Technical Details & Description

512 Kbit SPI EEPROM in an 8-TSSOP

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

At the 5.5V ceiling it stays compatible with legacy 5V SPI buses.

Write cycle timing and endurance context

The write cycle time is 5 ms per page or word. For a 512 Kbit device that means a full-chip rewrite takes on the order of a few seconds, which is typical for serial EEPROMs. This part is not a fast-logger memory; it is sized for parameter storage, calibration tables, and boot configuration that update infrequently.

Frequently asked questions

What is the difference between the AT25512-TH-B and the AT25512-TH-T?

The AT25512-TH-B ships in Tube packaging; the AT25512-TH-T ships in Tape & Reel (and Cut Tape / Digi-Reel). The silicon, the 8-TSSOP package, and all electrical ratings — 512 Kbit density, 20 MHz SPI, 1.8V to 5.5V supply, -40°C to 85°C — are identical between the two. The choice is purely a pick-and-place logistics decision.

What is the memory size and organization of the AT25512-TH-B?

The AT25512-TH-B is a 512 Kbit EEPROM organized as 64K x 8 bits (64 Kbytes).
