STSAFE-A110’s environment

The STSAFE-A110 comes with a host integration code tested with STMicroelectronics (ST)

STM32 general-purpose MCUs. It can also be ported to a wide range of general-purpose

microcontrollers or microprocessors. This integration code includes a command wrapper

and examples for the most common generic use cases.

The STSAFE-A110 is available prepersonalized with generic data profiles for evaluation or

prototyping.

ST also offers and recommends secure provisioning services for key generation and

storage of customer leaf certificates in a secure, certified environment.

The STSAFE-A110 are delivered with an ST CA certificate that allows authenticity

verification of the leaf certificates present in each STSAFE-A110 device.

VCC

Supply voltage

The 1.62 to 5.5 V supply voltage is supported for powering all

internal STSAFE-A110 functions.

GND

Supply and

signals ground

Ground reference pin for power and all I/O signals.

RESET

This input signal is used to reset STSAFE-A110. The RESET pin is

pull-down by default meaning that the device is reset if connected to

ground or if the pin is floating. The device is active if the RESET pin

is tied high.
