SST26VF032BEUI 32 Mbit Serial Quad I/O (SQI) Flash Memory with EUI-48 and EUI-64 Identifier - 64 KByte blocks, two 32 KByte blocks, and Features eight 8 KByte parameter blocks Factory-Programmed with EUI-48 and EUI-64 - Read Protection on top and bottom 8 KByte Globally Unique Identifier parameter blocks - Secure, read-only access in Serial Flash Security ID Discoverable Parameter (SFDP) table - One-Time Programmable (OTP) 2 KByte, Secure ID Single Voltage Read and Write Operations - 64 bit unique, factory pre-programmed identifier - 2.7-3.6V or 2.3-3.6V - User-programmable area Serial Interface Architecture Temperature Range - Nibble-wide multiplexed I/Os with SPI-like serial - Industrial: -40C to +85C command structure Automotive AECQ-100 Qualified - Mode 0 and Mode 3 Packages Available - x1/x2/x4 Serial Peripheral Interface (SPI) Protocol - 8-lead SOIJ (5.28 mm) High Speed Clock Frequency All devices are RoHS compliant - 2.7-3.6V: 104 MHz max - 2.3-3.6V: 80 MHz max Product Description Burst Modes - Continuous linear burst The Serial Quad I/O (SQI) family of flash-memory - 8/16/32/64 Byte linear burst with wrap-around devices features a six-wire, 4-bit I/O interface that allows for low-power, high-performance operation in a low pin-count Superior Reliability package. SST26VF032BEUI also support full command-set - Endurance: 100,000 Cycles (min) compatibility to traditional Serial Peripheral Interface (SPI) - Greater than 100 years Data Retention protocol. System designs using SQI flash devices occupy Low Power Consumption: less board space and ultimately lower system costs. - Active Read current: 15 mA (typical 104 MHz) All members of the 26 Series, SQI family are manufactured - Standby Current: 15 A (typical) with proprietary, high-performance CMOS SuperFlash Fast Erase Time technology. The split-gate cell design and thick-oxide tun- - Sector/Block Erase: 18 ms (typ), 25 ms (max) neling injector attain better reliability and manufacturability - Chip Erase: 35 ms (typ), 50 ms (max) compared with alternate approaches. Page-Program SST26VF032BEUI significantly improve performance and - 256 Bytes per page in x1 or x4 mode reliability, while lowering power consumption. These devices End-of-Write Detection write (Program or Erase) with a single power supply of 2.3- 3.6V. The total energy consumed is a function of the applied - Software polling the BUSY bit in status register voltage, current, and time of application. Since for any given Flexible Erase Capability voltage range, the SuperFlash technology uses less current - Uniform 4 KByte sectors to program and has a shorter erase time, the total energy - Four 8 KByte top and bottom parameter overlay consumed during any Erase or Program operation is less blocks than alternative flash memory technologies. - One 32 KByte top and bottom overlay block SST26VF032BEUI is offered in 8-lead SOIJ (5.28 mm). - Uniform 64 KByte overlay blocks See Figure 2-1 for pin assignments. Write-Suspend SST26VF032BEUI default at power-up has the WP - Suspend Program or Erase operation to access and HOLD pins enabled, and the SIO2 and SIO3 another block/sector pins disabled, to initiate SPI-protocol operations.See Software Reset (RST) mode I/O Configuration (IOC) on page 11 for more Software Write Protection information about configuring WP /HOLD and SIO2/ - Individual-Block Write Protection with permanent SIO3 pins. lock-down capability 2019 Microchip Technology Inc.
