Product details
Overview
M45PE10-VMP6TG from STMicroelectronics is a 1-Mbit serial flash memory IC with SPI interface, 3.3 V supply voltage, 5 MHz max clock frequency, 8 ms typical page program time, and industrial temperature range (−40°C to +85°C); used for firmware storage in embedded microcontroller systems requiring nonvolatile code retention.
For engineers reviewing the M45PE10-VMP6TG datasheet, M45PE10-VMP6TG pinout, M45PE10-VMP6TG application, or M45PE10-VMP6TG equivalent, key selection criteria include SPI timing compliance, write endurance (100k cycles), data retention (20 years), and SO8 package compatibility with PCB layout constraints for space-constrained IoT edge nodes.
Technical Context
This device implements a standard SPI-compatible quad-wire interface (SI/SO/CLK/CS) with dual I/O and quad I/O support enabled via configuration registers. It uses NOR flash architecture with uniform 4-Kbyte sectors and a single 256-byte page for programming.
Command-set compatibility follows JEDEC JESD216 standard for SFDP, supporting automatic read mode entry and status register polling. Erase granularity includes sector (4 Kbyte), block (32/64 Kbyte), and chip-wide operations, all executed internally without external timing control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Mbit (128 Kbyte) organized as 256 pages × 256 bytes; supports full firmware image storage for small MCUs like STM32F0 or PIC18. |
| Interface | SPI-compatible 4-wire (CS, CLK, SI, SO); enables direct connection to MCU SPI peripherals without level shifters at 3.3 V. |
| Max Clock Frequency | 5 MHz in standard SPI mode; limits sustained read throughput to ~0.625 MB/s, suitable for boot-time code fetch, not streaming. |
| Write Endurance | 100,000 program/erase cycles per sector; ensures reliable field updates over 10+ years in remote sensor node firmware upgrades. |
| Data Retention | 20 years at +85°C; guarantees firmware integrity across full industrial temperature lifecycle without refresh. |
| Supply Voltage | 2.7 V to 3.6 V; compatible with standard 3.3 V LDO rails and tolerant of brown-out conditions down to 2.7 V. |
Pinout & Package
Package: SO8 (Small Outline, 150 mil width), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 / /CS | Chip Select Input | Active-low enable; must be driven low before SPI clock starts; controls device participation in bus transactions. |
| 2 / DO (SO) | Serial Data Output | Tri-state open-drain output; carries read data and status bits; requires external pull-up for proper logic high. |
| 3 / /WP | Write Protect Input | Hardware lock for top/bottom 4-Kbyte sectors; tied high for full programmability, grounded to freeze critical boot code. |
| 4 / GND | Ground Reference | Signal and power return path; must be connected to system ground plane with low-impedance trace. |
| 5 / DI (SI) | Serial Data Input | CMOS-level input for commands, addresses, and write data; sampled on rising CLK edge. |
| 6 / /HOLD | Hold Input | Pauses ongoing read transfer without deselecting device; useful during multi-byte reads interrupted by higher-priority tasks. |
| 7 / CLK | Serial Clock Input | Master-generated clock; rising edge latches DI, falling edge samples DO; determines maximum SPI transaction speed. |
| 8 / VCC | Power Supply | 3.3 V nominal supply; bypass capacitor (100 nF) required within 5 mm of pin for stable internal charge pump operation. |
Key Features
| Feature | Design Value |
|---|---|
| Single Power Supply | Operates from 2.7–3.6 V only-eliminates need for separate VCC/VPP rails or external high-voltage generators. |
| Software Write Protection | Status register bits enable/disable write/erase globally or per-sector-supports secure OTA update partitioning. |
| Page Program Mode | 256-byte page buffer allows burst programming without reissuing address; reduces MCU SPI overhead by 90% vs. byte-wise writes. |
| Power-down Mode | Standby current < 1 µA when /CS held high; extends battery life in always-on sensor nodes between wake cycles. |
Applications
| Firmware Storage for Cortex-M0 Microcontrollers | Boot Code Retention in Industrial PLCs |
|---|---|
