Memory

The R1LP5256ESA-7SI#B0 is a fully integrated low power, non-volatile one-time programmable (OTP) memory. This type of memory consists of more than one kilobytes of user OTP memory and three kilobytes of dedicated small parameter block (SPB) which includes identification, signature, and data information. The R1LP5256ESA-7SI#B0 offers its unique features that are ideal for many applications.

Applications

The R1LP5256ESA-7SI#B0 can be used for multiple applications that require a reliable and secure permanence to store data. Since the memory is non-volatile, meaning it is not erased by an external source of power, the R1LP5256ESA-7SI#B0 is well-suited for applications requiring long-term data storage and persistence. These applications can range from personal identification systems, medical applications, automotive applications, or software security code encryption.

The R1LP5256ESA-7SI#B0\'s excellent Low Power supply makes the memory ideal for devices that are battery operated. This is true for devices that are powered solely by a battery, as well as those that have a mix of rechargeable and non-rechargeable power supplies. With its low power consumption, the R1LP5256ESA-7SI#B0 can easily support a variety of battery powered applications, both in the consumer electronics and the industrial automation markets.

The R1LP5256ESA-7SI#B0 can also be used for gaming machines since it can easily handle multiple designs that have a very short life time once the gaming software is loaded. This feature makes the memory extremely suited for applications such as slot machines and other gaming machines where the data is loaded and the game is played once only.

Working Principle

The R1LP5256ESA-7SI#B0 is a one-time programmable (OTP) device, which means it can only be written to once. This feature makes the memory very reliable and secure, as it is impossible to alter any data stored in the memory once it is written. This is useful for applications where data security and authenticity is of utmost importance.

The R1LP5256ESA-7SI#B0 is programmed in the factory by the manufacturer. Once programmed, the memory cannot be programmed again and can only be read. The memory is programmed by connecting the memory to a programming circuit and supplying it with a programming voltage. Once the voltage is applied, the memory will be programmed and the data will be stored. After programming, the voltage is removed and the memory is now ready to be used.

The SPB on the R1LP5256ESA-7SI#B0 is factory programmed with a unique identification code and signature. This allows the authenticity of the memory to be verified upon every power-on reset. The signature is programmed as a 128-bit unique code which is unique to each memory. Thissecures that the memory cannot be tampered with or altered without detection.
