This document introduces the features and characteristics of the Atmel ATmega328P-AU 8-bit microcontroller

AT8xC5111 is a high-performance ROM/OTP version of the 80C51 8-bit microcontroller in low pin count package.

The AT75C221 is a high-performance intelligent network appliance processor for professional network appliance applications such as the Ethernet IP phone. The processor is based on an ARM7TDMI microcontroller core running at 40 MHz with an OakDSPCore coprocessor running at 60 MHz and a dual Ethernet 10/100 Mbit/s MAC interface.

The U211B is an integrated circuit designed as a phase-control circuit in bipolar technology with an internal frequency-voltage converter. It also has an internal control amplifier, making it suitable for speed-regulated motor applications. It features integrated load limitation, tacho monitoring, soft-start functions, etc. to enable sophisticated motor control systems.

B10011S is a CAN bus system transceiver with high output voltage. It is designed for point-to-point interface between truck and trailer according ISO WD 11992-1

The document describes the features and characteristics of the ATF16V8B high-performance CMOS programmable logic device, including industry-standard architecture, high-speed electrically erasable programmable logic devices, several power-saving options, CMOS and TTL compatible inputs and outputs, advanced Flash technology, high reliability CMOS process, etc.

This high-density, high-performance electrically-erasable complex programmable logic device has a 3.0 to 3.6V operating range, 32 macrocells, 5 product terms per macrocell, expandable up to 40 per macrocell, 44 pins, 15 ns maximum pin-to-pin delay, registered operation up to 77 MHz, and enhanced routing resources.

The AT49F010/HF010 1-Megabit (128K x 8) 5-volt Only CMOS Flash Memory is an in-system programmable and erasable Flash Memory manufactured by Atmel. Their 1-megabit of memory is organized as 131,072 words by 8 bits. Manufactured with Atmel's advanced nonvolatile CMOS technology, the devices offer access times to 45 ns (HF version) with a power dissipation of just 165 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 100 µA. To allow for simple in-system reprogrammability, the AT49F010/HF010 does not require high input voltages for programming. Five-volt-only commands determine the read and programming operation of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT49F010/HF010 is performed by erasing the entire 1 megabit of memory and then programming on a byte by byte basis.

The AT49F004(T) and AT49F4096A(T) are 5-volt, 4-megabit Flash Memories orga- nized as 524,288 words of 8 bits each or 256K words of 16 bits each. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 55 ns with power dissipation of just 275 mW. When deselected, the CMOS standby current is less than 300 µA. The device contains a user-enabled “boot block” protection feature. Two versions of the feature are available: the AT49F004/4096A locates the boot block at lowest order addresses (“bottom boot”); the AT49F004T/4096AT locates it at highest order addresses (“top boot”). To allow for simple in-system reprogrammability, the AT49F004(T)/4096A(T) does not require high input voltages for programming. Reading data out of the device is similar to reading from an EPROM; it has standard CE, OE, and WE inputs to avoid bus con- tention. Reprogramming the AT49F004(T)/4096A(T) only requires one pin, CE. For most operations, the other pins are in high-impedance state.

The AT34C02B is a serial electrically-erasable and programmable read only memory (EEPROM) with 256 x 8 bits organization. It features permanent and reversible software write protection for the first-half of the array, hardware write protection for the entire array, low-voltage and standard-voltage operation, two-wire serial interface, bidirectional data transfer protocol, and compatibility with different clock speeds. It also has high-reliability with endurance of 1 million write cycles and data retention of 100 years. The package options include JEDEC SOIC, Ultra Thin Mini-MAP (MLP 2x3), TSSOP, and dBGA2.

The T0782 is a high-linearity active mixer which is manufactured using Atmel’s advanced Silicon-Germanium technology. This mixer features a frequency range of 2200 MHz to 2700 MHz. It operates from a single 5-V supply and provides 10 dB of conversion gain while requiring only 0 dBm input to the integrated LO driver. An IF amplifier is also included. The T0782 incorporates internal matching on each RF, IF and LO port to enhance ease of use and to reduce the external components required. The RF and LO inputs can be driven differentially or single-ended.

The U209B is a phase-control integrated circuit designed for motor speed control with tacho feedback. It features an internal frequency-to-voltage converter, externally controlled integrated amplifier, automatic soft start, voltage and current synchronization, retriggering, and more.

The U2008B is a phase-control circuit designed in bipolar technology. It features load-current detection and mains-compensated phase control. Preferred applications include motor control with load-current feedback and overload protection. The features include full wave current sensing, mains supply variation compensation, variable soft-start or load-current sensing, voltage and current synchronization, automatic retriggering switchable, triggering pulse typ. 125 mA, internal supply-voltage monitoring, and a current requirement of 3 mA.

U2010B is a bipolar technology phase-control circuit that enables load-current detection, has a soft-start function as well as reference voltage output. Preferred applications are motor control with load-current feedback and overload protection.
