DESCRIPTION

· The DS1230Y/AB is a 256k Nonvolatile SRAM designed to replace 32k x 8 volatile static RAM, EEPROM, or Flash memory. It features a lithium energy source that remains disconnected until the first power application, ensuring data freshness. The device is available in a JEDEC standard 28-pin DIP package and a PowerCap Module (PCM) package, which is directly surface-mountable and includes a replaceable snap-on PowerCap for lithium backup battery.

FEATURES

· 10 years minimum data retention without external power.
· Automatic data protection during power loss.
· Unlimited write cycles.
· Low-power CMOS technology.
· 70 ns read and write access times.
· Full ±10% VCC operating range (DS1230Y).
· Optional ±5% VCC operating range (DS1230AB).
· Optional industrial temperature range of -40°C to +85°C.
· Standardized pinout for all nonvolatile SRAM products.
· Easy PowerCap removal with a regular screwdriver.

APPLICATIONS

· Ideal for applications requiring nonvolatile memory with high reliability and long data retention.
· Suitable for industrial environments with extended temperature ranges.
· Useful in systems where power loss protection is critical.
· Applicable in designs needing replaceable lithium backup batteries.
