The 8-pin DIP package is easy to interface to the BS2, BS2e, BS2sx, BS2p24/40, BS2pe and BS2px24. Features Low-power CMOS technology Maximum write current 3 mA at 5.5 V Maximum read current 400 A at 5.5 V Standby current 100 nA typical at 5.5 V 5 mS max write cycle time 1,000,000 erase/write cycles 2-wire serial interface, IC compatible 8-pin .300 DIP Package Compatible with all BASIC Stamp 2 and SX Modules Application Ideas Data storage Data tables Quick Start Circuit Parallax, Inc. 24LC128 ( 602-00013) 08/2005 v2.0 Page 1 of 5 Connecting and Testing Connect the 24LC128 as shown in the Quick Start Circuit, then use the appropriate demo program for your BASIC Stamp module to verify correct operation. If you are using an SX Microcontroller you will need to write or edit some existing IC code to access the EEPROM.
