HM6216255HC Series
4M High Speed SRAM (256-kword × 16-bit)
ADE-203-1196B (Z) Rev. 1.0 Nov. 30, 2001 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 400-mil 44-pin plastic SOJ and 400-mil 44-pin plastic TSOPII.
Features
· Single 5.0 V supply : 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 retention current: 0.8 mA (max) (L-version) · Data retention voltage: 2 V (min) (L-version) · Center VCC and VSS type pin out
