Understanding the 82S123 Datasheet and its Applications

The 82s123 Datasheet is essentially a comprehensive guide outlining the 82S123 PROM’s electrical characteristics, timing specifications, and functional behavior. This PROM stores data permanently after being programmed, meaning the stored information is retained even when power is removed. It was widely used in applications requiring small amounts of non-volatile memory, such as:

  • Character generators for early display systems
  • Lookup tables for digital circuits
  • Boot ROMs for simple microprocessors

The datasheet details the chip’s pinout, describing the function of each pin and how it interacts with the rest of the circuit. It also includes crucial electrical parameters like supply voltage, input and output voltage levels, and current consumption. Understanding these parameters is essential for designing a stable and reliable system using the 82S123. Furthermore, it offers timing diagrams that illustrate the precise sequence of events required to read data from the memory, ensuring proper operation. The 82s123 is usually organized as 32 words by 8 bits.

Datasheets will also show the operating conditions for different temperatures. The key parameters related to temperature are the storage temperature, the operating temperature, and the lead temperature during soldering. This is important in any kind of design because if any of these values are exceeded during manufacturing, installation, or operation, the 82s123 can be damaged.
Below is a table demonstrating how the 82s123 is organized.
