Product details
Overview
24LC16BHT-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 hardware write-protect for half-array (400h–7FFh). It is used in industrial and extended-temperature embedded systems for parameter storage, calibration data retention, and configuration backup.
For engineers reviewing the 24LC16BHT-E/MNY datasheet, 24LC16BHT-E/MNY pinout, 24LC16BHT-E/MNY application, or 24LC16BHT-E/MNY equivalent, key selection considerations include its 2.5V–5.5V VCC range, E-temp (–40°C to +125°C) rating, MNY package (8-lead TSSOP), half-array write-protection via WP pin, and compatibility with standard I²C bus timing at 400 kHz.
Technical Context
The 24LC16BHT-E/MNY 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-bit address pointer, 16-byte page write buffer, and HV generator for EEPROM programming.
It supports byte and page write operations, with automatic self-timed erase/write cycles and acknowledge polling for write completion detection. The device uses block-select addressing (B2–B0 bits) to access one of eight 256-word memory blocks, and enforces write protection only when WP = VCC - disabling writes to addresses 400h–7FFh while allowing 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 firmware parameter partitioning. |
| VCC Range | 2.5V to 5.5V - compatible with 3.3V and 5V logic domains without level shifting. |
| Max Clock Frequency | 400 kHz - supports high-speed I²C communication while maintaining robust noise immunity. |
| Page Write Time | 5 ms maximum - defines minimum interval between successive page writes in configuration update routines. |
| Write Endurance | 1 million erase/write cycles - ensures long-term reliability in field-updatable systems. |
| Data Retention | 200 years at +85°C - guarantees nonvolatile storage integrity over product lifetime in harsh environments. |
| Temperature Range | –40°C to +125°C (Extended grade) - qualified for under-hood automotive and industrial control applications. |
| Write Protection | Hardware-enabled half-array (400h–7FFh) via WP pin - prevents accidental overwrite of critical firmware parameters. |
Pinout & Package
24LC16BHT-E/MNY is packaged in an 8-lead TSSOP (MNY), measuring 4.4 mm × 3.0 mm × 1.2 mm, with gull-wing leads and JEDEC-standard footprint. Pin 1 is marked by a beveled corner or dot.
| 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 write protection (400h–7FFh); logic-low (VSS) disables protection for full-array writes. |
| SCL | Serial clock input | Master-generated clock synchronizing all I²C transactions; requires external pull-up resistor (2 kΩ typical). |
| SDA | Serial data I/O | Bidirectional open-drain bus line; requires external pull-up resistor and supports multi-master arbitration. |
| VCC | Power supply | Primary power rail (2.5V–5.5V); decoupling capacitor (0.1 μF ceramic) required within 5 mm of pin. |
| A0, A1, A2 | Address inputs | No internal connection - may be left floating or tied to VSS/VCC without functional impact. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 0.05 VCC hysteresis on SDA/SCL - rejects sub-50 ns noise spikes and ensures reliable bus operation in electrically noisy environments. |
| Output slope control | Controlled rise/fall times per I²C spec - eliminates ground bounce during fast transitions and reduces EMI emissions. |
| 16-byte page write buffer | Enables burst writes up to 16 bytes per Stop condition - cuts firmware update time by ~85% vs. byte-write mode. |
| Self-timed write cycle | No external timing components needed - internal HV generator and state machine handle erase/write sequencing automatically. |
| ESD protection | >4 kV HBM - meets IEC 61000-4-2 Level 3 requirements for system-level ESD robustness. |
| RoHS & AEC-Q100 | Qualified for automotive Grade 1 (–40°C to +125°C) - suitable for engine control, ADAS, and infotainment modules. |

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/MNY | 1.7V–5.5V VCC range; supports 100 kHz at VCC < 2.5V; identical pinout and memory map. | Better suited for ultra-low-voltage systems (e.g., coin-cell-powered IoT sensors) but lacks AEC-Q100 qualification. | Select 24AA16HT-E/MNY only if sub-2.5V operation is required; otherwise, 24LC16BHT-E/MNY offers superior automotive compliance. |
| AT24C16C-MAHM-T | Same 16 Kbit capacity, 400 kHz, 2.5V–5.5V, and TSSOP-8 package; rated –40°C to +125°C but not AEC-Q100 qualified. | Lower cost alternative with comparable AC specs but no automotive stress testing or failure-in-time (FIT) data published. | Use AT24C16C-MAHM-T for cost-sensitive industrial designs where AEC-Q100 is not mandated; verify WP functionality matches Microchip's half-array scheme. |
Compared with 24AA16HT-E/MNY and AT24C16C-MAHM-T, the 24LC16BHT-E/MNY uniquely combines AEC-Q100 qualification, hardware half-array write protection, and guaranteed 200-year data retention - making it the preferred choice for safety-critical automotive and medical applications requiring certified reliability.

FAQ
What is the maximum clock frequency supported by the 24LC16BHT-E/MNY?
The 24LC16BHT-E/MNY supports a maximum I²C clock frequency of 400 kHz across its full 2.5V–5.5V VCC range and –40°C to +125°C operating temperature. This is confirmed in the Device Selection Table and AC Characteristics section of DS20002118B, where FCLK is specified as 400 kHz for 24LC16BH devices. It does not support 1 MHz operation - that capability is exclusive to the 24FC16H variant.
Does the 24LC16BHT-E/MNY require external pull-up resistors on SDA and SCL lines?
Yes, the 24LC16BHT-E/MNY requires external pull-up resistors on both SDA and SCL lines because it uses open-drain outputs. The datasheet specifies 2 kΩ as typical for 400 kHz operation. Pull-up values must be selected based on bus capacitance and speed requirements - lower resistance improves rise time but increases power consumption during low states.
How does the hardware write-protect feature work on the 24LC16BHT-E/MNY?
When the WP pin of the 24LC16BHT-E/MNY is tied to VCC, write operations to memory addresses 400h–7FFh are inhibited while reads remain fully functional. If WP is tied to VSS, full-array write access is enabled. This half-array protection is implemented entirely in hardware and requires no software configuration or register writes.
What is the meaning of "MNY" in the part number 24LC16BHT-E/MNY?
"MNY" is Microchip's package code for 8-lead TSSOP (Thin Shrink Small Outline Package), measuring 4.4 mm × 3.0 mm × 1.2 mm. It appears in the Device Selection Table and Packaging Information section of DS20002118B and corresponds to JEDEC MO-153AC. The "T" denotes tape-and-reel packaging, and "E" indicates Extended temperature grade (–40°C to +125°C).
Can the 24LC16BHT-E/MNY be used in automotive applications?
Yes, the 24LC16BHT-E/MNY is explicitly AEC-Q100 qualified for automotive Grade 1 (–40°C to +125°C), as stated in the Features section of DS20002118B. Its design includes enhanced ESD protection (>4 kV), extended temperature operation, and reliability validation per automotive stress test standards - making it suitable for body control, infotainment, and ADAS subsystems.
