Product details

Overview

X-NUCLEO-PGEEZ1 from STMicroelectronics is an STM32 Nucleo-compatible expansion board for evaluating the M95P32 series 32-Mbit SPI page EEPROM, supporting single/dual/quad SPI interfaces up to 80 MHz, with ultra-low power consumption and on-board jumper-configurable voltage selection (1.8 V / 3.3 V) for compatibility across NUCLEO-F401RE, NUCLEO-L053R8, NUCLEO-G474RE, and NUCLEO-H743ZI development platforms.

For engineers reviewing the X-NUCLEO-PGEEZ1 datasheet, X-NUCLEO-PGEEZ1 pinout, X-NUCLEO-PGEEZ1 application, or X-NUCLEO-PGEEZ1 equivalent, this board enables rapid validation of SPI EEPROM integration in traceability, calibration, error logging, and user settings storage-especially where flexible external non-volatile memory is required alongside STM32 MCU firmware development.

Technical Context

The board implements dual socketed SO8N footprint for M95P32-series SPI page EEPROMs, with configurable chip select routing (U1_CS/U2_CS), dedicated SPI signal routing (MOSI/MISO/SCLK/WPn/HOLD), and hardware-selectable IOREF voltage (1.8 V or 3.3 V) via jumpers J18–J20 to match host Nucleo board logic levels.

It provides direct ZIO (Nucleo-144) and Arduino® UNO R3 (Nucleo-64) connectivity, supports buffer-loaded page programming, and includes test points (TP1–TP13), status LEDs (LED1/LED2), user switches (SW1/SW2), and current measurement pads for real-time power profiling during EEPROM read/write cycles.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Type	SPI page EEPROM based on M95P32 series, enabling byte/page erase and program without block-level constraints.
Max SPI Clock	80 MHz fast read (single/dual/quad mode with one dummy byte), enabling high-throughput data logging at ≤100 ns per byte.
Interface Modes	Configurable single/dual/quad SPI via hardware pin mapping (DQ0–DQ3), supporting legacy and bandwidth-optimized protocols.
Power Supply Options	IOREF selectable between 1.8 V and 3.3 V using jumpers J18–J20, ensuring safe interfacing with low-voltage MCUs like STM32L053R8.
Board Connectivity	ZIO connector (Nucleo-144) and Arduino® UNO R3 header (Nucleo-64), enabling plug-and-play use without soldering or adapter cables.
On-board Features	Two user LEDs (PD15, PE11), two tactile switches (PA9, PG14), test points for all SPI signals and VDD, and dual SO8N sockets for EEPROM evaluation.

FAQ

Does X-NUCLEO-PGEEZ1 require external power or draw from the Nucleo board?

No external power is required. The board draws regulated 3.3 V or 5 V from the host Nucleo board via VIN/3V3 pins and uses jumper-selectable IOREF (1.8 V or 3.3 V) to match the MCU's IO voltage, ensuring safe level translation without additional regulators or supplies.

Can both SO8N sockets be used simultaneously for dual EEPROM operation?

No. The board routes only one set of SPI signals (MOSI/MISO/SCLK/WPn/HOLD/CS) to the host MCU at a time. U1_CS and U2_CS are separate, but shared bus signals mean only one EEPROM can be active per configuration-dual independent operation requires custom firmware arbitration and signal isolation not provided on-board.

Which STM32 Nucleo boards are officially supported with full firmware library compatibility?

Full firmware library and sample implementations are validated for NUCLEO-F401RE, NUCLEO-L053R8, NUCLEO-G474RE, and NUCLEO-H743ZI. These boards provide compatible ZIO or Arduino® headers, correct SPI peripheral mapping, and sufficient GPIO resources for CS, WP, and HOLD control as defined in ST's X-CUBE-EEPROM software package.

Is the M95P32 EEPROM pre-soldered, or must it be added by the user?

No EEPROM is pre-soldered. The board provides two SO8N footprints (U1 and U2) with zero-ohm resistors and jumpers to route signals to either socket. Users must solder their chosen M95P32-series EEPROM (e.g., M95P32-IXMNT/E) and configure jumpers (J13/J14) to select the active device before use.
