— One High Speed (HS) USB 2.0 host port with integrated HS USB PHY
Miscellaneous interfaces:
— One-wire (OWIRE) port
— Two I2S/SSI/AC97 ports, supporting up to 1.4 Mbps each connected to the Audio Multiplexer
— Five UART RS232 ports, up to 4.0 Mbps each
— Two eCSPI (Enhanced CSPI) ports, up to 66 Mbps each plus CSPI port, up to 16.6 Mbps
— Three I
— Fast Ethernet controller IEEE 802.3, 10/100 Mbps
— Key pad port (KPP)
— Two pulse width modulators (PWM)
— GPIO with interrupt capabilities
— Secure JTAG controller (SJC)
Supporting DVFS techniques for low power modes, including auto slow architecture
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 32 kHz and 24 MHz oscillators
A total of four PLLs with the fourth PLL providing up to eight independently controllable outputs,
improving the ease of clocking control, especially for display and connectivity modules
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
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
(AUDMUX) providing four external ports
