| 512Kx8 LP SRAM EM6112K800V Series GENERAL DESCRIPTION The EM6112K800V is a 4,194,304-bit low power CMOS static random access memory organized as 524,288 words by 8 bits. It is fabricated using very high performance, high reliability CMOS technology. Its standby current is stable within the range of operating temperature. The EM6112K800V is well designed for low power application, and particularly well suited for battery back-up nonvolatile memory application. The EM6112K800V operates from a single power supply of 2.7V ~ 3.6V and all inputs and outputs are fully TTL compatible FEATURES Fast access time: 45/55/70ns Low power consumption: Operating current: 40/30/20mA (TYP.) Standby current: -L/-LL version 20/2A (TYP.) Single 2.7V ~ 3.6V power supply All inputs and outputs TTL compatible Fully static operation Tri-state output Data retention voltage: 1.5V (MIN.)

Transition is measured 500mV from steady state. 5.At any given temperature and voltage condition, tCHZ is less than tCLZ , tOHZ is less than tOLZ. 6 DCC-SR-041005-A 512Kx8 LP SRAM EM6112K800V Series WRITE CYCLE 1 (WE# Controlled) (1,2,3,5,6) tWC Address CE# tAW tCW WE# tAS tWP tWR tWHZ Dout (4) tDW High-Z Din WRITE CYCLE 2 (CE# Controlled) (1,2,5,6) tWC Address CE# tAS tCW WE# tWP tAW Valid Data tOW (4) tDH tWR tWHZ Dout tDW High-Z Din Valid Data tDH High-Z Notes : 1. WE#, CE# must be high during all address transitions. 2. A write occurs during the overlap of a low CE#, low WE#. 3. During a WE# controlled write cycle with OE# low, tWP must be greater than tWHZ + tDW to allow the drivers to turn off and data to be placed on the bus. 4. During this period, I/O pins are in the output state, and input signals must not be applied. 5. If the CE# low transition occurs simultaneously with or after WE# low transition, the outputs remain in a high impedance state. 6. tOW and tWHZ are specified with CL = 5pF. Transition is measured 500mV from steady state. 7 DCC-SR-041005-A 512Kx8 LP SRAM EM6112K800V Series DATA RETENTION CHARACTERISTICS PARAMETER VCC for Data Retention Data Retention Current Chip Disable to Data Retention Time Recovery Time tRC* = Read Cycle Time SYMBOL VDR IDR TEST CONDITION CE# V VCC - 0.2V VCC = 1.5V CE# V VCC - 0.2V See Data Retention Waveforms (below) -L -LL -LLE -LLI MIN. 1.5 0 tRC* TYP. 1 0.5 0.5 MAX. 3.6 50 8 12 UNIT V A A A ns ns tCDR tR DATA RETENTION WAVEFORM VDR 1.5V Vcc Vcc(min.) tCDR CE# Vcc-0.2V Vcc(min.) tR VIH CE# VIH 8 DCC-SR-041005-A 512Kx8 LP SRAM EM6112K800V Series PACKAGE OUTLINE DIMENSION 32 pin 450 mil SOP Package Outline Dimension 32 pin 8mm x 20mm TSOP-I Package Outline Dimension 9 DCC-SR-041005-A 512Kx8 LP SRAM EM6112K800V Series 32 pin 8mm x 13.4mm STSOP Package Outline Dimension 10 DCC-SR-041005-A 512Kx8 LP SRAM EM6112K800V Series 36-ball 6mm x 8mm TFBGA Package Outline Dimension 11 DCC-SR-041005-A 512Kx8 LP SRAM EM6112K800V Series Product ID Information EM 61 12K 8 0 0 V B A - 45 IF* Configuration: Option 8: x8 Voltage: 16: x16 V: 3V W: 2.7V Address Density ~5.5V 12K: 512K EOREX T: 5V Package: Manufactured S: STSOP Memory P: PDIP F: SOP B: TFBGA T: TSOP I: TSOP-I * Product ID example SRAM Family 61: Standard Version Option Speed: 45ns 55ns 70ns TEMP: Blank: Normal I: Industrial Pb-Free PKG: Blank: Normal F: Pb-free 12 DCC-SR-041005-A 512Kx8 LP SRAM EM6112K800V Series (c)COPYRIGHT 2004 EOREX CORPORATION The information in this document is subject to change without notice.
