Overview

EA2M is a EEPROM Serial 2-Mb SPI Low-Power device internally organized as 256Kx8 bits. This features a 256−byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the EA2M device. The device features software and hardware write protection, including partial as well as full array protection. OnChip ECC (Error Correction Code) makes the device suitable for high reliability applications. The EA2M device is designed for ultra−low power consumption, targeting real−time data logging applications, hearing aids and other medical devices and battery operated applications.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
