IS66WVC2M16ALL
32Mb Async/Page/Burst CellularRAM 1.5
Overview
The IS66WVC2M16ALL is an integrated memory device containing 32Mbit Pseudo Static Random Access
Memory using a self-refresh DRAM array organized as 2M words by 16 bits. The device includes several
power saving modes : Reduced Array Refresh mode where data is retained in a portion of the array and
Temperature Controlled Refresh. Both these modes reduce standby current drain. The device can be
operated in a standard asynchronous mode and high performance burst mode. The die has separate power
rails, VDDQ and VSSQ for the I/O to be run from a separate power supply from the device core.
Features
Single device supports asynchronous , page,
and burst operation
Mixed Mode supports asynchronous write and
synchronous read operation
Dual voltage rails for optional performance
VDD 1.7V~1.95V, VDDQ 1.7V~1.95V
Asynchronous mode read access : 70ns
Interpage Read access : 70ns
Intrapage Read access : 20ns
Burst mode for Read and Write operation
4, 8, 16,32 or Continuous
Low Power Consumption
Asynchronous Operation < 25 mA
Intrapage Read < 18mA
Burst operation < 35 mA (@104Mhz)
Standby < 150 uA(max.)
Deep power-down (DPD) < 3uA (Typ)
Low Power Feature
Reduced Array Refresh
Temperature Controlled Refresh
Deep power-down (DPD) mode
Operation Frequency up to 104Mhz
Operating temperature Range
Industrial -40°C~85°C
Package: 54-ball VFBGA
