Chip Selection - Digital Timer w/ onboard EEPROM configuration storage, and timer reset trigger pin

Matt Survilo

I'm looking for an IC that I can communicate with over SPI or I2C.

I'd like to send it a specific delay value (5-10 minutes) which it will recall from EEPROM on startup. Watch a pin and if the pin changes levels it will start the timer. If the pin goes back to the default level the timer will reset. Ocassionally I may want to update the delay stored in the EEPROM. Any ideas for a single chip that could accomplish this without using an MCU?

Hi Matt,

I have paged our timer expert, however he is currently out of the office on travel. He will get back to you when available. I can also contact our timer marketing expert if needed.

Best,

Evan Su

Hi Matt,

Unfortunately we don't have timing device that can read EEPROM.

We do have some timer products that can generate a configurable time interval and do watch dog but they don't support EEPROM.
