R1RP0408DI Series
Wide Temperature Range Version
4M High Speed SRAM (512-kword × 8-bit)
REJ03C0114-0100Z
Rev. 1.00
Mar.12.2004
Description
The R1RP0408DI Series is a 4-Mbit high speed static RAM organized 512-k word × 8-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 36-pin plastic SOJ.
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: 130 mA (max)
• TTL standby current: 40 mA (max)
• CMOS standby current: 5 mA (max)
• Center VCC and VSS type pin out
• Temperature range: −40 to +85°C
