Product details
Overview
24C00T-E/MNY from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for low-power, space-constrained applications requiring nonvolatile storage of calibration data, device IDs, or manufacturing traceability. It operates at 4.5–5.5 V, supports industrial and automotive temperature ranges (–40°C to +125°C), features Schmitt-trigger inputs, and delivers typical standby current of 100 nA and page write time of 3 ms.
For engineers reviewing the 24C00T-E/MNY datasheet, 24C00T-E/MNY pinout, 24C00T-E/MNY application, or 24C00T-E/MNY equivalent, this page provides verified electrical specs, validated SOT-23 pin mapping, confirmed automotive-grade thermal performance, and real-world use cases in sensor calibration and firmware configuration storage.
Technical Context
The 24C00T-E/MNY implements a slave-only I²C interface with fixed 4-bit device code '1010' and three don't-care address bits, enabling single-bus addressing without external hardware configuration. Its internal address pointer auto-increments during sequential reads and retains position after byte writes.
It integrates on-chip voltage threshold detection (3.8 V nominal) that disables erase/write logic below supply specification, ensuring data integrity during brown-out conditions. Noise immunity is achieved via Schmitt-trigger inputs and input filter spike suppression (≤50 ns), eliminating need for external RC filtering on SDA/SCL lines.

FAQ
What is the maximum I²C clock frequency supported by the 24C00T-E/MNY?
The 24C00T-E/MNY supports up to 400 kHz I²C clock frequency when operated within its specified 4.5–5.5 V supply range and automotive temperature grade. This allows efficient configuration loading in time-sensitive embedded systems without requiring protocol translation or clock stretching mitigation.
Does the 24C00T-E/MNY require external pull-up resistors on SDA and SCL lines?
Yes, the 24C00T-E/MNY requires external pull-up resistors on both SDA and SCL lines because its I/O pins are open-drain. For 400 kHz operation, a 2 kΩ pull-up to VCC is recommended; for 100 kHz, 10 kΩ is typical. These values ensure proper rise times and noise margin per I²C specification.
Can the 24C00T-E/MNY be used in automotive applications requiring AEC-Q100 qualification?
No - the 24C00T-E/MNY is not AEC-Q100 qualified. However, it is rated for the automotive temperature range (–40°C to +125°C) and meets key reliability metrics including 1 million write cycles and 200-year data retention, making it suitable for non-safety-critical automotive subsystems where formal AEC-Q100 is not mandated.
How does the 24C00T-E/MNY handle write operations during power loss?
The 24C00T-E/MNY incorporates an internal VCC threshold detector that disables erase/write logic if supply drops below 3.8 V. This prevents partial writes and data corruption during brown-out events, ensuring EEPROM integrity without requiring external power-fail detection circuitry.
Is the NC pin on the 24C00T-E/MNY's SOT-23 package required to be connected?
No, the NC (pin 4) on the 24C00T-E/MNY is a no-connect terminal with no internal bond. It may be left floating or tied to VSS for mechanical reinforcement, but it has no electrical function and must not be connected to any active signal or voltage rail.
