[SOLVED] 256KB EEPROM equivalent to ATTINY45's EEPROM

[satheeshvelu]

Hi all,

I'm looking for an EEPROM device which is equivalent to ATMEL Tiny45 EEPROM.

I went through the datasheets and shortlisted these parts.

Microchip 24AA256, 24FC256, 24LC256
On Semi CAT25256, CAT24C256

Moreover I need help on finding the equivalent clock frequency as same as Tiny45.

Kindly need your suggestion to choose the right equivalent part.

Thanks,
Satheesh

25xxx using SPI interface (45xxx also)
24xxx using I2c
Have no idea what do you mean by "equivalent to ATMEL Tiny45 EEPROM"
Tiny45 is an mcu

Also your assumptions about memory sizes are wrong. Please pay also attention to the spelling of memory size units.

ATtiny45 has 256 Byte of EEPROM. The said I2C and SPI memories have a capacity of 256 kbit (kb) = 32 kByte (kB)

Yes. I was wrong. Tiny45's EEPROM is 256 Byte (or 2Kbit). I did choose an 2K EEPROM. However is there a way to define my own Slave address for the EEPROM or is there any EEPROM for which I can set my own Slave Address.

I have to choose between 50 to 5F as Slave address. Any suggestion?

Thanks.
