CY7C1049CV33: 4-Mbit (512 K × 8) Static RAM

2015 年 8 月 19 日

4-Mbit (512K X 8) Static RAM


  • Temperature ranges
    • Commercial: 0°C to 70°C
  • High speed
    • tAA = 8 ns
  • Low active power
    • 360 mW (max)
  • 2.0 V data retention
  • Automatic power down when deselected
  • Transistor-transistor logic (TTL) compatible inputs and outputs
  • Easy memory expansion with CE and OE features


The CY7C1049CV33 is a high performance Complementary metal oxide semiconductor (CMOS) Static RAM organized as 524,288 words by eight bits. Easy memory expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and three-state drivers. Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A18).
