Standard Peripherals

The advantage of a 32 bit processor is having enough address space to layout the peripheral registers in a way that makes programming for the peripherals easy and reduce the number of instructions to required to implement drivers.
A wide range of peripherals are available:

Simple Counter
General Purpose I⁄O
JTAG
Timer
- Compare Unit (PWM)
- Capture Unit
Simple Fixed Baud Rate UART
Fractional Baud Rate UART
SPI
I2C
Instruction Cache
Data Cache
Memory Management Unit
Trace Buffer
Peripheral Bridge
Watchdog

In addition to these simple peripherals, there are also peripherals with more sophisticated functionality:

Instruction Cache
Data Cache
APB™ Bridge
AHB-Lite™ Bridge
MMU
Trace Buffer

Feature rich interface peripherals are also available:

Ethernet MAC (10/100)
USB 2.0 MAC
