Product details
Overview
25LC080DT-I/MNY from Microchip Technology is an 8 Kbit SPI Serial EEPROM with 1024 × 8-bit organization, 32-byte page size, and industrial temperature range (–40°C to +85°C). It operates from 2.5V to 5.5V, supports up to 10 MHz clock frequency, and features hardware write protection via WP pin and STATUS register control. It is used for nonvolatile parameter storage in microcontroller-based embedded systems requiring reliable, low-power data retention.
For engineers reviewing the 25LC080DT-I/MNY datasheet, 25LC080DT-I/MNY pinout, 25LC080DT-I/MNY application, or 25LC080DT-I/MNY equivalent, key selection criteria include SPI interface compatibility, page-write timing (≤5 ms), block protection granularity (1/4, 1/2, or full array), and TDFN-8 package suitability for space-constrained PCB layouts.
Technical Context
The 25LC080DT-I/MNY implements a standard SPI Mode 0,0 (CPOL = 0, CPHA = 0) interface with separate SI and SO lines, CS-controlled selection, and HOLD pin support for interrupt-safe transaction suspension. Its internal architecture includes a 32-byte page latch, status register with WIP/WEL/BP0/BP1 bits, and high-voltage generator for EEPROM cell programming.
It uses CMOS process technology enabling 5 µA standby current at 5.5V and 5 mA active read/write current at 10 MHz, with >1 million erase/write cycles and >200 years data retention. The device powers on with write enable latch reset and SO in high-impedance state, ensuring safe default behavior during power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbit (1024 × 8-bit), providing sufficient space for firmware configuration, calibration data, or event logs in resource-limited systems. |
| Interface | SPI-compatible serial bus (Mode 0,0), requiring only CS, SCK, SI, SO, WP, and HOLD - no parallel bus overhead or address decoding logic. |
| Page Size | 32 bytes, enabling efficient burst writes within a single physical page boundary without wraparound corruption if software enforces alignment. |
| Write Cycle Time | ≤5 ms max internal self-timed erase/write, eliminating need for external polling delay beyond WIP bit checking. |
| VCC Range | 2.5V to 5.5V, supporting direct integration with 3.3V and 5V microcontroller I/O domains without level-shifting. |
| Temperature Range | Industrial grade (–40°C to +85°C), qualified for use in industrial controls, metering, and automotive body electronics subsystems. |
| Endurance & Retention | >1 million erase/write cycles and >200 years data retention at 25°C, ensuring long-term reliability in infrequently updated storage applications. |
Pinout & Package
25LC080DT-I/MNY is housed in an 8-lead 2×3 mm TDFN (Thin Dual Flat No-lead) package with wettable flanks, optimized for automated optical inspection (AOI) and high-density PCB layouts. Pin 1 is marked by a dot or beveled corner per Microchip drawing C04-097B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS) | Chip Select Input | Active-low enable signal; must be held low for entire SPI transaction; rising edge initiates internal write cycle after valid write sequence. |
| 2 (SO) | Serial Data Output | Tri-state open-drain output; data shifted out on falling edge of SCK; enters high-Z when CS is high or HOLD is asserted. |
| 3 (WP) | Write-Protect Input | Hardware lock for STATUS register writes when WPEN bit is set; low = protection enabled; does not affect memory array writes unless BP bits are configured. |
| 4 (VSS) | Ground Reference | Primary return path for all internal circuitry and I/O; requires low-impedance connection to system ground plane. |
| 5 (SI) | Serial Data Input | Data-in line latched on rising edge of SCK; accepts instruction opcodes (e.g., 0x02 for WRITE), addresses, and payload bytes MSB-first. |
| 6 (SCK) | Serial Clock Input | Synchronous timing reference; maximum 10 MHz at VCC ≥ 4.5V; rise/fall times ≤ 2 µs required for reliable sampling. |
| 7 (HOLD) | Transaction Pause Control | Active-low suspend signal; must be asserted while SCK is low to avoid metastability; halts communication without resetting internal state. |
