Product details

36K synchronous FIFO — 66.7 MHz pipeline buffer

The CY7C4235V-15ASXC is a 36-Kbit synchronous FIFO organized as 2K words by 18 bits, clocked at a 66.7 MHz data rate with an 11 ns access time. This is a unidirectional, synchronous FIFO with depth and width expansion capability, retransmit support, and programmable flags — features that suit it for rate-matching and temporary data buffering in DSP pipelines, network processors, and test equipment.

64-LQFP footprint and board integration

For mixed-voltage designs (e.g., 2.5 V core with 3.3 V I/O), the FIFO sits on the 3.3 V bank.

Frequently asked questions

What is the memory organization and speed of this FIFO?

It is a 36-Kbit FIFO organized as 2K words by 18 bits, with a 66.7 MHz maximum clock rate and an 11 ns access time. The 18-bit word width allows it to buffer 16-bit data plus two control/parity bits in a single device.

What package does the CY7C4235V-15ASXC come in?

It is supplied in a 64-lead LQFP (also designated 64-TQFP, 14x14 mm body) on a tray. The 0.5 mm pitch requires a fine-pitch PCB layout.
