Description
The Hitachi HN58S65A series is electrically erasable and programmable ROM organized as 8192-word
× 8-bit. It has realized high speed, low power consumption and high reliability by employing advanced
MNOS memory technology and CMOS process and circuitry technology. They also have a 64-byte
page programming function to make their write operations faster.
Features
Single supply: 2.2 to 3.6 V
Access time: 150 ns (max)
Power dissipation
Active: 10 mW/MHz (typ)
Standby: 36 µW (max)
On-chip latches: address, data, CE, OE, WE
Automatic byte write: 15 ms (max)
Automatic page write (64 bytes): 15 ms (max)
Ready/Busy
Data polling and Toggle bit
Data protection circuit on power on/off
Conforms to JEDEC byte-wide standard
Reliable CMOS with MNOS cell technology
105 erase/write cycles (in page mode)
10 years data retention
Software data protection
Industrial versions (Temperature range: – 40 to + 85˚C) are also available.
