LMA1010 - 16 x 16-bit Multiplier-Accumulator

Datasheet Summary

Description

TC, ACC, and SUB controls are latched on the rising edge of the logical OR of CLK A and CLK B.

TC specifies the input as two’s complement (TC HIGH) or unsigned magnitude (TC LOW).

RND, when HIGH, adds ‘1’ to the most significant bit position of the least significant half of the product.

Features

  • u 20 ns Multiply-Accumulate Time u Replaces Fairchild TMC2210, Cypress CY7C510, IDT 7210L, and AMD Am29510 u Two’s Complement or Unsigned Operands u Accumulator Performs Preload, Accumulate, and Subtract u Three-State Outputs u 68-pin PLCC, J-Lead LMA1010/2010 BLOCK.
