HM6216255HC

HM6216255HC Series 4M High Speed SRAM (256-kword × 16-bit) ADE-203-1196 (Z) Preliminary Rev. 0.0 Oct. 31, 2000 Description The HM6216255HC Series is a 4-Mbit high speed static RAM organized 256-k word × 16-bit. It has realized high speed access time by employing CMOS process (6-transistor memory cell) and high speed circuit designing technology. It is most appropriate for the application which requires high speed, high density memory and wide bit width configuration, such as cache and buffer memory in system. It is packaged in 400mil 44-pin plastic SOJ and 400-mil 44-pin plastic TSOPII. Features Single 5.0 Vsupply : 5.0 V ± 10 % Access time: 10 ns (max) Completely static memory  No clock or timing strobe required Equal access and cycle times Directly TTL compatible  All inputs and outputs Operating current: 170 mA (max) TTL standby current: 40 mA (max) CMOS standby current: 5 mA (max) : 1.2 mA (max) (L-version) Data retansion current: 0.8 mA (max) (L-version) Data retantion voltage: 2 V (min) (L-version) Center VCC and VSS type pinout Preliminary: The specification of this device are subject to change without notice.
