These are new OS parts , and come in a 44 pin TQFP surface mount package as pictured. They are industrial temperature range units capable of operation from (-40°C to 85°C). The operational voltage of this particular version is 2.7V to 6.0V which makes them suitable for small battery powered applications. These require a 4mhz crystal or resonator and have a throughput of 4 MIPs at that speed. ( thats the same as most PICs at 16 MHZ) The AT90S4414 production was discontinued in 2000 but it is still quite powerful and can be used successfully for many applications for the hobbyist or experimenter. These are essentially the same as the AT90S8515 except with half the memory These units are also pin compatible with the Mega161 and Mega8515 except with less features The AT90S4414 is a low-power CMOS 8-bit micro controller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AT90S4414 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. • AVR® - High Performance and Low Power RISC Architecture • 118 Powerful Instructions - Most Single Clock Cycle Execution • 4K bytes of In-System Re programmable Flash SPI Serial Interface for Program Downloading Endurance: 1,000 Write/Erase Cycles • 256 bytes EEPROM • 32 x 8 General Purpose Working Registers Endurance: 100,000 Write/Erase Cycles • 256 bytes Internal SRAM • 32 Programmable I/O Lines • Programmable Serial UART • VCC: 2.7 - 6.0V • SPI Serial Interface 0 - 4 MHz, 2.7 - 4.0V • Up to 4 MIPS Throughput at 4 MHz • One 8-Bit Timer/Counter with Separate Prescaler • Dual PWM • One 16-Bit Timer/Counter with Separate Prescaler • External and Internal Interrupt Sources • Programmable Watchdog Timer with On-Chip Oscillator • Low Power Idle and Power Down Modes • On-Chip Analog Comparator • Programming Lock for Software Security (this posting is the responsibility of the poster) |
