Features
Freescale Semiconductor
4
Six-channel DMA controller
Provides a wide range of frequency multiplications (1 to 255), predivider factors (1 to 31), PLL
feedback multiplier (2 or 4), Output divide factor (1, 2, or 4) and a power-saving clock divider
(2i: i = 0 to 7) to reduce clock noise
Internal address tracing support and OnCE for Hardware/Software debugging
JTAG port, supporting boundary scan, compliant to IEEE 1149.1
Very low-power CMOS design, fully static design with operating frequencies down to DC
STOP and WAIT low-power standby modes

Peripheral
Modules
Enhanced Serial Audio Interface (ESAI): up to 4 receiver pins and up to 6 transmitter pins, master
or slave. I2S, Sony, AC97, network, and other programmable protocols.
Enhanced Serial Audio Interface I (ESAI_1): up to 4 receiver pins and up to 6 transmitter pins,
master or slave. I2S, Sony, AC97, network and other programmable protocols. Note: Available in
the 80-pin package only.
Serial Host Interface (SHI): SPI and I2C protocols, 10-word receive FIFO, support for 8, 16, and
24-bit words. Three noise reduction filter modes.
Triple Timer module (TEC)
Most pins of unused peripherals may be programmed as GPIO pins. Up to 47 pins can be
configured as GPIO on the 80 pin package and 20 pins on the 52 pin package.
