Why this automotive EEPROM exists — the AEC-Q100 qualification
The STMicroelectronics M24C08-DRDW8TP/K is an 8 Kbit serial EEPROM organized as 1K x 8, communicating over an I²C bus at up to 1 MHz with a 450 ns access time. The 1.8V to 5.5V supply range means it runs directly off the vehicle's battery rail or a 3.3V/5V regulator without a separate supply.
I²C bus timing — 1 MHz clock with 450 ns access
The I²C interface runs at 1 MHz, which is fast-mode-plus speed. If your MCU's I²C peripheral tops out at 400 kHz standard mode, the part works there too — the 1 MHz rating is the ceiling, not the floor.
8-TSSOP package — rework and footprint notes
Housed in an 8-TSSOP (4.40 mm body width), this is a fine-pitch but hand-solderable package. The 0.65 mm lead pitch is standard for TSSOP-8; the footprint matches the JEDEC MO-153 pattern. No exposed pad, so no thermal-via stencil required.
ST lists this part as Active (current production). That means no last-time-buy deadline to manage, no risk of a sudden EOL notice for new designs. For dual-source planning, the M24C08 family is widely second-sourced by other manufacturers with pin-compatible parts — but verify the specific AEC-Q100 grade and temperature range against your BOM's requirements.
Sourcing this part for your BOM
The M24C08-DRDW8TP/K is an active, automotive-qualified part that ST continues to manufacture. No LTB risk, no broker scavenger hunt — this is a straightforward production BOM line.
