CY7C1399BL-15ZXC

Product Overview

The CY7C1399BL-15ZXC from Cypress Semiconductor Corp is a volatile asynchronous SRAM device with a 256Kbit memory size organized as 32K x 8. It uses a parallel memory interface and is specified with a 15 ns access time and a 15 ns write cycle time for word and page operations. The device operates from a 3V to 3.6V supply and is offered in a 28-TSOP I surface-mount package, corresponding to a 28-TSSOP case with 0.465 inch, 11.80mm width. Its operating temperature range is 0°C to 70°C (TA).

Key Features

• 256Kbit asynchronous SRAM with a 32K x 8 memory organization.
• Parallel interface with 15 ns access time and 15 ns word/page write cycle time.
• 3V to 3.6V supply voltage range.
• Surface-mount 28-TSOP I package, 28-TSSOP 0.465 inch, 11.80mm width.
• Operating temperature range of 0°C to 70°C (TA).

Applications

• Volatile memory expansion in embedded systems that use a parallel bus.
• Local data buffering in microcontroller or processor-based designs.
• Temporary storage in equipment designs requiring a surface-mount asynchronous SRAM.

Design & Procurement Notes

When integrating the CY7C1399BL-15ZXC, verify that the host bus can drive a parallel SRAM with 32K x 8 addressing and that the selected supply remains within 3V to 3.6V. The 15 ns access and write cycle timing should be checked against the controller's read and write timing requirements. The 0°C to 70°C (TA) operating range may limit designs intended for wider temperature environments. The 28-TSOP I surface-mount package requires footprint and land-pattern compatibility with the 28-TSSOP 0.465 inch, 11.80mm width case.
