External EEPROM and PIC16F87

[weg22]

Hi all,

I am currently using a PIC16F87 micro. I am acquiring data from a sensor via RS232 and would like to store this data in some small external IC package. I would need to store around 10 bytes of data per second for a minimum of 10-20 minutes. I plan on using an external EEPROM IC. My questions are:

(1) Is this the best solution? If so, can someone recommend a specific EEPROM chip? If not, can you recommend alternatives?
(2) I'm currently reading data from my sensor about 50-100 times a second. How much will writing to the external EEPROM slow this down?
(3) I'm guessing I would just use the write_eeprom command to send the data to an external EEPROM chip?

Thanks in advance,
weg

Consider using FRAM, they are much faster than EEPROM and don't wear out, available with I2C or SPI bus. Checkout www.ramtron.com for specifications. Search this forum for more details and drivers.
