Features
■ True dual-ported memory cells which allow
simultaneous access of the same memory location
■ 32K x 16 organization (CY7C027V/027AV [1])
■ 64K x 16 organization (CY7C028V)
■ 32K x 18 organization (CY7C037AV)
■ 64K x 18 organization (CY7C038V)
■ 0.35 micron Complementary metal oxide semiconductor
(CMOS) for optimum speed and power
■ High speed access: 15, 20, and 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 32/36 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
■ Separate upper-byte and lower-byte control
■ Dual chip enables
■ Pin select for Master or Slave
■ Commercial and Industrial temperature ranges
■ 100-pin Pb-free Thin quad plastic flatpack (TQFP) and 100-pin
TQFP
Notes
1. CY7C027V, and CY7C027AV are functionally identical.
2. I/O8–I/O15 for x16 devices; I/O9–I/O17 for x18 devices.
3. I/O0–I/O7 for x16 devices; I/O0–I/O8 for x18 devices.
4. A0–A14 for 32K; A0–A15 for 64K devices.
5. BUSY is an output in master mode and an input in slave mode.
