Overview
Description
The 70125 is a high-speed 2K x 9 Dual-Port Static RAM designed to be used as a "SLAVE" Dual-Port together with the 70121 "MASTER" in 18-bit-or-more word width 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.
Features
- Fully asynchronous operation from either port
- Used with MASTER 70121 easily expands data bus width to 18 bits or more
- BUSY output flag on Master
- BUSY input on Slave
- INT flag for port-to-port communication
- Battery backup operation—2V data retention
- TTL-compatible, signal 5V (±10%) power supply
- Available in 52-pin PLCC package
- Industrial temperature range (–40C to +85C) is available

How to boot Da14580 from external flash
Hi.... We are using smart_tag app on DA14580 chip with the same schematic as define by Dialog. If we run code using JTAG there is no problem we can detect our tag. But when we Burn the flash using smart snippets tool the device is not boot from external ...
