IS25LP032D-JBLA3

IS25LP032D-JBLA3 is a 32-Mbit SPI serial flash memory from ISSI (Integrated Silicon Solution, Inc.). It’s designed for non-volatile storage of firmware and data in embedded systems, with low-power operation.
Key points:
- Density and interface: 32 Mbit (4 MB) SPI flash; standard SPI interface and supports faster reads (and dual/quad IO reads on compatible modes).
- Voltage and temp: operates at 2.7–3.6 V; temperature range typically -40 to 85 °C (industrial grade variant).
- Organization and access: 256-byte page program; sector erases (commonly 4 KB), block erases (64 KB/256 KB), and full-chip erase.
- Features: fast read, deep power-down, hold and write-protect (WP#) options; status register to monitor WIP (write-in-progress).
- Package: commonly 8-pin options (e.g., SOIC8/USON); JBLA3 denotes the specific packaging/temperature option.
- Applications: boot code, firmware storage, and data logging in microcontroller and embedded systems.
