Description
The R1RP0416D 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: 12 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: 160 mA (max)
TTL standby current: 40 mA (max)
CMOS standby current: 5 mA (max)
: 1.0 mA (max) (L-version)
Data retention current: 0.5 mA (max) (L-version)
Data retention voltage: 2 V (min) (L-version)
Center VCC and VSS type pin out
