It is designed to provide data storage reliability and superior data retention with minimal power consumption.

Application Field

The BR93H86RF-2CE2 devices are widely used in industrial systems, consumer and automotive electronics applications. It is designed to be used in applications like digital cameras, notebook PCs, mobile phones, point-of-sale terminals, smart cards, digital household appliances, and automotive electronics modules. It is suited for applications where small size and low power are desirable.

Working Principle

The BR93H86RF-2CE2 utilizes a two-cell ultra-low-power phosphor PROM memory cell. The 2-cell PROM consists of two 1T-1C (one transistor and one capacitor) memory cells connected in series. The memory cell consists of a field effect transistor and a nonvolatile storage capacitor. The storage capacitor is charged or discharged depending on the logic state of the transistor, which provides the nonvolatile data storage. The device is programmed and erased by direct current and has a write cycle time of 10µs.

The PROM also contains a Nonvolatile Memory Controller (NVM) that provides the interfacing with the host microcontroller. The NVM is based on a single-cycle state machine architecture with 10bit addressing and 128 bytes of EEPROM memory space. The device also has a data register which handles the data transfer between the NVM and the host microcontroller. It also has a Reliability Tolerance Voltage module to ensure reliable data retention.

The BR93H86RF-2CE2 device is a low-power and reliable memory device with superior characteristics. Its small size and low power consumption make it suitable for a range of applications, from consumer to industrial systems. The device also provides data retention reliability and superior performance with minimal power consumption.
