概要

Description

IS25WP128F-JKLE is a 128-Mbit serial flash memory from ISSI (IS25WP family). It offers high-speed SPI interfaces, including standard SPI and Quad I/O (QSPI) modes, for fast code and data storage. The device provides 16 MB of flash organized in 256-byte pages with sector/block erase (e.g., 4 KB, 32 KB, 64 KB blocks). Key features include write enable/disable, page/program operations, sector/block erases, status register (WIP/WEL), optional hardware write-protect, read and power-down modes, and low-power standby.
Voltage and packaging: typical operation around 2.7–3.6 V (exact range depends on variant); JKLE denotes a specific package type and temperature grade (consult the datasheet for exact details). Applications: boot firmware storage, firmware updates, code and data storage in embedded systems.
Note: for exact timing (clock speed, page size, erase times), voltage ranges, pinout, and package/temperature options, refer to the official ISSI IS25WP128F-JKLE datasheet.

Features

IS25WP128F-JKLE features (concise):
- 128 Mbit serial flash memory (16 MB effective).
- SPI-compatible interface with Dual I/O and Quad I/O (DQ0–DQ3) for higher throughput.
- 2.7–3.6 V supply (single‑voltage operation).
- 256‑byte page size; 3-byte addressing (no 4-byte addressing needed for 128 Mb).
- Read modes: standard, fast read, plus Dual/Quad I/O reads up to ~104 MHz.
- Erase options: 4 KB, 8 KB, 64 KB blocks; chip erase; suspend/resume supported.
- Endurance up to ~100,000 P/E cycles; data retention ~20 years.
- Deep power-down mode and low-power standby.
- Temperature range: -40 °C to 85 °C (industrial).
- Package: 8-pin (SO8) lead-free (JKLE variant).

Package

An 8-pin SOP (SO8) lead-free surface-mount package.

Pinout

- Pin count: 8 pins (8-pin package, JKLE code).
- Function: IS25WP128F-JKLE is a serial (SPI) 128-Mbit flash memory. It stores code/data and is accessed via SPI.
- Typical pinout (SOIC-8/JKLE):
1 = CS# (Chip Select, active low)
2 = DO/SO (Serial Data Output / MISO)
3 = WP# (Write Protect, active low)
4 = GND
5 = DI/SI (Serial Data Input / MOSI)
6 = CLK (Serial Clock)
7 = HOLD# (Hold, active low)
8 = VCC (Power)
- Key notes: WP# protects memory sectors; HOLD# suspends operation without power-down.

Manufacturer

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI)
- Company type: A US-based semiconductor company that designs and markets memory ICs (flash memory, DRAM, SRAM); primarily fabless, outsourcing fabrication.

Application

- Boot firmware storage for microcontrollers
- Secure storage (keys, config) and secure boot
- Firmware updates (FOTA) for embedded systems
- Data logging and archival in industrial/IoT
- External code/data storage for automotive, consumer electronics, wearables
- General external flash replacement for EEPROM in embedded systems
(IS25WP128F-JKLE is a 128-Mbit serial flash suitable for high-density firmware and data storage in mixed-signal and automotive/industrial environments.)
