Overview  
The Cypress CY14C101I/CY14B101I/CY14E101I combines a  
1-Mbit nvSRAM[1] with a full-featured RTC in a monolithic  
integrated circuit with serial I2C interface. The memory is  
organized as 128 K words of 8 bits each. The embedded nonvol-  
atile elements incorporate the QuantumTrap technology,  
creating the world’s most reliable nonvolatile memory. The  
SRAM provides infinite read and write cycles, while the  
QuantumTrap cells provide highly reliable nonvolatile storage of  
data. Data transfers from SRAM to the nonvolatile elements  
(STORE operation) takes place automatically at power-down.  
On power-up, data is restored to the SRAM from the nonvolatile  
memory (RECALL operation). The STORE and RECALL opera-  
tions can also be initiated by the user through I2C commands.  
❐ Industry standard 100 kHz and 400 kHz speed  
❐ Fast mode Plus: 1 MHz speed  
❐ High speed: 3.4 MHz  
❐ Zero cycle delay reads and writes  
■ Write protection  
❐ Hardware protection using Write Protect (WP) pin  
❐ Software block protection for 1/4, 1/2, or entire array
