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 am building a memory module for an 8-bit computer, and am running into an issue. The chip is receiving 5V, which is within the 61116 listed on the datasheet. I have connected the outputs to 8 LEDs and tied all address inputs low.

At first everything works as expected. I can view each byte of junk data the SRAM has been initialized with. After a while in this state the chip will begin to heat up and then all sramm the outputs switch to low, regardless of their previous state and without any intervention on my part. 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.

I have observed this behavior with all 3 IDT chips I ordered. So typically the output voltage of the IDT could be higher.

An LED’s IV curve is exponential, so if you give srm a little more voltage, you get a lot more current. So I believe what is happening here is the IDT part is sourcing much more current and burning up much more power. 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 away.

Following this schematic, but using an IDT instead of the AS6C shown The chip is receiving 5V, which is within the tolerances listed on the datasheet. Eli Lorden 12 2. What speed grade 61116 your RAM chips, and where did you get them? What value is the LED current-limiting resistor? Better still, use another buffer to drive the LEDs.
