S25FL127SABBHVD03

Memory IC Overview

The S25FL127SABBHVD03 is a 128 Mb (16 MB) non-volatile NOR flash memory utilizing 65-nm MIRRORBIT™ technology and Eclipse architecture. It operates on a 3.0 V core with a supply voltage range of 2.7 V to 3.6 V. The device supports SPI multi-I/O interfaces including Single, Dual, and Quad I/O modes, achieving maximum read speeds of 108 MHz. It features a hybrid sector size option with sixteen 4-KB sectors and remaining 64-KB sectors, or uniform 256-KB sectors. Programming utilizes 256- or 512-byte page buffers, while erasure supports 4-KB, 64-KB, and 256-KB block sizes. The component includes an OTP array, hardware ECC, and advanced sector protection.

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with host system voltage levels and SPI clock requirements. Confirm availability status directly with authorized distributors as product lifecycles may change. Cross-reference the full part number with Infineon's current production announcements to avoid obsolete components.

Memory IC Selection Notes

Select this component when a 128 Mb density is required with high-speed Quad Read capabilities up to 108 MHz. The Eclipse architecture provides superior programming performance compared to prior floating gate generations. Consider the hybrid sector option if small boot code storage is needed alongside larger uniform data blocks. Verify that the host controller supports the necessary SPI Multi-I/O command set and extended addressing options.

Memory IC Part Context

This device belongs to the FL-S family of SPI flash memories, succeeding the FL-K and FL-P series. It maintains footprint and command set compatibility with previous generations while introducing enhanced performance through the Eclipse architecture. The FL-S family offers increased density options and improved data integrity features such as automatic ECC and advanced sector protection not found in earlier models.

Memory IC Replacement Considerations

The S25FL127SABNFI103 is listed as a substitute part number by distributors. Verify pinout and electrical specifications before substitution. Prior generation FL-K and FL-P devices are compatible but offer lower performance metrics. Ensure any replacement matches the required package style and operating temperature range.

Memory IC FAQ

Does the S25FL127S support Deep Power Down mode?

No, the Deep Power Down function is not supported in FL-S family devices. The legacy DPD command code is repurposed to enable the bank address register for accessing higher memory densities.

What is the difference between the hybrid and uniform sector options?

The hybrid option provides sixteen 4-KB sectors at the top or bottom of the address space with all other sectors being 64 KB. The uniform option configures all sectors as 256-KB blocks for software compatibility with higher density devices.
