Description

The TI AM438x high-performance processors are based on the ARM Cortex-A9 core.

The processors are enhanced with payment card peripherals and logical and physical security to help

customers meet payment card industry (PCI) requirements. The devices support high-level operating

The devices offer an upgrade to systems based on lower performance ARM cores, provide updated

peripherals, including memory options such as QSPI-NOR and LPDDR2, and support the security features

discussed below.

The processors contain the subsystems shown in the Functional Block Diagram, and a brief description of

each follows.

The processor subsystem is based on the ARM Cortex-A9 core, and the PowerVR SGX™ graphics

accelerator subsystem provides 3D graphics acceleration to support display and advanced user interfaces.

The programmable real-time unit subsystem and industrial communication subsystem (PRU-ICSS) is

separate from the ARM core and allows independent operation and clocking for greater efficiency and

flexibility. The programmable nature of the PRU-ICSS, along with their access to pins, events and all

system-on-chip (SoC) resources, provides flexibility in implementing fast real-time responses, specialized

data handling operations, custom peripheral interfaces, and in off-loading tasks from the other processor

cores of the SoC.

High-performance interconnects provide high-bandwidth data transfers for multiple initiators to the internal

and external memory controllers and to on-chip peripherals. The device also offers a comprehensive

clock-management scheme.

The on-chip analog to digital converter (ADC0) can couple with the display subsystem to provide an

integrated touch-screen solution. There is also an EMV-compliant ISO7816 interface (Smart Card)

interface and magnetic card controller (ADC1).

The RTC provides a clock reference on a separate power domain. The clock reference enables a battery-

backed clock reference.

The camera interface offers configuration for a single- or dual-camera parallel port.

The physical protection subsystem adds enclosure protection to the secure features offered by the

AM438x processors which include cryptography acceleration and secure boot. Enclosure protection helps

customers design products that detect when the casing is opened, and protect sensitive parts of the circuit

with a wire mesh. Tamper protection monitors voltage, temperature, and crystal frequency so system

designers can detect external attacks.

In addition, the partial ARM TrustZone allows system designers to configure memory for secure storage

and protect against software attacks.
