Global TrustZone controller (GTZC)

GTZC is used to configure TrustZone and privileged attributes within the full system.

The GTZC includes different sub-blocks:

•

TZSC: TrustZone security controller

Defines the secure/privilege state of slave/master peripherals. The TZSC block informs

some peripherals (such as RCC or GPIO) about the secure status of each securable

peripheral.

•

TZIC: TrustZone illegal access controller

Gathers all security illegal access events in the system and generates a secure

interrupt towards NVIC.

•

MPCBB: block-based memory protection controller

Controls secure states of all memory blocks (512-byte pages) of the associated SRAM.

This peripheral configures the internal RAM in a TrustZone system product having

segmented SRAM with programmable-security and privileged attributes.

The GTZC main features are:

•

Independent 32-bit AHB interfaces for TZSC, TZIC and MPCBB

•

Secure and nonsecure access supported for privileged/unprivileged part of TZSC

•

Set of registers to define product security settings:

–

Secure/privilege access mode for securable peripherals

–

Secure/privilege access mode for securable memories

–

Illegal access interrupt notification

2.4 GHz RADIO

The 2.4 GHz RADIO is ultra-low-power, operating in the 2.4 GHz ISM band. It provides

Bluetooth LE 1 Mbps coded, 1 Mbps, and 2 Mbps noncoded GFSK, and IEEE802.15.4 chip

rate 2 Mchip/s, spreading mode DSSS, data rate 125 kbps and 250 kbps, O-QPSK-C

modulation. It is compliant with the Bluetooth 5.4, Matter, Thread, and Zigbee specifications,

and with radio regulations including ETSI EN 300 328, EN 300 440, EN 301 489-17, ARIB

STD-T66, FCC CFR47 part 15 section 15.205, 15.209, 15.247 and 15.249, IC RSS-139 and

RSS-210.
