Creltek SDRAM TSOP-45 Adapter

Creltek SDRAM TSOP-45 Adapter provides access to TSOP-54 DRAM ICs in a 0.8" wide DIP-54 form factor. It is available as a bare board with pin/socket strips included, or completely assembled with one of two 32 Megabyte (16Mx16) 3.3V SDRAMs: ISSI IS42S16160G-7TL (4M x 16bit x 4Banks SDRAM, 3.3V, 143MHz) or Micron/Alliance Memory MT48LC16M16A2TG-6A:G (4M x 16bit x 4Banks SDRAM, 3.3V, 167MHz).

Why did you make it?

I needed to interface an SDRAM IC to one of my microcontroller projects. This adapter can be plugged directly into a solderless breadboard or 0.8" wide DIP socket. Creltek-exclusive "combo" through-board pin/socket strips feature machined three-finger sockets on the top side of the board, with machined pins on the bottom side that extend the same length as standard DIP IC leads. This allows you to easily probe or attach jumper wires even when the board is plugged to a socket in-circuit.

Features

• On-board power supply decoupling capacitors
• All 54 pins are brought out in the same arrangement as the SDRAM IC
• All Vss pins are internally connected to a common ground plane
• All Vdd and Vddq pins are internally connected to a common Vdd bus
• Compatible with standard TSOP-54 pinouts for 4-, 8-, and 16-bit wide SDRAMs
• Sensible layout and routing optimized for low noise
