Product details

Obsolete — sourcing and replacement

The CY7C1021BNL-15ZXCT is officially obsolete, per the manufacturer's product status. No direct pin-compatible replacement is listed in the available records.

1 Mbit organized 64K x 16

Organized as 64K words by 16 bits, this part fits 16-bit data bus applications directly — no byte-lane muxing needed. The 1 Mbit density suits moderate-depth buffers, cache tag stores, and lookup tables in embedded controllers and telecom line cards. The 15 ns write cycle time matches the read access, enabling back-to-back transactions at full bus speed.

Frequently asked questions
