The LMA1010 and LMA2010 are high-speed, low power 16-bit multiplier-accumulators. The LMA1010 and LMA2010 are functionally identical; they differ only in packaging. Full military ambient temperature range operation is achieved with advanced CMOS technology. TC ACC SUB 32 R R + A OEX OEM OEL PRELOAD CONTROL LOGIC The LMA1010/2010 output register (accumulator register) is divided into three independently controlled sections. The least significant result (LSR) and most significant result (MSR) registers are 16 bits in length. The extended result register (XTR) is 3 bits long. The output signals R15-0 and input signals B15-0 share the same bidirectional pins. 3 A R – A PASS R LEX LEM LEL 35 PREL 3 OEX OEM OEL LEX 35 LEM 3 LEL 16 16 ACCUMULATOR REGISTER CLK R OEX 3 R 34-32 OEM OEL 16 16 Each output register has an independent output enable control. In addition to providing three-state control of the output buffers, when OEX, OEM, or OEL are HIGH and PREL is HIGH, data can be preloaded via the bidirectional output pins into the respective output registers. Data present on the output pins is latched on the rising edge of CLK R. The interrelation of PREL and the enable controls is summarized in Table 1.
