DESCRIPTION

The M66307SP/FP is an integrated circuit consisting of a line buffer with static memory, manufactured by the silicon gate CMOS process, 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 beginning 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 peripheral 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)

• The clock input (CLK/φ IN) contains a Schmitt trigger.

• The reset (RESET), Write (WR) and toggle input (TOG) contain negative noise reduction circuits.

APPLICATION

Image-handling general OA equipment
