DS14539 Rev 1

•

Each tamper can be configured in two modes:

–

Hardware mode: immediate erase of secrets on tamper detection, including

backup registers erase

–

Software mode: erase of secrets following a tamper detection launched by

software

•

Any tamper detection can generate an RTC time stamp event.

•

TrustZone support:

–

Tamper secure or non-secure configuration.

–

Backup registers configuration in 3 configurable-size areas:

- 1 read/write secure area

- 1 write secure/read non-secure area

- 1 read/write non-secure area

•

Tamper configuration and backup registers privilege protection

•

Monotonic counter

Inter-integrated circuit interface (I2C)

The device embeds three I2C. Refer to Table 8 for the implemented features.

The I2C bus interface handles communications between the microcontroller and the serial

I2C bus. It controls all I2C bus-specific sequencing, protocol, arbitration and timing.

The I2C peripheral supports:

•

I2C-bus specification and user manual rev. 5 compatibility:

–

Slave and Master modes, multimaster capability

–

Standard-mode (Sm), with a bit rate up to 100 Kbit/s

–

Fast-mode (Fm), with a bit rate up to 400 Kbit/s

–

Fast-mode Plus (Fm+), with a bit rate up to 1 Mbit/s and 20 mA output drive I/Os

–

7- and 10-bit addressing modes, multiple 7-bit slave addresses

–

Programmable setup and hold times

–

Optional clock stretching

•

System management bus (SMBus) specification rev 3.0 compatibility:

–

Hardware PEC (packet error checking) generation and verification with ACK

control

–

Address resolution protocol (ARP) support

–

SMBus alert

•

Power system management protocol (PMBus) specification rev 1.3 compatibility

•

Independent clock: a choice of independent clock sources allowing the I2C

commun.ication speed to be independent from the PCLK reprogramming

•

Wake-up from Stop capability

•

Programmable analog and digital noise filters

•

1-byte buffer with DMA capability