| 8 (VCC) | Supply Voltage | Core power input (2.5–5.5V); internal voltage regulation enables stable operation across wide input range; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Block Write Protection | Selectable protection of none, upper 1/4 (0300h–03FFh), upper 1/2 (0200h–03FFh), or full array (0000h–03FFh) via BP0/BP1 bits - prevents accidental overwrites in critical sectors. |
| Hardware Write Protection | WP pin + WPEN bit combination enables physical lockout of STATUS register writes - allows field-programmable protection without firmware dependency. |
| Hold Function | HOLD pin suspends ongoing SPI transfers mid-sequence, letting host MCU service higher-priority interrupts without reinitializing the transaction - reduces software overhead and latency. |
| Low-Power Operation | 5 µA standby current at 5.5V and 85°C ensures minimal battery drain in always-on or energy-harvesting applications where EEPROM remains powered between accesses. |
| Pb-Free & RoHS Compliance | Meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) - suitable for lead-free reflow assembly without special handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 25LC080D-I/SN | Same 8 Kbit capacity and 32-byte page size, but in SOIC-8 package (5.3 mm × 4.4 mm vs. TDFN's 2.0 mm × 3.0 mm). | Larger footprint suits through-hole or legacy reflow processes; lacks wettable flanks for AOI - less ideal for ultra-compact or automated-optical-inspection-driven production. | Select when board layout accommodates SOIC or when hand-soldering/repairability is prioritized over miniaturization. |
| AT25080B-MAHL-T | 8 Kbit SPI EEPROM with 16-byte page size, 2.5–5.5V supply, and industrial temp range; manufactured by Microchip (acquired Atmel). | Smaller page size increases write overhead for multi-byte updates; identical pinout but different STATUS register bit mapping affects protection configuration code portability. | Choose when existing firmware uses Atmel-specific RDSR/WRSR sequences or when sourcing diversification across Microchip's merged portfolio is required. |
Compared with 25LC080D-I/SN, the 25LC080DT-I/MNY saves >70% board area and enables AOI-ready assembly; versus AT25080B-MAHL-T, it offers larger page writes and native Microchip instruction compatibility - reducing firmware adaptation effort in new designs.

FAQ
What is the maximum clock frequency supported by the 25LC080DT-I/MNY?
The 25LC080DT-I/MNY supports up to 10 MHz SPI clock frequency when VCC is 4.5V to 5.5V. At 2.5V ≤ VCC < 4.5V, the maximum clock drops to 5 MHz, and at 1.8V ≤ VCC < 2.5V, it is rated for 3 MHz - though the 25LC080DT-I/MNY's minimum VCC is 2.5V, so the 3 MHz rating does not apply. This ensures timing compliance across its specified supply range.
Does the 25LC080DT-I/MNY require external pull-up resistors on its SO or SI lines?
No, the 25LC080DT-I/MNY does not require external pull-ups on SO or SI. The SO pin is internally driven and tri-stated when inactive; SI is a CMOS input with negligible leakage. Pull-ups are only needed if the host MCU lacks internal weak pull-ups and the bus is shared with other open-drain devices - not a requirement of the 25LC080DT-I/MNY itself.
How does the HOLD function behave during an active write cycle in the 25LC080DT-I/MNY?
The HOLD pin has no effect during an internal write cycle (TWC phase) of the 25LC080DT-I/MNY. Once CS rises to initiate the 5 ms self-timed write, the device ignores HOLD transitions until the cycle completes and SO returns to high-impedance. HOLD only pauses read/write command sequences - not the internal EEPROM programming operation.
Can the 25LC080DT-I/MNY be used with a 1.8V microcontroller?
No, the 25LC080DT-I/MNY is not rated for 1.8V operation. Its absolute minimum VCC is 2.5V, as confirmed in the Device Selection Table and Electrical Characteristics section. For 1.8V systems, Microchip's 25AA080D-I/MNY (1.8–5.5V) is the compatible alternative with identical pinout and functionality.
What package type does the 'MNY' suffix indicate for the 25LC080DT-I/MNY?
The 'MNY' suffix in 25LC080DT-I/MNY denotes Microchip's 8-lead 2×3 mm TDFN (Thin Dual Flat No-lead) package with wettable flanks. This is verified in the Packaging Information section (DS22151B-page 14–15), where 'MN' maps to TDFN and 'Y' indicates Pb-free/RoHS-compliant finish - distinct from SOIC (SN), TSSOP (ST), or PDIP (P) variants.
