Product details

Overview

24LC00-I/P 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 parameters. It operates from 2.5V to 5.5V, draws only 500 µA typical read current and 100 nA typical standby current, and supports 100 kHz/400 kHz clock rates in industrial temperature range (–40°C to +85°C).

For engineers reviewing the 24LC00-I/P datasheet, 24LC00-I/P pinout, 24LC00-I/P application, or 24LC00-I/P equivalent, this page delivers verified electrical specs, validated I²C timing compliance, confirmed PDIP-8 package mapping, and real-world use context for embedded system integration.

Technical Context

The 24LC00-I/P implements a true 2-wire I²C slave interface with Schmitt-trigger inputs and output slope control to suppress noise and eliminate ground bounce. Its internal address pointer enables current-address, random, and sequential read modes without external address latching.

Write operations are self-timed with a typical 3 ms page write cycle and automatic erase/write sequencing. The device includes V_CC threshold detection (1.5V min) to prevent corruption during brown-out conditions and supports ACK polling to determine write completion without fixed delays.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	128 bits (16 × 8), sufficient for small ID strings or calibration coefficients without over-provisioning
V_CC operating range	2.5V to 5.5V - compatible with 3.3V and 5V logic systems, excludes sub-2.5V operation unlike 24AA00
I²C clock support	100 kHz and 400 kHz - enables standard and fast-mode communication on shared buses
Write cycle time	Typical 3 ms - defines minimum interval between successive writes; no external wait states required
Endurance & retention	1 million erase/write cycles and >200 years data retention - suitable for field-deployed devices with infrequent updates
Standby current	100 nA typical - enables battery-powered operation for years in sleep mode

Pinout & Package

24LC00-I/P is supplied in an 8-lead plastic dual in-line package (PDIP) with 300-mil body width. Pin 1 is index-marked; leads are tin-plated, Pb-free, and RoHS compliant.

Pin	Circuit Role	Design Meaning
1	NC	No internal connection - must be left unconnected or tied to GND/V_CC per layout best practice
2	NC	No internal connection - electrically isolated; no routing or pull-up required
3	NC	No internal connection - unused pad; avoids accidental shorting in dense layouts
4	V_SS	Ground reference - primary return path for all internal circuitry and I/O leakage currents
5	SDA	Open-drain bidirectional data line - requires external pull-up resistor (2 kΩ for 400 kHz, 10 kΩ for 100 kHz)
6	SCL	Input-only serial clock - synchronizes all data transfers; Schmitt trigger ensures noise immunity
7	NC	No internal connection - floating; no signal integrity impact if left unconnected
8	V_CC	Power supply input - must be decoupled with ≥0.1 µF ceramic capacitor near the pin

Key Features

Feature	Design Value
Low-voltage I²C interface	Operates down to 2.5V - eliminates level-shifting in 3.3V microcontroller systems
Schmitt-trigger inputs	0.05×V_CC hysteresis on SDA/SCL - rejects bus noise spikes up to 50 ns without external filtering
Output slope control	Controlled SDA fall time - prevents ground bounce that could disrupt adjacent digital signals
ACK polling support	Enables dynamic write-complete detection - avoids fixed delays and maximizes I²C bus throughput
ESD protection	4 kV HBM - meets industrial handling requirements without additional transient protection

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial EEPROM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
24AA00-I/P	Lower V_CC min (1.8V), identical pinout and memory map - but higher standby current (1 µA max vs. 100 nA)	Better suited for battery-critical applications below 2.5V; less optimal for 3.3V/5V-only systems where ultra-low quiescent current is key	Select 24AA00-I/P only when sub-2.5V operation is mandatory; otherwise 24LC00-I/P offers superior standby efficiency at same cost
AT24C01C-PU	1 Kbit capacity (8× larger), same PDIP-8 package and I²C interface - but no V_CC brown-out protection and 3 µA max standby	Preferred when future firmware expansion or multi-parameter logging is anticipated; not drop-in due to different device address	Choose AT24C01C-PU if memory headroom is needed; verify I²C address conflict (0x50 vs. 0x50 for 24LC00) and update driver code

Compared with 24AA00-I/P and AT24C01C-PU, the 24LC00-I/P delivers the lowest standby current in its class while maintaining strict 2.5V–5.5V compatibility and integrated brown-out safety - making it optimal for cost-sensitive, power-aware industrial and medical designs where 128-bit storage suffices.

FAQ

What is the minimum V_CC required for reliable operation of the 24LC00-I/P?

The 24LC00-I/P requires a minimum V_CC of 2.5V for guaranteed operation across the full industrial temperature range (–40°C to +85°C). Below this voltage, the internal write/erase logic is disabled by the V_CC threshold detector to prevent data corruption. This distinguishes it from the 24AA00-I/P, which supports down to 1.8V.

Does the 24LC00-I/P support both 100 kHz and 400 kHz I²C clock speeds?

Yes, the 24LC00-I/P fully supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C operation across its specified V_CC range (2.5V–5.5V). AC timing parameters including T_HIGH, T_LOW, and T_AA are characterized for both speeds, enabling interoperability with diverse master controllers without speed negotiation.

How many write cycles can the 24LC00-I/P endure before failure?

The 24LC00-I/P is rated for more than 1 million erase/write cycles per memory location, with data retention exceeding 200 years at +85°C. This endurance is ensured through characterization (not 100% tested) and is sufficient for applications involving infrequent updates such as factory calibration or device provisioning.

What is the function of the NC pins on the 24LC00-I/P PDIP package?

The 24LC00-I/P PDIP package has four NC (No Connect) pins: pins 1, 2, 3, and 7. These pins have no internal connection and must remain unconnected in the PCB layout. They are not tied to V_CC, V_SS, or any internal node - leaving them floating poses no functional risk and simplifies routing.

Can the 24LC00-I/P be used in place of the 24C00-I/P?

No - the 24LC00-I/P and 24C00-I/P are not interchangeable. The 24C00-I/P requires a minimum V_CC of 4.5V and supports automotive temperature range (–40°C to +125°C), whereas the 24LC00-I/P operates from 2.5V and is rated only for industrial temperature. Substituting one for the other risks functional failure or reduced reliability.
