The ADC and DSP are interfaced together to simultaneously acquire voltage and current samples on all the three phases and perform mathematically intensive computations to accurately calculate the Powers, Energies, Instantaneous Quantities, and Harmonics. The chipset could be interfaced to any general-purpose microprocessor to develop state of the art polyphase or Tri-vector energy metering solution in accordance with IEC 1036, IEC 687, or ANSI C12.1. All calibrations are done in digital domain and no trimming potentiometers are required. SALEM is a registered trademark of Analog Devices, Inc.

Single-Cycle Instruction Execution The ADSST-2185KST-133 combines the ADSP-2100 family Single-Cycle Context Switch base architecture (three computational units, data address Three-Bus Architecture Allows Dual Operand Fetches generators, and a program sequencer) with two serial ports, a in Every Instruction Cycle 16-bit internal DMA port, a byte DMA port, a programmable Multifunction Instructions timer, Flag I/O, extensive interrupt capabilities, and on-chip Power-Down Mode Featuring Low CMOS Standby Power program and data memory. Dissipation with 100 Cycle Recovery from Power-Down Condition The ADSST-2185KST-133 integrates 40 kBytes of on-chip Low Power Dissipation in Idle Mode memory configured as 8 Kwords (24-bit) of program RAM and ADSP-2100 Family Code Compatible, with Instruction 8 Kwords (16-bit) of data RAM. Power-down circuitry is also Set Extensions provided to meet the low power needs of battery operated portable 40 kBytes of On-Chip RAM, Configured as equipment. The ADSST-2185KST-133 is available in a 100-lead 8 KWords On-Chip Program Memory RAM and TQFP package. 8 KWords On-Chip Data Memory RAM In addition, the ADSST-2185KST-133 supports instructions Dual Purpose Program Memory for Both Instruction that include bit manipulations, bit set, bit clear, bit toggle, bit and Data Storage test new ALU constants, new multiplication instruction (x squared), Independent ALU, Multiplier/Accumulator, and Barrel biased rounding, result free ALU operations, I/O memory transShifter Computational Units fers, and global interrupt masking for increased flexibility. Two Independent Data Address Generators Powerful Program Sequencer Provides Zero Overhead Fabricated in a high speed, double metal, low power, CMOS Looping Conditional Instruction Execution process, the ADSST-2185KST-133 operates with a 25 ns Programmable 16-Bit Interval Timer with Prescaler instruction cycle time. Every instruction can execute in a single 100-Lead TQFP processor cycle. 16-Bit Internal DMA Port for High Speed Access to OnThe ADSST-2185KST-133’s flexible architecture and comet4U.com Chip Memory (Mode Selectable) prehensive instruction set allow the processor to perform 4 MBytes Byte Memory Interface for Storage of Data multiple operations in parallel. In one proces.
