W25Q32JWSSIM TR

Product Overview

The W25Q32JWSSIM TR from Winbond Electronics is a 32 Mbit non-volatile FLASH memory IC using a NOR architecture. It is organized as 4M x 8 and accessed through an SPI interface that supports Quad I/O, QPI, and DTR operation. The device is supplied in an 8-SOIC surface-mount package with a 0.209 in / 5.30 mm body width and operates from a 1.7 V to 1.95 V supply. Its specified clock frequency is 133 MHz, with a 6 ns access time and a 5 ms write cycle time for word or page operations. The specified operating temperature range is -40°C to 85°C (TA).

Key Features

• 32 Mbit non-volatile FLASH memory with NOR architecture
• 4M x 8 memory organization
• SPI interface supporting Quad I/O, QPI, and DTR modes
• 133 MHz clock frequency with 6 ns access time
• 5 ms write cycle time for word or page operations
• 1.7 V to 1.95 V supply voltage range
• 8-SOIC surface-mount package, 0.209 in / 5.30 mm width
• Specified operating temperature range of -40°C to 85°C (TA)

Applications

• Embedded systems that store program code or configuration data in non-volatile memory
• Devices that retain calibration values, lookup tables, or other parameter data across power cycles
• Surface-mount designs using SPI-connected NOR FLASH with Quad I/O, QPI, or DTR access

Design & Procurement Notes

For design, confirm that the host controller can operate with a 1.7 V to 1.95 V memory supply and supports the required SPI, Quad I/O, QPI, or DTR signaling. The 8-SOIC package requires a surface-mount footprint compatible with the 0.209 in / 5.30 mm body width. Timing budgets should account for the 133 MHz clock frequency, 6 ns access time, and 5 ms word or page write cycle. The -40°C to 85°C (TA) range should be checked against the final assembly thermal environment. When selecting the device for a specific memory map, consider the 32 Mbit capacity and 4M x 8 organization.
