SMJ320E14

The SMJ320E14 is a 16/32-bit single-chip digital signal processor that is object-code compatible with the SMJ320C10.This allows hardware upgrading without the expense of software re-development.The highl parallel architecture and efficient instruction set provide the speed and flexibility to execute more than 5 million instruction per second (MIPS).

Features of the SMJ320E14 are:(1)200-ns instruction cycle;(2)256-words of on-chip data RAM;(3)4k-words of on-chip program EPROM;(4)EPROM code protection for copyright security;(5)4k-word total external memory at full speed (microprocessor mode);(6)32-bit ALU/accumulator;(7)16 * 16-bit barrel shifter;(8)seven input and seven output external ports;(9)16-bit bidirectional data bus with greater than 40-mbps transfer rate;(10)bit-selectable I/O port (16 pins);(11)serial port with programmable protocols;(12)event manager with capture inputs and compare outputs;(13)four independent timers;(14)military temperature range is -55 to 125;(15)single 5-V supply;(16)15 internal/external interrupts.

The product ratings of the SMJ320E14 can be summarized as:(1):the parameter is supply voltage range,VCC,the rating is -0.3 to 7,the unit is V;(2):the parameter is supply voltage range,VPP,the rating is -0.6 to 14,the unit is V;(3):the parameter is input voltage range,the rating is -0.3 to 14,the unit is V;(4):the parameter is output voltage range,the rating is -0.3 to 7,the unit is V;(5):the parameter is continuous power dissipation,the rating is 0.5,the unit is W;(6):the parameter is minimum free air temperature,the rating is -55,the unit is ;(7):the parameter is maximum operating case temperature,the rating is 125,the unit is ;(8):the parameter is storage temperature,the rating is -55 to 150,the unit is .
