Product details
Overview
SEC2410-JZX from SMSC is a USB 2.0-compliant, high-speed bulk-only mass storage class peripheral controller integrating an ARM Cortex-M3 processor (60 MHz), SD/MMC flash media interface, SmartCard (ISO/IEC 7816), AES encryption engine, and on-chip 3.3 V to 1.2 V regulation. It delivers sustained transfer rates exceeding 35 MB/s with SDHC/SDXC (SDR25) and eMMC 4.4 support, targeting secure token and embedded media reader applications.
For engineers reviewing the SEC2410-JZX datasheet, SEC2410-JZX pinout, SEC2410-JZX application, or SEC2410-JZX equivalent, key selection criteria include its 64-pin QFN (9×9 mm) package, industrial-grade temperature range (0°C to +85°C), dual SD/MMC interface capability, integrated 200 mA card power FET with fold-back protection, and hardware-accelerated AES-128/192/256 in ECB/CBC/CTR modes.
Technical Context
The SEC2410-JZX implements a pipelined hardware architecture for non-self-mapped media access and hardware-controlled data flow for self-mapped media, enabling deterministic latency and high throughput. Its integrated ARM M3 core executes at 60 MHz (1 cycle/instruction minimum) with 96 KB SRAM for code execution and 32 KB internal ROM, supporting firmware upgrades via USB bus without boot block flash.
It embeds a full USB 2.0 transceiver with integrated D+/D− termination and pull-up/down resistors, eliminating external components. The device supports SDIO streaming mode, Secure Digital Pass-Through, SD Security Command Extensions, and optional external 24 MHz clock input or on-board crystal driver - all while operating from a single 3.3 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Compliance | Fully compliant with USB 2.0 specification; includes integrated transceiver, series termination, and pull-up/down resistors - no external PHY required. |
| Processor Core | ARM Cortex-M3 @ 60 MHz min (1-cycle/instruction); 96 KB SRAM for code, 32 KB ROM, 32 KB scratchpad SRAM - enables standalone firmware execution. |
| Flash Media Support | SD 2.0 (HS-SD, SDHC, SDXC SDR25), MMC v4.2 (1/4/8-bit), eMMC v4.4; no UHS-I/UHS-II or SDR50/SDR100 - limits max SD speed to 50 MB/s theoretical. |
| Cryptographic Engine | Hardware AES-128/192/256 with ECB/CBC/CTR modes; zero performance impact during encryption/decryption of mass storage traffic. |
| Power Management | Single 3.3 V supply input; internal 1.2 V core regulator eliminates need for external DC-DC or LDO - reduces BOM count and PCB area. |
| GPIO Capability | Up to 32 configurable GPIOs; one dedicated 200 mA drive pin with fold-back short-circuit protection for direct card power control. |
| Package & Temp | 64-pin QFN (9×9 mm), RoHS-compliant; rated for 0°C to +85°C ambient - suitable for commercial and extended-temperature embedded systems. |
Pinout & Package
SEC2410-JZX is housed in a 64-pin QFN package (9×9 mm, 0.5 mm pitch) with exposed thermal pad connected to VSS. Pin functions are validated per SMSC SEC2410 datasheet Rev. 1.0 (pp. 9–19), confirming 64 total pins including five VDD33 supplies, dedicated SD1/SD2 interfaces (24 pins total), SmartCard (8 pins), SPI (4 pins), USB (7 pins), JTAG (5 pins), UART (2 pins), and 32 GPIO-capable terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| USBDP / USBDM | USB 2.0 Differential Data Pair | Direct connection to upstream host USB port; integrated termination and biasing eliminate external resistors. |
| SD1_CMD / SD1_CLK / SD1_D[0:7] | Primary SD/MMC Interface | Full 8-bit SD command/data bus supporting HS-SD, SDHC, SDXC (SDR25), and eMMC 4.4 - enables high-bandwidth card access. |
| SD2_CMD / SD2_CLK / SD2_D[0:7] | Secondary SD/MMC Interface | Independent dual-slot capability; supports simultaneous read/write to two cards - critical for redundant storage or multi-format readers. |
| VAR_CRD_PWR / GPIO10 | Variable Voltage Card Power Driver | 200 mA output with fold-back short-circuit protection; programmable voltage (1.8/3.0/3.3 V) for SD/SDIO/eMMC compatibility. |
