• Access time: 85 ns/100 ns (max)
• Power dissipation
• On-chip latches: address, data, CE, OE, WE
• Automatic byte write: 10 ms max
• Automatic page write (64 bytes): 10 ms max
• Ready/Busy (only the HN58C257A series)
• Data polling and Toggle bit
• Data protection circuit on power on/off
• Conforms to JEDEC byte-wide standard
• Reliable CMOS with MNOS cell technology
• 10
• 10 years data retention
• Software data protection
• Write protection by RES pin (only the HN58C257A series)
• Industrial versions (Temperatur range: −20 to 85°C and – 40 to 85°C) are also available.
• There are also lead free products.
