Frequently asked questions
What are the 70V27L20PFGI and 70V27L20PFI8?
Both are 3.3V 32K x 16 dual-port static RAM devices from the IDT (now Renesas) 70V27 series, offering 20 ns access time and housed in a 100-pin TQFP package. The 70V27L20PFGI is specified for the industrial temperature range, while the 70V27L20PFI8 is the tape-and-reel version of the same industrial-temperature device.
What is the difference between the 70V27L20PFGI and 70V27L20PFI8?
The core device is identical: both are 70V27L20PFI, 3.3V 32K x 16 dual-port SRAMs with 20 ns access time in a 100-pin TQFP package over the industrial temperature range. The only difference is the packaging option: the "G" suffix denotes a tray or tube shipment, while the "8" suffix denotes tape-and-reel packaging for automated assembly.
Are the 70V27L20PFGI and 70V27L20PFI8 electrically and functionally interchangeable?
Yes. Since both part numbers refer to the same base device (70V27L20PFI) with identical die, speed grade, voltage, and temperature rating, they are electrically and functionally interchangeable. The only distinction is the shipping packaging format.
What are the key specifications of the 70V27L20PFI device?
The 70V27L20PFI is a 3.3V dual-port SRAM with 32K x 16 organization (512 Kbit total), 20 ns maximum access time, asynchronous operation, and a 100-pin TQFP package. It supports simultaneous read/write access from two ports and operates over the industrial temperature range of -40°C to +85°C.
Can the 70V27L20PFGI and 70V27L20PFI8 be used in the same PCB footprint?
Yes. Both devices use the same 100-pin TQFP package with identical pinout and mechanical dimensions, so they share the same PCB land pattern and footprint. The choice between them depends only on the desired shipping format for manufacturing.
Which applications are suitable for the 70V27L20PFGI and 70V27L20PFI8?
These dual-port SRAMs are used in applications requiring simultaneous access to shared memory, such as communication buffers, multiprocessor systems, DSP/CPU interfacing, and real-time data acquisition. The industrial temperature rating makes them suitable for industrial and embedded systems.
What does the "8" suffix indicate on the 70V27L20PFI8?
The "8" suffix indicates tape-and-reel packaging. This is the same device as the 70V27L20PFI but supplied in tape-and-reel format for use with automated pick-and-place assembly equipment, whereas the "G" suffix on the 70V27L20PFGI indicates tray or tube packaging.
