Dual-port architecture and bus arbitration
As a true dual-port SRAM, the 70V05L15PFG provides two independent address, data, and control buses that allow simultaneous access from two bus masters — typically a microcontroller and a DSP, or two processors in a shared-memory system. The 15 ns write cycle time (word and page mode) matches the read access time, so the bus can sustain back-to-back read-write operations at the same clock rate without wait states. Internal arbitration logic handles simultaneous access to the same memory location; the BUSY flag signals contention to the losing master, which must retry the cycle.
The 64Kbit capacity suits small mailbox buffers, FIFO implementations, or register-file extensions where two processors exchange status and command data without a serial link.
Lifecycle and compliance status
ROHS3 compliant (per), with no exemptions that would restrict EU or global shipments.
