Memory IC datasheet and documents for CY14B256L-SP45XC
Memory IC Overview
The CY14B256L-SP45XC is a 256-Kbit (32K x 8) non-volatile static RAM utilizing QuantumTrap technology. It operates on a single 3V supply (+20%, -10%) and features a 45 ns access time. The device integrates SRAM with unlimited read/write cycles and non-volatile memory supporting 200,000 store cycles. Data retention is specified for 20 years at 55°C. It is available in a 48-pin SSOP package.
Memory IC Feature Summary
- Integrates fast static RAM with embedded QuantumTrap non-volatile elements for data preservation.
- Supports automatic STORE operations upon power down using an external capacitor.
- Enables software-controlled or hardware-initiated STORE and RECALL sequences.
- Provides pin compatibility with STK14D88 devices.
Memory IC Applications
- Data logging systems requiring persistent storage without battery backup.
- Configuration memory for industrial control equipment.
- Embedded systems needing reliable state retention during power interruptions.
Memory IC Procurement Notes
Verify the specific suffix 'XC' against official Cypress/Infineon documentation to confirm commercial temperature range and package type. Confirm RoHS compliance status as required by your manufacturing standards. Check for 'Not Recommended for New Designs' notices in current datasheets before finalizing procurement plans.
Memory IC Selection Notes
Select this component when a parallel interface nvSRAM with 32K x 8 organization is required. Ensure the system design accommodates the VCAP pin requirements for AutoStore functionality. Verify that the 45 ns access time meets the system timing constraints. Consider the 48-pin SSOP package dimensions for PCB layout.
