MC has new memory device, 4 Kbit, 5V, 47C04 EERAM & 47L16 16 Kbit, 3.3V EERAM
Quote...
The new I2C EERAM combines an SRAM with a shadow EEPROM back-up on a single chip to provide automatic data retention when system power is lost. This low-cost, low-risk solution also offers unlimited endurance and is capable of instant random writes with no write cycle delay.
These features benefit metering, automotive and industrial applications which need constant or instantaneous data monitoring, recording or updating, without the need for an external battery, to ensure safer data storage.
