Socket Edition

With Teensy++ 2.0 installed

Board Info

NORwegian Teensy Socket Edition

  • TSOP48 ZIF Socket for NANDs
  • TSOP56 ZIF Socket for NORs
  • 2x 0.1uF decoupling capacitors for each socket (4 in total)
  • 4.7k Ohm Resistor for WP (NOR Socket)
  • Support for either pin headers or a screw terminal block for external power

Requires:

  • Teensy++ 2.0
  • External 3.3V DC Power Supply

Powering the NORwegian Teensy Socket Edition

The 5V pin on the Teensy++ 2.0 is not connected to anything on the Socket Edition, so the Teensy++ 2.0 has to be powered over USB. In order to do this the 5v line needs to be cut on the bottom of the Teensy++ 2.0. Then a MCP1825 voltage regulator needs to be soldered to the Teensy++ 2.0 and the 3.3v pad bridged.

NANDs

When reading and writing to NANDs sometimes an external 3.3V DC power supply isn’t necessary.

NORs

An external 3.3V DC power supply is usually required for reading and writing NORs.

Detailed Board Info

NOR uses this pinout

Exception being that there is a 0.1uF capacitor connected to pins 29+33 and 43+52.

NAND uses this pinout for NANDway SBE (Signal Booster Edition).

However there is no actual “signal boosting” on this board , there is only one connection each for WE, ALE, CLE, and RE. The signals don’t really need to be boosted when there is such a short direct connection between the Teensy++ 2.0 and the NAND. 0.1uF capacitors connected to pins 12+13 and 36+37.
