Infineon Technologies S40410081B1B2I000

Overview

S40410081B1B2I000 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), housed in a 153-ball VFBGA (13 mm × 11.5 mm × 1.0 mm). It delivers 120 MB/s sequential read and 20 MB/s sequential write in HS200/x8 mode, supports boot partitions, RPMB, and hardware reset, and is rated for industrial temperature (−40 °C to +85 °C).

For engineers reviewing the S40410081B1B2I000 datasheet, S40410081B1B2I000 pinout, S40410081B1B2I000 application, or S40410081B1B2I000 equivalent, key selection criteria include HS200 timing compliance, RPMB partition support, boot operation capability, industrial temperature rating, and 153-ball VFBGA mechanical compatibility.

Technical Context

This e.MMC device implements JEDEC JESD84-B451 architecture with dedicated boot partitions (4 MB each), a 4 MB Replay Protected Memory Block (RPMB), and configurable General Purpose Partitions. Its controller integrates wear-leveling, ECC, garbage collection, and defect management over MLC NAND flash.

It supports three operational modes: SDR (up to 52 MHz), DDR (up to 52 MHz), and HS200 (up to 200 MHz) on x4 or x8 data buses, with hardware reset (RST_N), high-priority interrupt (HPI), and background operations enabled via EXT_CSD register configuration.

FAQ

What is the factory default configuration of boot and RPMB partitions?

The S40410081B1B2I000 ships with two 4 MB boot partitions and one 4 MB RPMB partition, all pre-configured in Enhanced (SLC) mode for maximum reliability. These sizes and modes are fixed at factory and cannot be altered post-shipment.

Does this device support power-loss protection during write operations?

Yes-it implements hardware-assisted power-off notification (via CMD12 with specific arguments) and uses SLC-enhanced partitions for critical firmware areas. The controller guarantees atomic sector writes and maintains internal state integrity during abrupt VCC dropout within specified timing windows.

Can the General Purpose Partitions be resized after initial programming?

No. Partition sizes and enhancement modes (SLC/MLC) for General Purpose Partitions are one-time programmable via EXT_CSD register writes. Once configured, these attributes are locked permanently and cannot be modified in the field.

Is HS200 mode compatible with standard e.MMC 4.51 host controllers?

Yes-HS200 is defined in JEDEC JESD84-B451 and supported by all compliant host controllers. The S40410081B1B2I000 enters HS200 mode via standardized CMD6 command sequence and requires host-side tuning of signal integrity parameters per AC timing tables.
