Asynchronous FIFO for data buffering
The Renesas 7202LA25JGI is a 9K (1K x 9) asynchronous FIFO from the 7200 series, designed for unidirectional data buffering between clock domains or bus-width matching. With a 25 ns access time and a 28.5 MHz data rate, this FIFO suits moderate-speed parallel interfaces where the read and write clocks are independent and no frame-sync is required.
Memory depth and expansion
Organised as 1,024 words by 9 bits, the 7202LA25JGI supports depth and width expansion without external logic — multiple devices cascade to build larger buffers while maintaining the same 25 ns access window. Retransmit capability is included, allowing the FIFO to re-read data from the beginning without a full reset — useful in packet retry or diagnostic loops.
Package and temperature grade
Housed in a 32-lead PLCC (J-Lead) package with a body size of 14 mm x 11.46 mm (supplier device package 32-PLCC), the part is surface-mount and requires a standard PLCC-32 footprint with J-bend solder joints.
