Product Summary
The 24lc21at/sn is a 128 x 8-bit dual-mode Electrically Erasable PROM. The 24lc21at/sn is designed for use in applications requiring storage and serial transmission of configuration and control information. Two modes of operation have been implemented: Transmit-Only mode and Bidirectional mode. Upon power-up, the 24lc21at/sn will be in the Transmit-Only mode, sending a serial bit stream of the memory array from 00h to 7Fh, clocked by the VCLK pin.
Parametrics
24lc21at/sn absolute maximum ratings: (1)VCC: 7.0V; (2)All inputs and outputs w.r.t. VSS: -0.6V to VCC +1.0V; (3)Storage temperature : -65°C to +150°C; (4)Ambient temperature with power applied: -40°C to +125°C; (5)ESD protection on all pins : ≥ 4 kV.
Features
24lc21at/sn features: (1)Single Supply with Operation Down to 2.5V; (2)Pin and Function Compatible with 24LC21; (3)Low-Power CMOS Technology; (4)2-Wire Serial Interface Bus, I2C Compatible; (5)100 kHz (2.5V)and 400 kHz (5V)Compatibility; (6)Self-Timed Write Cycle (including auto-erase); (7)Page Write Buffer for up to Eight Bytes; (8)1,000,000 Erase/Write Cycles Ensured; (9)Data Retention > 200 years; (10)ESD Protection > 4000V; (11)8-pin PDIP and SOIC Package.
