Product details
Overview
24LC08BT-E/SN16KVAO from Microchip Technology Inc. is an 8-Kbit I²C-compatible serial EEPROM organized as four 256 × 8-bit memory blocks with hardware write-protection, 16-byte page buffer, and operation from 2.5V to 5.5V. It supports 400 kHz clock frequency, delivers ≤1 mA active current and ≤5 µA extended-temperature standby current, and is rated for -40°C to +125°C. It is used in industrial sensor calibration storage and embedded system configuration retention.
For engineers reviewing the 24LC08BT-E/SN16KVAO datasheet, 24LC08BT-E/SN16KVAO pinout, 24LC08BT-E/SN16KVAO application, or 24LC08BT-E/SN16KVAO equivalent, key selection criteria include VCC range (2.5–5.5 V), extended-temp standby current (≤5 µA), 400 kHz I²C speed, 16-byte page write capability, and hardware WP pin functionality.
Technical Context
The 24LC08BT-E/SN16KVAO implements a two-wire I²C interface with Schmitt-trigger inputs and slope-controlled outputs to suppress noise and eliminate ground bounce. Its internal architecture includes a 16-byte page latch, HV generator for EEPROM programming, and address pointer logic supporting current-address, random, and sequential read modes.
It uses a fixed 4-bit device identifier (1010) with 2-bit block select (B1/B0) enabling access to four independent 256-word memory blocks. Write protection is controlled solely by the WP pin state-tied to VCC for full-array lockout, VSS for normal operation-and is not supported in CSP packages (not applicable here).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 × 8), organized as four 256-word blocks for isolated firmware parameter storage |
| VCC Range | 2.5 V to 5.5 V - compatible with 3.3 V and 5 V systems without level-shifting |
| I²C Clock Speed | Up to 400 kHz - enables fast configuration writes while maintaining robustness on noisy industrial buses |
| Page Write Buffer | 16 bytes - reduces write cycles by 16× vs. byte-write for contiguous data updates |
| Write Cycle Time | Max 5 ms per byte or page - defines minimum inter-write delay for reliable EEPROM endurance |
| Endurance & Retention | 1 million erase/write cycles; >200 years data retention - suitable for long-life industrial deployments |
| Temp Range | -40°C to +125°C (Extended grade) - qualified for under-hood automotive and high-temp industrial environments |
Pinout & Package
24LC08BT-E/SN16KVAO is supplied in an 8-lead SOIC (SN) package with 3.90 mm body width, JEDEC MS-012AC compliant, and marked "24LC08BT-E/SN" with date code and traceability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS | Ground reference | Return path for all internal circuitry; must be low-impedance connection to system GND plane |
| WP | Hardware write-protect input | Logic-high (VCC) disables all write operations; logic-low (VSS) enables full read/write access |
| SCL | Serial clock input | Asynchronous master-generated clock synchronizing all I²C transfers; requires external pull-up |
| SDA | Serial data bidirectional I/O | Open-drain bus line for address/data transfer; requires external 2–10 kΩ pull-up depending on speed |
| VCC | Power supply | Primary power rail; bypass capacitor (0.1 µF) required within 10 mm of pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 50 mV hysteresis on SDA/SCL - rejects sub-50 ns noise spikes common in motor-driven industrial environments |
| Output slope control | Controlled rise/fall times - prevents ground bounce during fast transitions on shared PCB return paths |
| Self-timed write cycle | No external timing components needed - simplifies firmware design and eliminates host polling overhead |
| ESD protection | >4 kV HBM - withstands handling and board-level ESD events without external protection diodes |
| RoHS & AEC-Q100 | Qualified for automotive Grade 1 (−40°C to +125°C) - meets reliability requirements for safety-critical ECUs |
Applications
| Industrial Sensor Calibration | Automotive ECU Configuration |
|---|---|
Use Scenario: Storing factory-calibrated offset/gain coefficients for temperature, pressure, and current sensors in programmable logic controllers.

