DESCRIPTION
The M66307SP/FP is an integrated circuit consisting of a line buffer
with static memory, manufactured by the silicon gate CMOS pro-
cess, which satisfies A3-paper 400DPI requirements. It converts the
stored data from the 16-bit MPU bus into serial data and outputs it at
a transfer rate of up to 10Mbps synchronously with the external data
request clock or an arbitrary continuous clock.
FEATURES
• ^{16-bit MPU bus compatible}
• ^{Writing data via DMAC is possible}
• ^{320-word (5,120-bit) static RAM}
• ^{Data output rate of up to 10Mbps}
• ^{Built-in function to add fixed data of a specified length at the be-}
ginning of output data (Fixed data: Continuous High bit or Low bit
data)
• ^{The output format can be selected between FIFO or LIFO.}
• ^{The output method can be selected from two:}
(1) Synchronized with an arbitrary continuous clock (φ IN) on the
system side; the frequency of clock output (CLK/φ OUT) can
be divided by 1, 2, 4, 8, or 16.
(2) Synchronized with the data request clock (CLK IN) on the pe-
ripheral equipment side.
• ^{Up to two devices can be cascaded.}
(1) Toggle configuration
(2) 32-bit bus configuration
• ^{High fan-out outputs (CLK/φ OUT, DATA OUT).}
Io = ±24mA
(±4mA for INTR and DREQ
±8mA for BUSY/ORDY)
