70T653MS15BC8 is listed in the Memory IC range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is IC SRAM 18MBIT PARALLEL 256CABGA. Review the specifications below when checking this part for your BOM.
The Renesas Electronics Corporation 70T653MS15BC8 is an asynchronous dual-port static random-access memory (SRAM) IC. It provides a total storage capacity of 18 Mbit, organized as 512K words by 36 bits. The device features a parallel interface with a maximum access time of 15 ns. It operates within a supply voltage range of 2.4 V to 2.6 V and supports surface-mount installation in a 256-CABGA package measuring 17x17 mm. The component is rated for commercial operating temperatures between 0°C and +70°C.
Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt to ensure suitability for automated assembly processes. Check for moisture sensitivity handling precautions during storage and reflow soldering.
Select this component when asynchronous dual-port functionality is required for specific memory architectures. Ensure system design accommodates the 2.5V nominal supply voltage and CABGA-256 footprint. Consider the 15 ns access speed against application latency requirements. Evaluate thermal management needs for the specified commercial temperature range.
This part belongs to the 70T653M series of asynchronous dual-port SRAMs from Renesas. It shares architectural similarities with other variants in the family but differs in access speed and suffix specifications. The series targets applications requiring simultaneous access to shared memory resources without complex arbitration logic.
