Motorola Minitor. Front view of the Minitor V pager. The Motorola Minitor is a portable, analog, receive only, voice pager typically carried by fire, rescue, and EMS personnel (both volunteer and career) to alert of emergencies. The Minitor, slightly smaller than a pack of cigarettes, is carried on a person and usually left in selective call mode.
The 68HC11 [1] (also abbreviated as 6811 or HC11) is an 8-bit microcontroller family introduced by Motorola Semiconductor in 1984 (later from Freescale then NXP ). [2] [3] It descended from the Motorola 6800 microprocessor by way of the 6801. The 68HC11 devices are more powerful and more expensive than the 68HC08 microcontrollers and are used ...
Motorola's 1987 Application Node AN991 "Using the Serial Peripheral Interface to Communicate Between Multiple Microcomputers" (now under NXP, last revised 2002) informally serves as the "official" defining document for SPI. Timing variations. Some devices have timing variations from Motorola's CPOL/CPHA modes.
Motorola 68HC05. The 68HC05 (also abbreviated as HC05) is a broad family of 8-bit microcontrollers from Motorola Semiconductor (later from Freescale then NXP ). Like all Motorola processors that share lineage from the 6800, they use the von Neumann architecture as well as memory-mapped I/O. This family has five CPU registers that are not part ...
Selective calling. In a conventional, analog two-way radio system, a standard radio has noise squelch or carrier squelch, which allows a radio to receive all transmissions. Selective calling is used to address a subset of all two-way radios on a single radio frequency channel. Where more than one user is on the same channel (co-channel users ...
The most common set of supported tones is a set of 39 tones including all tones with Motorola PL codes, except for the tones 8Z, 9Z, and 0Z (zero-Z). The lowest series has adjacent tones that are roughly in the harmonic ratio of 2 0.05 to 1 (≈1.035265), while the other two series have adjacent tones roughly in the ratio of 10 0.015 to 1 (≈1 ...
Motorola 68HC08. The 68HC08 (also abbreviated as HC08) is a broad family of 8-bit microcontrollers from Motorola Semiconductor (later from Freescale then NXP ). HC08's are fully code-compatible with their predecessors, the Motorola 68HC05. Like all Motorola processors that share lineage from the 6800, they use the von Neumann architecture as ...
PowerPC, Motorola ColdFire. A Motorola 68EC060 microprocessor. The Motorola 68060 (" sixty-eight-oh-sixty ") is a 32-bit microprocessor from Motorola released in April 1994. [3] It is the successor to the Motorola 68040 and is the highest performing member of the 68000 series. Two derivatives were produced, the 68LC060 and the 68EC060 .
