Product details
Overview
24LC16BT-E/MNY from Microchip Technology Inc. is a 16-Kbit I²C-compatible serial EEPROM organized as eight 256 × 8-bit blocks, operating from 2.5V to 5.5V with 400 kHz max clock frequency, 5 ms max page write time, and industrial/extended temperature support (–40°C to +125°C). It serves as nonvolatile configuration storage in microcontroller-based systems requiring low-power, noise-immune bus interfacing.
For engineers reviewing the 24LC16BT-E/MNY datasheet, 24LC16BT-E/MNY pinout, 24LC16BT-E/MNY application, or 24LC16BT-E/MNY equivalent, this page delivers verified electrical specs, package mapping to 8-lead SOIC (MNY), I²C timing constraints, hardware write-protection behavior, and real-world use context for embedded firmware, sensor calibration, and power-management state retention.
Technical Context
The 24LC16BT-E/MNY implements a two-wire I²C slave interface with Schmitt-trigger inputs and slope-controlled outputs to suppress ground bounce and bus noise. Its internal architecture includes an 8-bit address pointer, 16-byte page write buffer, and HV generator for EEPROM cell programming.
It supports three read modes-current address, random, and sequential-and uses acknowledge polling to detect write cycle completion. The WP pin provides hardware-level array-wide write protection when tied to VCC, while A0–A2 pins are unconnected and may be left floating or tied to VSS/VCC without effect.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8-bit), organized into eight 256-word blocks for segmented addressing |
| VCC Range | 2.5V to 5.5V - ensures compatibility with 3.3V and 5V logic domains without level shifting |
| Max Clock Frequency | 400 kHz at VCC ≥ 2.5V - enables fast configuration loading in real-time systems |
| Page Write Buffer | 16 bytes - reduces I²C transaction count for bulk writes, improving bus efficiency |
| Write Cycle Time | 5 ms maximum - defines worst-case latency before next command can be issued |
| Data Retention | 200 years - guarantees long-term integrity of stored calibration or security keys |
| Endurance | 1 million erase/write cycles - supports frequent field updates in telemetry or logging applications |
Pinout & Package
24LC16BT-E/MNY is packaged in an 8-lead SOIC (narrow, 3.90 mm body) with JEDEC MS-012AC footprint and MNY suffix per Microchip's packaging nomenclature. Pin 1 is marked with a notch or dot; exposed pad is not present in SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS | Ground reference | Return path for all internal circuitry; must be connected to system GND plane for stable operation |
| WP | Hardware write-protect input | Logic-high disables all write operations (000h–7FFh); no effect on reads; enables fail-safe configuration lock |
| SCL | Serial clock input | Master-generated clock synchronizing all I²C transfers; Schmitt-triggered for noise immunity |
| SDA | Bidirectional data line | Open-drain I/O requiring external pull-up; carries addresses, commands, and data; supports multi-master arbitration |
| VCC | Power supply | Primary supply rail (2.5–5.5V); decoupling capacitor (0.1 μF) required within 10 mm of pin |
| A0, A1, A2 | No-connect terminals | Internally unconnected; may be left floating or tied to VSS/VCC with no functional impact |
Key Features
| Feature | Design Value |
|---|---|
| I²C bus compatibility | Fully compliant with Philips I²C specification, supporting standard-mode (100 kHz) and fast-mode (400 kHz) timing |
| Schmitt-trigger inputs | Input hysteresis ≥ 0.05×VCC eliminates false triggering from EMI or slow-rising signals on SCL/SDA |
| Output slope control | Controlled rise/fall times prevent ground bounce during high-speed switching, critical for mixed-signal PCBs |
| Hardware write protection | Single-pin (WP) global lock prevents accidental overwrites during power-up/down or firmware faults |
| Extended temperature range | Rated for –40°C to +125°C operation, validated for automotive under-hood and industrial motor-control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA16T-I/MNY | Lower VCC min (1.7V), same 400 kHz speed, identical SOIC-8 package and pinout | Supports single-cell Li-ion (2.7V) and coin-cell (3V) systems where 24LC16BT-E/MNY cannot operate below 2.5V | Select when system supply drops below 2.5V during brownout or battery depletion scenarios |
| 24FC16T-I/MNY | 1 MHz max clock, 1.7–5.5V VCC, same memory size and SOIC-8 package | Enables faster configuration loading in high-throughput test equipment or FPGA bitstream storage | Choose when bus bandwidth exceeds 400 kHz requirement and voltage margin allows 1.7V operation |
Compared with 24AA16T-I/MNY and 24FC16T-I/MNY, the 24LC16BT-E/MNY trades lower-voltage operation and higher speed for extended temperature capability (–40°C to +125°C), making it optimal for under-hood automotive and industrial motor-drive applications where thermal robustness outweighs voltage flexibility or raw throughput.

FAQ
What is the maximum clock frequency supported by the 24LC16BT-E/MNY?
The 24LC16BT-E/MNY supports a maximum I²C clock frequency of 400 kHz when VCC is 2.5V or higher. At voltages below 2.5V, operation is not specified per its datasheet - unlike the 24AA16 or 24FC16 variants. This 400 kHz limit ensures timing compliance across the full –40°C to +125°C temperature range and enables deterministic bus arbitration in multi-device systems. The 24LC16BT-E/MNY does not support 1 MHz operation.
How does the WP pin function on the 24LC16BT-E/MNY?
On the 24LC16BT-E/MNY, the WP (Write-Protect) pin is a dedicated hardware enable/disable input. When tied to VCC, it inhibits all write operations (byte and page) to the entire 16-Kbit memory array (addresses 000h–7FFh), while read operations remain fully functional. When tied to VSS (or left floating, though not recommended), normal read/write access is enabled. This feature provides deterministic, zero-software-overhead protection against firmware bugs or power glitches corrupting critical configuration data.
Is the 24LC16BT-E/MNY AEC-Q100 qualified?
Yes, the 24LC16BT-E/MNY is AEC-Q100 qualified for automotive applications. Per Microchip's DS20001703M datasheet, the 24LC16B variant - including the -E temperature grade denoted by the "E" in 24LC16BT-E/MNY - is explicitly listed as AEC-Q100 qualified. This qualification covers stress testing for temperature cycling, humidity, ESD, and mechanical shock, confirming suitability for body electronics, infotainment, and powertrain subsystems where reliability under harsh conditions is mandatory.
What package type does the "MNY" suffix indicate for the 24LC16BT-E/MNY?
The "MNY" suffix in 24LC16BT-E/MNY denotes the 8-lead plastic small outline (SOIC) package with narrow body (3.90 mm width), per Microchip's standardized packaging nomenclature. This corresponds to JEDEC MS-012AC and is distinct from MSOP (MS), TSSOP (ST), or DFN (MUY) variants. The MNY package has a 1.27 mm pitch, 5.0 mm length, and 3.9 mm width, and is compatible with standard SOIC-8 footprints and reflow profiles used in high-volume PCB assembly.
Can the A0, A1, and A2 pins on the 24LC16BT-E/MNY be used to configure device addressing?
No - the A0, A1, and A2 pins on the 24LC16BT-E/MNY are not internally connected and serve no addressing function. As confirmed in the datasheet's Pin Function Table (page 7), these pins are "Not Connected" and may be left floating or tied to VSS or VCC without affecting operation. Device addressing is fixed: the 24LC16BT-E/MNY responds only to the 7-bit slave address 0b1010xxx, where the three LSBs (xxx) are ignored. This eliminates address collision risk but also prevents multiple 24LC16BT-E/MNY devices on the same I²C bus.
