Infineon Technologies S40410081B1B1W000

Overview

S40410081B1B1W000 from Cypress Semiconductor is an 8 GB e.MMC 4.51-compliant embedded flash memory device with integrated controller, operating at 2.7–3.6 V (VCC) and 1.7–1.95 V or 2.7–3.6 V (VCCQ), delivering 120 MB/s sequential read and 20 MB/s sequential write in HS200 x8 mode, used for boot storage and high-reliability data storage in industrial embedded systems.

For engineers reviewing the S40410081B1B1W000 datasheet, S40410081B1B1W000 pinout, S40410081B1B1W000 application, or S40410081B1B1W000 equivalent, key selection criteria include HS200 timing support, RPMB partitioning, boot partition configuration, and 153-ball VFBGA mechanical compatibility.

Technical Context

This e.MMC device implements JEDEC JESD84-B451 compliance with full backward support to earlier e.MMC versions, integrating a Cypress-optimized flash controller managing MLC NAND with hardware ECC, wear leveling, garbage collection, and defect management. It supports three operational modes: SDR (up to 52 MHz), DDR (up to 52 MHz), and HS200 (up to 200 MHz) on configurable 1/4/8-bit data buses.

The architecture includes dedicated boot partitions (4 MB each, factory-configured in Enhanced SLC mode), a 4 MB Replay Protected Memory Block (RPMB), and user-configurable General Purpose Partitions - all programmable once per lifecycle. Power management features include CMD5 sleep, hardware reset (RST_N), and power-off notification.

FAQ

Is S40410081B1B1W000 pin-compatible with other Cypress e.MMC devices in the same package?

Yes - all S4041-1B1 series devices in the 153-ball VFBGA share identical pinout, power sequencing, and AC timing. The 8 GB (S40410081B1B1W000) and 16 GB (S40410161B1B1W000) variants are hardware interchangeable; only density and part marking differ.

Does this device support hardware-based cryptographic erase?

Yes - the Sanitize command performs hardware-accelerated cryptographic erase of all user data in under 100 ms, certified per NIST SP 800-88 Rev. 1. This erases data without affecting factory-configured boot/RPMB partitions or device identity registers.

What is the maximum sustained random write performance?

The device delivers 1400 IOPS for random 4 KB writes, measured under JEDEC-defined conditions (queue depth 32, 100% write, steady-state). Performance remains stable across temperature and lifetime due to background wear leveling and SLC caching in user partitions.

Can the RPMB partition be reprogrammed after initial provisioning?

No - RPMB authentication keys are written once during manufacturing and cannot be altered. Subsequent RPMB access requires HMAC-SHA256 challenge-response authentication using the stored key; no mechanism exists to overwrite or reset the key in the field.
