Visão Geral
Description
### Key Features:
- Battery-backed operation: Uses an integrated lithium energy source to retain data and timekeeping during power loss.
- RTC functionality: Tracks seconds, minutes, hours, date, month, year, and leap years in BCD format.
- 70ns access time: Suitable for embedded systems requiring fast SRAM access.
- Power-fail protection: Automatically switches to battery power when main power is lost.
- 28-pin DIP package: Easy integration into legacy systems.
### Applications:
- Industrial controls, medical devices, and embedded systems needing non-volatile timekeeping and memory.
This module ensures reliable data retention and accurate timekeeping, making it ideal for applications requiring persistent memory and timestamping.
Equivalent
- STK48T35-70PC1 (Simtek)
- DS1643-70+ (Maxim Integrated)
- MK48T35-70PC1 (STMicroelectronics)
- DS1243Y-70+ (Maxim Integrated, NV SRAM alternative)
These are pin-compatible or functionally similar NV SRAM/Timekeeper chips with battery backup. Verify datasheets for exact compatibility.
Features
- Non-volatile SRAM: Combines SRAM with a built-in lithium energy source for data retention.
- Capacity: 32K × 8 (256 Kb).
- Battery Backup: Integrated lithium cell maintains data for 10+ years without power.
- Access Time: 70 ns (fast read/write operations).
- Operating Voltage: 4.5V to 5.5V.
- Low Power Consumption: Optimized for battery-backed applications.
- DIP Package: 28-pin DIP (Dual In-line Package) for easy integration.
- Industrial Temp Range: 0°C to +70°C (commercial grade).
- Automatic Power-Fail Protection: Switches to battery backup on power loss.
Ideal for real-time clocks (RTC), embedded systems, and critical data storage requiring non-volatility.
