• ARM7TDMI-S processor, running at up to 72 MHz.
• 512 kB on-chip flash program memory with In-System Programming (ISP) and In-Application Programming (IAP) capabilities. Flash program memory is on the ARM local bus for high performance CPU access.
• 64 kB of SRAM on the ARM local bus for high performance CPU access.
• 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.
• 16 kB SRAM for general purpose DMA use also accessible by USB.
• Dual Advanced High-performance Bus (AHB) system that provides for simultaneous Ethernet DMA, USB DMA, and program execution from on-chip flash with no contention between those functions. A bus bridge allows the Ethernet DMA to access the other AHB subsystem.
• EMC provides support for static devices such as flash and SRAM as well as off-chip memory mapped peripherals.
• Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts.
• General Purpose DMA controller (GPDMA) on AHB that can be used with the SSP serial interfaces, the I2S port, and the Secure Digital/MultiMediaCard (SD/MMC) card port, as well as for memory-to-memory transfers.
• Serial interfaces:
  • Ethernet MAC with associated DMA controller. These functions reside on an independent AHB.
  • USB 2.0 full-speed device with on-chip PHY and associated DMA controller.
  • Four UARTs with fractional baud rate generation, one with modem control I/O, one with IrDA support, all with FIFO.
  • CAN controller with two channels.
  • SPI controller.
  • Two SSP controllers, with FIFO and multi-protocol capabilities. One is an alternate for the SPI port, sharing its interrupt and pins. These can be used with the GPDMA controller.
  • Three I2C-bus interfaces (one with open-drain and two with standard port pins).
  • I2S (Inter-IC Sound) interface for digital audio input or output. It can be used with the GPDMA.
• Other peripherals:
  • SD/MMC memory card interface.
  • 104 General purpose I/O pins with configurable pull-up/down resistors.
  • 10-bit ADC with input multiplexing among 6 pins.
  • 10-bit DAC.
  • Four general purpose timers/counters with a total of 8 capture inputs and 10 compare outputs. Each timer block has an external count input.
  • One PWM/timer block with support for three-phase motor control. The PWM has two external count inputs.
  • Real-Time Clock (RTC) with separate power pin, clock source can be the RTC oscillator or the APB clock.
  • 2 kB SRAM powered from the RTC power pin, allowing data to be stored when the rest of the chip is powered off.
  • WatchDog Timer (WDT). The WDT can be clocked from the internal RC oscillator, the RTC oscillator, or the APB clock.
• Standard ARM test/debug interface for compatibility with existing tools.
• Emulation trace module supports real-time trace.
• Single 3.3 V power supply (3.0 V to 3.6 V).
• Three reduced power modes: idle, sleep, and power-down.
• Four external interrupt inputs configurable as edge/level sensitive. All pins on port 0 and port 2 can be used as edge sensitive interrupt sources.
• Processor wake-up from Power-down mode via any interrupt able to operate during Power-down mode (includes external interrupts, RTC interrupt, USB activity, Ethernet wake-up interrupt).
• Two independent power domains allow fine tuning of power consumption based on needed features.
• Each peripheral has its own clock divider for further power saving.
• Brownout detect with separate thresholds for interrupt and forced reset.
• On-chip power-on reset.
• On-chip crystal oscillator with an operating range of 1 MHz to 24 MHz.
• 4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as the system clock. When used as the CPU clock, does not allow CAN and USB to run.
• On-chip PLL allows CPU operation up to the maximum CPU rate without the need for a high frequency crystal. May be run from the main oscillator, the internal RC oscillator, or the RTC oscillator.
• Versatile pin function selections allow more possibilities for using on-chip peripheral functions.
