Product details

The Renesas 7203L12JG is an asynchronous FIFO memory from the 7200 series, organized as 2K x 9 bits (18 Kbit total).

Asynchronous operation and retransmit capability

This is a true asynchronous FIFO: separate read and write clocks (or strobes) with independent enable pins. No FWFT (First-Word Fall-Through) support means the first written word does not appear on the outputs until the first read strobe — a standard synchronous-style read cycle. The retransmit capability allows resetting the read pointer to the beginning of the FIFO without clearing the data, useful for retry-on-error protocols. Expansion is supported in both depth and width, so multiple 7203L12JG devices can be cascaded for larger buffers.

For a BOM that requires a 2K x 9 asynchronous FIFO in a 32-PLCC, this is a direct fit with no substitution risk.

Frequently asked questions

What is the closest pin-compatible alternative to 7203L12JG?

Within the 7200 series, the 7203L12JG is a specific speed grade (12 ns) and package (32-PLCC). A pin-compatible alternative would be another 7200-series FIFO with the same 32-PLCC footprint and 2K x 9 organization, but with a different access time (e.g., 15 ns or 20 ns). No exact replacement with identical speed and package is listed as an official cross-reference. For a drop-in replacement, verify the access time and supply voltage match the system timing budget.
