FM28V102A 1-Mbit (64 K 16) F-RAM Memory 1-Mbit (64 K 16) F-RAM Memory Industrial temperature: 40 C to +85 C Features 44-pin thin small outline package (TSOP) Type II 1-Mbit ferroelectric random access memory (F-RAM) logically organized as 64 K 16 Restriction of hazardous substances (RoHS) compliant Configurable as 128 K 8 using UB and LB 14 Functional Overview High-endurance 100 trillion (10 ) read/writes 151-year data retention (see the Data Retention and The FM28V102A is a 64 K 16 nonvolatile memory that reads Endurance table) and writes similar to a standard SRAM. A ferroelectric random NoDelay writes access memory or F-RAM is nonvolatile, which means that data Page mode operation to 30-ns cycle time is retained after power is removed. It provides data retention for Advanced high-reliability ferroelectric process over 151 years while eliminating the reliability concerns, functional disadvantages, and system design complexities of SRAM compatible battery-backed SRAM (BBSRAM). Fast write timing and high Industry-standard 64 K 16 SRAM pinout write endurance make the F-RAM superior to other types of 60-ns access time, 90-ns cycle time memory. Superior to battery-backed SRAM modules The FM28V102A operation is similar to that of other RAM No battery concerns devices and therefore, it can be used as a drop-in replacement Monolithic reliability for a standard SRAM in a system. Read cycles may be triggered True surface mount solution, no rework steps by CE or simply by changing the address and write cycles may Superior for moisture, shock, and vibration be triggered by CE or WE. The F-RAM memory is nonvolatile due to its unique ferroelectric memory process. These features Low power consumption make the FM28V102A ideal for nonvolatile memory applications Active current 7 mA (typ) requiring frequent or rapid writes. Standby current 120 A (typ) The device is available in a 400-mil 44-pin TSOP-II Sleep mode current 3 A (typ) surface mount package. Device specifications are guaranteed Low-voltage operation: V = 2.0 V to 3.6 V over the industrial temperature range 40 C to +85 C. DD For a complete list of related documentation, click here.
