CYDM256B16
1.8 V 4 K/8 K/16 K × 16
MoBL® Dual-Port Static RAM
1.8V 4K/8K/16K x 16 MoBL® Dual-Port Static RAM
Features
■ True dual ported memory cells that allow simultaneous access
of the same memory location
■ 4, 8, or 16K × 16 organization
■ Ultra Low operating power
❐ Active: ICC = 15 mA (typical) at 55 ns
❐ Standby: ISB3 = 2 A (typical)
■ Small footprint: available in a 6x6 mm 100-pin Pb-free vfBGA
■ Port independent 1.8V, 2.5V, and 3.0V I/Os
■ Full asynchronous operation
■ Automatic power down
■ Pin select for Master or Slave
■ Expandable data bus to 32-bits with Master or Slave chip select
when using more than one device
■ On-chip arbitration logic
■ Semaphores included to permit software handshaking
between ports
■ Input read registers and output drive registers
■ INT flag for port-to-port communication
■ Separate upper-byte and lower-byte control
■ Industrial temperature ranges

Notes
21. fMAX = 1/tRC = All inputs cycling at f = 1/tRC (except output enable). f = 0 means no address or control lines change. This applies only to inputs at CMOS level standby ISB3.
