Frequently Asked Questions
What is the memory capacity of the M48T58Y-70PC1?
The M48T58Y-70PC1 integrates 8192 bytes (8KB) of SRAM that retains data using an internal battery backup, eliminating the need for external battery circuits or EEPROM for small-volume non-volatile storage requirements.
What supply voltage does the M48T58Y-70PC1 require?
The M48T58Y-70PC1 operates from a 4.5V to 5.5V supply voltage through a parallel interface, making it directly compatible with standard 5V TTL and CMOS logic levels commonly used in industrial and embedded computing systems.
What package does the M48T58Y-70PC1 use?
The M48T58Y-70PC1 is housed in a 28-pin PCDIP (Plastic Ceramic Dual In-Line Package), a through-hole package that is easy to socket for prototyping or field replacement in industrial equipment and legacy computing systems.
How does the battery backup work in the M48T58Y-70PC1?
The M48T58Y-70PC1 contains an internal lithium battery that automatically powers the RTC and SRAM when the main Vcc supply is absent or falls below the threshold, ensuring timekeeping accuracy and data retention without any external power management circuitry.
What are typical applications for the M48T58Y-70PC1?
Typical applications include BIOS real-time clocks in embedded computers, industrial data loggers, telecommunications switches, SCADA systems, and any equipment requiring accurate timestamping and persistent small-volume data storage across power cycles.
