Product details
Overview
24AA00-I/PG from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for low-voltage embedded storage of calibration data, device IDs, and manufacturing parameters. It operates from 1.8 V to 5.5 V, 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). Packaged in 8-lead PDIP, it targets space-constrained industrial control and sensor modules.
For engineers reviewing the 24AA00-I/PG datasheet, 24AA00-I/PG pinout, 24AA00-I/PG application, or 24AA00-I/PG equivalent, this page delivers verified electrical specs, validated I²C timing compliance, confirmed 5-pin functional mapping, and real-world use cases for calibration memory in battery-powered and low-power systems.
Technical Context
The 24AA00-I/PG implements a fixed 128-bit EEPROM array with no page buffer - all writes are byte-level and self-timed. Its I²C slave interface uses open-drain SDA/SCL pins with integrated Schmitt triggers and input filtering (50 ns spike suppression), enabling robust operation on noisy buses without external RC networks.
It features a hardwired 4-bit device address (1010b) with three "don't care" bits, yielding a single fixed slave address per device. Internal VCC threshold detection disables write logic below 1.5 V, preventing partial writes during brown-out conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 bits (16 × 8), sufficient for storing 16 bytes of calibration constants or unique identifiers |
| Supply voltage | 1.8 V to 5.5 V - enables direct interfacing with 1.8 V, 3.3 V, and 5 V microcontrollers without level shifters |
| Interface | I²C-compatible 2-wire bus - requires only two MCU GPIOs and pull-up resistors (10 kΩ @ 100 kHz) |
| Write endurance | 1 million erase/write cycles - supports frequent field updates in test equipment or firmware configuration |
| Data retention | 200 years at +85°C - ensures long-term validity of stored calibration data across product lifetime |
| Standby current | 100 nA typical - critical for battery-backed systems where quiescent power must be minimized |
| Write cycle time | 3 ms typical - enables rapid parameter updates without blocking host MCU for extended periods |
Pinout & Package
24AA00-I/PG 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 connection - electrically isolated; must remain unconnected on PCB |
| 2 | NC | No connection - electrically isolated; must remain unconnected on PCB |
| 3 | NC | No connection - electrically isolated; must remain unconnected on PCB |
| 4 | VSS | Ground reference - connects to system GND plane; required for stable internal biasing |
| 5 | SDA | Serial Data I/O - bidirectional open-drain line; requires external pull-up resistor to VCC |
| 6 | SCL | Serial Clock input - driven by master MCU; synchronizes all address/data transfers |
| 7 | NC | No connection - electrically isolated; must remain unconnected on PCB |
| 8 | VCC | Power supply - accepts 1.8–5.5 V; internal regulator enables consistent EEPROM operation across voltage range |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional down to 1.8 V - eliminates need for separate 5 V rail in modern ultra-low-power designs |
| Schmitt trigger inputs | 0.05 × VCC hysteresis on SDA/SCL - rejects noise spikes up to 50 ns, removing need for external filtering |
| Output slope control | Controlled SDA fall time - prevents ground bounce and EMI during high-speed transitions |
| ESD protection | 4 kV HBM - withstands handling and board-level electrostatic discharge without latch-up or damage |
| Factory programming | Available pre-programmed - reduces post-manufacturing test time for ID or calibration data loading |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24LC00-I/P | Requires minimum 2.5 V supply; identical pinout, timing, and memory map | Not suitable for 1.8 V systems; otherwise drop-in for 3.3 V/5 V designs with same footprint | Select if operating above 2.5 V and legacy 24LC00 qualification is required |
| AT24C01A-PU | 1 Kbit capacity (128 × 8); same 1.8–5.5 V range but higher standby current (1 µA typical) | Provides 8× more storage for multi-parameter calibration; larger die area may affect layout density | Choose when future expansion or additional configuration data is anticipated |
Compared with 24AA00-I/PG, the 24LC00-I/P offers identical functionality at higher voltage thresholds, while the AT24C01A-PU trades minimal power penalty for significantly greater storage - making both viable alternatives depending on voltage constraints and memory scalability needs.

FAQ
What is the minimum operating voltage for the 24AA00-I/PG?
The 24AA00-I/PG operates down to 1.8 V, with internal circuitry guaranteed functional across the full 1.8 V to 5.5 V range. Below 1.5 V, the VCC threshold detector disables write operations to prevent corruption - a safeguard confirmed in DS20001178J, Section 6.1.
Does the 24AA00-I/PG support standard I²C addressing and ACK polling?
Yes, the 24AA00-I/PG uses a fixed 7-bit slave address of 1010xxx (where xxx are "don't care" bits), and fully supports ACK polling to detect write completion - a feature explicitly documented in Section 7.0 of the datasheet for maximizing bus throughput.
Can the 24AA00-I/PG be used in place of the 24LC00-I/P?
No - the 24AA00-I/PG and 24LC00-I/P share pinout and protocol but differ in minimum supply voltage (1.8 V vs. 2.5 V). Substituting 24AA00-I/PG into a 24LC00-I/P design risks malfunction below 2.5 V; validation per DS20001178J Table "Device Selection" is required.
How many write cycles can the 24AA00-I/PG endure before failure?
The 24AA00-I/PG is rated for more than 1 million erase/write cycles, as specified in the Features section of DS20001178J. This endurance is ensured by characterization (not 100% tested), and applies across the full industrial temperature range.
Is the 24AA00-I/PG compatible with 400 kHz I²C bus speeds?
Yes, the 24AA00-I/PG supports clock frequencies up to 400 kHz when VCC ≥ 2.5 V, as defined in Table 1-2 (AC Characteristics) of DS20001178J. At 1.8 V ≤ VCC < 2.5 V, maximum clock rate is limited to 100 kHz.
