HM62256ALP-70G 8-Bit High Speed CMOS Static RAM 28-Pin PDIP

Description

32,768-word ×8-bit High-Speed CMOS Static RAM The HM62256 is a high performance, high speed and super low power CMOS Static Random Access Memory organized as 32,768 words by 8bits and operates for a single 4.5 to 5.5V supply voltage. Advanced CMOS technology and circuit techniques provide both high speed, super low power features and maximum access time of 55/70ns in 5.0V operation. Easy memory expansion is provided by an active LOW chip enable (/CE) and active LOW output enable (/OE). The HM62256 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The HM62256 is available in JEDEC standard 28-pin PDIP (600 mil) packages. Features Wide operation voltage : 4.5 ~ 5.5V Ultra low power consumption : 2mA＠1MHz (Max.) , Vcc=5.0V. 1.0 uA (Typ.) CMOS standby current High speed access time : 70ns. Automatic power down when chip is deselected. Three state outputs and TTL compatible. Data retention supply voltage as low as 2.0V. Easy expansion with /CE and /OE options. Specifications Minimum VSS VT Voltage: -0.5 V Maximum VSS VT Voltage: Vcc+0.5V Supply voltage range: 4,5~5,5V (Vcc=5V) RAM: 32kB PT power dissipation: 1W Access time: 70ns Minimum operating temperature: 0°C Maximum operating temperature: 70°C Circuit: CMOS Encapsulation: DIP 28 pin Datasheet
