Cypress Semiconductor Corp S25FL512SDPBHV210

Overview

S25FL512SDPBHV210 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply, uniform 256-KB sectors, Quad Read up to 52 MBps, and integrated hardware ECC for single-bit error correction. It operates across industrial temperature range (–40°C to +85°C) in SO16 package and supports AutoBoot for embedded boot code execution.

For engineers reviewing the S25FL512SDPBHV210 datasheet, S25FL512SDPBHV210 pinout, S25FL512SDPBHV210 application, or S25FL512SDPBHV210 equivalent, key selection criteria include Quad DDR read performance (80 MBps), OTP security array (1024 bytes), AEC-Q100 Grade 3 qualification, 100,000 program-erase cycles, and CFI/SFDP compliance for firmware configuration portability.

Technical Context

This FL-S family device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density NOR flash with deterministic timing and robust data retention. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) support mixed-signal SoC interfacing while maintaining full command compatibility with S25FL-A/K/P families.

The logic block integrates SRAM-based control path, X/Y decoders, and configurable data latch supporting SDR/DDR modes, multi-I/O protocols (1-/2-/4-line), and hardware-managed erase/program algorithms. RESET#, HOLD#, and WP# pins enable system-level power sequencing, suspend/resume, and write protection independent of software state.

FAQ

What is the maximum clock frequency supported for Quad DDR read operations?

The S25FL512SDPBHV210 supports Quad DDR read at up to 80 MHz clock frequency, delivering 80 MBps throughput when VIO = VCC = 3.0–3.6 V. This mode requires proper setup of the DDR enable bit in the configuration register and strict adherence to AC timing parameters including tDSH and tDHD as specified in Section 5.5 of the datasheet.

Does this device require external hardware for error correction?

No. The S25FL512SDPBHV210 includes fully integrated hardware ECC that automatically detects and corrects single-bit errors during read operations without CPU involvement or external circuitry. The ECC engine operates transparently and does not affect read latency or require firmware configuration.

Can the AutoBoot address be changed after initial programming?

Yes. The AutoBoot address is stored in a dedicated configuration register (CR3[7:0]) and can be modified using the Write Configuration Register command (01h). Changes take effect after power cycle or RESET#, and require prior Write Enable (06h) and proper unlock sequence if Advanced Sector Protection is active.

Is the SO16 package RoHS-compliant and lead-free?

Yes. The S25FL512SDPBHV210 in SO16 package is Pb-free and RoHS-compliant per EU Directive 2011/65/EU, with JEDEC-standard matte tin finish on leads. The device meets IPC/JEDEC J-STD-020 moisture sensitivity level MSL-3 and is qualified for reflow soldering per IPC-7095 guidelines.
