i.MX53xA Automotive and Infotainment Applications Processors, Rev. 1

Freescale Semiconductor

Architectural Overview

•

Secure JTAG controller (SJC)—Protecting JTAG from debug port attacks by regulating or

blocking the access to the system debug features

•

Secure real-time clock (SRTC)—Tamper resistant RTC with dedicated power domain and

mechanism to detect voltage and clock glitches

•

Real-time integrity checker, version 3 (RTICv3)—RTIC type1, enhanced with SHA-256 engine

•

SAHARAv4 Lite—Cryptographic accelerator that includes true random number generator

(TRNG)

•

Security controller, version 2 (SCCv2)—Improved SCC with AES engine, secure/non-secure

RAM and support for multiple keys as well as TZ/non-TZ separation

•

Central security unit (CSU)—Enhancement for the IIM (IC Identification Module). CSU is

configured during boot by e-fuses, and determines the security level operation mode as well as the

TrustZone (TZ) policy

•

Advanced High Assurance Boot (A-HAB)—HAB with the next embedded enhancements:

SHA-256, 2048-bit RSA key, version control mechanism, warm boot, CSU, and TZ initialization

NOTE

The actual feature set depends on the part number as described in Table 1.

Functions such as video hardware acceleration, 2D and 3D hardware

graphics acceleration, and MacrovisionTM video copy protection may not be

enabled for specific part numbers.
