The state diagram of M64285FP is shown above. The sequence to control M64285FP is
explained below.
(1) Reset all the registers and counters.
RESET is set to "L" (asynchronous to CLK). Reset state is in the Standby state.
(2) Set the contents of the registers.
There are 16 sets of registers, consisting of 4 bits each. The input data is composed of 8
bits. The leading 4 bits are for address and the following 4 bits are for data. The input
data is latched at the rising edge of SCLK. When LOAD goes "H", the contents of the
register become fixed at the rising edge of CLK.
(3) Start image capture.
After the contents of all the registers are fixed, START is asserted in synchronous with
the rising edge of CLK. Then the control counters are reset to the initial value specified
by the registers, and the image capture sequence starts. After the accumulation time
defined by the registers 4 ~ 7, the analog image signals are outputted serially. The STRB
pulse is outputted in synchronous with the above. The number of active data on one
frame is 1024 for the 2D image, 64 for the projection image, and 1 for the pixel average
data; the number of data outputted in each modes is fixed by the combination of the
above. When this chip finishes outputting the defined number of data, in the snapshot
modes (MD3=1), it automatically falls into the Standby state. In the continuous modes
(MD3=0), once the image capture sequence starts, this chip carries on outputting the
image data, unless START is asserted again or STOP bit is set to "H" to force the chip
into the Standby state.
The contents of the registers can be changed in the Standby state. When START is asserted
in the standby state or in the continuous image capture sequence, the control counters are,
again, reset to the initial value specified by the registers, and the image capture sequence
starts. If the register contents are changed before asserting START, M64285FP outputs the
data in a different mode. In the continuous output modes, register No. 2 including the STOP
bit is the only register that is allowed to be set.

STOP bit forces the chip into Standby state from the continuous image capture state.
When "STOP = 1" is set, image capture sequence stops and the chip falls into the
Standby state, with preserving the register contents. Afterwards, STOP bit is
automatically reset to "0". This bit is allowed to be set in the continuous output modes.
M64285FP can output the inverted STRB signal. If needed, set STINV to "1", else,
set it to "0". M64285FP outputs the optical black level before outputting the image data.
BSTRB selects whether to output the STRB pulse at the optical black level output
timing. If needed to be ON, set BSTRB to "1", else, set it to "0".
POWSV selects the Power Save state, in which power consumption is suppressed by
reducing the AMP current to be 1/10 while the chip is not outputting the analog data
(ex.: just after RESET, or in the accumulation period). The default state for POWSV is
1 (ON). Besides, if the STDBY bit is 1, power consumption is further suppressed by
completely cutting the AMP current while the chip is in the Standby or Halt state.

2D Image Mode ( MD = 0000 ) : Similar to the ordinary CMOS image sensors, M64285FP
output the 2D (two dimensional) image data projected on the image plane by X-Y address
scanning.
11.3.2. Projection Image Continuous Mode ( MD = 0100 )
Right figure shows the projection operation.
Two dimensional (2D) input image pattern is
illuminating the image plane, and all the pixel
data in each columns and each rows are taken
average followed by 32 column projection data
output and 32 row projection data output in
sequence. It is a kind of Image compression, in
which 1024 bytes output data in the 2D form is
compressed to 64 bytes data. Therefore the
readout time and the processing cost in the
subsequent part is widely reduced. Also, the
data range of projection is the same as the 2D
image data.

11.5. Accumulation Time Setting Register, C (16 bits)
The accumulation time of 2D image is set based on the time step needed to read out one
line. In the Projection image continuous output modes or in snapshot modes, the time step is
32f , however, there are lower limits of the setting time in projection image continuous
output modes decided by the readout time.
Although it is possible to set a very long accumulation time on the register in the order of
second, it does not necessarily mean the analog function is guaranteed.

data before amplification. By means of this function, as shown in the figure, it becomes
possible to obtain high contrast image in the optimum range. OFST register decides the
magnitude of this offset. The output data is obtained after subtracting the value in the table
below from the image data, under the standard gain condition (0 dB). The offset value to be
subtracted is proportional to the gain. If there is no need of subtracting offset, as in the case
of capturing normal image in full range, set the OFST Register 00000.

13. Operational Timing
13.1. Chip Reset • Register Set • Image Capture Start
The registers are set after resetting the chip. The timing chart below shows the operation up
to the image capture. RESET is done asynchronous with CLK. The input data, SIN, which
is used to set registers is inputted serially asynchronous with CLK and latched to the registers
by the LOAD signal. Detailed timing of SIN and LOAD is given in "13.2. Register Set".
After the contents of all registers have been decided, START is inputted in synchronous with
the rise of CLK. Then, the counter used for controlling purposes is reset to the initial value
which is specified by the register. Now, the image capture starts. If the period of LOAD or
START is longer than 2 CLKs, the valid timing is the first CLK rise for LOAD, and the last
CLK rise for START.

13.2. Register Set
The input data SIN is composed of 8 bits (x16). The leading 4 bits are the address and the
following 4 bits are data. The input data is transferred to a temporary register at the rising
edge of SCLK (asynchronous with CLK), and when LOAD goes "H", the contents of the
register become fixed at the rising edge of CLK.

13.3. Image Data Output
Image data is outputted from VOUT serially. Simultaneously, the STRB signal is outputted
as the timing reference for A/D conversion. The STRB is basically in synchronous with the
rising edge of CLK, and its pulse width ("H" level) is 4f . However the pulse width ("H"
level) becomes 2f only when DOC = 4f . At the timing of outputting the optical black pixel
(OBP), STRB pulse is outputted only in the case BSTRB = 1. OBP timing is shown by the
hatched STRB pulse or the hatched box.
