ON Semiconductor N01S8x 1Mb Ultra-Low Power Serial SRAM offer high-speed performance and low power. They operate with a single chip select (CS) input and use a simple Serial Peripheral Interface (SPI) protocol. In SPI mode, a single data-in (SI) and data-out (SO) line is used along with the clock (SCK) to access data within the device. In DUAL mode, two multiplexed data-in/data-out (SIO0-SIO1) lines are used. In QUAD mode, four multiplexed data-in/data-out (SIO0-SIO3) lines are used with the clock to access the memory. These devices can operate over a wide temperature range of 40�C to +85�C and are available in a 8-lead TSSOP package.Features 128K x 8bitLow power supply range 1.7V to 2.2V (N01S818HA)2.5V to 5.5V (N01S830HA and N01S830BA)Very Low Typical Standby Current<1.0�A (N01S818HA)<4.0�A (N01S830HA and N01S830BA)<10.0mA operating currentSimple Serial Interface Single-bit SPI Access DUAL-bit and QUAD-bit SPI-like AccessFlexible operating modesWord ModePage ModeBurst Mode (Full Array)High frequency 20MHz read and write operationBuilt-in write protection (CS High)Unlimited write cyclesPbFree and RoHS CompliantApplications Patient monitor Smart meter Cardiac monitoring device Event recorder Alarm system MP3 interface for Automobiles Medical monitoring device Game controller IP camera buffer Battery charger Laser receiver system GPS offender tracking Programmable logic controller IP radio
