Winbond Electronics Corporation W25X80VSSIG T&R

Overview

W25X80VSSIG T&R from Winbond is an 8M-bit (1MB) serial flash memory IC with SPI and dual-output SPI interface, organized into 4096 pages of 256 bytes each and 256 uniform 4KB sectors. It operates from 2.7V to 3.6V, supports up to 75MHz clock (150Mbps dual-output read), and delivers 100,000 program/erase cycles with 20-year data retention. It is used for code storage and parameter retention in space-constrained embedded boot systems.

For engineers reviewing the W25X80VSSIG T&R datasheet, W25X80VSSIG T&R pinout, W25X80VSSIG T&R application, or W25X80VSSIG T&R equivalent, key selection factors include its SOIC-208-mil (SS) package, hardware/software write protection via /WP and status register, sector-level erase granularity, dual-output read performance, and JEDEC-compliant identification support.

Technical Context

The W25X80VSSIG T&R implements a standard SPI Mode 0/3 interface with four dedicated pins: /CS, CLK, DIO (bidirectional), and DO (dedicated output). Its dual-output capability activates only during Fast Read Dual Output (3Bh) instruction, repurposing DIO as a second data output line to double throughput without requiring additional I/O lines.

Internal architecture includes a 256-byte page buffer, programmable block protect bits (BP2–BP0) with top/bottom selection (TB), and a non-volatile status register with SRP-controlled write lock. Write enable state (WEL) is automatically cleared after any program/erase/write-status operation, enforcing explicit re-enablement before subsequent writes.

FAQ

What is the package type and lead count of the W25X80VSSIG T&R?

The W25X80VSSIG T&R uses an 8-pin SOIC package with 208-mil width (Package Code SS), featuring gull-wing leads and surface-mount compatibility. Its dimensions are 5.3 mm × 5.3 mm × 1.9 mm, and it is supplied in tape-and-reel format per the "T&R" suffix. This package is distinct from the 150-mil SOIC used for lower-density W25X10/W25X20 variants.

Does the W25X80VSSIG T&R support dual-output read mode, and how is it enabled?

Yes, the W25X80VSSIG T&R supports dual-output read mode via the Fast Read Dual Output instruction (0x3B). When this command is issued, the DIO pin functions as a second data output alongside DO, doubling effective read throughput to 150 Mbps at 75 MHz clock. No configuration register setting is required - activation is instruction-driven and automatic during 0x3B execution.

How many program/erase cycles does the W25X80VSSIG T&R guarantee, and what is its data retention period?

The W25X80VSSIG T&R guarantees a minimum of 100,000 program/erase cycles per sector and 20 years of data retention at +25°C. Retention remains validated at 10 years at +85°C per manufacturer specifications, making it suitable for industrial and automotive applications where long-term data integrity is critical.

Can the W25X80VSSIG T&R be hardware write-protected, and which pins control this?

Yes, the W25X80VSSIG T&R supports hardware write protection using the /WP (pin 3) in conjunction with the Status Register Protect (SRP) bit. When SRP = 1 and /WP is driven low, writes to the status register - including block protect bit configuration - are disabled. This prevents unauthorized modification of memory protection settings during system operation.

What JEDEC identifiers does the W25X80VSSIG T&R report, and how are they read?

The W25X80VSSIG T&R reports Manufacturer ID = 0xEF and Device ID = 0x13 (16-bit ID = 0x3014) via the Release Power-down / Device ID instruction (0xAB) and Read Manufacturer/Device ID instruction (0x90). These values are fixed and factory-programmed, enabling unambiguous device identification in automated test and firmware initialization routines.
