DSC 5623/7 is a dual-port high-speed cache memory chip launched by Integrated Device Technology in 2003. Its features are true dual-port memory cells that allow simultaneous access to the same memory location, and support high-speed data access. The commercial frequency can reach 3.6ns (166MHz) and the industrial frequency can reach 4.2ns (133MHz)
The IDT 70V3319/99S provides true dual‑port memory cells, allowing simultaneous access to the same location from both ports. It supports high‑speed data access (up to 166 MHz commercial, 133 MHz industrial) with pipelined or flow‑through output modes, counter enable, repeat features, and optional JTAG for testing. The device operates from a single 3.3 V core supply and offers selectable 3.3 V or 2.5 V I/O voltage via the OPT pins.
The part is offered in 128‑pin TQFP, 208‑pin fine‑pitch BGA, and 256‑pin BGA packages, covering commercial (0 °C to +70 °C) and industrial (‑40 °C to +85 °C) temperature ranges. Electrical specifications include a core VDD of 3.15‑3.45 V, input leakage ≤10 µA, and dynamic operating currents up to 500 mA (commercial) or 400 mA (industrial).
| Core Supply Voltage (VDD) | 3.15 V – 3.45 V (typ 3.3 V) |