Use Scenario: Storing bootloader and application firmware for STM32F030-based motor control modules deployed in factory automation cabinets. IC Role / Device Role / Timing Role: Nonvolatile storage peripheral accessed via SPI during cold start; provides deterministic 200 µs access latency to first instruction. Use Value: Enables field firmware updates without replacing MCU; 100k erase cycles support ≥2 updates/month for 4+ years. | Use Scenario: Holding configuration parameters and safety-critical startup routines in DIN-rail mounted PLC controllers operating continuously at 60°C ambient. IC Role / Device Role / Timing Role: Dedicated boot memory mapped to MCU's external memory interface; retains valid code after 10-year shelf life. Use Value: 20-year data retention at +85°C ensures no unexpected boot failure due to bit rot during extended deployment. |

Use Scenario: Storing AES-128 keys and calibration coefficients in EN13757-compliant gas meters subjected to thermal cycling from −25°C to +70°C. IC Role / Device Role / Timing Role: Isolated security partition with hardware /WP pin lock; prevents accidental overwrite during meter firmware upgrade. Use Value: Sector-level write protection ensures cryptographic keys remain intact even if application firmware is corrupted. | Use Scenario: Caching delta patches for over-the-air firmware updates in LoRaWAN end-nodes powered by coin-cell batteries. IC Role / Device Role / Timing Role: Temporary patch staging area; erased and rewritten once per update cycle using 4-Kbyte sector erase. Use Value: 8 ms page program time enables full 256-byte patch commit in <10 ms, minimizing radio-on time and extending battery life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF011-SSH-T | Same density (1 Mbit), but supports 85 MHz DTR mode; lacks /HOLD pin and has different status register layout. | Higher bandwidth needed for video frame buffering; incompatible command set breaks existing SPI driver stack. | Select only if redesigning firmware to support Atmel's proprietary DTR protocol and verifying /HOLD removal does not impact interrupt latency. |
| S25FL008A0XMFI010 | 8-Mbit capacity, 104 MHz max clock, supports 4-byte addressing; requires different sector erase timing and SFDP parsing. | Used where future firmware growth headroom is mandatory; larger die size increases PCB footprint by 30%. | Choose when scaling beyond 1 Mbit is confirmed; verify MCU SPI peripheral supports 4-byte addressing mode and extended erase times. |
Compared with AT25DF011-SSH-T and S25FL008A0XMFI010, M45PE10-VMP6TG offers proven JEDEC SPI compatibility, minimal pin count, and predictable 5 MHz timing-ideal for cost-sensitive, space-constrained designs where firmware size is fixed and unchanged across product lifetime.

FAQ
Is M45PE10-VMP6TG compatible with standard SPI mode 0 (CPOL=0, CPHA=0)?
Yes. The device operates exclusively in SPI mode 0: clock polarity is low when idle (CPOL=0), and data is sampled on the first clock edge (CHPHA=0). All commands-including Read Status Register, Page Program, and Sector Erase-follow this timing, ensuring drop-in compatibility with generic MCU SPI peripherals without mode configuration.
Does M45PE10-VMP6TG support Quad SPI (QSPI) or Dual SPI modes?
No. M45PE10-VMP6TG supports only standard single-data-rate SPI (SI/SO) and does not implement dual or quad I/O protocols. It lacks dedicated QIO/DIO pins and corresponding command opcodes (e.g., 0x6B or 0x3B). Its maximum throughput is limited to 5 Mbps in standard mode.
What is the minimum VCC voltage required for reliable write operations?
Reliable page program and sector erase operations require VCC ≥ 2.7 V. Below this threshold, internal charge pumps cannot generate sufficient voltage for Fowler-Nordheim tunneling, resulting in incomplete programming or erase failures. The device will accept commands but may report WIP=1 indefinitely or return incorrect status register values.
Can the /WP pin be left unconnected in designs without hardware write protection?
No. The /WP pin is active-low and internally pulled up; however, leaving it floating risks noise-induced partial sector lock. STMicroelectronics datasheet specifies tying /WP to VCC via a 10-kΩ resistor for full write enable. Direct VCC connection is acceptable but increases susceptibility to ESD transients on that line.
