Product Overview
The 93LC66/SN is a 4kB MICROWIRE compatible serial Electrically Erasable Programmable Read-Only Memory (EEPROM) configured as x8 or x16-bit depending on the external logic of levels of the ORG pin. Advanced CMOS technology makes this device ideal for low power nonvolatile memory applications.
- Single supply with programming operation down to 2.5V
- Low-power CMOS technology
- 100μA Typical active read current at 2.5V
- 3μA Typical standby current at 2.5V
- Self-timed erase and write cycles
- Automatic ERAL before WRAL
- Power ON/OFF data protection circuitry
- Industry standard 3-wire serial I/O
- Device status signal during erase/write cycles
- Sequential read function
- 1000000 Erase/write cycles ensured
- Data retention <gt/>200 years
