannot be performed during device is selected by Chip Select pins, information
stored in the device will not be retained if this timing occurs.
Figure 4b is a timing example of using CS1# signal toggling for proper the WRITE operation
