SST25WF040BT-40I/SN Microchip

SST25WF080B 8 Mbit 1.8V SPI Serial Flash All devices are RoHS compliant Features Single Voltage Read and Write Operations Product Description - 1.65-1.95V Serial Interface Architecture SST25WF080B is a member of the Serial Flash 25 - SPI Compatible: Mode 0 and Mode 3 Series family and feature a four-wire, SPI-compatible interface that allows for a low pin-count package which High Speed Clock Frequency occupies less board space and ultimately lowers total -40MHz system costs. SPI serial flash memory is manufactured Dual Input/Output Support with proprietary, high-performance CMOS SuperFlash - Fast-Read Dual-Output Instruction (3BH) technology. The split-gate cell design and thick-oxide - Fast-Read Dual I/O Instruction (BBH) tunneling injector attain better reliability and manufac- Superior Reliability turability compared with alternate approaches. - Endurance: 100,000 Cycles This Serial Flash significantly improve performance - Greater than 20 years Data Retention and reliability, while lowering power consumption. The device writes (Program or Erase) with a single power Ultra-Low Power Consumption: supply of 1.65-1.95V. The total energy consumed is a - Active Read Current: 4 mA (typical) function of the applied voltage, current, and time of - Standby Current: 7 A (typical) application. Since for any given voltage range, the - Deep Power-down Current: 2 A (typical) SuperFlash technology uses less current to program Flexible Erase Capability and has a shorter erase time, the total energy con- - Uniform 4 KByte sectors sumed during any Erase or Program operation is less than alternative flash memory technologies. - Uniform 64 KByte overlay blocks Page Program Mode SST25WF080B is offered in 8-lead SOIC and 8-contact USON packages. See Figure 2-1 for the pin assign- - 256 Bytes/Page ments. Fast Erase and Page-Program: - Chip-Erase Time: 500 ms (typical) - Sector-Erase Time: 40 ms (typical) - Block-Erase Time: 80 ms (typical) - Page-Program Time: 0.8 ms/ 256 bytes (typical) End-of-Write Detection - Software polling the BUSY bit in Status Register Hold Pin (HOLD#) - Suspend a serial sequence without deselecting the device Write Protection (WP#) - Enables/Disables the Lock-Down function of the status register Software Write Protection - Write protection through Block-Protection bits in status register Temperature Range - Industrial: -40C to +85C - Extended: -40C to +125C - AECQ-100 Qualified Packages Available - 8-lead SOIC (150 mils) - 8-contact USON (2mm x 3mm) 2013-2018 Microchip Technology Inc.
