Product details
Overview
25LC010AT-E/MS from Microchip Technology Inc. is a 1 Kbit SPI Serial EEPROM with 128 × 8-bit organization, 16-byte page write capability, and industrial-temperature operation (−40°C to +85°C). It supports up to 10 MHz clock frequency at 4.5–5.5 V, features hardware write protection via WP pin, and delivers 1 million erase/write cycles with >200-year data retention - used for configuration storage in microcontroller-based embedded systems.
For engineers reviewing the 25LC010AT-E/MS datasheet, 25LC010AT-E/MS pinout, 25LC010AT-E/MS application, or 25LC010AT-E/MS equivalent, key selection criteria include VCC range (2.5–5.5 V), MSOP-8 package compatibility, HOLD functionality for interrupt-safe SPI pauses, and block-level write protection (BP0/BP1 bits) enabling selective array locking.
Technical Context
The 25LC010AT-E/MS implements a standard SPI Mode 0,0/Master-Slave interface with separate SI (data-in) and SO (data-out) lines, requiring CS, SCK, and optional HOLD/WP control. Its internal architecture includes an 8-bit instruction register, page latches, and HV generator for EEPROM programming.
Write operations require explicit WREN instruction followed by CS high-to-low transition to initiate self-timed internal write cycle (≤5 ms); STATUS register (WIP/WEL/BP0/BP1) enables real-time monitoring and nonvolatile protection configuration. HOLD suspends ongoing transfers while preserving internal state, allowing host MCU to service higher-priority interrupts without reinitialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Kbit (128 × 8-bit array), sufficient for small firmware parameters or calibration data storage |
| Interface | SPI-compatible serial bus (Mode 0,0), compatible with PIC® and most MCU SPI peripherals without bit-banging |
| Max Clock Frequency | 10 MHz at VCC ≥ 4.5 V - enables fast read/write bursts in time-critical applications |
| Page Write Size | 16 bytes per page - optimizes write efficiency while preventing cross-page wrap-around corruption |
| Write Endurance | 1,000,000 erase/write cycles - supports long-life field deployments in industrial controllers |
| Data Retention | >200 years at +25°C - ensures persistent storage integrity across product lifecycle |
| Operating Temp | −40°C to +85°C (Industrial grade) - validated for use in automotive ECUs and factory automation hardware |
| Supply Voltage | 2.5 V to 5.5 V - interoperable with both 3.3 V and 5 V logic domains without level shifting |
Pinout & Package
25LC010AT-E/MS is housed in an 8-lead MSOP (Mini Small Outline Package) with 0.15-inch body width and exposed pad option (VSS-connected or floating per design).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS) | Chip Select Input | Active-low enable: pulls device into active mode; rising edge initiates internal write cycle after valid command sequence |
| 2 (SO) | Serial Data Output | Tri-state output: drives data on falling edge of SCK during reads; high-Z when deselected or HOLD asserted |
| 3 (WP) | Write-Protect Pin | Hardware lock: low disables all writes to memory and STATUS register regardless of WEL state |
| 4 (VSS) | Ground | Reference return path for all digital and analog circuitry; exposed pad may be connected here for thermal relief |
| 5 (SI) | Serial Data Input | Latches instructions, addresses, and data on rising edge of SCK; supports MSb-first SPI protocol |
| 6 (SCK) | Serial Clock Input | Synchronizes all data transfers; timing constraints (e.g., TCSS, THD) scale with VCC for robustness across voltage range |
| 7 (HOLD) | Hold Input | Pauses ongoing SPI transfer without resetting state; must be driven low while SCK is low to avoid metastability |
| 8 (VCC) | Supply Voltage | Power input: 2.5–5.5 V operation with 5 µA standby current at 2.5 V - critical for battery-backed systems |
Key Features
| Feature | Design Value |
|---|---|
| Block Write Protection | Selectively locks 0%, 25%, 50%, or 100% of memory array via BP0/BP1 bits - prevents accidental overwrites of critical boot code |
| Self-Timed Write Cycle | Internal 5 ms max. write completion eliminates need for external delay timers or polling overhead in firmware |
| HOLD Functionality | Enables deterministic SPI pause/resume during MCU interrupt handling - avoids communication loss or re-synchronization logic |
| Low-Power Operation | 5 µA standby current at 2.5 V and +85°C - extends battery life in portable instrumentation and sensor nodes |
| ESD Robustness | >4 kV HBM ESD rating on all pins - enhances reliability in manufacturing and field environments with static exposure |
| RoHS Compliance | Pb-free MSOP package with Matte Tin (Sn) finish - meets global environmental regulations without solderability compromise |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 25AA010AT-I/MS | Wider VCC range (1.8–5.5 V); identical pinout, timing, and feature set | Better suited for 1.8 V or mixed-voltage systems where 25LC010AT-E/MS cannot operate below 2.5 V | Select 25AA010AT-I/MS if system uses 1.8 V logic or requires extended low-VCC margin |
| AT25010B-MAHL-T | Same 1 Kbit size, SPI interface, and MSOP-8 package; 20 MHz max clock; 5.5 V absolute max rating | Higher speed and broader voltage tolerance (1.8–5.5 V), but lacks HOLD pin and has different status register layout | Choose AT25010B-MAHL-T only when HOLD functionality is unnecessary and higher throughput justifies firmware adaptation |
Compared with 25LC010AT-E/MS, 25AA010AT-I/MS offers lower-voltage flexibility without trade-offs, while AT25010B-MAHL-T sacrifices HOLD and protection granularity for speed - making 25LC010AT-E/MS optimal for interrupt-sensitive, industrial-temp designs needing robust hardware write control.

FAQ
What is the maximum clock frequency supported by the 25LC010AT-E/MS?
The 25LC010AT-E/MS supports up to 10 MHz clock frequency when VCC is between 4.5 V and 5.5 V. At lower voltages (2.5–4.5 V), the maximum clock drops to 5 MHz. This scaling ensures timing compliance across its full 2.5–5.5 V operating range, and all AC specifications in the DS21832H datasheet are validated per voltage bin.
Does the 25LC010AT-E/MS have built-in write protection features?
Yes, the 25LC010AT-E/MS includes dual-layer write protection: a hardware WP pin that disables all writes when pulled low, and software-configurable Block Protection bits (BP0/BP1) in the STATUS register to lock 0%, 25%, 50%, or 100% of the memory array. Both mechanisms operate independently and are retained across power cycles.
Can the 25LC010AT-E/MS be used in automotive applications?
The 25LC010AT-E/MS is rated for Industrial temperature (−40°C to +85°C), not Automotive (−40°C to +125°C). For automotive use, Microchip specifies the 25LC010A variant with suffix 'E' (e.g., 25LC010AE/MS). The 'T-E/MS' in 25LC010AT-E/MS denotes tape-and-reel packaging and Industrial grade - confirm ambient thermal profile before deployment in under-hood environments.
How does the HOLD pin function on the 25LC010AT-E/MS?
The HOLD pin on the 25LC010AT-E/MS suspends ongoing SPI communication without resetting internal state. When asserted low (while SCK is low), SI/SO/SCK inputs are ignored except CS, allowing the host MCU to service interrupts. Resuming requires bringing HOLD high while SCK remains low - this preserves address pointer and command context for seamless continuation.
What is the page write capability of the 25LC010AT-E/MS?
The 25LC010AT-E/MS supports page write mode with a 16-byte buffer. Up to 16 sequential bytes can be loaded before triggering the internal 5 ms write cycle. Writes crossing physical page boundaries (addresses ending in 0x0F) wrap within the same page - firmware must enforce alignment to prevent unintended overwrites.
