Microchip Technology 24LC024T-I/MNY

Overview

24LC024T-I/MNY from Microchip Technology Inc. is a 2 Kbit I²C-compatible serial EEPROM organized as 256 × 8-bit memory, operating from 2.5V to 5.5V with hardware write-protection via the WP pin. It supports up to 400 kHz clock rate, features 16-byte page write buffer, and delivers ≤5 ms write cycle time. It is used in embedded systems for storing calibration data, configuration settings, and device identifiers.

For engineers reviewing the 24LC024T-I/MNY datasheet, 24LC024T-I/MNY pinout, 24LC024T-I/MNY application, or 24LC024T-I/MNY equivalent, key selection criteria include voltage range (2.5–5.5 V), industrial temperature rating (–40°C to +85°C), hardware write-protect capability, I²C bus compatibility up to 400 kHz, and 8-pin MSOP package footprint.

Technical Context

The 24LC024T-I/MNY implements a standard two-wire I²C interface with open-drain SDA/SCL pins, Schmitt-trigger inputs, and internal slope control to suppress ground bounce. Its address decoding uses A0–A2 pins to support up to eight devices on a single bus.

It integrates a self-timed erase/write cycle with automatic page buffering (16 bytes), hardware write protection via dedicated WP pin, and built-in VCC threshold detection that disables writes below 1.5 V. Endurance exceeds 1 million cycles with >200-year data retention at 25°C.

FAQ

What is the maximum I²C clock frequency supported by the 24LC024T-I/MNY?

The 24LC024T-I/MNY supports up to 400 kHz I²C clock frequency when VCC ≥ 2.5 V. At lower voltages (not applicable per its 2.5–5.5 V spec), the max clock would drop to 100 kHz - but the 24LC024T-I/MNY is not rated below 2.5 V, so 400 kHz is its guaranteed maximum operational speed. This enables efficient parameter updates in time-sensitive embedded control loops.

Does the 24LC024T-I/MNY have hardware write protection, and how is it implemented?

Yes, the 24LC024T-I/MNY includes a dedicated hardware write-protect (WP) pin. When WP is tied to VCC, the entire 2 Kbit memory array is locked against write or erase operations - even during active I²C transactions. This feature is absent in the 24LC025 variant and is physically present only on 8-pin packages like the MSOP used in 24LC024T-I/MNY.

What package type is used for the 24LC024T-I/MNY, and what are its key mechanical dimensions?

The 24LC024T-I/MNY uses an 8-pin MSOP (Mini Small Outline Package) with 0.65 mm lead pitch. Its body measures 3.0 mm × 3.0 mm × 1.0 mm height, and it features gull-wing leads suitable for reflow soldering. This compact footprint supports high-density PCB layouts in space-constrained applications such as portable medical devices and IoT edge nodes.

How many devices can be connected on the same I²C bus using the 24LC024T-I/MNY?

Up to eight 24LC024T-I/MNY devices can be connected on a single I²C bus using the A0, A1, and A2 address pins to configure unique 7-bit slave addresses. Each pin must be hardwired to either VCC or VSS to set its logic level, allowing 2³ = 8 distinct combinations. This enables scalable memory expansion without additional address decoding logic.

What is the write endurance and data retention specification for the 24LC024T-I/MNY?

The 24LC024T-I/MNY guarantees more than 1 million erase/write cycles and greater than 200 years of data retention at 25°C. These specifications are validated through accelerated life testing and apply across its full industrial temperature range (–40°C to +85°C). The 24LC024T-I/MNY achieves this using Microchip's proven floating-gate EEPROM technology with robust oxide tunneling characteristics.
