• Manufacturer Part Number: F25L16PA-100DG
• Description: 3V Only 16 Mbit Serial Flash Memory with Dual
• Manufacturer: ESMT [Elite Semiconductor Memory Technology Inc.]

ESMT
The software status register provides status on whether the flash
memory array is available for any Read or Write operation,
whether the device is Write enabled, and the state of the memory
Write protection. During an internal Erase or Program operation,
