Http://www.rosoo.net/a/200911/7966.html dm9000 (a) is a fully integrated, powerful, cost-effective Fast Ethernet MAC controller, it has a general-purpose processor interface, an EEPROM interface, a 10/100 PHY and a 16 kb SRAM (13 KB as the receiving FIFO, 3 kb as the sending FIFO ). It uses a single power supply and is compatible with 3.3 V and 5 v io Interface levels. Dm9000 (a) also supports the media independent interface (media-independent) interf

Abstract The problem of capacity calculation is encountered when debugging the SDRAM using the nio ii. The following is an introduction: Introduction Question 1: What are dram, SRAM, and SDRAM? A: The terms are explained as follows: DRAM -------- the dynamic access device immediately. data can be stored only after constant refreshing, and the row and column addresses are reused. Many of them have page modes.

16-bit port of dsPIC6014A is used as the low position of the SRAM address bus. The 3-bit high is controlled by the other 3 I/O bits, the eight sub-buckets are used to save the collected audio signal data and temporary data for digital signal processing. The RF transceiver module uses nRF24L01 to exchange data with the CPU through the SPI interface. The audio signal generator uses commercially available Sta

The price of this board is $69, considering the cost of integrating embedded Linux devices, Arduino and WiFi transmitters, and other Expansion Boards into one Development Board, this price suits the psychological price of most of us. 2. beaglebone black Beaglebone blackbeaglebone black is one of the few Linux development boards that can be started in

I2S transmission. The audio data can be 8/16/32bit and the sampling rate ranges from 8 kHz to 192 kHz. I2C: Two I2C controllers are supported. UART: Supports four UART ports, DMA and interrupt modes. uart0/1/2 also supports the irda1.0 function. UART speed up to 3 Mbps. Gpio: Universal gpio port, function reuse. IRDA: Independent IrDA controller, compatible with irda1.1, supports the Mir and fir modes. SPI: Supports full-featured

The common configuration modes for Xilinx FPGAs are 5 classes: main string mode, slave string mode, Select MAP mode, Desktop configuration, and direct SPI configuration.At present, the two companies with the highest market share of FPGA and the FPGA produced by Altera are based on the

Address: http://blog.163.com/gene_lu/blog/static/64025421201111872144184/ We skip all the descriptions of arm and directly go to the questions most concerned by engineers.To design an ARM-based SOC, we must first understand an ARM-based SoC structure. Figure 1 shows a typical SOC structure:Figure 1From figure 1, we can understand the basic structure of the SOC: ARM core: arm966e AMBA Bus: AHB + APB Peripheral IP (periph

The mt7697 is a highly integrated monolithic chip with application processor, low power 1x111n single-frequency Wi-Fi subsystem, Bluetooth subsystem, and power management unit. I do not know. The application processor subsystem contains an arm cortical-m4 with a floating-point MCU. It also includes many peripheral devices, including Uart,i2c,spi,i2s,pwm,irda and auxiliary ADCs. It also includes embedded Sram
