1.8V 4K/8K/16K x 16

MoBL^®Dual-Port Static RAM

• Full asynchronous operation

Features

• Automatic power-down

• True dual-ported memory cells that allow simultaneous

access of the same memory location

• Pin select for Master or Slave

• Expandable data bus to 32 bits with Master/Slave chip

select when using more than one device

• 4/8/16K × 16 organization

• High-speed access: 40 ns

• On-chip arbitration logic

• Ultra Low operating power

• Semaphores included to permit software handshaking

between ports

— Active: I_CC= 15 mA (typical) at 55 ns

— Active: I_CC= 25 mA (typical) at 40 ns

— Standby: I_SB3= 2 µA (typical)

• Input Read Registers and Output Drive Registers

• INT flag for port-to-port communication

• Separate upper-byte and lower-byte control

• Industrial temperature ranges

• Small footprint: Available in a 6x6 mm 100-pin

Lead(Pb)-free vfBGA

• Port-independent 1.8V, 2.5V, and 3.0V I/Os
