Product details
Overview
25LC160D-H/SN from Microchip Technology is a 16-Kbit (2,048 × 8) SPI serial EEPROM with extended temperature operation (–40°C to +150°C), 5 MHz max clock speed, 32-byte page size, and hardware write protection via WP pin and STATUS register control. It delivers high reliability for automotive and industrial systems requiring nonvolatile data storage under thermal stress.
For engineers reviewing the 25LC160D-H/SN datasheet, 25LC160D-H/SN pinout, 25LC160D-H/SN application, or 25LC160D-H/SN equivalent, key selection factors include its AEC-Q100 qualification, 1,000,000 write/erase endurance, 200-year data retention, and support for byte/page writes with self-timed 6 ms internal write cycles.
Technical Context
The 25LC160D-H/SN implements a standard SPI Mode 0,0/Master-Slave interface with separate SI (data in) and SO (data out) lines, CS-controlled selection, and HOLD pin for transaction suspension without reset. Its internal architecture includes an 8-bit instruction register, page latches, HV generator, and EEPROM array with X/Y decoding.
It supports four block protection configurations (none, 1/4, 1/2, or full array) via BP0/BP1 bits in the nonvolatile STATUS register, and enables hardware write protection only when WPEN = 1 and WP = low - allowing flexible, field-programmable memory security without firmware dependency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Kbit (2,048 × 8 organization) - fits compact firmware logging or calibration storage in space-constrained modules |
| Max Clock Speed | 5 MHz at VCC ≥ 4.5V - enables fast configuration reads in real-time control loops |
| Page Size | 32 bytes - allows efficient bulk parameter updates while avoiding cross-page wrap errors |
| Write Cycle Time | 6 ms maximum - defines minimum interval between write commands; impacts system responsiveness during save operations |
| Endurance | >1,000,000 erase/write cycles - supports daily recalibration over 27+ years of operation |
| Data Retention | >200 years at +150°C - ensures long-term integrity in under-hood automotive environments |
| Temp Range | –40°C to +150°C (Extended H grade) - qualified per AEC-Q100 Grade 0 for engine control and transmission modules |
Pinout & Package
8-Lead SOIC (SN package), 3.90 mm body width, RoHS-compliant matte tin finish. Pin 1 marked with notch or dot; top-view orientation follows JEDEC MS-012 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS (Pin 1) | Chip Select Input | Active-low enable; forces standby mode when high; rising edge initiates internal write cycle after valid command |
| SO (Pin 2) | Serial Data Output | Tri-state open-drain output; data shifted out on SCK falling edge; high-impedance when CS high or HOLD active |
| WP (Pin 3) | Write-Protect Input | Hardware lock for STATUS register nonvolatile bits when WPEN = 1; no effect if WPEN = 0 |
| VSS (Pin 4) | Ground Reference | Primary return path for all I/O and core logic; must be low-impedance to minimize noise coupling into SPI timing |
| SI (Pin 5) | Serial Data Input | Latches instruction/address/data on SCK rising edge; requires setup/hold compliance per AC specs (e.g., 20 ns @ 5.5V) |
| SCK (Pin 6) | Serial Clock Input | Master-generated clock; defines timing for all SI sampling and SO updates; max 5 MHz with 2 μs rise/fall limits |
| HOLD (Pin 7) | Transaction Pause Control | Active-low suspend signal; must be asserted while SCK is low to avoid bus contention; tri-states SO immediately |
| VCC (Pin 8) | Supply Voltage | 2.5V–5.5V operation; 5.5V max absolute rating; decoupling capacitor required within 10 mm of VCC/VSS pins |
Key Features
| Feature | Design Value |
|---|---|
| Self-timed write cycles | Internal 6 ms erase/write completion - eliminates need for external timeout polling; WIP bit indicates busy state |
| Programmable block protection | BP0/BP1 bits configure 0%, 25%, 50%, or 100% array write-lock - enables selective calibration vs. firmware partitioning |
| HOLD pin functionality | Suspends ongoing SPI transfer without resetting address pointer - critical for interrupt-driven microcontroller hosts |
| AEC-Q100 Grade 0 qualification | Validated for 1,000 hours at +150°C - meets automotive powertrain and chassis module reliability requirements |
| Low-power standby current | 10 μA at +150°C and 5.5V - minimizes battery drain in always-on vehicle subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25160B-MAHL-T (Microchip) | Same 16 Kbit density, 32-byte page, and –40°C to +125°C rating; lacks AEC-Q100 qualification and 150°C operation | Targeted at commercial/industrial use; not validated for automotive under-hood deployment | Select 25LC160D-H/SN when operating above +125°C or requiring AEC-Q100 documentation |
| BR25H160FJ-WE2 (ROHM) | 16 Kbit SPI EEPROM with 10 million endurance, 40 MHz max clock, and –40°C to +125°C range; different pinout (8-lead TSSOP) | Higher speed and endurance, but no HOLD pin or 150°C support; requires PCB layout change | Choose 25LC160D-H/SN for drop-in replacement in existing SOIC designs needing extended temperature capability |
Compared with AT25160B-MAHL-T and BR25H160FJ-WE2, the 25LC160D-H/SN uniquely combines AEC-Q100 Grade 0 qualification, 150°C operation, HOLD functionality, and SOIC-SN pin compatibility - making it the only option for thermally demanding automotive modules requiring zero-layout-change upgrades.

FAQ
What is the maximum clock frequency supported by the 25LC160D-H/SN?
The 25LC160D-H/SN supports up to 5 MHz clock frequency when VCC is 4.5V–5.5V, and 3 MHz when VCC is 2.5V–4.5V. These limits are defined in Table 1-2 of the DS20002131D datasheet and ensure reliable setup/hold timing margins across the full –40°C to +150°C operating range. Exceeding these frequencies may cause read/write failures due to violated AC timing parameters like TCSS and Tsu.
Does the 25LC160D-H/SN support page write operations, and what is its page size?
Yes, the 25LC160D-H/SN supports page write operations with a fixed page size of 32 bytes. This is confirmed in the DEVICE SELECTION TABLE on page 2 of DS20002131D. Page writes allow up to 32 sequential bytes to be loaded before initiating the internal 6 ms write cycle - improving efficiency over byte-by-byte programming while requiring software to manage page boundaries to prevent data wraparound.
How does hardware write protection work on the 25LC160D-H/SN?
Hardware write protection on the 25LC160D-H/SN requires both WPEN = 1 (set via WRSR) and WP pin held low. When enabled, this blocks writes to nonvolatile STATUS register bits (BP0, BP1, WPEN) but permits normal memory writes unless block protection is also configured. The WP pin has no effect if WPEN = 0, allowing safe board-level grounding during prototyping without locking configuration registers.
Is the 25LC160D-H/SN qualified for automotive applications?
Yes, the 25LC160D-H/SN is AEC-Q100 qualified for Grade 0 (–40°C to +150°C), as explicitly stated in the Features section of DS20002131D. This qualification includes 1,000 hours of bias life testing at +150°C and full reliability characterization - making it suitable for engine control, transmission, and brake control modules where extended temperature operation is mandatory.
What is the endurance and data retention specification for the 25LC160D-H/SN?
The 25LC160D-H/SN guarantees >1,000,000 erase/write cycles and >200 years of data retention at +150°C, per Tables 1-2 and 1-3 in DS20002131D. These values are characterized (not tested 100%) but ensured through process and design controls. The 200-year retention at maximum temperature enables single-write calibration storage in automotive and industrial systems with multi-decade service life expectations.
