DESCRIPTION

The M28LV16 is a 2K x 8 low power Parallel EEPROM fabricatedwith SGS-THOMSON proprie- tary single polysilicon CMOS technology. The de- vice offers fast access time with low power dissipation and requires a 2.7V to 3.6V power supply. The circuit has been designed to offer a flexible microcontroller interface featuring both hardware and software handshaking with Data Polling and Toggle Bit. The M28LV16 supports 64 byte page write operation. ASoftware Data Protec- tion (SDP) is also possible using the standard JEDEC algorithm. PDIP24 (P) TSOP28 (N) 8 x 13.4mm PLCC32 (K) SO24 (MS) 300 mils Note:* RB function is offered only with TSOP28 package.
