A chip scale atomic clock (CSAC) is a compact, low-power atomic clock fabricated using techniques of microelectromechanical systems (MEMS) and incorporating a low-power semiconductor laser as the light source. The first CSAC physics package was demonstrated at the National Institute of Standards and Technology in 2003, [1] based on an invention ...
Toshiba TLCS-12, a microprocessor developed for the Ford EEC (Electronic Engine Control) system in 1973. [11] Intel 8080 CPU launched in 1974 was manufactured using this process. [96] The Television Interface Adaptor, the custom graphics and audio chip developed for the Atari 2600 in 1977. [97]

Bare silicon chip, an early chip-scale package CSP: Chip-scale package: Package size is no more than 1.2× the size of the silicon chip [16] [17] TCSP: True chip-size package: Package is same size as silicon [18] TDSP: True die-size package: Same as TCSP [18] WCSP or WL-CSP or WLCSP: Wafer-level chip-scale package
An atomic battery, nuclear battery, radioisotope battery or radioisotope generator uses energy from the decay of a radioactive isotope to generate electricity. Like a nuclear reactor , it generates electricity from nuclear energy, but it differs by not using a chain reaction .
Since only a few packages are chip size, the meaning of the acronym was adapted to chip-scale packaging. According to IPC 's standard J-STD-012, Implementation of Flip Chip and Chip Scale Technology , in order to qualify as chip scale, the package must have an area no greater than 1.2 times that of the die and it must be a single-die, direct ...
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
For practical devices, this decrease occurs over a period of many years. For tritium devices, the half-life is 12.32 years. In device design, one must account for what battery characteristics are required at end-of-life, and ensure that the beginning-of-life properties take into account the desired usable lifetime.
