Description

The CY7C1339-100AC is an IC Chip from Cypress Semiconductor Corp. It is a synchronous static Random Access Memory (SRAM) that integrates 131,072 x 32 SRAM cells with advanced peripheral circuitry and counters to support internal burst operations. This device has registered inputs and outputs, and it uses pipelined operation to boost performance.

Specifications and features

• Common I/O architecture: 128K × 32
• Power supply: 3.3V for core and 2.5V / 3.3V for I/O
• User-selectable burst counter for Intel® Pentium® interleaved or linear burst sequences
• Synchronous self-timed writes and asynchronous output enable
• Sleep Mode Option: "ZZ"
• Fast clock-to-output times:
  • 2.6 ns (for 250-MHz device)
  • 2.8 ns (for 200-MHz device)
  • 3.5 ns (for 166-MHz device)
  • 4.0 ns (for 133-MHz device)
• Lead-Free 100-pin TQFP and 119-ball BGA packages

Application Scenarios

The CY7C1339-100AC is commonly used in electronic devices such as routers, switches, and other communication equipment which require high-speed and reliable data storage capabilities.

Comparison

• High performance with fast clock-to-output times for various devices
• User-selectable burst counter for flexible burst operation
• Registered inputs and outputs for pipelined operation to boost performance

• Not suitable for low-power applications as it requires a 3.3V core power supply
• Limited package options: only 100-pin TQFP and 119-ball BGA packages
