Product details
Overview
24FC16-E/MS from Microchip Technology Inc. is a 16-Kbit I²C-compatible serial EEPROM organized as eight 256 × 8-bit blocks, supporting 1 MHz clock frequency at 1.7V–5.5V supply, with hardware write-protection, 16-byte page buffer, and extended temperature operation to +125°C. It serves as nonvolatile configuration storage in industrial sensor nodes, automotive body controllers, and power management units requiring low-voltage robustness.
For engineers reviewing the 24FC16-E/MS datasheet, 24FC16-E/MS pinout, 24FC16-E/MS application, or 24FC16-E/MS equivalent, this page delivers verified electrical specs, package mapping to MSOP-8, I²C timing compliance at 1 MHz, endurance (1M cycles), and real-world use context for embedded firmware and calibration data retention.
Technical Context
The 24FC16-E/MS implements a two-wire I²C slave interface with Schmitt-trigger inputs and slope-controlled outputs to suppress ground bounce and noise. Its internal architecture includes an 8-bit address pointer, 16-byte page latch, and HV generator for EEPROM programming - enabling self-timed byte/page writes without external timing control.
It supports standard I²C addressing with fixed 4-bit control code '1010', three block-select bits (B2–B0), and R/W bit - allowing selection of one of eight 256-word memory blocks. Write protection is enforced via dedicated WP pin tied to VCC, disabling all write operations while permitting full read access.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8-bit), organized as eight 256-word blocks - enables modular firmware parameter partitioning. |
| Interface | I²C-compatible two-wire bus with 1 MHz max clock (VCC = 1.7–5.5V) - supports high-speed host communication in compact systems. |
| Supply Voltage | 1.7V to 5.5V - ensures compatibility with modern ultra-low-power microcontrollers and legacy 3.3V/5V systems. |
| Write Cycle Time | ≤5 ms per byte or page - enables fast field-updatable calibration data storage without blocking host CPU for extended periods. |
| Endurance & Retention | 1,000,000 erase/write cycles and >200 years data retention - suitable for long-life industrial equipment with infrequent but critical updates. |
| Temperature Range | -40°C to +125°C (Extended grade) - validated for under-hood automotive, motor drives, and industrial edge controllers. |
| Standby Current | 3 μA max at +125°C - minimizes quiescent power in always-on battery-backed applications. |
Pinout & Package
24FC16-E/MS is supplied in an 8-lead MSOP (Micro Small Outline Package) with 0.65 mm pitch, 3.0 mm × 3.0 mm body, and exposed pad (optional VSS connection). Pin 1 is marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS | Ground reference | Primary return path for all internal circuitry; exposed pad may be connected to VSS for thermal and EMI improvement. |
| SDA | Serial Data I/O | Open-drain bidirectional line requiring external pull-up; carries addresses, commands, and data; supports ACK polling during write cycles. |
| SCL | Serial Clock input | Master-generated clock synchronizing all transfers; Schmitt-trigger input ensures noise immunity on noisy PCBs. |
| WP | Write-Protect control | Logic-high disables all write operations (byte/page); logic-low enables full read/write - provides hardware-level security against accidental overwrites. |
| VCC | Power supply | Single 1.7–5.5V rail powers EEPROM array, logic, and I/O; no separate VPP required due to integrated charge pump. |
Key Features
| Feature | Design Value |
|---|---|
| 1 MHz I²C operation down to 1.7V | Enables faster configuration loading than 400 kHz EEPROMs (e.g., 24AA16), reducing boot time in resource-constrained hosts. |
| 16-byte page write buffer | Allows burst writing of up to 16 bytes per Stop condition - cuts write latency by ~94% vs. single-byte writes for typical calibration tables. |
| Schmitt-trigger inputs + output slope control | Eliminates false Start/Stop detection and ground bounce in electrically noisy environments like motor control boards. |
| Hardware write-protection via WP pin | Prevents firmware corruption during brown-out, reset, or software faults - no firmware dependency required for memory safety. |
| ESD protection >4 kV HBM | Withstands handling and board-level ESD events without latch-up or parametric shift - reduces field failure risk in unshielded assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA16-I/MS | Max I²C clock = 400 kHz (100 kHz below 2.5V); same 1.7–5.5V range and MSOP-8 package. | Limited to lower-speed hosts (e.g., legacy PIC MCUs); not rated for +125°C operation. | Select when cost sensitivity outweighs speed/temperature needs and host clock ≤400 kHz. |
| AT24C16C-MAHM-T | 1 MHz I²C, 1.7–5.5V, -40°C to +125°C, same 16Kbit density and 8-lead TSSOP - but no WP pin; write protection via software lock bits only. | Lacks hardware write-protection; requires firmware coordination to prevent corruption during resets. | Choose if board layout lacks WP routing space and software-controlled protection suffices for the safety architecture. |
Compared with 24AA16-I/MS, the 24FC16-E/MS delivers 2.5× faster I²C throughput and extended temperature capability; versus AT24C16C-MAHM-T, it adds hardware-level WP for fail-safe memory integrity - critical in safety-critical or unattended deployments.

FAQ
What is the maximum I²C clock frequency supported by the 24FC16-E/MS?
The 24FC16-E/MS supports up to 1 MHz I²C clock frequency across its full 1.7V–5.5V supply range, unlike the 24AA16 (max 400 kHz) or 24LC16B (max 400 kHz, min 2.5V). This is confirmed in Table "Device Selection" and AC Characteristics (Param No. 1, FCLK) of DS20001703M, where 24FC16 is explicitly listed for 1000 kHz operation at 1.7V–5.5V.
Does the 24FC16-E/MS require an external VPP voltage for write operations?
No, the 24FC16-E/MS does not require an external VPP voltage. It integrates an on-chip high-voltage charge pump powered solely from VCC (1.7–5.5V), enabling full byte and page write functionality using only the main supply rail - confirmed in the Block Diagram (DS20001703M, page 2) and Functional Description section.
How is hardware write-protection implemented on the 24FC16-E/MS?
Hardware write-protection on the 24FC16-E/MS is controlled by the WP pin: when tied to VCC, all write operations (byte and page) are inhibited while read access remains fully functional; when tied to VSS, normal read/write operation is enabled. This behavior is documented in Section 2.4 "Write-Protect (WP)" and Figure 6-1 of DS20001703M.
What is the page size and maximum page write length for the 24FC16-E/MS?
The 24FC16-E/MS has a 16-byte page buffer and supports page writes of up to 16 bytes within a single physical page boundary. Attempting to write across a page boundary causes wraparound within the current page - specified in Section 6.2 "Page Write" and Figure 6-2 of DS20001703M.
Is the 24FC16-E/MS qualified for automotive applications?
Yes, the 24FC16-E/MS is AEC-Q100 qualified and rated for Extended temperature range (-40°C to +125°C), making it suitable for automotive body electronics, infotainment subsystems, and powertrain-related auxiliary modules - as stated in the "Features" list and "Device Selection Table" of DS20001703M.
