MK48Z02B-20 is a type of non-volatile static random access memory (NVRAM) integrated circuit (IC) manufactured by NXP Semiconductors. It is a 5V, 2048-bit (256 x 8) NVRAM with a real-time clock (RTC) and automatic power-fail detection and switch circuitry.
Features
- 2048 bits of non-volatile RAM organized as 256 words by 8 bits.
- Real-time clock (RTC) with programmable alarm and periodic interrupt.
- Automatic power-fail detect and switch circuitry.
- Battery backup for data retention.
- Industrial temperature range (-40°C to +85°C) operation.
- 5V power supply voltage.
- JEDEC standard 32-pin DIP (Dual Inline Package) or SOIC (Small Outline Integrated Circuit) package options.
- Data retention for minimum of 10 years.
Application
- Embedded systems where reliable non-volatile data storage is required, such as in industrial control systems, medical equipment, automotive electronics, and security systems.
- Systems that need a real-time clock (RTC) functionality, such as time-stamping, event logging, or time-sensitive data recording.
- Applications where power-fail detection and switch circuitry is necessary to ensure proper data handling during power interruptions or failures.
- Any application that requires non-volatile data storage with battery backup.
