R1RP0404D Series
4M High Speed SRAM (1-Mword × 4-bit)
REJ03C0116-0100Z
Rev. 1.00
Mar.12.2004
Description
The R1RP0404D is a 4-Mbit high speed static RAM organized 1-Mword × 4-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 and high density memory,
such as cache and buffer memory in system. The R1RP0404D is packaged in 400-mil 32-pin SOJ for high
density surface mounting.
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)
: 1.0 mA (max) (L-version)
Data retention current: 0.5 mA (max) (L-version)
Data retention voltage: 2.0 V (min) (L-version)
Center VCC and VSS type pin out
