Product details

512 Kbit SPI EEPROM in a compact 8-TSSOP

The Microchip AT25512-TH-T is a 512 Kbit serial EEPROM organized as 64K x 8 bits, accessed through an SPI interface at clock frequencies up to 20 MHz.

Write cycle time and endurance — what to expect

This is a typical figure for SPI EEPROMs in this density class; a page write completes in 5 ms, after which the next command can be issued. For designs requiring frequent parameter updates, confirm endurance against the application's write duty cycle.

Active lifecycle — no near-term obsolescence concern

The base product number AT25512 covers multiple package and reel variants.

Frequently asked questions

What are the alternatives or cross-references for AT25512-TH-T?

The closest functional second-source is the AT25512-TH-B, which is the same AT25512 die in a Tube package instead of Tape & Reel. For a smaller density, the AT25256B-SSHL-T offers 256 Kbit in a similar 8-pin SOIC package.
