The IDTSA/LA is a 16,bit high-speed static RAM organized The IDTSA/LA is packaged in pin mil plastic DIP, pin. The 5V CMOS SRAM is organized as 2K x 8. The offers a reduced power standby low-power (LA) version also offers a battery backup data. The IDTSA/LA is a 16,bit high-speed static RAM organized as 2K x 8. It is fabricated using IDT’s high-perfor- mance, high-reliability CMOS technology.

I can view each byte of junk data the SRAM has been initialized with. Eli Lorden 12 2. I have observed this behavior with all 3 IDT chips I ordered. So I believe what is happening here is the IDT part is sourcing much more current and burning up much more power.

Better still, use another buffer to drive the LEDs. What value is the LED current-limiting resistor?
An LED’s IV curve is exponential, so if you give it a little more voltage, you get a lot more current. Sign up using Email and Password. What speed grade are your RAM chips, and where did you get them? Sign up or log in Sign up using Google.
The SRAM chip does not appear to be damaged by this, as when power is cycled off and back on again it returns to working normally. Home Questions Tags Users Unanswered. Increase the current limit the LED’s or remove them, yeah its cool to see the data go by but useless and the problem in all likelihood will go sgam. After a while in this state the chip will begin to heat up and then all of the outputs switch to low, regardless of their previous state and without any intervention on my part.

So typically the output voltage of the IDT could be higher. I have connected the outputs to 8 LEDs and tied all address inputs low.
