- Versatile control for write: separate write control for lower and upper byte of each port
- easily expands data bus width to 32 bits or more using SLAVE
- On-chip port arbitration logic
- BUSY output flag
- Fully asynchronous operation from either port
- Battery backup operation–2V data retention
- TTL-compatible
- single 5V (±10%) power supply
- Available in 68-pin ceramic PGA, Flatpack, PLCC and 100-pin TQFP packages
- Industrial temperature range (–40C to +85C) is available
説明
The 7133 high-speed 2K x 16 Dual-Port Static RAMs is designed to be used as a stand-alone 16-bit Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the 7143 "SLAVE" Dual-Port in 32-bit-or-more word width systems. Low-power (LA) versions offer battery backup data retention capability, with each port typically consuming 200μW for a 2V battery. Military grade product in compliance with MIL-PRF-38535 QML is available.
