IS25LP040E-JNLE-TR

Product Overview

The IS25LP040E-JNLE-TR from ISSI, Integrated Silicon Solution Inc is a non-volatile NOR flash memory integrated circuit with 4 Mbit capacity organized as 512K x 8. It uses an SPI interface supporting Quad I/O, QPI, and DTR, and it is packaged in an 8-SOIC surface-mount case. The device operates from a 2.3 V to 3.6 V supply and is specified for a 104 MHz clock frequency, with an 8 ns access time and a 1.2 ms word or page write cycle time. Its operating temperature range is -40°C to 105°C (TA).

Key Features

• 4 Mbit non-volatile NOR flash memory with 512K x 8 organization.
• SPI interface supporting Quad I/O, QPI, and DTR.
• 104 MHz clock frequency, 8 ns access time, and 1.2 ms word or page write cycle time.
• 2.3 V to 3.6 V supply range.
• Surface-mount 8-SOIC package, 0.154 inch, 3.90 mm width.
• Operating temperature range of -40°C to 105°C (TA).

Applications

• Embedded firmware storage in SPI-connected systems.
• Configuration or calibration data storage in non-volatile memory designs.
• Memory expansion for designs using Quad I/O, QPI, or DTR communication.

Design & Procurement Notes

Design considerations include matching the 2.3 V to 3.6 V supply range, the 8-SOIC surface-mount footprint with 0.154 inch, 3.90 mm width, and the SPI - Quad I/O, QPI, DTR interface to the SPI host. The 512K x 8 organization and 4 Mbit capacity define the memory structure, while the 104 MHz clock, 8 ns access time, and 1.2 ms word or page write cycle time should be checked against system timing budgets. The -40°C to 105°C (TA) operating range and non-volatile NOR flash format should be considered for thermal and non-volatile memory requirements.