IC Role / Device Role / Timing Role: Secure, WP-enabled storage for critical runtime parameters; accessed during boot sequence and runtime reconfiguration. Use Value: Prevents accidental overwrites via hardware WP pin tied to MCU GPIO, ensuring parameter integrity during diagnostics or reflashing. |
| Medical Device Settings | Smart Meter Firmware Patch Storage |
Use Scenario: Retaining user-adjusted therapy settings (e.g., infusion rate, alarm thresholds) in portable infusion pumps. IC Role / Device Role / Timing Role: Low-power EEPROM interfaced to ARM Cortex-M0+ MCU; accessed infrequently but requiring guaranteed retention over 10+ years.

Use Value: Enables secure, atomic firmware updates with rollback capability using 16-byte page writes to minimize flash wear. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA08T-I/SN | Wider VCC range (1.7–5.5 V); lower 100 kHz max speed below 2.5 V; rated only to +85°C | Not suitable for extended-temp automotive or industrial edge nodes above 85°C | Select when operating below 2.5 V or requiring broader voltage flexibility at reduced speed |
| 24FC08T-E/SN | 1 MHz I²C support; 1.7–5.5 V operation; same 16-byte page buffer and WP pin | Higher-speed requirement for real-time logging or burst configuration loads | Choose when system clock budget allows 1 MHz I²C and extended-temp operation is needed with faster throughput |
Compared with 24AA08T-I/SN, the 24LC08BT-E/SN16KVAO trades voltage flexibility for guaranteed 400 kHz performance across its full 2.5–5.5 V range and extended-temperature qualification. Against 24FC08T-E/SN, it sacrifices 1 MHz speed for tighter process control and lower cost in applications where 400 kHz suffices.

FAQ
What is the maximum I²C clock frequency supported by the 24LC08BT-E/SN16KVAO?
The 24LC08BT-E/SN16KVAO supports up to 400 kHz I²C clock frequency across its full 2.5 V to 5.5 V supply range and -40°C to +125°C operating temperature. This is confirmed in the Device Selection Table and AC Characteristics section of DS20001710M, where 400 kHz is specified for 24LC08B devices at VCC ≥ 2.5 V. The 24LC08BT-E/SN16KVAO does not support 1 MHz operation - that capability is exclusive to the 24FC08 variant.
Does the 24LC08BT-E/SN16KVAO support hardware write protection, and how is it implemented?
Yes, the 24LC08BT-E/SN16KVAO implements hardware write protection via the WP pin. When WP is tied to VCC, the entire 8-Kbit memory array (addresses 000h–3FFh) is write-inhibited; read operations remain fully functional. When WP is tied to VSS, normal read/write access is enabled. This behavior is documented in Section 2.4 and Figure 6-3 of DS20001710M and applies to the SOIC (SN) package used in 24LC08BT-E/SN16KVAO.
What is the page write capacity of the 24LC08BT-E/SN16KVAO, and why does it matter?
The 24LC08BT-E/SN16KVAO features a 16-byte page write buffer, allowing up to 16 contiguous bytes to be written in a single I²C transaction. This reduces total write time by up to 16× compared to individual byte writes and minimizes bus occupancy - critical in multi-master systems. The page boundary is aligned to 16-byte offsets (00h, 10h, 20h, etc.), and crossing boundaries causes wraparound, as specified in Section 6.2 of DS20001710M.
Is the 24LC08BT-E/SN16KVAO qualified for automotive applications?
Yes, the 24LC08BT-E/SN16KVAO carries AEC-Q100 qualification for Grade 1 (−40°C to +125°C), as explicitly stated in the Features section of DS20001710M. Its extended temperature rating, 4 kV HBM ESD rating, and robust I²C interface with noise suppression make it suitable for engine control modules, body control units, and ADAS subsystems where reliability under thermal stress is mandatory.
What are the valid supply voltage and temperature specifications for the 24LC08BT-E/SN16KVAO?
The 24LC08BT-E/SN16KVAO operates from 2.5 V to 5.5 V and is rated for −40°C to +125°C (Extended temperature grade). These values are defined in the Device Selection Table and Electrical Characteristics sections of DS20001710M. Operation below 2.5 V is not supported - unlike the 24AA08 (1.7 V min) or 24FC08 (1.7 V min), the 24LC08B family requires ≥2.5 V for guaranteed functionality.
