Pinouts :

STK11C48-N25I datasheet

Description :

The Simtek STK11C48 is a fast static RAM with a nonvolatile element incorporated in each static memory cell. The SRAMcan be read and written an unlimited number of times,while independent, nonvolatile data resides in the Nonvolatile Elements. Data transfers from the SRAMto the Nonvolatile Elements (the STORE operation), or from Nonvolatile Elements to SRAM(the  RECALL operation), take place using a software sequence. Transfers from the Nonvolatile Elements to the SRAM(the  RECALL operation) also take place automatically on restoration of power.

Block Diagram


1. 25ns, 35ns and 45ns Access Times
2. STORE to Nonvolatile Elements Initiated by Software
3. RECALL to SRAM Initiated by Software or Power Restore
4. 10mA Typical ICC at 200ns Cycle Time
5. Unlimited READ, WRITE and RECALL Cycles

AD404M42VT Datasheet PDF – 4M, CMOS Dynamic RAM

Part Number : AD404M42VT

Function : 4M, CMOS Dynamic RAM

Package : 26 Pin SOJ, 24 Pin TSOP Type

Manufacturers : ASCEND

Pinouts :

AD404M42VT datasheet


Description :

The device CMOS Dynamic RAM organized as 4,194,304 words x 4 bits with extended data out access mode. It is fabricated with an advanced submicron CMOS technology and designed to operate from a Single 3.3V oniy power supply. Low voltage operation is more suitable to be used on battery backup, portable electronic application. lt is packaged in JEDEC standard 26/24-pin plastic SOJ or TSOP(II).


1. Single 3.3V only power supply
2. High speed tRAC acess time : 50/60ns
3. Low power dissipation
(1)  Active mode : 432/396 mW (Mas)
(2)  Standby mode: 0.54 mW (Mas)
4. Extended – data – out(EDO) page mode access
5. I/O level: CMOS level (Vcc = 3.3V)
6. 2048 refresh cycle in 32 ms(Std.) or 128 ms(S-version)
