Features
- True Dual-Ported memory cells which allow simultaneous reads of the same memory location
- 7008 easily expands data bus width to 16 bits or more
- Interrupt Flag
- On-chip port arbitration logic
- Full on-chip hardware support of semaphore signaling between ports
- Fully asynchronous operation from either port
- Battery backup operation—2V data retention
- TTL-compatible, single 5V (±10%) power supply
- Available in 84-pin PGA, PLCC, and 100-pin TQFP packages
- Industrial temperature range (-40C to +85C) is available
Description
The 7008 is a high-speed 64K x 8 Dual-Port Static RAM designed to be used as a stand-alone 512K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more word systems. An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.

Need for Demo software to show the RSSI-value of the packet at screen
I have SmartBond DA14583 nibbets and a DA14583DEVKT-B and a software which detects packets and sends sequentically a nr of 1-255 to COM port via USB. It would be much better to get RSSI-value of the packet signal - too. Do we have a demo test software of ...
