256-Kbit (32 K × 8) Serial (I2C) nvSRAM
Features
■ 256-Kbit nonvolatile static random access memory (nvSRAM)
❐ Internally organized as 32 K × 8 ❐ STORE to QuantumTrap nonvolatile elements initiated
automatically on power-down (AutoStore) or by using I2C
command (Software STORE) or HSB pin (Hardware STORE)
❐
RECALL RECALL)
to or
SRAM initiated on power-up (Power-Up by I2C command (Software RECALL)
❐ Automatic STORE on power-down with a small capacitor (except for CY14MX256J1)
■ 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[1] ❐ 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
■ Low power consumption
❐ Average active current of 1 mA at 3.4-MHz operation ❐ Average standby mode current of 150 µA ❐ Sleep mode current of 8 µA
