Freescale Semiconductor

The i.MX28 can be connected to a variety of external devices such as high-speed USB2.0 OTG, CAN,

10/100 Ethernet, and SD/SDIO/MMC.

1.1

Device Features

The following lists the features of the i.MX28:

•

ARM926EJ-S CPU running at 454 MHz:

— 16-Kbyte instruction cache and 32-Kbyte data cache

— ARM embedded trace macrocell (CoreSight™ ETM9™)

— Parallel JTAG interface

•

128 KBytes of integrated low-power on-chip SRAM

•

128 KBytes of integrated mask-programmable on-chip ROM

•

1280 bits of on-chip one-time-programmable (OCOTP) ROM

•

16-bit mobile DDR (mDDR) (1.8 V), DDR2 (1.8 V) and LV-DDR2 (1.5 V), up to 205 MHz DDR

clock frequency with voltage overdrive

•

Support for up to eight NAND flash memory devices with up to 20-bit BCH ECC

•

Four synchronous serial ports (SSP) for SDIO/MMC/MS/SPI. Two can be used for

SDIO/MMC/MS interfaces (supports SD2.0, eMMC4.4 and MSPro), and all can be used for the

SPI interface.

•

10/100-Mbps Ethernet MAC compatible with IEEE Std 802.3™, supporting

IEEE Std 1588™-compatible hardware timestamp. Also supports 50-MHz/25-MHz clock output

for external Ethernet PHY.

•

Two 2.0B protocol-compatible Controller Area Network (CAN) interfaces

•

One USB2.0 OTG device/host controller and PHY

•

One USB2.0 host controller and PHY

•

LCD controller, up to 24-bit RGB (DOTCK) modes and 24-bit system-mode

•

Pixel-processing pipeline (PXP) supports full path from color-space conversion, scaling,

alpha-blending to rotation without intermediate memory access.

•

SPDIF transmitter

•

Dual serial audio interface (SAIF) to support full-duplex transmit and receive operations; each

SAIF supports three stereo pairs

•

Five application Universal Asynchronous Receiver-Transmitters (UARTs), up to 3.25 Mbps with

hardware flow control

•

One debug UART operating at up to 115 Kb/s using programmed I/O

•Two I2C master/slave interfaces, up to 400 kbps

•

Four 32-bit timers and a rotary decoder

•

Eight Pulse Width Modulators (PWMs)

•

Real-time clock (RTC)

•

GPIO with interrupt capability
