Product details
Overview
USB2240-AEZG-06 from Microchip Technology is a USB 2.0 Hi-Speed bulk-only flash media controller IC supporting xD-Picture Card, Memory Stick, and multiplexed SD/MMC interfaces in a single 36-pin QFN package. It integrates an 8051 core (60 MHz), 64 KB ROM/14 KB RAM, on-chip 1.8 V regulator, and internal 200 mA card power FET. It delivers sustained transfer rates >35 MB/s in compatible host/media configurations and targets combo-card reader designs for desktop PCs and printers.
For engineers reviewing the USB2240-AEZG-06 datasheet, USB2240-AEZG-06 pinout, USB2240-AEZG-06 application, or USB2240-AEZG-06 equivalent, this page provides verified technical context, validated pin functions, confirmed media protocol support (xD 1.2, MS 1.43/Pro 1.02/Duo 1.10), exact package mapping (6×6 mm QFN), and two documented alternative parts with functional and interface-level differences.
Technical Context
The USB2240-AEZG-06 implements a hardware-controlled data flow architecture optimized for self-mapped flash media including xD-Picture Card and Memory Stick, with pipelined hardware acceleration for non-self-mapped access. Its integrated 8051 processor executes at 60 MHz with single-cycle instruction timing and manages media-specific command protocols (e.g., xD_CLE/xD_nWE, MS_BS/MS_SCLK) directly via dedicated I/O buffers.
It supports dual-voltage operation: a single 3.3 V supply powers digital I/O and analog circuits (VDD33, VDDA33), while internal regulators generate 1.8 V for core logic (VDD18) and PLL (VDD18PLL). The device includes integrated USB 2.0 transceiver bias (RBIAS), crystal driver (XTAL1/XTAL2), and configurable media activity LED control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash media controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| USB2241-AEZG-06 | Omits xD-Picture Card interface pins; adds dedicated SD/MMC + Memory Stick pin separation; same 36-pin QFN package and 8051 core | Targeted for SD+MS-only combo sockets; no xD support; simplified layout for non-xD designs | Select when xD compatibility is unnecessary and SD/MMC+MS coexistence requires dedicated routing |
| USB2244-AEZG-06 | Removes xD and Memory Stick interfaces entirely; dedicated 12-pin SD/MMC interface; no multiplexing; supports SD Secure licensing | Optimized for high-volume SDHC/SDXC readers only; excludes xD/MS legacy formats | Select for cost-sensitive SD-only applications where secure media features (SD Secure) are required |
Compared with USB2240-AEZG-06, USB2241-AEZG-06 removes xD support but retains multiplexed SD/MS capability, while USB2244-AEZG-06 abandons multiplexing entirely for a fixed SD-only interface with enhanced security licensing - making USB2240-AEZG-06 the only variant supporting xD-Picture Card in this family.

FAQ
What flash media formats does USB2240-AEZG-06 natively support?
USB2240-AEZG-06 natively supports xD-Picture Card 1.2, Memory Stick 1.43/Pro 1.02/Duo 1.10, and multiplexed SD/MMC interfaces. It does not support TransFlash or reduced-form-factor SD variants beyond HS-SD and SDHC compliance per DS00001979A. The USB2240-AEZG-06 implements dedicated hardware logic for xD command protocols (xD_CLE/xD_nWE) and MS bus-state control (MS_BS), confirming full format-level compatibility.
Does USB2240-AEZG-06 require an external crystal or can it use an oscillator?
USB2240-AEZG-06 supports both configurations: a 24 MHz crystal connected between XTAL1 and XTAL2, or an external 24 MHz clock source applied solely to XTAL1 (with XTAL2 left open). The internal crystal driver circuit eliminates need for external buffer components. This flexibility is explicitly documented in Section 6.1 of DS00001979A for USB2240/40I variants like USB2240-AEZG-06.
What is the maximum current capability of the CRD_PWR pin on USB2240-AEZG-06?
The CRD_PWR pin on USB2240-AEZG-06 delivers up to 200 mA at 3.3 V with integrated fold-back short-circuit protection. This is confirmed in the Hardware Features section of DS00001979A and applies specifically to USB2240/40I devices. The protection mechanism limits current during overloads without requiring external current-limiting components, simplifying design for xD/MS/SD card power delivery.
Is USB2240-AEZG-06 pin-compatible with other USB224x variants?
No - USB2240-AEZG-06 is not pin-compatible with USB2241-AEZG-06 or USB2244-AEZG-06. Although all share the same 36-pin QFN package, pin functions differ significantly: USB2240-AEZG-06 assigns xD-specific signals (xD_D[7:0], xD_nWP) to shared pins used for SD/MS in other variants. DS00001979A Figures 4-1 through 4-3 confirm distinct pin mappings across the family.
What operating systems support USB2240-AEZG-06 out-of-the-box?
USB2240-AEZG-06 is supported natively by Microsoft Windows XP/ME/2000 SP4, Windows Vista (including ReadyBoost), Apple macOS, and Linux mass storage class drivers. This compatibility stems from its adherence to USB 2.0 bulk-only mass storage class specification and default VID/PID (0424h/2240h) registered with USB-IF - verified in Section 7.2.2 and Applications sections of DS00001979A.
