The STK501 includes connectors, jumpers, and hardware allowing full support for the new features on ATmega103, ATmega64, and ATmega128. The Zero Insertion Force (ZIF) socket allows easy use of TQFP packages. In addition to providing support for new devices, the STK501 also adds support for peripherals previously not supported by the STK500. An additional RS-232 driver and an XRAM interface are among the new features. Devices with dual UART or XRAM interface can thus take advantage of the new res

. Description The ATR4262M1 is a single-chip AM/FM and weather band tuner dedicated for digital IF solutions in car-radio applications. ATR4262M1 is produced using Atmel®’s advanced BICMOS2S technology and fulfills the automotive requirements. This part is suitable for HD Radio™ reception as well as for DRM solutions. The high flexibility allows to design high performance and cost optimized tuner solutions. Broadcast Radio Front-end IC for AM/FM/DRM/HD Radio NOTE: This is a summary document. The

Description The ATA5283 is a 125 kHz ultra-low power receiver used for the wake-up function of Tire Pressure Monitoring (TPM) application. The sensitive input stage of the IC amplifies and demodulates the carrier signal from the antenna coil to a digital output signal for a microcontroller. During the standby mode the preamble detection unit monitors the incoming signal and activates the wake-up output and the data output, if the IC receives a proper 125 kHz carrier signal. By combining the IC w

The system stack of Eureka-147-based digital radio (which includes DAB, DAB+, and T-DMB) provides the flexibility to implement a wide variety of services while providing a platform for the development of future services. Atmel has over 30 year’s experience designing digital radio solutions and offers a complete DAB solution including an RF front end and a DAB decoding baseband. The ATR2740 DAB baseband processor is a highly functional system-on-chip solution. Its flexibility enables the implemen

A MOSFET turns the backlight LEDs on/off and a 4.7ohm resistor limits the maximum current through the LEDs. This makes it quite easy to control the backlight with a PWM signal to adjust intensity. 8297A-AVR-04/10 The SPI interface The Display Xplained module uses a simple SPI interface to communicate with the LCD module. This consist of a Chip-Select (CS) line, a clock line (SCL), and two data lines (SDI/SDO). The SPI is operated in mode 3, i.e. inactive clock is ‘high’, and data is latched on r
