Features
- True Dual-Port allows simultaneous reads of the same memory location
- Separate upper-byte and lower-byte control for multiplexed bus compatibility
- 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 100-pin TQFP package
- Industrial temperature range (–40C to +85C) is available
Description
The 7035 is a high-speed 8K x 18 Dual-Port Static RAM designed to be used as a stand-alone 144K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit or more word systems. This MASTER/SLAVE approach in 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. An automatic power down feature controlled by Chip Enable (CE) permits the on-chip circuitry of each port to enter a very low standby power mode.

Disconnect issue with DA14580 (Murata LBCA2HNZYZ)
Dear Dialog, I've developed a product with a Murata LBCA2HNZYZ BLE module (which includes a DA14580 chip). That product has two modules, one is a central and the other one is a peripheral. But after connected to each other, peripheral never responds a few times an hour. The distance ...

app_timer_set callback questions
I'm using an app_timer callback to run some potentially lengthy (could occasionally be up to 100ms or so) code every second. At the end of the callback, I call app_timer_set to restart the timer. I'm having a very intermittent issue in my application: after anywhere ...
