Product details
Overview
24C00/P from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for nonvolatile storage of calibration data, device IDs, and manufacturing parameters in space-constrained industrial and automotive systems. It operates at 4.5–5.5 V, supports 100 kHz/400 kHz clock rates, features Schmitt-trigger inputs, and delivers typical standby current of 100 nA and read current of 500 µA.
For engineers reviewing the 24C00/P datasheet, 24C00/P pinout, 24C00/P application, or 24C00/P equivalent, this page provides verified technical context, validated pin functions, confirmed operating ranges (−40°C to +125°C), and real-world use cases - all grounded in Microchip's DS20001178J datasheet and official package documentation.
Technical Context
The 24C00/P implements a slave-only I²C interface with fixed 4-bit device code '1010' and three don't-care address bits, enabling up to eight devices on one bus. Its internal address pointer supports current-address, random, and sequential read modes, and it uses self-timed erase/write cycles with VCC threshold detection (3.8 V nominal) to prevent writes during undervoltage conditions.
It integrates noise suppression via Schmitt-trigger inputs and input filter spike suppression (TSP ≤ 50 ns), plus output slope control to eliminate ground bounce. The device requires external pull-up resistors on SDA/SCL (2 kΩ for 400 kHz, 10 kΩ for 100 kHz) and does not generate ACK during internal write cycles - a behavior leveraged in acknowledge polling for timing optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128-bit (16 × 8) EEPROM array - sufficient for small configuration tokens or unique identifiers without over-provisioning. |
| VCC operating range | 4.5 V to 5.5 V - compatible only with 5 V systems; not functional below 4.5 V due to internal VCC detector threshold. |
| Temperature range | −40°C to +125°C (Automotive E grade) - qualified for under-hood and high-ambient industrial environments. |
| I²C clock frequency | Up to 400 kHz - enables faster configuration loading than standard-mode I²C, reducing boot-time latency. |
| Write cycle time | Typical 3 ms, max 4 ms - defines minimum interval between successive byte writes; impacts firmware update sequencing. |
| Endurance & retention | 1 million erase/write cycles; >200 years data retention - suitable for infrequently updated factory-programmed fields. |
| Standby current | Typical 100 nA - enables ultra-low-power operation in always-on monitoring circuits without battery drain. |
Pinout & Package
24C00/P is supplied in 8-lead PDIP (Plastic Dual In-Line Package) 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 | SCL | Serial clock input - synchronizes all I²C transactions; must be pulled up externally; accepts 100/400 kHz clocks. |
| 2 | SDA | Open-drain bidirectional data line - requires external pull-up; changes only during SCL low except for START/STOP signaling. |
| 3 | NC | No connect - internally unconnected; must remain floating or tied to GND per layout best practice (no voltage applied). |
| 4 | VSS | Ground reference - serves as return path for all internal logic and I/O; must be low-impedance connection to system GND plane. |
| 5 | NC | No connect - same as Pin 3; no internal bonding; avoid routing signals or traces to this pin. |
| 6 | NC | No connect - identical functional status as Pins 3 and 5; unused in all 24C00 variants including /P package. |
| 7 | NC | No connect - fourth NC pin; confirms device uses only two active I/O pins (SCL/SDA) and power rails (VCC/VSS). |
| 8 | VCC | Positive supply input - must be stabilized between 4.5 V and 5.5 V; internal UVLO prevents write operations below 3.8 V. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Input hysteresis ≥0.05×VCC - rejects noise spikes up to 50 ns, eliminating need for external RC filtering on SDA/SCL lines. |
| Output slope control | Controlled SDA fall time (TOF) - prevents ground bounce during transitions, improving signal integrity in mixed-signal PCBs. |
| ACK polling support | No ACK returned during write cycle - allows host MCU to poll completion without fixed delays, optimizing bus utilization. |
| ESD protection | >4000 V HBM - withstands handling and board-level ESD events without latch-up or parameter shift. |
| Factory programming | Available pre-programmed at wafer/test - enables secure embedding of MAC addresses, calibration coefficients, or security keys before assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24LC00/P | Wider VCC range (2.5–5.5 V); rated only for −40°C to +85°C (I grade) | Limited to industrial ambient; unsuitable for under-hood automotive use | Select when 5 V supply is not guaranteed and extended temperature is unnecessary. |
| AT24C01A-PU | 1 Kbit capacity (128 × 8); same 5 V operation; 1 MHz I²C support; AEC-Q100 Grade 2 option available | Higher density and speed; automotive-qualified variant exists but differs in marking and test flow | Choose when future scalability to larger EEPROM or certified automotive grade is required. |
Compared with 24C00/P, 24LC00/P trades automotive temperature capability for broader supply flexibility, while AT24C01A-PU offers higher density and optional AEC-Q100 qualification - making 24C00/P the optimal choice strictly for cost-sensitive, high-temp 128-bit storage where pin count and footprint are constrained.

FAQ
What is the minimum VCC required for reliable operation of the 24C00/P?
The 24C00/P requires a minimum VCC of 4.5 V for guaranteed operation. Its internal voltage detector disables write functionality below 3.8 V, and the device will not respond to I²C commands outside the 4.5–5.5 V range. Unlike the 24AA00 or 24LC00 variants, it is not specified for operation at 1.8 V or 2.5 V.
Does the 24C00/P support multi-master I²C bus configurations?
Yes, the 24C00/P fully complies with the I²C specification as a slave-only device and supports multi-master bus topologies. It responds only to its fixed 7-bit address (1010xxx), generates ACK/NACK as required, and releases SDA after each byte - enabling arbitration and collision detection handled entirely by the master(s).
Can the NC pins on the 24C00/P PDIP package be used for grounding or decoupling?
No. Pins 3, 5, 6, and 7 of the 24C00/P PDIP package are unconnected die pads with no internal bond wires. They must remain electrically floating or be tied to ground only if required by PCB mechanical or thermal design - never used as signal or power paths, as they provide no electrical function.
How many times can the 24C00/P be rewritten before wear-out?
The 24C00/P is rated for more than 1 million erase/write cycles per memory location. This endurance is ensured by characterization (not 100% tested), and data retention exceeds 200 years at +85°C - making it suitable for applications where writes occur infrequently, such as factory programming or rare field updates.
Is the 24C00/P pin-compatible with other 24XX00 family members in PDIP packages?
Yes - all 24XX00 family members (24AA00, 24LC00, 24C00) share identical 8-pin PDIP pinouts: Pin 1 = SCL, Pin 2 = SDA, Pin 4 = VSS, Pin 8 = VCC, and Pins 3/5/6/7 = NC. However, voltage and temperature ratings differ, so direct substitution requires validation of system-level VCC and ambient conditions.
