IS62/65WVS1288GALL IS62/65WVS1288GBLL JULY 2021 128Kx8 LOW VOLTAGE, FAST SERIAL SRAM with SPI, SDI and SQI INTERFACE KEY FEATURES DESCRIPTION SPI-Compatible Bus Interface: - 30/45 MHz Clock rate The ISSI IS62/65WVS1288GALL/GBLL are 1M bit Fast - SPI/SDI/SQI mode Serial static RAMs organized as 128K bytes by 8 bits. It is fabricated using ISSI s high-performance CMOS Single Power Supply: technology. - VDD = 1.65V - 2.2V (IS62/65WVS1288GALL) The device is accessed via a simple Serial Peripheral - VDD = 2.70V - 3.6V (IS62/65WVS1288GBLL) Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data Read Latency: in (SI) and data out (SO) lines. Access the device is - SPI mode: 8 clocks controlled through a Chip Select (CS ) input. Additionally, SDI (Serial Dual Interface) and SQI - DPI mode: 4 clocks (Serial Quad Interface) is supported if your application - QPI mode: 2 clocks needs faster data rates. Low-Power CMOS Technology: This device also supports unlimited reads and writes to - Read Current: 10 mA(max) at 3.6V, 45 MHz, 85C the memory array. - CMOS Standby Current: 4 A(typ) The IS62/65WVS5128GALL/GBLL are available in the standard 8-pin SOIC package. 128K 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 2021 Integrated Silicon Solution, Inc.
