AT28HC256 is a high-performance Electrically Erasable and Programmable Read Only Memory with features including fast read access time, automatic page write operation, fast write cycle times, low power dissipation, hardware and software data protection, DATA polling, etc.

The U2043B is used in relay-controlled automotive flashers where a high EMC level is required. A lamp outage is indicated by frequency doubling during hazard mode as well as direction mode. The pilot lamp can be connected either to VBatt or GND.

The U2044B is an integrated circuit used in relay-controlled automotive flashers. With two output stages, each side of the vehicle is controlled separately. It has a left and a right direction indicator input with only a small control current, making switch contacts for small loads possible. The separate hazard warning input simplifies the construction of the hazard switch. Lamp outage is indicated by frequency doubling during direction mode. Thanks to the extreme low current consumption, the U2044B can be connected to the battery directly.

TS80C31X2 is a high-performance CMOS and ROMless version of the 80C51 CMOS single-chip 8-bit microcontroller.

The TK5561A-PP is a complete transponder integrating all important functions for immobilizer and identification systems. It consists of a plastic cube which accommo- dates the crypto IDIC e5561A and the antenna realized as tuned LC-circuit. The TK5561A-PP is a R/W crypto transponder for applications which demand higher secu- rity levels than those which standard R/W transponders can fulfil.

The TK5552 is a complete programmable R/W transponder which implements all important functions for identification systems.

The TK5552 is a complete programmable R/W transponder that implements all important functions for identification systems. It allows the contactless reading and writing of data which are transmitted bi-directionally between a read/write base station and the transponder.

The TK5530 is a complete transponder used for car immobilization, access control, alarm systems, and other identification systems. It consists of a plastic cube with an e5530 IDIC chip and a tuned circuit antenna. The e5530 chip stores 128 bits of read-only data, which is transmitted to the base station via an RF field. The product has anti-counterfeiting features.

The TK5530 is a complete transponder for immobilizer and identification systems. It consists of a plastic cube housing the e5530 IDIC chip and a tuned LC-circuit antenna. It operates at a carrier frequency of 125 kHz and stores identifying data in a 128-bit PROM. It immediately detects any attempt to fake the base station.

High density, high performance electrically erasable complex programmable logic device, 32 macrocells, 5 product terms per macrocell, expandable up to 40 per macrocell, 44 pins, 7.5 ns maximum pin-to-pin delay, registered operation up to 125 MHz, enhanced routing resources

This file is a detailed introduction to the 6507BS chip produced by Atmel. The chip adopts the AVR Enhanced RISC Architecture architecture and has the characteristics of high performance and low power consumption. The chip has 320K Bytes of ROM Program Memory, 288K Bytes of EEPROM, 8K Bytes of RAM, and two I/O ports, ISO7816 controller, serial peripheral interface, programmable internal oscillator, two 16-bit timers, random number generator, two-level 8-way interrupt controller, 32-bit cryptographic accelerator, hardware DES and triple DES.

The AT88SC1003 is a low-cost synchronous integrated circuit designed for use in prepaid and loyalty smart card applications. The AT88SC1003 provides 1024 bits of serial EEPROM (Electrically Erasable and Programmable Read Only Memory) within three application zones, plus 64 bits in a code-protected zone. Security logic provides access protection through use of a 16-bit security code. Additional EEPROM memory is available to hold unalterable information about the card history. Separate zones are available for data written by the fabrication facility, card manufacturer and card issuer. After personalization of the memory by the issuer, an internal fuse is blown that secures critical data.

This document describes a 4 megabit (512K x 8) 5-volt CMOS flash memory with features such as single voltage operation, fast read access time, internal program control and timer.

AT49BV512 is a 3-volt-only, 512K Flash memories organized as 65,536 words of 8 bits each. Manufactured with Atmel's advanced nonvolatile CMOS technology, the devices offer access times to 120 ns with power dissipation of just 90 mW over the commercial temperature range. When the devices are deselected, the CMOS standby current is less than 50 µµµµA. To allow for simple in-system reprogrammability, the AT49BV512 does not require high input voltages for programming. Three-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 AT49BV512 is performed by erasing the entire 1 megabit of memory and then programming on a byte by byte basis.
