S3C2440A Development Board-Samsung ARM9 Development Board-Longren Embedded System Development

S3C2440A Development Board ARM9　ARM9 Development Board Embedded Embedded system development

Main features: The S3C2440A development board is developed, designed and manufactured by Shenzhen Longren Computer Embedded System Development Co., Ltd. The S3C2440A has an industrial-grade operating temperature range and is suitable for harsh occasions. S3C2440A has a main frequency of up to 400MHz and a maximum of 533MHz. It has low power consumption and high performance. The development board is suitable for the development and evaluation of multimedia terminals such as PDAs, portable media players, and satellite navigation systems. It can also be used as a teaching tool for embedded operating systems and embedded hardware design. At present, a large number of products on the market use this chip, which is cheap and has sufficient supply.

S3C2440A is an ARM9 processor, and the 2440A development board is also the Samsung ARM9 series development board

2440A development board hardware introduction:

1: Processor: S3C2440A- 40 400MHz main frequency, ARM 920T core

2: ROM: 16Mbit NOR FLASH, 16bit width

3: Electronic disk: 512M bit NAND FLASH, 8bit width

4: RAM: 512Mbit SDRAM, 133MHz, 32bit width (composed of two pieces)

5: Power supply: 7-24V wide voltage input, LT1765 high-efficiency DC/DC step-down, standard 12V power supply

6: Network: 10Mbps low-power embedded dedicated Ethernet network chip CS8900A-CQ3, the interface is a standard RJ45 socket, integrated network transformer, safe and reliable

7: Serial port, 3-way serial port , two-way with handshake signal, can be connected to modem or GPRS. COM3 bit 3-wire system and IRDA use the UART2 signal of the CPU. COM3 and IRDA can only use one of them at the same time

8: IRDA: Reserved RPM851A infrared transceiver module, users can install it by themselves, standard Configuration without soldering. Used with COM3***

9: LCD interface: supports CSTN, TFT and other LCDs

10: Camera interface: 30pin socket is reserved to facilitate users to connect digital cameras

11: Audio interface: stereo audio input and output interface, plus one microphone input

12: USB HOST: 2 USB HOST interfaces, USB FULL SPEED. Can be externally connected to HUB expansion.

13: USB DEVICE: 1-way USB DEVICE interface, USB FULL SPEED

14: SD card interface: supports SD/MMC and SDIO devices

15: Bus expansion: Provides external expansion through 96-pin high-reliability European socket, 32*3 arrangement, integrated bus and other signals that may be used. The external bus is isolated through a high-speed bidirectional buffer to ensure system safety.

16: PCMCIA: Reserved PCMCIA chip and PCMCIA socket (on the back of the board), standard configuration without soldering.

17: JTAG interface: ARM standard 20-core JTAG interface

18: RTC clock: S3C2440A is integrated internally, and the RTC battery is provided externally, installed in a socket, and can be replaced

19: Dual clock design: It adopts two modes of active crystal oscillator + passive crystal oscillator design. The user can choose one of them or use two clocks at the same time to facilitate evaluation.

20: The circuit does not use any encryption measures, such as CPLD and other devices, to ensure that users can 100% use it for their projects.
