Features
- True dual-ported memory cells, which allow simultaneous reads of the same memory location
- Fully asynchronous operation from either port
- TTL-compatible
- single 5V (±10%) power supply
- Available in 52-pin PLCC and 64-pin TQFP packages
- Industrial temperature range (–40°C to +85°C) is available
Description
The 7014 is a high-speed 4K x 9 dual-port static RAM designed to be used in systems where on-chip hardware port arbitration is not needed. This part lends itself to high-speed applications which do not rely on BUSY signals to manage simultaneous access. It utilizes a 9-bit wide data path to allow for parity at the user's option, which is useful in data communication applications where it is necessary to use a parity bit for transmission/ reception error checking.

Problem with LCD on yrdkrx62n
LCD doesn't work if PORT2.DDR.BYTE = 0x1A and by doesn't work, I mean it will not display backlight, so you can't see anything on it. By changing value to 0x18, or to 0, LCD backlight works ok.

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 ...
