CYM1831 - 64K x 32 Static RAM Module

General Description

The CYM1831 is a high-performance 2-Mbit static RAM module organized as 64K words by 32 bits.

Key Features

  • High-density 2-Mbit SRAM module.
  • 32-bit standard footprint supports densities from 16K x 32 through 1M x 32.
  • High-speed CMOS SRAMs.
  • Access time of 15 ns.
  • Low active power.
  • 5.3W (max. ).
  • SMD technology.
  • TTL-compatible inputs and outputs.
  • Low profile.
  • Max. height of 0.50 in.
  • Small PCB footprint.
  • 1.2 sq. in. on an epoxy laminate board with pins. Four chip selects (CS1, CS2, CS3, and CS4) are.

31 CYM1831 64K x 32 Static RAM Module Features • High-density 2-Mbit SRAM module • 32-bit standard footprint supports densities from 16K x 32 through 1M x 32 • High-speed CMOS SRAMs — Access time of 15 ns • Low active power — 5.3W (max.) • SMD technology • TTL-compatible inputs and outputs • Low profile — Max. height of 0.50 in. • Small PCB footprint — 1.2 sq. in. on an epoxy laminate board with pins. Four chip selects (CS1, CS2, CS3, and CS4) are used to independently enable the four bytes. Reading or writing can be executed on individual bytes or any combination of multiple bytes through proper use of selects. Writing to each byte is accomplished when the appropriate Chip Selects (CSN) and Write Enable (WE) inputs are both LOW.