| JTAG_TMS/TDO/TDI/TCK/TRST | ARM Debug Interface | Standard 5-pin JTAG for firmware development, boundary scan, and production programming - no debug adapter required beyond standard tools. |
| GPIO0–GPIO31 (multiplexed) | Configurable I/O Bank | 32 pins support LED indicators, button inputs, card detect (nCD), write protect (WP), UART, and custom logic - reduces need for external glue logic. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated USB 2.0 Transceiver | Eliminates external PHY, termination resistors, and pull-up/down components - reduces BOM cost and layout complexity by ≥7 parts. |
| Dual SD/MMC Controller | Enables concurrent operation on two independent flash media slots - supports RAID-like redundancy or mixed-format readers (e.g., SD + microSD). |
| Hardware AES Encryption | Offloads encryption/decryption from CPU; maintains full 480 Mbps USB bandwidth during AES-256 CBC operations - essential for secure token compliance. |
| On-Chip 1.2 V Regulator | Derives core voltage from single 3.3 V rail - removes need for external 1.2 V LDO, saving PCB space and improving power delivery stability. |
| SmartCard Interface (ISO/IEC 7816) | Supports 3 V/1.8 V card voltages with integrated level-shifting and protocol handling - enables combined secure token + storage devices in one SoC. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-to-flash-media controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SEC4410-JZX | Same core architecture but adds HSIC interface and 1.2 V reference; 72-pin QFN only; no 64-pin variant available. | Targeted at HSIC-based host systems (e.g., mobile SoCs); lacks SEC2410-JZX's USB-only simplicity and smaller footprint. | Select SEC4410-JZX only if HSIC connectivity and trace debugging (TRACEDATAx/TRACECLK) are required - not a drop-in replacement. |
| GL827L | Dedicated USB 2.0 SD/MMC reader IC; no ARM core, no SmartCard, no AES; lower cost, fixed-function design. | Limited to basic card reading; cannot run custom firmware or support secure token use cases requiring cryptographic processing. | Choose GL827L for cost-sensitive, non-secure readers where firmware flexibility and encryption are unnecessary. |
Compared with SEC4410-JZX and GL827L, SEC2410-JZX uniquely balances programmability (ARM M3), security (AES + SmartCard), and compactness (64-pin QFN), making it optimal for secure, field-upgradable embedded storage solutions where board space and cryptographic integrity are critical.

FAQ
What is the maximum SD card speed supported by SEC2410-JZX?
The SEC2410-JZX supports SDXC in SDR25 mode only, with no UHS-I (SDR50/SDR100) or UHS-II capability. This limits theoretical peak transfer to 125 MB/s, though real-world sustained rates exceed 35 MB/s depending on media and host capabilities. SDHC and MMC v4.2 (1/4/8-bit) are also fully supported.
Does SEC2410-JZX require an external crystal or can it use an oscillator?
The SEC2410-JZX supports both options: an external 24 MHz crystal connected across XTAL1/XTAL2, or an external 24 MHz CMOS oscillator applied to XTAL1/CLKIN (with XTAL2 unused). The on-chip crystal driver circuit eliminates need for external load capacitors when using a crystal.
Can SEC2410-JZX operate with only one SD interface enabled?
Yes - SEC2410-JZX supports multiple configurations including SD-only, dual SD, SD+SmartCard, or GPIO-only modes. Configuration is set at boot via SPI ROM or USB, allowing flexible system design without hardware changes. SD2 pins default to GPIO when unused.
Is SEC2410-JZX compatible with Windows, macOS, and Linux out of the box?
Yes - SEC2410-JZX is certified for Microsoft Windows (XP, Vista, 7, 2K SP4), Apple macOS X 10.x, and Linux Mass Storage Class drivers. No custom drivers are needed; it enumerates as a standard USB Mass Storage device supporting Multi-LUN operation.
What debug interfaces does SEC2410-JZX provide?
SEC2410-JZX provides a full 5-pin JTAG interface (TMS/TDO/TDI/TCK/TRST) compatible with standard ARM debug tools. It does not include SWD or trace pins (TRACEDATAx/TRACECLK), which are exclusive to the 72-pin SEC2410-AKZE and SEC4410 variants.
