Choosing IC with EN signal 1. Part and Inventory Search. I’m beginning to suspect on my memory chip. In this case, the wiring may be a problem, particularly insufficient or too long ground connection between both boards.


Tonight I will write a small program which hm622566 read and verify the memory and report failure if any, and leave it over night. PNP transistor not working datasheer. After a bit of searching, find that also Mosel-Vitelic MS has the same pin out as the Hitachi and I suspect the Sony very different to the Cypress I guess thats the odd one out. Hitachi has the HM, I dont know how it compares with the Sony.

When I changed longer ribbon cable and made double connection to gnd all started to work as it should. I did not consider the because the only one I could buy easily is made by Cypress and on that the data lines do not correspond to the CXK: Losses in inductor of a boost converter 8.

Hierarchical block is unconnected 3. All times are GMT Click the register link above to proceed. Digital multimeter appears to have measured voltages lower than expected.

Thread Tools Show Printable Version. Input port and input output port declaration in top module 2. If this is your first visit, be sure to check out the FAQ by clicking the link above.

32,768-word × 8-bit High Speed CMOS Static RAM

How reliable is it? SRAM simultaneous read and write? Distorted Sine output from Transformer 8. Gnd was connected via a longer ribbon cable. Similar Threads 6T Sram read write simulation using cadence 3.

How do you get an MCU design to market quickly? SRAM is connected as in the schematic.

However when I removed the bad ram I could see printed beneath the chip: CMOS Technology file 1. I have the correct type ordered, Im just curious and have been unable to find a pin out for the latter. Dec 248: Rewrite Read and Write functions as follows: Synthesized tuning, Part 2: Anyone know of datasheeg manufacturer that makes a correct ?


You may have to register before you can post. You have RAM and processor driving the bus simultaneously, e. PV charger battery circuit 4. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.

Control lines are going thru single wires about 25cm long. The time now is Results 1 to 4 of 4. The time now is Analog Layout Finger Size 4. Thank you for your help! So far looks promising.
