rca 1802 การใช้

• The spacecraft was controlled by six RCA 1802 COSMAC microprocessor radiation-and static-hardened material ideal for spacecraft operation.
• The IPS ( Interpreter for Process Structures ) programming language was specifically written for the RCA 1802 AMSAT Phase III satellite.
• The Wide Field and Planetary Camera ( WFPC ) also utilized an RCA 1802 microprocessor ( or possibly the older 1801 version ).
• At least one of the on-board experiments, the Thermal Control Surfaces Experiment ( TCSE ), used the RCA 1802 microprocessor.
• The RCA 1802 had what is called a static design, meaning that the clock frequency could be made arbitrarily low, even to 0 Hz, a total stop condition.
• The "'COMX-35 "'was a home computer that was one of the very few systems to use the RCA 1802 microprocessor, the same microprocessor that is also used in some space probes.
• It has been erroneously reported on the Internet that the Voyager space probes were controlled by a version of the RCA 1802 ( RCA CDP1802 " COSMAC " microprocessor ), but such claims are not supported by the primary design documents.
• On the RCA 1802 series of microprocessors, the SEX, for " SEt X, " instruction is used to designate which of the machine's sixteen 16-bit registers is to be the X ( index ) register.
• Other circuits  most prominently, the RCA 1802, but also several later chips such as the WDC 65C02, the Intel 80C85, the Freescale 68HC11 and some other CMOS chips  use " fully static logic " that has no minimum clock rate, but can " stop the clock " and hold their state indefinitely.
