SIGNAL DEFINITIONS

Power

VCC and GND

+5 V power supply. All pins must be

connected.

Clock

CLK — Master Clock

When operating in a synchronous

mode, the rising edge of CLK strobes

all enabled registers. CLK has no

effect when operating in an asynchro-

nous mode.

Inputs

PIN9-0 — Pixel Data Input

PIN9-0 provides address information

to the memory array in Histogram,

Bin Accumulate, and Look Up Table

Modes. Data is latched on the rising

edge of CLK.

DIN23-0 — Data Input

In Bin Accumulate Mode, DIN23-0

provides data to the internal summer

to be added to data already in the

memory array. In Look Up Table

Mode, DIN23-0 is used to load the

memory array with the desired

values. In Delay Memory Mode, the

data to be delayed is input to the

memory array using DIN23-0, and in

Delay and Subtract Mode it also

provides data to be subtracted from

the delayed data. In all four modes,

DIN23-0 is latched on the rising edge

of CLK.

IOA9-0 — Asynchronous Address Input

IOA9-0 provides address information

to the memory array in Asynchronous

16 and 24 Modes.

FCT2-0 — Function Input

FCT2-0 is used to put the LF48410 into

one of its eight modes of operation

(Table 1). Data is latched on the

rising edge of LD. To ensure proper

operation of the device, START must

be HIGH while changing modes, and

there must be at least one rising edge

of CLK between the rising edge of LD

and the falling edge of START.

Inputs/Outputs

DIO23-0 — Data Input/Output

In all synchronous modes, DIO23-0 is

the 24-bit registered data output port.

In all asynchronous modes, DIO23-0 is

both the data input and data output

port for the memory array.

Controls

START — Device Enable

START is used to enable and disable

the synchronous modes of operation

(except for the Delay Memory and

Delay and Subtract Modes). The

synchronous mode sections explain

how START functions in each mode.

START has no effect in asynchronous

modes. Data is latched on the rising

edge of CLK. START must be held

HIGH when changing from one mode

to another. To ensure proper opera-

tion of the device, there must be at

least one rising edge of CLK between

the rising edge of LD and the falling

edge of START.

RD — Read/Output Enable

In all synchronous modes, RD is used

as an output enable for DIO23-0.

When RD is LOW, DIO23-0 is enabled

for output. When RD is HIGH, DIO23-0

is placed in a high-impedance state.

In all asynchronous modes, RD is

used as a read enable for the memory

array (see asynchronous mode

sections for details).

WR — Write Enable

In all asynchronous modes, WR is

used as a write enable for the

memory array (see asynchronous

mode sections for details). WR has

no effect in the synchronous modes.

UWS — Upper Word Select

UWS is only used in Asynchronous 16

Mode. If UWS is LOW and a memory

write is performed, data on DIO15-0 is

written to the lower 16 bits of the

addressed 24-bit word. If UWS is

LOW and a memory read is per-

formed, the lower 16 bits of the

addressed 24-bit word will be output

on DIO15-0. If UWS is HIGH and a

memory write is performed, data on

DIO7-0 is written to the upper 8 bits of

the addressed 24-bit word. If UWS is

HIGH and a memory read is per-

formed, the upper 8 bits of the

addressed 24-bit word will be output

on DIO7-0.

FC — Flash Clear

When FC is LOW, all memory array

locations and data path registers are

set to “0”. To ensure that Flash Clear

functions properly, FC should not be

set LOW until START is HIGH

(synchronous modes) or WR is HIGH

(asynchronous modes).

LD — Function Load Strobe

Data present on FCT2-0 is latched into

the LF48410 on the rising edge of LD.

To ensure proper operation of the

device, there must be at least one

rising edge of CLK between the rising

edge of LD and the falling edge of

START.
