MCM4164BP15 64Kbit Dynamic RAM IC DIP 16-Pin
The MCM4164BP15 is a Motorola-manufactured commercial‑grade 64 Kbit (65,536 × 1‑bit) dynamic random‑access memory chip. It provides fixed +5.0 V ±10 % single‑supply operation, a maximum access time of 150 ns, and a standard JEDEC DIP‑16 pinout. The device supports page‑mode read/write for faster sequential access and offers TTL‑compatible inputs with three‑state output buffers. It is fully cross‑compatible with the original 4164 family of TTL DRAMs.
Features
- Organized as 65,536 Words of 1 Bit.
- Single +5 V operation (±10 %).
- Maximum access time: 150 ns.
- Low power dissipation: 275 mW maximum (Active) and 22 mW maximum (Standby).
- Three-state data output.
- Internal latches for address and data input.
- Early-write common I/O capability.
- 16K-compatible 128-cycle, 2 ms refresh.
- RAS-only refresh mode.
- CAS-controlled output.
- Upward pin compatibility with 16K RAM (MCM4116, MCM4517).
- Fast page-mode cycle time.
