• Manufacturer Part Number: lrs1331
• Description: Stacked Chip Flash Memory Sram
• Manufacturer: Sharp Microelectronics of the Americas

Stacked Chip (16M Flash & 4M SRAM)
Write Cycle (F-CE Controlled)
NOTES:
1. In system where F-CE defines the pulse width (within a F-WE timing waveform), all setup,
2. Refer to the ‘Flash Memory Command Definition’ section for valid A
Block Erase and Word Write Performance
NOTES:
1. Reference values at T
2. Sampled, but not 100% tested.
3. Excludes system-level overhead.
