Detailed Description for CY7C1345B-117AC
Product Overview
The CY7C1345B-117AC from Cypress Semiconductor Corp is a volatile synchronous SRAM device with a 4.5Mbit capacity organized as 128K x 36. It uses a parallel interface and operates from a 3.15V to 3.6V supply, with a 117 MHz clock frequency and 7.5 ns access time. The device is supplied in a surface-mount 100-LQFP package, with a 100-TQFP (14x20) device package, and is rated for an operating temperature range of 0°C to 70°C (TA).
Key Features
- 4.5Mbit volatile SRAM memory with 128K x 36 organization.
- Synchronous SDR operation at a 117 MHz clock frequency.
- 7.5 ns access time for parallel memory transfers.
- 3.15V to 3.6V supply voltage range.
- Surface-mount 100-LQFP package, 100-TQFP (14x20) device package.
- Operating temperature range of 0°C to 70°C (TA).
Applications
- Data buffering in embedded systems that use a parallel memory bus.
- Temporary storage for controller-side data handling in 0°C to 70°C (TA) hardware.
- Memory expansion in board-level designs requiring synchronous SRAM organization.
Design & Procurement Notes
When selecting the CY7C1345B-117AC, confirm that the host system can provide a 3.15V to 3.6V supply and that the PCB footprint matches the 100-TQFP (14x20) surface-mount package. The 128K x 36 organization and parallel interface require address and data bus planning consistent with the 4.5Mbit capacity. Because the device is synchronous SDR at 117 MHz with 7.5 ns access time, system timing should be evaluated against the controller clock and memory bus requirements. The 0°C to 70°C (TA) operating range should be checked against the intended ambient conditions.
