5V, Byte Alterable EEPROM
Features
The Intersil X28C010/X28HT010 is a 128K x 8 EEPROM,
fabricated with Intersil's proprietary, high performance,
floating gate CMOS technology. Like all Intersil
programmable non-volatile memories, the
X28C010/X28HT010 is a 5V only device. The
X28C010/X28HT010 features the JEDEC approved pin out
for byte-wide memories, compatible with industry standard
EEPROMs.
• Access time: 120ns
• Simple byte and page write
- Single 5V supply
- No external high voltages or V control
PP
circuits
- Self-timed
• No erase before write
• No complex programming algorithms
• No overerase problem
The X28C010/X28HT010 supports a 256-byte page write
operation, effectively providing a 19µs/byte write cycle and
enabling the entire memory to be typically written in less
than 2.5 seconds. The X28C010/X28HT010 also features
DATA Polling and Toggle Bit Polling, system software
support schemes used to indicate the early completion of a
write cycle. In addition, the X28C010/X28HT010 supports
Software Data Protection option.
• Low power CMOS
- Active: 50mA
- Standby: 500µA
• Software data protection
- Protects data against system level inadvertent writes
• High speed page write capability
™
Intersil EEPROMs are designed and tested for applications
requiring extended endurance. Data retention is specified to
be greater than 100 years.
• Highly reliable Direct Write cell
- Endurance: 100,000 write cycles
- Data retention: 100 years
• Early end of write detection
- DATA polling
- Toggle bit polling
• X28HT010 is fuly functional @ +175°C
