18 NXP Semiconductors
Modules list
QuadTimer1
QuadTimer2
QuadTimer3
QuadTimer4
QuadTimer Timer Peripherals The quad-timer provides four time channels with a
variety of controls affecting both individual and
multi-channel features.Specific features include
up/down count, cascading of counters, programmable
module, count once/repeated, counter preload,
compare registers with preload, shared use of input
signals, prescaler controls, independent
capture/compare, fault input control, programmable
input filters, and multi-channel synchronization.
RDC Resource Domain
Controller
Security The RDC provides robust support for the isolation of
processing domain to prevent one core from accessing
another’s peripherals, to control access rights to
common memory and provide hardware enforcement of
semaphore based locking of shared peripherals.
For single system use case, RDC can be disabled and
AIPS-TZ/DEXSC can be bypassed. For dual system
case, RDC can be configured and locked each core
starts their own image.
ROMCP ROM Controller with
Patch
Memories and
Memory Controllers
The ROMCP acts as an interface between the Arm
advanced high-performance bus and the ROM. The
on-chip ROM is only used by the Cortex-M7 core during
boot up. Size of the ROM is 256 KB.
RTC OSC Real Time Clock
Oscillator
Clock Sources and
Control
The RTC OSC provides the clock source for the
Real-Time Clock module. The RTC OSC module, in
conjunction with an external crystal, generates a 32.678
kHz reference clock for the RTC.
SAI1
SAI2
SAI3
SAI4
Synchronous Audio
Interface
Multimedia
Peripherals
The SAI module provides a synchronous audio interface
(SAI) that supports full duplex serial interfaces with
frame synchronization, such as I2S, AC97, TDM, and
codec/DSP interfaces.
SEMA4 Semaphores System Control The SEMA4 module implements hardware-enforced
semaphores as an IPS-mapped slave peripheral device
and provides 16 hardware-enforced gates in a
dual-processor configuration.
SEMC Smart External Memory
Controller
Memory and
Memory Controller
The SEMC is a multi-standard memory controller
optimized for both high-performance and low pin-count.
It can support multiple external memories in the same
application with shared address and data pins. The
interface supported includes SDRAM, NOR Flash,
SRAM, and NAND Flash, as well as 8080 display
interface.
SNVS Secure Non-Volatile
Storage
Security Secure Non-Volatile Storage, including Secure Real
Time Clock, Security State Machine, Master Key
Control, and Violation/Tamper Detection and reporting.
SPDIF Sony Philips Digital
Interconnect Format
Multimedia
Peripherals
A standard audio file transfer format, developed jointly
by the Sony and Phillips corporations. Has Transmitter
and Receiver functionality.
