i.MX31/i.MX31L Advance Information, Rev. 1.4
This FIR is capable of establishing a 0.576 Mbit/s, 1.152 Mbit/s or 4
Mbit/s half duplex link via a LED and IR detector. It supports 0.576
Mbit/s, 1.152 Mbit/s medium infrared (MIR) physical layer protocol
and 4Mbit/s fast infrared (FIR) physical layer protocol defined by
IrDA, version 1.4.
The GPIO provides 32 bits of bidirectional, general purpose I/O.
This peripheral provides dedicated general-purpose pins that can
be configured as either inputs or outputs.
The GPT is a multipurpose module used to measure intervals or
generate periodic output.
The GPU provides hardware acceleration for 2D and 3D graphics
algorithms.
The I2C provides serial interface for controlling the Sensor Interface
and other external devices. Data rates of up to 100 Kbits/s are
supported.
The IIM provides an interface for reading—and in some cases,
programming, and overriding identification and control information
stored in on-chip fuse elements.
The IPU supports video and graphics processing functions in the
i.MX31 and i.MX31L and interfaces to video, still image sensors,
and displays.
The KPP is used for key pad matrix scanning or as a general
purpose I/O. This peripheral simplifies the software task of scanning
a keypad matrix.
The MPEG-4 encoder accelerates video compression, following the
MPEG-4 standard
The PCMCIA Host Adapter provides the control logic for PCMCIA
socket interfaces.
The PWM has a 16-bit counter and is optimized to generate sound
from stored sample audio images. It can also generate tones.
The RNGA module is a digital integrated circuit capable of
generating 32-bit random numbers. It is designed to comply with
FIPS-140 standards for randomness and non-determinism.
The RTC module provides a current stamp of seconds, minutes,
hours, and days. Alarm and timer functions are also available for
programming. The RTC support dates from the year 1980 to 2050.
The RTIC ensures the integrity of the peripheral memory contents
and assists with boot authentication.
