47L04-I/SN (MICROCHIP)
NVRAM, EERAM, 4 Кбит, 512 x 8бит, I2C, SOIC
The 47L04-I/SN from Microchip is a 4Kbit, I2C serial EERAM in 8 pin SOIC package. This SRAM with EEPROM backup is designed to support a bidirectional two-wire bus and data transmission protocol (I2C). It provides infinite read and write cycles to the SRAM while EEPROM cells provide high-endurance non-volatile storage of data. With an external capacitor, SRAM data is automatically transferred to the EEPROM upon loss of power. Data can also be transferred manually by using either the hardware store pin or software control. Upon power-up, the EEPROM data is automatically recalled to the SRAM. Recall can also be initiated through software control.
- VCC range from 2.7V to 3.6V, maximum clock frequency of 1MHz
- Internally organized as 512 x 8bits, store time is 8ms maximum
- Operating temperature range from -40°C to +85°C
- Non-volatile external event detect flag, infinite read and write cycles to SRAM
- More than one million store cycles to EEPROM
- Data retention is > 200 years, ESD protection is > 4000V
- Zero cycle delay reads and writes
- Cascadable up to four devices
- Schmitt trigger inputs for noise suppression
- Low power CMOS technology, 200µA active current typical & 40µA standby current (maximum)
