Features
True Dual-Ported memory cells which allow simulta-
neous access of the same memory location
4K/8K/16K/32K x 8 organizations
(CY7C0138AV/144AV/006AV/007AV)
4K/8K/16K/32K x 9 organizations
(CY7C0139AV/145AV/016AV/017AV)
0.35-micron CMOS for optimum speed/power
High-speed access: 20/25 ns
Low operating power
— Active: ICC = 115 mA (typical)
— Standby: ISB3 = 10 A (typical)
Fully asynchronous operation
Automatic power-down
Expandable data bus to 16/18 bits or more using Master/
Slave chip select when using more than one device
On-chip arbitration logic
Semaphores included to permit software handshaking
between ports
INT flag for port-to-port communication
Pin select for Master or Slave
Commercial and Industrial Temperature Ranges
Available in 68-pin PLCC (all) and 64-pin TQFP
(7C006AV & 7C144AV)
Pin-compatible and functionally equivalent to
IDT70V05, 70V06, and 70V07.
Notes:
1.
I/O0–I/O7 for x8 devices; I/O0–I/O8 for x9 devices.
2.
A0–A11 for 4K devices; A0–A12 for 8K devices; A0–A13 for 16K devices; A0–A14 for 32K devices;
3.
