Mature NOR technology with strong data retention supports long-life products

Broad ecosystem support across MCUs, toolchains, and drivers shortens development

Packaging

Type 16-SOIC wide body, surface-mount

Material Molded epoxy package with copper leadframe; Pb-free finish; RoHS3 compliant

Size Body width 7.50 mm (0.295"); JEDEC standard outline for 16-SOIC. For exact body length, height, and lead dimensions, see the mechanical drawing in the datasheet

Pin configuration 16 leads total. Typical signal set includes:

- CS# (chip select), CLK/SCK (serial clock)

- IO0/DQ0 (MOSI), IO1/DQ1 (MISO), IO2/DQ2, IO3/DQ3 for Quad I/O

- WP# (write protect), HOLD#/RESET# (package-dependent)

- VCC (power), GND (ground)

- Remaining leads may be no connect (NC) depending on the package drawing

- Always verify exact pinout and pin functions in the datasheet for the JMLE package

Thermal characteristics Operating ambient -40°C to +105°C. Thermal resistance values depend on PCB layout and airflow; consult the datasheet’s thermal section for θJA/θJC and recommended board conditions
