7015- Block Diagram
Description
The 7015 is a high-speed 8K x 9 Dual-Port Static RAM designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 18-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 18- 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 CE permits the on-chip circuitry of each port to enter a very low standby power mode.

DA14583 UART boot sequence
Dear Dialog, I'm currently struggling to get the PLTD running against the DA14583. The UART boot doesn't seem to work in our setup (RX goes high by PLTD but no answer from the DA14583 on the TX). The time that RX is high is about 355ms after VBAT ...
