MikroElektronika EERAM 3.3V Click
Overview
EERAM 3.3V Click [1] is a compact add-on board based on the Microchip 47L16 [2] 2KB I2C SRAM with automatic EEPROM backup (EERAM).
The 47L16 exposes 2048 bytes of SRAM over I2C at address 0x50. Writes are immediate with no page-crossing restrictions or write-cycle delays. SRAM contents are automatically backed up to internal EEPROM on power loss, providing non-volatile storage without explicit driver involvement.
The shield overlay sets the eeprom-0 alias, allowing applications to access the device through
the standard Zephyr EEPROM API via the generic atmel,at24 driver.
Requirements
This shield can only be used with a board that provides a mikroBUS™ socket and defines a
mikrobus_i2c node label for the mikroBUS™ I2C interface. See Shields for more details.
Programming
Set --shield mikroe_eeram_33v_click when you invoke west build. For example:
# From the root of the zephyr repository
west build -b frdm_mcxn947/mcxn947/cpu0 --shield mikroe_eeram_33v_click samples/drivers/eeprom
