Infineon Technologies S25FL512SAGMFVR13

Overview

S25FL512SAGMFVR13 from Infineon is a 512 Mb (64 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 3.0 V core supply, uniform 256-KB sectors, Quad-Input Page Programming, and integrated hardware ECC. It supports Fast/Quad/DDR read modes up to 80 MHz DDR clock (80 MBps Quad Read DDR), operates from –40°C to +105°C (Industrial Plus), and is packaged in 16-pin SOIC (300 mil).

For engineers reviewing the S25FL512SAGMFVR13 datasheet, S25FL512SAGMFVR13 pinout, S25FL512SAGMFVR13 application, or S25FL512SAGMFVR13 equivalent, key selection criteria include SPI Multi-I/O timing compatibility with S25FL-P family, AutoBoot address configuration, OTP security array size, sector protection granularity, and AEC-Q100 Grade 2 qualification for automotive use.

Technical Context

This FL-S series flash implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling single-bit error correction via on-die ECC logic and supporting both standard SPI (modes 0/3) and DDR command protocols. The device uses a 32-bit extended addressing scheme and maintains CFI and JEDEC JESD216 SFDP compliance for standardized configuration discovery.

Its dual-supply design separates core (VCC: 2.7–3.6 V) and I/O (VIO: 1.65–3.6 V) rails, allowing interoperability with 1.8 V or 3.3 V host controllers. The control logic integrates dedicated registers for Advanced Sector Protection (ASP), block-level write/erase lock, and programmable AutoBoot execution at power-up or reset.

FAQ

What is the maximum supported clock frequency for Quad Read DDR mode?

The S25FL512SAGMFVR13 supports Quad Read DDR at up to 80 MHz clock frequency, delivering 80 MBps effective throughput when VIO = VCC = 3.0–3.6 V. This is confirmed in the Performance Summary table (Datasheet Rev. *U, page 3) and requires proper DDR timing setup including tDQSH and tDQSL parameters per AC specifications section.

Does this part support hardware write protection independent of software commands?

Yes - WP# pin provides hardware-level write protection for status register bits and sector protection registers. When WP# is held low, it prevents modification of BP bits and SRWD, regardless of software command issuance. This behavior is defined in Section 2.8 and Section 8.3 of the datasheet and remains active across power cycles.

Can the AutoBoot feature execute from any address in the memory array?

No - AutoBoot is configurable only to launch a Normal or Quad Read command from one of four predefined addresses: 0x000000, 0x000001, 0x000002, or 0x000003. These addresses are selected via STATUS REGISTER bits [11:10] (BOOT_ADD[1:0]) and cannot be programmed to arbitrary locations.

Is the 1024-byte OTP array permanently locked after programming?

Yes - once any byte in the 1024-byte OTP array is written, the entire array becomes permanently read-only. There is no provision for erasure or reprogramming. This irreversible behavior is enforced by on-die fuses and documented in Section 8.1 and Section 9.7 of the datasheet.
