■ Industry standard configurations  
❐ Operating voltages:  
Features  
■ 256-Kbit nonvolatile static random access memory (nvSRAM)  
❐ Internally organized as 32 K × 8  
• CY14MC256J: VCC = 2.4 V to 2.6 V  
• CY14MB256J: VCC = 2.7 V to 3.6 V  
❐ STORE to QuantumTrap nonvolatile elements initiated  
automatically on power-down (AutoStore) or by using I2C  
command (SoftwareSTORE) orHSBpin(HardwareSTORE)  
• CY14ME256J: VCC = 4.5 V to 5.5 V  
❐ Industrial temperature  
❐ 8- and 16-pin small outline integrated circuit (SOIC) package  
❐ Restriction of hazardous substances (RoHS) compliant  
❐ RECALL to SRAM initiated on power-up (Power-Up  
RECALL) or by I2C command (Software RECALL)  
Overview  
❐ Automatic STORE on power-down with a small capacitor  
(except for CY14MX256J1)  
The  
Cypress  
CY14MC256J/CY14MB256J/CY14ME256J  
combines a 256-Kbit nvSRAM[1] with a nonvolatile element in  
each memory cell. The memory is organized as 32 K words of  
8 bits each. The embedded nonvolatile 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 (except for CY14MX256J1). On  
power-up, data is restored to the SRAM from the nonvolatile  
memory (RECALL operation). The STORE and RECALL  
operations can also be initiated by the user through I2C  
commands.  
■ High reliability  
❐ Infinite read, write, and RECALL cycles  
❐ 1 million STORE cycles to QuantumTrap  
❐ Data retention: 20 years at 85 C  
■ High speed I2C interface  
❐ 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 one quarter, half, or entire array  
■ I2C access to special functions  
❐ Nonvolatile STORE/RECALL  
❐ 8 byte serial number  
❐ Manufacturer ID and Product ID  
❐ Sleep mode
