... This text does not indicate orientation of the the actual part-marking. Low-power (L) versions offer battery backup data retention capability with typical power consumption of 500 W from a 2V battery. The IDT7006 is packaged in a ceramic 68-pin PGA, a 68- pin quad flatpack, a 68-pin PLCC, and a 64-pin TQFP (thin CE plastic quad flatpack) . Military grade product is manufactured ...

... The semaphore flags are active low. A token is requested by writing a zero into a semaphore latch and is released when the same side writes a one to that latch. The eight semaphore flags reside within the IDT7006 in a separate memory space from the Dual-Port RAM. This address space is accessed by placing a low input on the ...

... USING SEMAPHORES—SOME EXAMPLES Perhaps the simplest application of semaphores is their application as resource markers for the IDT7006’s Dual-Port RAM. Say the 16K x 8 RAM was to be divided into two blocks which were to be dedicated at any one time to servicing either the left or right port ...
