General Description

The EM482M3244VTA is Synchronous Dynamic Random Access Memory ( SDRAM ) organized as 524,288 words x 4 banks x 32 bits.

All inputs and outputs are synchronized with the positive edge of the clock .

The 64Mb SDRAM uses synchronized pipelined architecture to achieve high speed data transfer rates and is designed to operate in 3.3V low power memory system.

Key Features

  • Fully synchronous to positive clock edge.
  • Single 3.3V +/- 0.3V power supply.
  • LVTTL compatible with multiplexed address.
  • Programmable Burst Length ( B/ L ) - 1,2,4,8 or full page.
  • Programmable CAS Latency ( C/ L ) - 2 or 3.
  • Data Mask ( DQM ) for Read/Write masking.
  • Programmable wrap sequential - Sequential ( B/ L = 1/2/4/8/full page ) - Interleave ( B/ L = 1/2/4/8 ).
  • Burst read with single-bit write operation.
  • All i.
