6116 SRAM PDF

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. Sign up or log in Sign up using Google. And be sure to use a separate resistor for each LED.

I am building a memory module for an 8-bit computer, and am running into an issue. After a while in this 61116 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.

What value is the LED current-limiting resistor? I have connected the outputs to 8 LEDs and tied all address inputs low.

Increase the current limit the LED’s or remove them, yeah its cool to see the data go by sraam useless and the problem in all likelihood will go away. The chip is receiving 5V, which is within the tolerances listed on the datasheet.

Post as a guest Name. An LED’s IV curve srm exponential, so if you give it a little more voltage, you get a lot more current. Email Required, but never shown. So I believe what is happening here is the IDT part is sourcing much more current and burning up much more power.

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. I have observed this behavior with all 3 IDT chips I ordered. What speed grade are your RAM chips, and where did you get them? 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.
