IS62/65WVS5128GALL IS62/65WVS5128GBLL JULY 2021 512Kx8 LOW VOLTAGE, FAST SERIAL SRAM with SPI, SDI and SQI INTERFACE KEY FEATURES DESCRIPTION The ISSI IS62/65WVS5128GALL/GBLL are 4M bit Fast SPI-Compatible Bus Interface: Serial static RAMs organized as 512K bytes by 8 bits. It - 30/45 MHz Clock rate is a dual die stack of two 2Mb Serial SRAMs. - SPI/SDI/SQI mode The device is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals Single Power Supply: required are a clock input (SCK) plus separate data - VDD = 1.65V - 2.2V (IS62/65WVS5128GALL) in (SI) and data out (SO) lines. Access the device is - VDD = 2.70V - 3.6V (IS62/65WVS5128GBLL) controlled through a Chip Select (CS ) input. Additionally, SDI (Serial Dual Interface) and SQI Read Latency: (Serial Quad Interface) is supported if your application needs faster data rates. - SPI mode: 8 clocks - DPI mode: 4 clocks This device also supports unlimited reads and writes to the memory array. - QPI mode: 2 clocks Low-Power CMOS Technology: The IS62/65WVS5128GALL/GBLL are available in the standard 8-pin SOIC package. - Read Current: 20 mA(max) at 3.6V, 45 MHz, 85C - CMOS Standby Current: 8 A(typ) 512K x 8-bit Organization: - 32-byte page Byte, Page and Sequential mode for Reads and Writes Temperature Ranges Supported: - Industrial (I): -40C to +85C - Automotive (A3): -40C to +125C RoHS Compliant - 8-pin SOIC package Copyright 2020 Integrated Silicon Solution, Inc.
