Introduction
• Expansion cards:
— Four SD/MMC card ports: three supporting 416 Mbps (8-bit i/f) and one enhanced port
supporting 832 Mbps (8-bit, eMMC 4.4).
• USB
— High-speed (HS) USB 2.0 OTG (up to 480 Mbps), with integrated HS USB PHY
— Three USB 2.0 (480 Mbps) hosts:
– High-speed host with integrated on-chip high-speed PHY
– Two high-speed hosts for external HS/FS transceivers through ULPI/serial, support IC-USB
• Automotive environment interfaces:
— Two controller area network (FlexCAN) interfaces, 1 Mbps each
— Media local bus or MediaLB (MLB) provides interface to most networks (50 Mbps)
— Enhanced serial audio interface (ESAI), up to 1.4 Mbps each channel
• Miscellaneous interfaces:
— One-wire (OWIRE) port
— Three I2S/SSI/AC97ports, supporting up to 1.4 Mbps, each connected to audio multiplexer
(AUDMUX) providing four external ports.
— Five UART RS232 ports, up to 4.0 Mbps each. One supports 8-wire, the other four support
4-wire.
— Two high speed enhanced CSPI (ECSPI) ports plus one CSPI port
— Three I2C ports, supporting 400 kbps
— Fast Ethernet controller, IEEE1588 V1 compliant, 10/100 Mbps
— Sony Phillips Digital Interface (SPDIF), Rx and Tx
— Key pad port (KPP)
— Two pulse-width modulators (PWM)
— GPIO with interrupt capabilities
— Secure JTAG controller (SJC)
The system supports efficient and smart power control and clocking:
• Power gating SRPG (State Retention Power Gating) for ARM core and Neon
• Support for various levels of system power modes
• Flexible clock gating control scheme
• On-chip temperature monitor
• On-chip oscillator amplifier supporting 32.768 kHz external crystal
• On-chip LDO voltage regulators for PLLs
Security functions are enabled and accelerated by the following hardware:
• ARM TrustZone including the TZ architecture (separation of interrupts, memory mapping, and so
on)
