Pin Descriptions
NAME
TYPE
DESCRIPTION
V
CC
The +5V power supply pins. 0.1
μ
F capacitors between the V
CC
and GND pins are recommended.
GND
The device ground.
X0-X15
I
X-Input Data. These 16 data inputs provide the multiplicand which may be in two's complement or
unsigned magnitude format.
Y0-Y15/P0-P15
I/O
Y-Input/LSP Output Data. This 16-bit port is used to provide the multiplier which may be in two's com-
plement or unsigned magnitude format. It may also be used for output of the least significant product
(P0-P15) or for preloading the LSP Register.
P16-P3
I/O
MSP Output Data. This 16-bit port is used to provide the most significant product output (P16-P31).
It may also be used to preload the MSP Register.
P32-P34
I/O
XTP Output Data. This 3-bit port is used to provide the extended product output (P32-P34). It may
also be used to preload the XTP Register.
TC
I
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. This control is latched
on the rising edge of CLKX or CLKY.
ACC
I
Accumulate Control. When this control is HIGH, the Accumulator Output Register contents are added
to or subtracted from the current product, and the result is stored back into the Accumulator Output
Register.
When LOW, the product is loaded into the Accumulator Output Register overwriting the current con-
tents. This control is also latched on the rising edge of CLKX or CLKY.
