Описание микросхем флеш памяти Atmel: 4-megabit, 2.5-volt or 2.7-volt DataFlash® AT45DB041D
The AT45DB041D is a 2.5V or 2.7V, serial-interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications.
The AT45DB041D supports RapidS serial interface for applications requiring very high speed operations. RapidS serial interface is SPI compatible for frequencies up to 66 MHz. Its 4,325,376 bits of memory are organized as 2,048 pages of 256 bytes or 264 bytes each. In addition to the main memory, the AT45DB041D also contains two SRAM buffers of 256/264 bytes each. The buffers allow the receiving of data while a
page in the main Memory is being reprogrammed, as well as writing a continuous data stream. EEPROM emulation (bit or byte alterability) is easily handled with a self-contained three step read-modify-write operation. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a RapidS serial interface to sequentially access its data. The simple
sequential access dramatically reduces active pin count, facilitates hardware layout,increases system reliability, minimizes switching noise, and reduces package size. The device is optimized for use in many commercial and industrial applications where high-density, low-pin count, low-voltage and low-power are essential.
To allow for simple in-system reprogrammability, the AT45DB041D does not require high input voltages for programming. The device operates from a single power supply, 2.5V to 3.6V or 2.7V to 3.6V, for both the program and read operations. The AT45DB041D is enabled through the chip select pin (CS) and accessed via a three-wire interface consisting of the Serial Input (SI),Serial Output (SO), and the Serial Clock (SCK).
All programming and erase cycles are self-timed.

Ultrasonic ranging module : HC-SR04
power supply :5V DC
quiescent current : <2mA
effectual angle: <15°
ranging distance : 2cm – 500 cm
resolution : 0.3 cm
A short ultrasonic pulse is transmitted at the time 0, reflected by an object. The senor receives this signal and converts it to an electric signal. The next pulse can be transmitted when the echo is faded away. This time period is called cycle period. The recommend cycle period should be no less than 50ms. If a 10?s width trigger pulse is sent to the signal pin, the Ultrasonic module will output eight 40kHz ultrasonic signal and detect the echo back. The measured distance is proportional to the echo pulse width and can be calculated by the formula above. If no obstacle is detected, the output pin will give a 38ms high level signal.
