IS25LP128F-JKLE

IS25LP128F-JKLE is a 128‑Mbit serial NOR flash memory from ISSI (IS25LP128F family). It provides non‑volatile storage for firmware and data in embedded systems and is accessed via an SPI interface.
Key points:
- Capacity and organization: 128 Mbit (16 MB) with 24‑bit addressing (byte addressable).
- Interface: standard SPI (and, in some variants, faster Dual/Quad I/O modes) with typical SPI timing options.
- Memory organization: 256‑byte pages; erase blocks (sector/block sizes vary by device; see datasheet for exact values).
- Operations: Read, Fast Read, Page Program, Sector/Block Erase, Chip Erase; supports Write Enable/Disable, status and protection registers, and Deep Power‑Down.
- Features: low power modes, suitable for wear‑centred embedded use, and a wide operating voltage range (consult datasheet for exact rails and timing).
- Packaging: JKLE indicates a specific package/temperature grade variant; confirm pinout and packaging in the datasheet.
Typical use: boot code storage, firmware updates, and data storage in microcontroller or FPGA systems. For exact electrical specs, timing, endurance, and pinout, refer to the IS25LP128F-JKLE datasheet.

Key features of IS25LP128F-JKLE (serial flash, 128 Mbit):

- Speed: Up to ~104 MHz clock for fast reads
- Organization: 256-byte page size; 4 KB sectors; 64 KB blocks; chip erase option
- Power: Deep power-down mode; low standby current
- Security/protection: Hardware write protection (WP#), sector/block protection features
- Operating temp: Industrial range (typical -40°C to 85°C)
- Package: 8-pin package (JKLE variant; standard SOIC-8 style)
Note: Exact features may vary by revision; consult the latest datasheet for complete specs and mode support.

IS25LP128F-JKLE uses an 8-pin SOIC (SOP-8) surface-mount package (lead-free variant).

- Pin count: 8 pins (8-pin package, e.g., SOIC-8)
- Function: 128-Mbit serial (SPI) flash memory. Pins provide VCC, GND, CS#, SCK, DI (MOSI), DO (MISO), WP#, and HOLD#. WP# and HOLD# are active-low control pins.

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
- About the company: ISSI is a US-based semiconductor company that designs and markets memory products (NOR flash and DRAM); it is a fabless memory company that outsources manufacturing to foundries.

IS25LP128F-JKLE is a 128‑Mbit serial NOR flash (SPI). Key applications: boot firmware storage and execute-in-place for MCUs/SoCs; firmware updates (including OTA) and external program/data memory for embedded systems; data logging/secure storage for IoT, industrial, and automotive electronics; and fast random-access non-volatile memory for network devices and consumer electronics.
