Product details
Overview
24LC16BHT-E/SN 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 hardware half-array write-protection (400h–7FFh). It supports industrial and extended temperature ranges (–40°C to +125°C) and is used in embedded system configuration storage, sensor calibration data retention, and firmware parameter backup.
For engineers reviewing the 24LC16BHT-E/SN datasheet, 24LC16BHT-E/SN pinout, 24LC16BHT-E/SN application, or 24LC16BHT-E/SN equivalent, key selection criteria include VCC range compatibility (2.5–5.5V), I²C timing compliance at 400 kHz, SOIC-8 package footprint, WP-enabled memory protection scheme, and endurance specification of 1 million erase/write cycles.
Technical Context
The 24LC16BHT-E/SN implements a two-wire I²C slave interface with Schmitt-trigger inputs and slope-controlled outputs to suppress noise and eliminate ground bounce. Its internal architecture includes an 8-byte address pointer, 16-byte page write buffer, and HV generator for EEPROM programming.
It uses block-select addressing (3-bit B2:B0) within the I²C control byte to access one of eight 256-word memory blocks, enabling deterministic memory mapping without external address lines. Write protection is implemented via the WP pin: tied to VCC, it disables writes to addresses 400h–7FFh while permitting full read access.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8), organized as eight 256-word blocks - enables modular data partitioning and efficient block-level access. |
| VCC Range | 2.5V to 5.5V - compatible with 3.3V and 5V logic systems; excludes 1.7V operation supported by AA/FC variants. |
| Max Clock Frequency | 400 kHz - defines maximum I²C bus speed; requires appropriate pull-up resistor sizing (e.g., ~2 kΩ for 400 kHz). |
| Page Write Time | 5 ms maximum - determines minimum delay between successive page writes; impacts firmware update latency. |
| Endurance | 1,000,000 erase/write cycles - ensures long-term reliability in field-updatable applications like calibration storage. |
| Data Retention | 200 years - guarantees nonvolatile data integrity over product lifetime without refresh. |
| Write Protection | Hardware half-array (400h–7FFh) via WP pin - allows secure storage of factory-set parameters while permitting user data updates in lower half. |
Pinout & Package
24LC16BHT-E/SN is packaged in an 8-lead narrow SOIC (SN) with 1.27 mm pitch, 3.90 mm body width, and JEDEC MS-012AC compliant footprint. The package supports surface-mount assembly and standard reflow profiles.
| 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 | Write-protect input | Logic-high (VCC) enables half-array protection (400h–7FFh); logic-low (VSS) enables full-memory write access. |
| SCL | Serial clock input | Asynchronous I²C clock signal; open-drain requires external pull-up; timing defines data sampling window. |
| SDA | Serial data I/O | Bidirectional open-drain bus line; requires external pull-up; carries address, data, and ACK/NACK signals. |
| VCC | Power supply | Primary supply rail (2.5–5.5V); decoupling capacitor (0.1 μF ceramic) required near pin for noise immunity. |
| A0, A1, A2 | No-connect (NC) | Internally unconnected; may be left floating or tied to VSS/VCC with no functional impact. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Input hysteresis ≥0.05×VCC - rejects bus noise up to 50 ns spikes and prevents false edge detection on SCL/SDA. |
| Output slope control | Controlled rise/fall times - eliminates ground bounce during switching, critical for mixed-signal PCB layouts. |
| Self-timed write cycle | No external timing components needed - simplifies system design and removes dependency on host MCU timing margins. |
| 16-byte page write buffer | Reduces I²C transaction overhead - enables burst writes of up to 16 bytes per Stop condition, improving throughput vs. byte-write mode. |
| ESD protection | >4 kV HBM - meets industrial handling requirements and reduces need for external ESD protection on board. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA16HT-E/SN | Wider VCC range (1.7–5.5V); same 400 kHz max clock; identical SOIC-8 package and pinout. | Supports 1.7V–2.5V systems where 24LC16BHT-E/SN cannot operate; suitable for ultra-low-voltage battery-powered devices. | Select when system VCC may dip below 2.5V; verify timing margins at sub-2.5V operation per DS20002118B Table 1-2. |
| 24LC16B-I/SN | Same electrical specs but rated only for industrial temperature (–40°C to +85°C), not extended (–40°C to +125°C). | Lacks extended temperature qualification; unsuitable for under-hood automotive or high-ambient industrial environments. | Choose only for cost-sensitive applications within 85°C ambient; confirm thermal derating does not impact reliability. |
Compared with 24LC16BHT-E/SN, the 24AA16HT-E/SN extends voltage flexibility at no timing or package trade-off, while the 24LC16B-I/SN reduces temperature capability - making the T-E/SN variant optimal for extended-range deployments requiring guaranteed operation up to +125°C.

FAQ
What is the maximum I²C clock frequency supported by the 24LC16BHT-E/SN?
The 24LC16BHT-E/SN supports a maximum I²C clock frequency of 400 kHz when VCC is between 2.5V and 5.5V. This is confirmed in the Device Selection Table and AC Characteristics section of DS20002118B. Operation above 400 kHz is not specified or guaranteed for this variant - unlike the 24FC16H, which supports 1 MHz. The 24LC16BHT-E/SN must be configured accordingly in host firmware to avoid communication failures.
How does the WP pin function on the 24LC16BHT-E/SN?
On the 24LC16BHT-E/SN, the WP pin enables hardware write protection: when tied to VCC, writes to memory addresses 400h–7FFh are inhibited while reads remain fully functional; when tied to VSS, full memory write access is enabled. This behavior is explicitly defined in Section 2.4 and Figure 6-3 of DS20002118B. The pin has no effect on the upper or lower address bits - only on write enable for the protected half-array.
Is the 24LC16BHT-E/SN AEC-Q100 qualified?
Yes, the 24LC16BHT-E/SN is AEC-Q100 qualified, as stated in the Features section of DS20002118B. This qualification applies to the extended temperature grade (–40°C to +125°C), confirming suitability for automotive applications such as body control modules and infotainment subsystems where reliability under thermal stress is mandatory.
What package type does the 24LC16BHT-E/SN use?
The 24LC16BHT-E/SN uses an 8-lead narrow SOIC package (JEDEC MS-012AC), designated by the "SN" suffix. Package dimensions are documented in Microchip Drawing C04-057-SN Rev D, with 3.90 mm body width, 1.27 mm lead pitch, and standard gull-wing lead form. This package is compatible with automated SMT assembly and IPC-7351B land patterns.
Does the 24LC16BHT-E/SN support 1.8V operation?
No, the 24LC16BHT-E/SN does not support 1.8V operation. Its specified VCC range is 2.5V to 5.5V, as clearly defined in the Device Selection Table and Electrical Characteristics sections of DS20002118B. For 1.7V–1.8V systems, the 24AA16HT-E/SN variant is the appropriate alternative, sharing identical pinout and functionality except for the lower voltage threshold.
