MSM5424331 - Field Memory

Description

The MSM5424331 is an image data processing field memory organized as 222,720 (768 pixels by 290 lines) by 24 bits that can switch between the FIFO mode where the MSM5424331 is used as an ordinary field memory and a block access mode where the MSM5424331 can easily exchange data with personal compute

Features

  • Switching between FIFO and Block Access modes by the D/F pin FIFO mode: Serial write/read operation by line-by-line accessing Block Access mode: Fast write/read operation on an 8-word basis by the RAS and CAS control.
  • Organization of 768 × 290 × 24 bits FIFO mode: Input × 12 or × 24 controlled by L/UWE Output × 24 Block Access mode: Input × 12 (Two 768 × 290 × 12-bit banks are controlled by L/UWE. ) Output × 12 (Two 768 × 290 × 12-bit banks are controlled by A9.).
  • Asyn.

www.DataSheet4U.com FEDS5424331-01 1 Semiconductor MSM5424331 222,720-Word × 24-Bit Field Memory This version: Sep. 2000 GENERAL DESCRIPTION The MSM5424331 is an image data processing field memory organized as 222,720 (768 pixels by 290 lines) by 24 bits that can switch between the FIFO mode where the MSM5424331 is used as an ordinary field memory and a block access mode where the MSM5424331 can easily exchange data with personal computer and the like. Serial writing in and serial reading from the MSM5424331 are performed line by line. In the FIFO mode, any line can be selected by specifying their addresses by the Serial Address input. In the Block Access mode, any line or word address (10 bits) can be set by entering the address through the address multiplexer.
