The AM27S19DC is a high-speed 2048-bit (512 x 4) Schottky PROM (Programmable Read-Only Memory) manufactured by AMD. It is designed for applications demanding rapid data retrieval and utilizes Schottky transistor technology to achieve very fast access times. This PROM is suitable for use in control memories, code converters, and lookup tables where speed is critical.
Applications:
- High-speed control memories
- Code converters
- Lookup tables
- Character generators
- Microprogram storage
Features:
- 2048-bit (512 x 4) memory organization
- Schottky technology for high speed
- Fast access time (typically under 50ns)
- TTL compatible inputs and outputs
- Open collector outputs
- Programmable using standard PROM programmers
Benefits:
- High-speed operation allows for quick data access and processing.
- TTL compatibility simplifies integration with existing logic circuits.
- Non-volatile storage ensures data retention even when power is off.
- Programmability provides flexibility in design and implementation.
Additional Details:
The AM27S19DC is typically packaged in a 16-pin DIP (Dual In-line Package). Programming is achieved by selectively fusing internal links to create the desired memory pattern. The open collector outputs allow for easy expansion and OR-tying. The device requires a stable +5V power supply for proper operation. The operating temperature range is typically from 0°C to +70°C. The PROM is designed for reliable operation over a wide range of conditions. The address inputs are used to select the memory location to be accessed, and the output enable (OE) pin controls the output state.
