DESCRIPTION
The M28LV64 is an 8K x 8 low power Parallel EEPROM fabricated with SGS-THOMSON pro- prietary single polysilicon CMOS technology. The device offers fast access time with low power dis- sipation and requires a 2.7V to 3.6V power supply. TSOP28 (N) 8 x13.4mm SO28 (MS) 300 mils Note:* RB function is only available on the M28L V64.
