Power, memory and security¶

Handlers for the PF1550 PMIC, the AT25040B SPI EEPROM and the SE050 secure element.

Pf1550Handler¶

HAL handler for NXP PF1550 PMIC (I2C + optional strap GPIOs).

Header: handlers/pf1550/Pf1550Handler.h
Switch: HF_CORE_ENABLE_PF1550 (default OFF)
Driver: hf-pf1550-driver

Pf1550Handler(
    BaseI2c& i2c,
    BaseGpio* standby_gpio = nullptr,
    BaseGpio* usb_vbus_en_gpio = nullptr,
    BaseGpio* usb_otg_en_gpio = nullptr);

Group	Public methods

At25040Handler¶

SPI AT25040B handler — BaseSpi + optional /WP, lazy Probe.

Header: handlers/at25040/At25040Handler.h
Switch: HF_CORE_ENABLE_AT25040 (default OFF)
Driver: hf-at25040-driver

At25040Handler(BaseSpi& spi, BaseGpio* wp = nullptr);

Group	Public methods
All	`Probe()`, `LastRdsr()`, `Read()`, `Write()`, `ReleaseWriteProtect()`, `ParkWriteProtect()`

Se050Handler¶

HAL-level handler for the NXP SE050 / SE050A secure element (I²C, T=1oI2C).

Header: handlers/se050/Se050Handler.h
Switch: HF_CORE_ENABLE_SE050 (default OFF)
Driver: hf-se050-driver

Se050Handler(
    BaseI2c& i2c,
    const Se050HandlerConfig& config = Se050HandlerConfig{},
    BaseGpio* reset_gpio = nullptr,
    RtosMutex* bus_mutex = nullptr);

Group	Public methods
All	`Config()`, `EnsureInitialized()`, `IsPresent()`, `GetDevice()`
