Some TTL logic parts were made with an extended military-specification temperature range. These parts are prefixed with 54 instead of 74 in the part number. [1]A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by 1973.
ICP is a Carrier subsidiary. ICP makes oil and gas furnaces, heat pumps, and central air-conditioning systems for residential and commercial customers. [1] It manufacturers, markets, and sells residential heating and cooling systems under the Arcoaire, Comfortmaker, Day & Night, Heil, KeepRite, Lincoln, and Tempstar brands; its commercial units, with up to 25 tons of cooling capacity, are sold ...
Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
While Arm is a fabless semiconductor company (it does not manufacture or sell its own chips), it licenses the ARM architecture family design to a variety of companies. Those companies in turn sell billions of ARM-based chips per year—12 billion ARM-based chips shipped in 2014, [1] about 24 billion ARM-based chips shipped in 2020, [2] some of those are popular chips in their own right.
The instruction set also varies by model, with more powerful chips adding instructions for digital signal processing functions. The hardware implementations of PIC devices range from 6-pin SMD , 8-pin DIP chips up to 144-pin SMD chips, with discrete I/O pins, ADC and DAC modules, and communications ports such as UART , I2C , CAN , and even USB .
ATtiny (also known as TinyAVR) is a subfamily of the popular 8-bit AVR microcontrollers, which typically has fewer features, fewer I/O pins, and less memory than other AVR series chips. The first members of this family were released in 1999 by Atmel (later acquired by Microchip Technology in 2016).
Each chip has a factory-programmed 96-bit unique device identifier number. Peripherals: Common peripherals included in all IC packages are USB 2.0 FS, two SPI, two I²C, three USART, eight 16-bit timers, two watchdog timers, temperature sensor, 16 to 24 channels into one ADC, two DACs, 37 to 83 GPIOs, seven DMA, real-time clock (RTC), cyclic ...
By reducing the number of flawed chips, from about 70% to 10%, the cost of complex designs like early microprocessors fell by the same amount. Systems based on contact aligners cost on the order of $300 in single-unit quantities, the MOS 6502 , designed specifically to take advantage of these improvements, cost only $25.
