Product details

256Kbit asynchronous SRAM — 15 ns access in a legacy 5V bus

The CY7C199C-15VC is a 256Kbit (32K x 8) asynchronous SRAM from Infineon (formerly Cypress) with a 15 ns access time and a parallel interface. The 15 ns access time is fast enough for 5V legacy bus architectures running at 33 MHz or slower without wait states, provided the board trace delay and capacitive loading stay within the timing budget.

Procurement for the CY7C199C-15VC is handled through independent distribution and surplus channels.

Package and temperature — 28-SOJ with commercial range

The SOJ footprint is a legacy form factor; any drop-in replacement must match this mechanical outline and pinout.

Frequently asked questions

What is the replacement for the CY7C199C-15VC?

Infineon has not published a direct pin-compatible replacement for the CY7C199C-15VC. Any alternative must be a 256Kbit (32K x 8) asynchronous SRAM in a 28-SOJ package with a 15 ns or faster access time and a 5V supply. Cross-references from other manufacturers (e.g., ISSI, Alliance Memory) should be verified for pinout and timing compatibility.

Does the CY7C199C-15VC have a RoHS compliant version?

The evidence does not specify RoHS compliance for this specific order code. Check the part marking and the latest Infineon environmental compliance document for the CY7C199 base number.
