IMX233-OLinuXino-MINI user's manual
— High-speed memory copy
Three Universal Asynchronous Receiver-Transmitters (UARTs)
— Two high-speed application UARTs operating up to 3.25 Mb/s with hardware flow
control and dual DMA.
— Debug UART operates at up to 115Kb/s using programmed I/O.
I2C Master/Slave
— DMA control of an entire EEPROM or other device read/write transaction without CPU
intervention
Dual Synchronous Serial Ports (for SPI, MMC, SDIO, Triflash)
— 1-bit, 4-bit and 8-bit MMC/SD/SDIO modes
— Compliant with SDIO Rev. 2.0
— SPI with single, dual and quad modes.
Four-Channel 16-Bit Timer with Rotary Decoder
Five-Channel Pulse Width Modulator (PWM)
Real-Time Clock
— Alarm clock can turn the system on.
— Uses the existing 24-MHz XTAL for low cost or optional low power crystal (32.768 kHz
or 32.0 kHz), customer-selectable via OTP.
Customer-Programmable One-Time-Programmable (OTP) ROM via Integrated eFuse Block
— Resistor-less boot mode selection
— 128-bit boot mode crypto key
— Boot mode specification of NAND characteristics for device that the customer is
soldering to the board. This means no more costly delays waiting for new device support in t
he boot ROM.
— Fully software-programmable and accessible
Flexible I/O Pins
— All digital pins have drive-strength controls
— Most non-EMI digital pins have general-purpose input/output (GPIO) mode.
