製品概要

概要

The X-NUCLEO-PGEEZ1 expansion board is designed for the M95P32 series SPI page EEPROM for data reading and writing.

This expansion board allows developers to evaluate the new memory page EEPROM through a single/dual/quad SPI interface.

It acts as an external storage device that can be used to store data, such as manufacturing traceability, calibration, user settings, error flags, data logs, and monitoring data to build more flexible and accurate applications.

The X-NUCLEO-PGEEZ1 expansion board can be plugged on top of an STM32 Nucleo-144 (via ZIO connectors) or STM32 Nucleo-64 (via Arduino^® UNO R3 connectors).

機能一覧
Up to 32-Mbits SPI bus embedded page EEPROM

50 MHz read single output

80 MHz fast read single/dual/quad output with one dummy byte

Page program with buffer load

Ultra-low power consumption

Free comprehensive development firmware library and sample implementation available when the X-NUCLEO-PGEEZ1 expansion board is plugged on top of a NUCLEO-F401RE, NUCLEO-L053R8, NUCLEO-G474RE, or NUCLEO-H743ZI development board

Developer can choose and solder an EEPROM to be tested using the evaluation software provided
