Product details

512 Kbit parallel SRAM in 100-TQFP — what it is and where it fits

The IDT 70V27L20PFGI is a 512 Kbit parallel SRAM organized as 32K x 16, running from a 3 V supply with a 20 ns access time. It is a volatile memory for data buffering, cache, or working memory in industrial controllers, telecom line cards, and embedded systems that need fast, deterministic read-write cycles. The 100-pin TQFP package keeps the footprint compact for dense PCB layouts.

20 ns access time — what it means for the bus

The 20 ns access time sets the window for valid data on the bus after the address is stable. It leaves less margin than the 15 ns version (70V27L15PFG) for heavily loaded buses or long trace runs.

Industrial temperature range — deployment context

Rated -40°C to 85°C, this SRAM suits factory-floor PLCs, outdoor telecom cabinets, and engine-bay electronics. The package is surface-mount, so reflow profile and board-level thermal cycling should follow the JEDEC profile for that body size.

Frequently asked questions

Will the 70V27L15PFG drop in as a replacement for the 70V27L20PFGI?

The 70V27L15PFG is pin-compatible and functionally identical — same 32K x 16 organization, same 3 V supply, same 100-TQFP package — but rated for commercial temperature (0°C to 70°C) versus the -40°C to 85°C industrial range of this part. It also offers a faster 15 ns access time. If your operating environment stays within commercial limits, it is a drop-in substitute; otherwise, verify the temperature grade.

What compliance documentation does IDT provide for the 70V27L20PFGI?

The 70V27L20PFGI is listed as RoHS-compliant per the IDT/Renesas product marking. Full RoHS, REACH, and material declaration documents are available from the manufacturer's documentation portal.
