The HMU16 and HMU17 are high speed, low power CMOS 16-bit x 16-bit multipliers ideal for fast, real time digital signal processing applications. The X and Y operands along with their mode controls (TCX and TCY) have 17-bit input registers. The mode controls independently specify the operands as either two's complement or unsigned magnitude format, thereby allowing mixed mode multiplication operations. Two 16-bit output registers are provided to hold the most and least significant halves of the result (MSP and LSP). For asynchronous output, these registers may be made transparent through the use of the Feedthrough Control (FT). Additional inputs are provided for format adjustment and rounding. The Format Adjust control (FA) allows the user to select either a left shifted 31-bit product or a full 32-bit product, whereas the round control (RND) provides the capability of rounding the most significant portion of the result. The HMU16 has independent clocks (CLKX, CLKY, CLKL, CLKM) associated with each of these registers to maximize throughput and simplify bus interfacing. The HMU17 has only a single clock input (CLK), but makes use of three register enables (ENX, ENY and ENP). The ENX and ENY inputs control the X and Y Input Registers, while ENP controls both the MSP and LSP Output Registers. This configuration facilitates the use of the HMU17 for microprogrammed systems. The two halves of the product may be routed to a single 16-bit three-state output port via a multiplexer, and in addition, the LSP is connected to the Y-input port through a separate three-state buffer.

A 0.1F capacitor between the VCC and GND pins is recommended. GND. The device ground. X-Input Data. These 16 data inputs provide the multiplicand which may be in two's complement or unsigned magnitude format. Y-Input/LSP Output Data. This 16-bit port is used to provide the multiplier which may be in two's complement or unsigned magnitude format. It may also be used for output of the Least Significant Product (LSP). Output Data. This 16-bit port may provide either the MSP (P16-31) or the LSP (P0-15). Two's Complement Control. Input data is interpreted as two's complement when this control is HIGH. A LOW indicates the data is to be interpreted as unsigned magnitude format. Feed through Control. When this control is HIGH, both the MSP and LSP Registers are transparent. When LOW, the registers are latched by their associated clock signals. Format Adjust Control. A full 32-bit product is selected when this control line is HIGH. A LOW on this control line selects a left shifted 31-bit product with the sign bit replicated in the LSP. This control is normally HIGH, except for certain two's complement integer and fractional applications. Round Control. When this control is HIGH, a one is added to the Most Significant Bit (MSB) of the LSP. This position is dependent on the FA control; FA = HIGH indicates RND adds to the 2-15 bit (P15), and FA = LOW indicates RND adds to the 2-16 bit (P14). Output Multiplexer Control. When this control is LOW, the MSP is available for output at the dedicated output port, and the LSP is available at the Y-input/LSP output port. When MSPSEL is HIGH, the LSP is available at both ports and the MSP is not available for output. Y-In/P0-15 Output Port Three-State Control. When OEL is HIGH, the output drivers are in the high impedance state. This state is required for Ydata input. When OEL is LOW, the port is enabled for LSP output. P16-31/P0-15 Output Port Three-State Control. A LOW on this control line enables the output port. When OEP is HIGH, the output drivers are in the high impedance state.

HMU16, HMU17 Functional Description
The HMU16/HMU17 are high speed 16 x 16-bit multipliers designed to perform very fast multiplication of two 16-bit binary numbers. The two 16-bit operands (X and Y) may be independently specified as either two's complement or unsigned magnitude format by the two's complement controls (TCX and TCY). When either of these control lines is LOW, the respective operand is treated as an unsigned 16-bit value; and when it is HIGH, the operand is treated as a signed value represented in two's complement format. The operands along with their respective controls are latched at the rising edge of the associated clock signal. The HMU16 accomplishes this through the use of independent clock inputs for each of the Input Registers (CLKX and CLKY), while the HMU17 utilizes a single clock signal (CLK) along with the X and Y register enable inputs (ENX and ENY). Input controls are also provided for rounding and format adjustment of the 32-bit product. The Round input (RND) is provided to accommodate rounding of the most significant portion of the product by adding one to the Most Significant Bit (MSB) of the LSP Register. The position of the MSB is dependent on the state of the Format Adjust Control (see Pin Descriptions and Multiplier Input/Output Format Tables). The Round input is latched into the RND Register whenever either of the input registers is clocked. The Format Adjust control (FA) allows the product output to be formatted. When the FA control is HIGH, a full 32-bit product is output; and when FA is LOW, a left-shifted 31-bit product is output with the sign bit replicated in bit position 15 of the LSP. The FA control must be HIGH for unsigned magnitude, and mixed mode multiplication operations. It may be LOW for certain two's complement integer and fractional operations only (see Multiplier Input/ Output Formats Table). The HMU16/HMU17 multipliers are equipped with two 16-bit Output Registers (MSP and LSP) which are provided to hold the most and least significant portions of the resultant product respectively. The HMU16 uses independent clocks (CLKM and CLKL) for latching the two output registers, while the HMU17 uses a single clock input (CLK) along with the Product Latch Enable (ENP). The MSP and LSP Registers may also be made transparent for asynchronous output through the use of the Feed through Control (FT). There are two output configurations which may be selected when using the HMU16/HMU17 multipliers. The first configuration allows the simultaneous access of the most and least significant halves of the product. When the MSPSEL input is LOW, the Most Significant Product will be available at the dedicated output port (P16-31/P0-15). The Least Significant Product is simultaneously available at the bidirectional port shared with the Y-inputs (Y0-15/P0-15) through the use of the LSP output enable (OEL). The other output configuration involves multiplexing the MSP and LSP Registers onto the dedicated output port through the use of the MSPSEL control. When the MSPSEL control is LOW, the Most Significant Product will be available at the dedicated output port; and when MSPSEL is HIGH, the Least Significant Product will be available at this port. This configuration allows access of the entire 32-bit product by a 16-bit wide system bus.

Rev. 0 6/20/95 NOTES: 1. "M" represents the maximum pin matrix size. 2. "N" represents the maximum allowable number of pins. Number of pins and location of pins within the matrix is shown on the pinout listing in this data sheet. 3. Dimension "A1" includes the package body and Lid for both cavity-up and cavity-down configurations. This package is cavity down. Dimension "A1" does not include heatsinks or other attached features. 4. Standoffs are required and shall be located on the pin matrix diagonals. The seating plane is defined by the standoffs at dimension "Q1". 5. Dimension "Q1" applies to cavity-down configurations only. 6. All pins shall be on the 0.100 inch grid. 7. Datum C is the plane of pin to package interface for both cavity up and down configurations. 8. Pin diameter includes solder dip or custom finishes. Pin tips shall have a radius or chamfer. 9. Corner shape (chamfer, notch, radius, etc.) may vary from that shown on the drawing. The index corner shall be clearly unique. 10. Dimension "S" is measured with respect to datums A and B. 11. Dimensioning and tolerancing per ANSI Y14.5M-1982. 12. Controlling dimension: INCH.
